[0009] Hereinafter, embodiments of the sportswear design tool and sportswear design method according to the present disclosure will be described in detail with reference to the drawings. Note that the present invention is not limited to these embodiments. In the following description, the same parts are designated by the same reference numerals, and duplicated descriptions will be omitted.

[0010] [Sportswear design tool] First, a subject experiment using a sportswear design tool and the distribution of sweat rate will be described with reference to Figures 1 and 2. Hereinafter, the width direction of the body of a person wearing sportswear may be referred to as the left-right direction.

[0011] Figure 1 shows the calculation results of sweat rate in the groin based on actual measured values ​​obtained through experiments. Figure 2 shows the distribution of sweat rate. The distribution of sweat rate in Figure 2 is based on the distribution of sweat rate described in Paper 1 (Smith, CJ, Havenith, G. Body mapping of sweating patterns in male athletes in mild exercise-induced hyperthermia. European Journal of Applied Physiology 111, 1391-1404 (2011)). However, detailed information on the distribution of sweat rate including the groin has not been obtained to date. Therefore, the distribution information of sweat rate including the groin was calculated as follows.

[0012] First, 14 subjects (14 male university students) performed 30 minutes of static standing and 60 minutes of treadmill running (maximum oxygen uptake 60%, incline 1%) while naked. Sweat rate at designated locations on the whole body and whole-body skin surface temperature were measured. Sweat rate was measured using a sweat meter (manufactured by ASE Giken Co., Ltd.). Skin surface temperature was measured using a skin surface temperature probe (manufactured by Nikkiso Thermo Co., Ltd.). The environmental conditions were a temperature of 27.5°C, a relative humidity of 41.7%, and a wind speed of 0 m / s. Measurements included not only skin surface temperature and sweat rate, but also exhaled gases, heart rate, core temperature, heart rate, and subjective assessment. Measurements other than skin surface temperature and sweat rate were used to match the exercise intensity to those in paper 1.

[0013] To calculate the amount of sweating in the groin area in Figure 1, the average of the measured values ​​of sweating in each part of the body (chest, back, lower abdomen, buttocks, and groin) from 30 to 60 minutes after the start of running is calculated. Next, the measured values ​​in Paper 1 are compared to calculate the paper coefficient, which is a coefficient used to convert the measured values ​​of each part of the body other than the groin area to the paper value (upper table in Figure 1). The paper coefficient is calculated by dividing the paper value by the measured value. Next, the average coefficient is calculated, which is the average of the paper coefficients for each part of the body other than the groin area. Next, the measured value of the groin area is multiplied by the average coefficient to calculate the amount of sweating in the groin area 11, as shown in the lower table in Figure 1 and Figure 2. In this way, a running experiment using a nude body can be conducted to calculate the amount of sweating in the groin area 11, which is not disclosed in Paper 1.

[0014] Next, a method for analyzing skin temperature and the distribution of thermal importance in the sportswear design tool will be described with reference to Figures 3 to 5. The skin temperature is the skin surface temperature measured in the above experiment.

[0015] FIG. 3 is a diagram showing the change in skin temperature of the back obtained by an experiment. FIG. 4 is a diagram showing the change in skin temperature of the abdomen obtained by an experiment. FIG. 5 is a diagram in which each part of the body is plotted with the skin temperature when standing still and the change in skin temperature while running as axes. FIG. 6 is a diagram showing the ranking of thermal importance. FIG. 7 is a diagram showing the distribution of thermal importance in FIG. 6. FIG. 8 is a diagram showing the arrangement of the first index, second index, and third index according to an embodiment.

[0016] As the average skin temperature during stationary standing, for example, the average skin temperature from 21 to 30 minutes after the start of stationary standing as shown in Figures 3 and 4 is calculated. Furthermore, as the average skin temperature during running, the average skin temperature from 81 to 90 minutes after the start of stationary standing (51 to 60 minutes after the start of running) is calculated. Furthermore, as the skin temperature change during running, the difference between the maximum and minimum skin temperatures during running is calculated. For example, ΔT, which is the value obtained by subtracting Min from Max shown in Figures 3 and 4, is the difference between the maximum and minimum skin temperatures. Note that ΔT is negative if the minimum skin temperature occurs after reaching the maximum skin temperature, and positive if the maximum skin temperature is reached after reaching the minimum skin temperature.

[0017] For example, the average skin temperature of the back when standing still is calculated to be 32.1°C. The average skin temperature when running is calculated to be 31.9°C. The difference between the maximum and minimum skin temperatures is calculated to be 1.8°C.

[0018] For example, the average abdominal skin temperature in a stationary standing position is calculated to be 34.0°C. The average skin temperature while running is 31.8°C. The difference between the maximum and minimum skin temperatures is calculated to be -2.2°C.

[0019] High skin temperature while standing still indicates a high potential for heat dissipation. Furthermore, a rise in skin temperature while running indicates a high susceptibility to heat stress. Thermal importance is determined from these two perspectives: the potential for heat dissipation and the susceptibility to heat stress. Thermal importance is an index that ranks not only skin temperature while standing still, but also skin temperature while running, and each part of the body is classified into four groups: quadrant 1 21, quadrant 22, quadrant 3 23, and quadrant 4 24, as shown in Figure 5. Quadrant 1 21, quadrant 22, quadrant 3 23, and quadrant 4 24 indicate increasing thermal importance, in that order.

[0020] The threshold value 25 between the first quadrant 21 and the second quadrant 22 and the third quadrant 23 and the fourth quadrant 24 is a value that is a boundary between positive and negative values ​​of Max-Min. For example, if Max-Min is positive, the quadrant is the first quadrant 21 or the second quadrant 22. If Max-Min is negative, the quadrant is the third quadrant 23 or the fourth quadrant 24.

[0021] The thresholds 26 for the first quadrant 21 and the third quadrant 23 and the second quadrant 22 and the fourth quadrant 24 determine values ​​(e.g., 33°C, which is generally considered to be the average skin temperature of an adult) that make it easy to distinguish between upper and lower groups. For example, if the average skin temperature while standing still is higher than 33°C, the quadrant will be the first quadrant 21 or the third quadrant 23. If the average skin temperature while standing still is lower than 33°C, the quadrant will be the second quadrant 22 or the fourth quadrant 24.

[0022] As shown in Figure 6, the first quadrant 21 was grouped as group 21g, the second quadrant 22 as group 22g, the third quadrant 23 as group 23g, and the fourth quadrant 24 as group 24g. The groups were ranked by the average skin temperature from 51 to 60 minutes after the start of the run. This is because higher skin temperatures indicate higher heat dissipation potential. Figure 7 shows a thermal importance distribution 30 based on the ranking in Figure 6. As described above, a thermal importance distribution 30 can be created based on two perspectives: heat dissipation potential and susceptibility to heat stress. Furthermore, because the running experiment was conducted with the naked body, a thermal importance distribution 30 can be created based on more accurate skin temperatures.

[0023] As shown in Fig. 8, by adding (combining) the sweat rate distribution 10 (see Fig. 2) and the thermal importance distribution 30 (see Fig. 7), a first index 1, a second index 2, and a third index 3 that take into account the physiological responses of the human body are arranged on a human body map 40. The arrangement of the first index 1, the second index 2, and the third index 3 will be explained starting from the upper body to the lower body.

[0024] The first index 1, the second index 2, and the third index 3 are indexes that indicate physical importance when taking into account the amount of sweating and skin temperature (thermal importance), with the first index 1 having the highest importance, the second index 2 having a lower importance than the first index, and the third index 3 having a lower importance than the second index 2.

[0025] The first index 1 is located on the upper back 41. The upper back 41 is the most important part for human comfort, as it is highly important in terms of both sweating rate and thermal importance in the central part of the upper back 41 in the left-right direction. The upper back 41 includes the central part of the back and is the area above the central part of the back.

[0026] The third index 3 is placed on the lower back 42. The lower back 42 has a high sweating rate but is not thermally important.

[0027] The first index 1 is placed on the chest 43. The chest 43 is of high importance in the human body map 40 because it is a region of high thermal importance, where the amount of sweating is large in the upper chest, and where discomfort due to fabric sticking to the body is easily felt.

[0028] The third index 3 is placed on the abdomen 44. The abdomen 44 has low thermal importance and many athletes are concerned about cooling the abdomen 44, so it has low importance in the human body map 40.

[0029] The third index 3 is placed on the armpits 45. The armpits 45 are the area with the lowest thermal importance and do not produce much sweat, so they are of low importance in the human body map 40.

[0030] A second index 2 is placed on the arm 46. The importance of the arm 46 is medium both in terms of the amount of sweating and the skin temperature, and therefore the importance of the arm 46 in the human body map 40 is also medium.

[0031] The second index 2 is placed on the shoulder 47. The shoulder 47 has a high thermal importance, but its importance based on the amount of sweating is medium, so its importance in the human body map 40 is also medium.

[0032] The first index 1 is placed on the lumbar region 48. The lumbar region 48 is highly important in terms of both the amount of sweating and thermal importance.

[0033] First index 1 is placed on collar 49. Collar 49 is highly important in terms of both the amount of sweating and thermal importance.

[0034] The second index 2 is placed on both chest regions 50. Both chest regions 50 have medium importance based on the amount of sweating and medium thermal importance, and therefore have medium importance in the human body map 40.

[0035] On the front lower abdomen 51, the first index 1 is placed in the groin area and the third index 3 is placed in the side area. The groin area has a high level of importance in the human body map 40 because of its high skin temperature. The side areas have low importance based on both the amount of sweating and thermal importance.

[0036] The second index 2 is placed on the lower abdomen back surface 52. The buttocks that constitute the lower abdomen back surface 52 are of medium importance in terms of both the amount of sweating and thermal importance.

[0037] The first index 1 is placed on the front foot surface 53. The front foot surface 53 has high importance based on the amount of sweating and thermal importance, and also has high importance in the human body map 40.

[0038] A second index 2 is placed on the dorsal surface of the foot 54. The dorsal surface of the foot 54 has medium importance based on the amount of sweating and medium thermal importance, and therefore has medium importance in the human body map 40.

[0039] Next, a design tool for women's sportswear will be described with reference to FIGS.

[0040] FIG. 9 is a diagram showing the distribution of sweat rates for men and women. FIG. 9(a) is a diagram showing the distribution of sweat rates for women. FIG. 9(b) is a diagram showing the distribution of sweat rates for men. FIG. 10 is a diagram showing a comparison of skin temperatures for men and women. FIG. 11 is a diagram showing the distribution of thermal importance for women. FIG. 12 is a diagram showing the arrangement of the first index, second index, and third index for women according to an embodiment. Note that FIG. 9 is based on the distribution of sweat rates described in Paper 2 (Caroline J. Smith and George Havenith Environmental Ergonomics Research Centre, Loughborough University, UK. "Body Mapping of Sweating Patterns in Athletes: A Sex Comparison"). Also, FIG. 10 is based on the skin temperature comparison data for men and women described in Paper 3 (Body Mapping of Sweating Patterns in Athletes: A Sex Comparison).

[0041] From previous research (e.g., Paper 2), we obtain the distribution of sweating amount 60 for women. As shown in Figure 9, women sweat most in the upper central back 61, the lower central back 62, and the lower chest 63. Meanwhile, women sweat least in the breasts 64 and palms 65.

[0042] Furthermore, as shown in Figure 10, women tend to have lower skin temperatures in the lower body than men. As shown in Figure 11, a distribution 70 of thermal importance is created based on gender differences from the research in Papers 2 and 3.

[0043] As shown in FIG. 12, the first index 1, second index 2, and third index 3 for women are arranged based on the distribution 60 of sweat rate for women (see FIG. 9(a)) and the distribution 70 of thermal importance (see FIG. 11). In this way, by using gender differences in sweat rate and skin temperature, the first index 1, second index 2, and third index 3 for women can be arranged without conducting experiments using women as subjects. The following mainly explains the arrangement of the first index 1, second index 2, and third index 3, focusing on the differences from the arrangement for men.

[0044] The first index 1 is placed on the lower chest 83. The lower chest 83 is a region where women sweat more than men, and therefore has a higher importance in the human body map 80 than men.

[0045] The third index 3 is placed on both chest regions 90. Both chest regions 90 are of medium thermal importance, but have a low importance in the human body map 80 because the amount of sweating is small.

[0046] A second index 2 is placed on the front foot 93. The front foot 93 has lower importance based on the amount of sweating and thermal importance than men, and is therefore of medium importance in the human body map 80.

[0047] Next, the reason for combining the distribution of sweat rate and the distribution of skin temperature (thermal importance) will be described with reference to FIG.

[0048] Fig. 13 is a diagram showing the transition of the heat dissipation amount according to the temperature, based on calculations performed by the applicant using the heat balance equation.

[0049] Humans sweat to prevent skin temperature from rising, but sweating is insufficient during exercise because blood flows preferentially to the muscles. Therefore, it is important to cool areas with high skin temperatures to prevent skin temperature from rising even when sweating is insufficient. Furthermore, as shown in Figure 13, past research has revealed that the rate of heat dissipation due to sweat evaporation increases when the temperature exceeds 15°C (see evaporative heat dissipation in Figure 13). Therefore, it is also important to increase the ventilation rate in areas where sweating is most prevalent to promote sweat evaporation. Based on these findings, the inventors of the present application have developed the layout of the first index 1, second index 2, and third index 3, taking into account both skin temperature and sweat rate.

[0050] 2 and 7, there are regions where sweating is high but thermal importance is low (e.g., the lower central part of the back), and conversely, there are regions where sweating is low but thermal importance is high (e.g., the lower central part of the chest). Therefore, it is insufficient to create the human body map 40, 80 using only one of the sweating rate distribution 10, 60 and the thermal importance distribution 30, 70; it is important to combine the sweating rate distribution 10, 60 and the thermal importance distribution 30, 70.

[0051] [Effects of the embodiment] From the above, by using the sportswear design tool, it is possible to design sportswear with a degree of breathability that corresponds to the importance of the human body maps 40 and 80. As a result, the sportswear design tool can reduce thermal stress in hot and cold environments and improve the comfort of the wearer.

[0052] Furthermore, in a previous study (Jiao Jiao et.al, Effects of body-mapping-designed clothing on heat stress and running performance in a hot environment, Ergonomics.Vol.60(10),1435-1444, 2017), when athletes wore three types of sportswear with different cooling properties during a 1.5km sprint, the results showed that when wearing sportswear that did not take cooling properties into consideration, their time was approximately 8% worse than when wearing sportswear that did. Therefore, it has been shown that sportswear design tools can contribute to improving performance by reducing heat stress.

[0053] [Sportswear design method] Next, a method for designing sportswear will be described with reference to FIGS.

[0054] 14 and 15 are diagrams showing sportswear according to an embodiment. Fig. 15(a) is a diagram showing a vent hole using a shape-retaining material. Fig. 15(b) is a diagram showing an exhaust hole with a double structure.

[0055] As shown in FIG. 14, a fabric having a first air permeability is placed at the location where the first indicator 1 is placed (see FIG. 8). The first air permeability is, for example, 510 m 3 / Hr or more, which is higher than the 22nd and 3rd breathability. More specifically, for example, in the central part 41a of the upper back 41, 3 / Hr fabric is arranged on the outer side 41b of the upper back 41 in the left and right direction, and the air permeability is 948m 3 / Hr fabric is placed in the chest area 43. 3 / Hr fabric is placed, and the lower collar 55 has a breathability of 612m 3 / Hr fabric is placed.

[0056] A fabric having lower breathability than the first breathability is placed at the location where the second index 2 is placed. The second breathability is, for example, 425 m 3 / Hr or more 508m 3 / Hr or less. More specifically, for example, both chest regions 50 are provided with a breathability of 452 m / s. 3 / Hr fabric is placed in the shoulder area 47, and the breathability is 425m 3 / Hr fabric is placed.

[0057] A fabric having lower breathability than the second breathability is placed at the location where the third index 3 is placed. The third breathability is, for example, 340 m 3 / Hr or more 423m 3 / Hr or less. More specifically, for example, the abdomen 44 has an air permeability of 372 m 3 / Hr fabric is placed in the lower back 42, and the breathability is 406m 3 / Hr fabric is placed.

[0058] The air permeability in this embodiment is a value measured by a method in accordance with Japanese Industrial Standards (JIS) L 1096A.

[0059] The fabric for improving breathability is not particularly limited. To send air directly to the critical parts of the human body maps 40, 80, a fabric with a coarse mesh may be placed in the critical parts. For example, a fabric made using a jacquard (a knitting technique) technique may be used as the coarse mesh fabric. Alternatively, a fabric with multiple small through holes may be placed in the critical parts. The diameter of the through holes is, for example, 0.5 mm or more and 1.0 mm or less.

[0060] Alternatively, air may be introduced from the front and sent to the chest 43 and upper back 41. For example, as shown in FIG. 15 , fabric having ventilation holes 100 made of a shape-retaining material may be placed on the shoulders 47, and fabric having dual-layered exhaust holes 101 may be placed on the back, so that air introduced through ventilation holes 100 is exhausted from exhaust holes 101. Here, arrow A indicates the direction of air introduced through ventilation holes 100. Arrow B indicates the direction of air exhausted from exhaust holes 101. Alternatively, fabric made of a mesh material that opens when stretched may be placed on the underarms and back, so that air is introduced from the underarms and exhausted from the back.

[0061] As a method for cooling parts other than the back, fabric with vents 100 made of a shape-retaining material may be placed on the shoulders 47 as described above. Alternatively, highly breathable fabric may be placed on the upper chest area around the collar. Alternatively, mesh fabric or fabric with vents facing forward may be placed on the waist 48 and thighs.

[0062] [Effects of the embodiment] From the above, the sportswear design method can design sportswear with a degree of breathability according to the importance of the human body maps 40 and 80. As a result, the sportswear design method can reduce thermal stress in hot and cold environments and improve the comfort of the wearer.
