[Solution] In one aspect of the present invention, a schedule suggestion system calculates and determines whether to shift the user's internal clock forward or backward based on time difference information, attribute information, and flight schedule information. It sets the sleep time after travel as the sleep time in the habitual sleep schedule, generates a sleep schedule that gradually shifts the sleep time in the adjustment direction from the adjustment start date to the flight departure date, displaces the pre-stored core body temperature fluctuation pattern to match the sleep time shifted in the adjustment direction, and calculates the lowest core body temperature time for each day based on the displaced fluctuation pattern. Based on the calculated lowest body temperature time, the system determines the optimal light schedule and exercise schedule.

[0010] Hereinafter, a schedule proposal system for maintaining athletic performance and a schedule proposal method for maintaining athletic performance to which the present invention is applied will be described with reference to the drawings.

[0011] <Overview of Embodiment> Figure 1 is a block diagram illustrating an example of a schedule proposal system 100 according to an embodiment. The schedule proposal system 100 according to the embodiment is a schedule proposal system for maintaining athletic performance that creates action schedule information including actions and action execution timings for at least one of reduction of fatigue caused by overseas travel, alleviation of jet lag symptoms, and infectious disease countermeasures based on the user's flight schedule information and attribute information, and proposes the action schedule information capable of maintaining athletic performance at a higher state to the user. Athletic performance often deteriorates due to reduced physical condition during overseas travel. In response to this, according to the schedule proposal system 100, the expected deterioration of the user's physical condition can be prevented, and even if the user's physical condition deteriorates, the deterioration can be alleviated or recovered, and as a result, the athletic performance after overseas travel can be maintained at a higher state. Further, the user in the present embodiment is a sports athlete who travels overseas and is required to demonstrate maximum athletic performance on the date of the competition at the travel destination, or related staff thereof. Athletic performance refers to behavioral ability in exercise, including at least one element among muscle strength, endurance, speed, agility, coordination, skill, accuracy, and stability of mental strength.

[0012] The schedule proposal system 100 proposes, for example, sleep duration during the user's overseas travel, jet lag countermeasures, fatigue countermeasures during travel, infectious disease countermeasures, training schedule adjustment, and the like. In particular, the schedule proposal system 100 proposes an action schedule including actions related to conditioning for athletes to demonstrate good performance after overseas travel and execution timings of the actions. Furthermore, the schedule suggestion system 100 can also suggest to the user information on infectious diseases in the destination country, infection prevention information indicating actions to take for infection prevention measures on board the aircraft and at the destination country, and pre-travel infection prevention schedule information including preparations for infection prevention measures before travel and the timing of carrying out those preparations. Furthermore, the schedule suggestion system 100 can also suggest training schedule information to the user, including training from before departure until the day of the match, and the timing of when the training will be performed. The schedule suggestion system 100 can contribute to maintaining athletes' athletic performance at a higher level by providing users such as athletes with activity schedules, infection prevention schedules, and training schedules. The following provides a detailed explanation of this schedule proposal system 100.

[0013] <Configuration of Schedule Proposal System 100> The schedule suggestion system 100 is connected, for example, to one or more mobile terminal devices 200A, 200B (hereinafter collectively referred to as "mobile terminal device 200") via a communication network. The schedule suggestion system 100 and the mobile terminal device 200 are equipped with communication interfaces such as NICs (Network Interface Cards) and wireless communication modules (not shown in Figure 1). The communication network includes, for example, the Internet, WANs (Wide Area Networks), LANs (Local Area Networks), and cellular networks.

[0014] Mobile terminal device 200A is an information processing device such as a smartphone held by the team administrator. Mobile terminal device 200B is an information processing device such as a smartphone held by a team member. Mobile terminal device 200 may be a stationary personal computer, a notebook computer, or a tablet device. The athlete user can be either the team administrator or a team member.

[0015] The mobile terminal device 200 includes, for example, a user interface, a memory unit, a GPS processing unit, and a processor. The mobile terminal device 200 launches a User Agent (UA), such as a browser or an application program. The UA is, for example, an application for communicating with the schedule suggestion system 100.

[0016] The schedule proposal system 100 is an information processing device that performs various processes in response to requests received from a mobile terminal device 200. The schedule proposal system 100 includes, for example, an acquisition unit 110, an information creation unit 120, and a transmission unit 130. The schedule proposal system 100 may be located on the cloud, or it may be implemented by one or more computers reading and executing a program. The schedule proposal system 100 includes memory and a processor. The memory stores instructions when they are executed by the processor. The processor is a CPU (Central Processing Unit). The processor may also be an MPU (Microprocessing Unit), GPU (Graphics Processing Unit), NPU (Neural Network Processing Unit), TPU (Tensor Processing Unit), AI accelerator, ASIC for Tensor processing, etc. The processor reads programs and various data from a drive via memory and performs calculations to execute instructions stored in one or more memories.

[0017] The acquisition unit 110 functions as a flight schedule acquisition unit, a date and time information acquisition unit, a time difference information acquisition unit, and an attribute information acquisition unit, acquiring various types of information from the mobile terminal device 200 or an external device. The acquisition unit 110 acquires flight schedule information and attribute information. Flight schedule information includes departure date and time information, arrival date and time information, departure location information, and destination information for the flights used by the user for travel. Attribute information includes physical characteristics such as the user's habitual sleep schedule and time orientation (chronotype). Date and time information includes the start and end dates and times of the user's condition adjustments during overseas travel. Time difference information is the time difference information during the user's overseas travel, indicating the time difference between the departure location and the arrival location.

[0018] The information creation unit 120 creates activity schedule information, which includes at least the user's activities, including sleep, and the timing of when those activities are performed, based on the information obtained by the flight schedule acquisition unit, the date and time information acquisition unit, the time difference information acquisition unit, and the attribute information acquisition unit. The information creation unit 120 may create action schedule information, including actions and timing for performing at least one of the following: reducing fatigue from overseas travel, reducing jet lag symptoms, or taking precautions against infectious diseases, based on the flight schedule information acquired by the acquisition unit 110. Actions to reduce fatigue from overseas travel and actions to reduce jet lag symptoms include, for example, sleep, exercise, eating, caffeine intake, and sunbathing. Actions to prevent infectious diseases include information on infectious diseases in the destination country, preparation of infection prevention measures before travel (preparation of vaccinations, insect repellent sprays, etc.), hand washing and hand sanitizing during travel, and caution regarding food and water. The action schedule information includes information on the time periods in which actions are recommended. Note that during travel, this includes time spent on the aircraft and time spent at the destination country.

[0019] The following is an example of the specific processing flow in the exercise performance maintenance schedule proposal system according to this embodiment. First, the user inputs information regarding the period for which exercise performance should be maintained and travel plans to the exercise performance maintenance schedule suggestion system via the acquisition unit 110. For example, the user inputs date and time information such as the adjustment start date to be March 30th (Japan time), departure date and time to be April 2nd (Japan time), arrival date and time to be April 2nd (Los Angeles time), and adjustment end date to be April 6th (Los Angeles time), as well as flight schedule information. In addition to this, the user inputs their own attribute information, including their sleep schedule, which includes their habitual bedtime and wake-up time. Next, the information creation unit 120 calculates the time difference information from the date and time information and the flight schedule information. Furthermore, using the input habitual sleep schedule as a starting point, it mechanically calculates how to adjust the sleep schedule by a predetermined amount of time each day during the pre-departure adjustment period from March 30th to April 2nd. After arrival, it also sets the system to maintain the habitual sleep schedule in local time. The direction of the circadian rhythm adjustment (phase advance or regression) is processed and determined by calculations based on the input time difference information and flight schedule information. Furthermore, the information creation unit 120 processes the calculated pre- and post-travel sleep schedules, the minimum body temperature time obtained from the habitual sleep schedule, time difference information, and arrival date and time (flight schedule information) through calculations, and estimates the minimum core body temperature time for each day during the adjustment period. Finally, the information generation unit 120 determines the optimal light and exercise schedules based on the calculated minimum body temperature time. At this time, the timing of light exposure and shielding is set in accordance with the determined direction of adjustment of the biological rhythm (phase advance or regression). This makes it possible to show, at the user-specified adjustment end date, how well the biological rhythm (circadian rhythm) matches or deviates from the social schedule of the destination. As a result, the user can understand the degree of jet lag symptoms associated with travel in advance and obtain specific action guidelines to maintain exercise performance during the target local schedule.

[0020] The transmission unit 130 transmits the activity schedule information created by the information creation unit 120 to the user's mobile terminal device 200.

[0021] Figure 2 shows the flow of how an individual user uses the schedule suggestion system 100 in this embodiment. If the user is an athlete, the athlete inputs attribute information, date and time information, and flight schedule information by operating the mobile terminal device 200B. Attribute information includes personal information such as the athlete's name, gender, age, physical information, habitual sleep schedule, and sport. Date and time information includes information such as the start date and time of conditioning, the date and time of the match (end date of conditioning), and the departure date and time from the destination. Flight schedule information identifies the airport and flight the athlete will take for the match (departure city, destination, departure date and time, arrival date and time). The schedule suggestion system 100 receives information from the mobile terminal device 200B, acquires the attribute information, date and time information, and flight schedule information, and stores them in the storage device 300.

[0022] Figure 3 is a diagram illustrating the flow of movement when an individual or group of users moves according to the instructions of the administrator in the embodiment. When a player travels individually, the administrator grants the player administrator privileges. For example, the mobile terminal device 200A transmits information about the player to whom administrator privileges are to be granted in response to the administrator's operation to the schedule proposal system 100. As a result, the schedule proposal system 100 grants administrator privileges to the mobile terminal device 200B held by the player. As shown in Figure 2, the player inputs attribute information, match date and time information, flight information, and adjustment start date information by operating the mobile terminal device 200B, and the schedule proposal system 100 receives the information from the mobile terminal device 200B. The schedule proposal system 100 creates schedule information based on the information received from the mobile terminal device 200B. The mobile terminal device 200B can check the schedule by obtaining the schedule information from the schedule proposal system 100.

[0023] When a group travels, the administrator shares flight information with each athlete in the group. For example, mobile terminal device 200A transmits flight information to an individual athlete's mobile terminal device 200B. Mobile terminal device 200A also transmits information about the athletes included in the group and the group's flight schedule information to the schedule suggestion system 100, which stores the information about the athletes included in the group and the group's flight schedule information in the storage device 300. Athletes input attribute information, match date and time information, and adjustment start date information by operating mobile terminal device 200B, and the schedule suggestion system 100 receives the information from mobile terminal device 200B. Based on the information received from the individual athlete's mobile terminal device 200B, the schedule suggestion system 100 creates schedule information for each athlete. Mobile terminal device 200B can check its individual schedule by obtaining the schedule information from the schedule suggestion system 100.

[0024] Figure 4 is a flowchart showing an example of the processing procedure of the schedule proposal system 100 in the embodiment. First, the schedule suggestion system 100 determines whether attribute information has already been entered from the mobile terminal device 200 (step S100). The attribute information consists of habitual sleep schedule information and physical information. If the attribute information has already been entered (step S100: YES), the schedule suggestion system 100 proceeds to step S108; if the attribute information has not been entered (step S100: NO), it proceeds to enter the attribute information (step S102).

[0025] In step S102, the schedule suggestion system 100 sends a message to, for example, the mobile terminal device 200 requesting the input of attribute information. The mobile terminal device 200 sends physical information to the schedule suggestion system 100 in response to the request from the schedule suggestion system 100, and the schedule suggestion system 100 acquires the physical information (step S104). The mobile terminal device 200 sends a habitual sleep schedule to the schedule suggestion system 100 in response to the request from the schedule suggestion system 100, and the schedule suggestion system 100 acquires the habitual sleep schedule (step S106). The habitual sleep schedule is information such as the user's habitual bedtime and wake-up time, or sleep duration.

[0026] Next, in step S108, the schedule suggestion system 100 accepts input of travel information (step S108). The travel information includes information including the start and end dates and times of condition adjustment, flight schedule information, user location information, and time zone information. The user location information and time zone information are calculated from the flight schedule information and may be calculated by the mobile terminal device 200 or by the schedule suggestion system 100. The schedule suggestion system 100 may obtain travel information by requesting it from the mobile terminal device 200, or it may obtain information already recorded in the storage device 300 as travel information.

[0027] The schedule suggestion system 100 acquires information including the start date and end date and time of condition adjustment in step S110, acquires flight schedule information in step S112, acquires the user's location information in step S114, and acquires time difference information in step S116.

[0028] The schedule suggestion system 100 creates activity schedule information based on physical information, habitual sleep schedule before travel, start and end dates and times for condition adjustment, flight schedule information, user location information, and time zone information (step S118). The user's location information may be location information obtained from a mobile terminal device 200, location information obtained from the user's flight schedule, or location information of the user's accommodation, training facility, match facility, etc. Next, the schedule suggestion system 100 transmits the created action schedule information to the mobile terminal device 200 (step S120).

[0029] Figure 5 is a block diagram showing an example of the functions of the information creation unit 120 in the embodiment. The information creation unit 120 includes, for example, an adjustment direction calculation unit 400, a minimum body temperature time calculation unit 402, a sleep schedule calculation unit 404, a meal schedule calculation unit 406, a light schedule calculation unit 408, an exercise schedule calculation unit 410, a travel fatigue countermeasure calculation unit 412, a caffeine intake schedule calculation unit 414, and an infectious disease countermeasure calculation unit 416. Although Figure 5 shows the connection relationships of each unit as an example, it is not limited to this, and processing may be performed using information input and output by each unit.

[0030] The adjustment direction calculation unit 400 calculates and determines whether to adjust the sleep period forward or backward in order to bring the user's internal clock closer to the circadian rhythm based on the time difference information acquired by the time difference information acquisition unit and the flight schedule information acquired by the flight schedule acquisition unit. The adjustment direction calculation unit 400 may also adjust the schedule information forward or backward based on the attribute information acquired by the attribute information acquisition unit. For example, since the perception of time difference differs depending on physical information such as internal clock, age, sleep habits, and health status, it is desirable for the adjustment direction calculation unit 400 to adjust the forward or backward direction according to the physical information. The adjustment direction calculation unit 400 shifts the sleep period forward or backward based on the time difference information.

[0031] Figure 6(A) shows an example of a schedule for day 1, and Figure 6(B) shows an example of a schedule for day 2. Forward adjustments involve, for example, if the habitual sleep time is from 23:00 to 7:00, calculating the behavioral schedule information to gradually shift the sleep time forward by changing the sleep time in the behavioral schedule information to 22:30 to 6:30. Conversely, backward adjustments involve, for example, if the habitual sleep time is from 23:00 to 7:00, calculating the behavioral schedule information to gradually shift the sleep time backward by changing the sleep time in the behavioral schedule information to 23:30 to 7:30.

[0032] Specifically, the adjustment direction calculation unit 400 calculates whether the user's sleep time should be adjusted forward (advancing) or backward (delaying) based on the time difference information between the destination and departure point acquired by the time difference information acquisition unit and the arrival time at the destination acquired by the flight schedule acquisition unit. For example, if the local time at the destination is ahead of the local time at the departure point, the adjustment direction calculation unit 400 may decide to adjust the user's sleep schedule forward. On the other hand, if the local time at the destination is behind the local time at the departure point, the adjustment direction calculation unit 400 decides to shift it backward.

[0033] For example, if the time difference between the departure point and the destination is 8 hours and the usual sleep time is from 23:00 to 7:00, the adjustment direction calculation unit 400 will perform a process to present a sleep schedule that is shifted forward by 20 to 30 minutes each day from the adjustment start date until departure.

[0034] The minimum body temperature time calculation unit 402 calculates the time of the lowest core body temperature. The minimum body temperature time calculation unit refers to the core body temperature fluctuation pattern of a user or a typical individual that is stored in the memory device (information that can be obtained from the habitual sleep schedule acquired from the attribute information acquisition unit). The minimum body temperature time calculation unit 402 calculates the time when the core body temperature is lowest each day (minimum body temperature time) by shifting the core body temperature fluctuation pattern in the adjustment direction to match the sleep time period adjusted by the sleep schedule calculation unit 404. Core body temperature fluctuates periodically according to the circadian rhythm, and its lowest point is closely related to sleep. The minimum body temperature time calculation unit 402 estimates the natural rhythmic changes during the adjustment period by shifting the fluctuation pattern along the time axis to match the adjusted sleep schedule.

[0035] The time of lowest core body temperature is the time of day when the body's core body temperature is at its lowest. The minimum core body temperature calculation unit 402 calculates the minimum core body temperature based, for example, the adjustment direction calculated by the adjustment direction calculation unit 400, the habitual sleep schedule, the time difference, and the flight schedule information. The minimum core body temperature calculation unit 402 calculates different minimum core body temperature times for day 1 and day 2, for example, by adjusting the sleep time according to the adjustment direction. The minimum core body temperature calculation unit 402 also calculates the minimum core body temperature considering, for example, that the habitual sleep schedule may shift due to the flight schedule information and the time difference. The minimum core body temperature calculation unit 402 may also use input from the user themselves or the results measured by a device that measures core body temperature.

[0036] The sleep schedule calculation unit 404 sets the sleep time after travel as the sleep time in the habitual sleep schedule and generates a sleep schedule that gradually adjusts the sleep time in the direction of adjustment from the adjustment start date to the adjustment end date. For example, if the user's usual bedtime is 11pm and wake-up time is 8am, when the adjustment direction is forward, the bedtime and wake-up time are changed to advance by a certain amount of time each day from the adjustment start date, and the schedule is formed so that the circadian rhythm after travel comes as close as possible to a schedule that is suitable for the local time by the departure date of the flight obtained from the flight schedule information. In addition, if the amount of shift is large, the maximum amount of time that can be shifted in one day is set as the upper limit, and the transition is carried out in stages within a reasonable range. The sleep schedule calculation unit 404 basically only shifts the sleep time before travel, and after travel, it may present the habitual sleep time.

[0037] The sleep schedule calculation unit 404 may calculate a sleep schedule during the trip that includes recommended sleep time periods or recommended nap time periods. The sleep schedule calculation unit 404 calculates a sleep schedule during the trip based, for example, on the adjustment direction calculated by the adjustment direction calculation unit 400, the habitual sleep schedule, the time difference, the adjustment start date, the adjustment end date, and the flight schedule information. The sleep schedule calculation unit 404 calculates the first sleep time period on board the aircraft or upon arrival at the destination, for example, taking into account the time difference and the flight schedule information. The sleep schedule calculation unit 404 adjusts the sleep time after arrival to match the sleep time in the habitual sleep schedule.

[0038] The meal schedule calculation unit 406 calculates a meal schedule that includes recommended meal times. The meal schedule calculation unit 406 calculates a meal schedule during the trip based on the sleep schedule during the trip calculated by the sleep schedule calculation unit 404. The meal schedule calculation unit 406 obtains information indicating the sleep time during the trip calculated by the sleep schedule calculation unit 404 from the storage device 300, and creates a meal schedule during the trip by inserting recommended meal times into the time periods other than the obtained sleep time.

[0039] The light schedule calculation unit 408 calculates a light schedule during travel that includes time periods when light exposure is recommended or not recommended. The light schedule is the time periods when the user should be exposed to sunlight or other light, or when they should avoid it. The light schedule calculation unit 408 obtains information from the storage device 300 indicating the minimum body temperature time (the time period when core body temperature reaches its lowest value) calculated by the minimum body temperature time calculation unit 402, and calculates the light schedule during travel by performing a process to calculate the time periods when light exposure is recommended and when it is not recommended before and after the minimum body temperature time (the time period when core body temperature reaches its lowest value). Specifically, in the forward direction, light exposure is not recommended before the minimum body temperature time (the time period when core body temperature reaches its lowest value), and light exposure is recommended after the minimum body temperature time (the time period when core body temperature reaches its lowest value). Regarding the light schedule, it is not necessarily recommended to recommend light exposure before the time of lowest body temperature; depending on the adjustment direction, it may be recommended to recommend light exposure after the time of lowest body temperature.

[0040] The light schedule calculation unit 408 may calculate the optimal time to be exposed to light and the time to avoid light in order to reduce jet lag or adjust the internal clock, based on the time of lowest core body temperature and the sleep schedule. The light schedule calculation unit 408 can shift the internal clock forward or backward by exposing the user to or avoiding light before or after the time when the core body temperature reaches its lowest value. For example, to shift the internal clock forward, the schedule may be to expose the user to sunlight after waking up, and to shift the internal clock backward, the schedule may be to expose the user to high-intensity light in the evening.

[0041] The exercise schedule calculation unit 410 calculates the exercise schedule during the trip. Based on the information indicating the sleep time during the trip calculated by the sleep schedule calculation unit 404 and the information indicating the light schedule obtained from the light schedule calculation unit 408, the exercise schedule calculation unit 410 calculates the exercise schedule during the trip by inserting recommended exercise times. For example, the exercise schedule calculation unit 410 inserts recommended exercise times during the daytime at the destination (calculated from the sleep time) or at the same time as the time of exposure to light, and also inserts recommended exercise times that avoid the time before going to bed (for example, 2 hours). Furthermore, exercise schedules can generally be determined based on the light exposure schedule. This is because exercising during times when you are exposed to light makes it easier to adjust to the local schedule.

[0042] The exercise schedule calculation unit 410 may, for example, calculate an exercise schedule based on the sleep schedule during travel calculated by the sleep schedule calculation unit 404. The exercise schedule calculation unit 410 may also calculate an exercise schedule suitable for reducing fatigue and jet lag symptoms caused by overseas travel. For example, the exercise schedule calculation unit 410 can encourage a shift in the user's internal clock by calculating the time periods in which exercise can be performed in conjunction with the time periods when the user is exposed to light. The exercise schedule calculation unit 410 may also recommend time periods for exercise that are in order to shift the user to a time period when they can perform their exercise best, depending on the elapsed time since waking up.

[0043] The travel fatigue countermeasure calculation unit 412 calculates countermeasures for fatigue caused by overseas travel. Fatigue caused by overseas travel refers to exhaustion and fatigue caused by long-distance travel or repeated travel, regardless of the mode of transport, direction of travel, or time difference with the destination. Examples include fatigue, mood swings, and decreased attention and motivation. Countermeasures for fatigue caused by overseas travel include ensuring sufficient sleep and nutrition, staying well-hydrated by drinking plenty of fluids on the plane, wearing recommended clothing, and exercising to promote blood flow, such as stretching or walking. The travel fatigue countermeasure calculation unit 412 calculates travel fatigue countermeasures based, for example, on sleep schedules, adjustment start dates, adjustment end dates, and flight schedule information to alleviate fatigue caused by overseas travel. The travel fatigue countermeasure calculation unit 412 proposes actions to alleviate travel fatigue in relation to the sleep schedule. The travel fatigue countermeasure calculation unit 412 also calculates actions and timings for various countermeasures to alleviate travel fatigue during the period from the adjustment start date to the adjustment end date, calculated from the flight schedule.

[0044] The travel fatigue countermeasure calculation unit 412 obtains information indicating the sleep time during travel, calculated by the sleep schedule calculation unit, as well as departure and arrival time information for flights obtained by the flight schedule acquisition unit, from the storage device. Furthermore, the travel fatigue countermeasure calculation unit 412 obtains table data of flight travel time and travel fatigue countermeasure information that is pre-stored in the storage device 300. The travel fatigue countermeasure information in the table data may be information for recommending travel fatigue countermeasures, such as the content, type, and duration of travel fatigue countermeasures. The travel fatigue countermeasure calculation unit 412 then searches whether the travel time calculated based on the flight departure and arrival time information obtained by the flight schedule acquisition unit corresponds to any of the travel times stored in the storage device 300, reads the travel fatigue countermeasure information associated with the corresponding travel time from the table data, and performs a process to present the read travel fatigue countermeasure information. The process of presenting the travel fatigue countermeasure information may, for example, involve inserting the content of travel fatigue countermeasures, recommended timing, recommended time slots, prohibited time slots, etc., in between other schedules such as sleep.

[0045] The table data, for example, sets a 2-hour nap as travel fatigue countermeasure time if the flight travel time is 5 to 10 hours, and a 3-hour nap as travel fatigue countermeasure time if the flight travel time is 10 to 15 hours. The sleep prohibition period set before the sleep period is, for example, 5 hours counting back from the start time of the sleep period. The travel fatigue countermeasure calculation unit 412 can set the nap time if the nap time for the flight travel time can be inserted 5 hours before the start time of the sleep period. Specifically, it obtains the start time of the main sleep (20:00) from the storage device 300, subtracts the 5-hour sleep prohibition period from 20:00 and sets the end time of the nap (15:00), and if the travel time is 8 hours, a 2-hour nap time can be set. If the end time of the travel time is after 13:00, a 2-hour nap time can be set. If the end time of the travel time is after 13:00, the nap time can also be shortened and the main sleep time increased. It is also possible to dynamically correct the numerical values ​​of the table data based on the habitual schedule and time orientation (chronotype) obtained from the attribute information acquisition unit.

[0046] The caffeine intake schedule calculation unit 414 calculates the caffeine intake schedule during travel by inserting a predetermined time period before the sleep period calculated by the sleep schedule calculation unit 404 as a time period during which caffeine intake is not recommended, and inserting a time period during which caffeine intake is recommended, calculated from the sleep period calculated by the sleep schedule calculation unit 404 and the time when the core body temperature reaches its lowest value, as calculated by the minimum body temperature time calculation unit 402. The storage device 300 stores, for example, the start or end time of the sleep period, the recommended time for caffeine intake (5 hours after the end of sleep), and the non-recommended time (6 hours before the start of sleep). The caffeine intake schedule calculation unit 414 obtains the start or end time of sleep and outputs the recommended and non-recommended time for caffeine intake. Furthermore, the recommended time for caffeine intake is set to suppress drowsiness caused by the discrepancy between the circadian rhythm, based on the estimated time of lowest core body temperature, and the local social schedule. Specifically, recommendations are made by identifying time periods that should compensate for the decrease in alertness levels caused by the shift in biological rhythms. On the other hand, the time periods when caffeine intake is not recommended are set as predetermined periods calculated backward from the planned time to fall asleep, taking into account the time required to maintain blood concentration after intake, so as not to interfere with the quality of primary sleep at night.

[0047] The caffeine intake schedule calculation unit 414 may calculate a caffeine intake schedule during travel, including recommended and unrecommended times for caffeine intake, based on flight schedule information and the sleep schedule during travel calculated by the sleep schedule calculation unit 404. The caffeine intake schedule calculation unit 414 can reduce jet lag symptoms by adjusting the timing of caffeine intake. For example, the caffeine intake schedule calculation unit 414 can help reduce travel fatigue by limiting caffeine intake during long-haul flights. Furthermore, the caffeine intake schedule calculation unit 414 can promote the adjustment of the body clock by setting the timing of caffeine intake to match local time.

[0048] The infectious disease control calculation unit 416 refers to a database that associates travel region information with infectious disease information and countermeasure information. It then compares the referenced travel region information with the destination, accommodation, pre-training camp location, match venue, and travel route, and retrieves infectious disease information and countermeasure information from the database based on the results of the comparison. The data is referenced from information provided by the Ministry of Health, Labour and Welfare, for example. The infectious disease control calculation unit 416 calculates the vaccination date by working backward from the travel period, based on the time required for the vaccine to reach its maximum effect after vaccination, as included in the countermeasure information, and transmits the calculation result to the mobile terminal device 200. It also determines the timing of intake of foods that have a positive effect on immune function (such as lactic acid bacteria) by working backward from the travel period, and transmits the timing of intake to the mobile terminal device 200.

[0049] The infectious disease control calculation unit 416 performs communication processing with a database that associates regional information such as travel destinations, accommodations, pre-training camp locations, and match venues with infectious diseases that may occur in those regions. For example, the reference data used in the database is provided by the Ministry of Health, Labour and Welfare. The infectious disease countermeasure calculation unit 416 obtains location information from the mobile terminal device 200, including the user's travel destination, accommodation, match venue, and travel route including the points between these locations. By comparing this location information with regional information in the database, it predicts the infectious diseases the user may contract. More specifically, the infectious disease countermeasure calculation unit 416 determines whether the user's location information is included in the regional information of the database, and based on that determination, it presents infectious diseases that are prevalent in that region.

[0050] Furthermore, the infectious disease control calculation unit 416 communicates with a prevention information database that associates infectious diseases with preventive measures such as vaccines, in order to output recommended preventive information for predicted infectious diseases. The prevention information database includes, for example, data provided by the Ministry of Health, Labour and Welfare, or data managed by organizations that distribute prevention information. This prevention information database is constructed based on information obtained from public institutions, such as vaccine-related information published by the Ministry of Health, Labour and Welfare.

[0051] The prevention information database includes at least the following: (1) The time it takes for the vaccine to become effective (e.g., effectiveness appears 3 months after vaccination) (2) The recommended timing for vaccination The infectious disease control calculation unit adjusts the timing of vaccination to ensure it is sufficiently effective at the time of travel, based on the planned travel date, match schedule, travel schedule, etc., and transmits information indicating the vaccination timing to the mobile terminal device 200. The infectious disease control calculation unit 416 also handles cases where food (such as lactic acid bacteria) is consumed for the purpose of maintaining or enhancing immune function against infectious diseases in general. For food, rather than associating it with a specific infectious disease, the unit determines the start date of consumption (e.g., consumption starting one month before travel) based on travel and match schedules, and transmits information indicating the determined start date of consumption to the mobile terminal device 200.

[0052] The infectious disease control calculation unit 416 may calculate actions and action schedules for infectious disease control based on location information from the adjustment start date and time to the adjustment end date and time. Infectious disease control includes collecting infectious disease information of the destination and transmitting it to the mobile terminal device 200. In addition, infectious disease control includes receiving vaccinations before travel, checking one's health status and seeing a doctor if necessary, and eating meals containing nutrients that have a positive effect on immune function. Furthermore, infectious disease control includes washing hands and disinfecting hands, wearing a mask, and taking precautions regarding diet, such as regular hydration, while on the aircraft or during travel. The infectious disease control calculation unit 416 may, for example, calculate a schedule for receiving vaccinations or seeing a doctor before travel. The infectious disease control calculation unit 416 may also calculate a schedule for transmitting to the mobile terminal device 200 advice such as wearing a mask on the aircraft or during travel, washing hands and disinfecting hands when going out or eating, or dietary advice to avoid infection.
