Description

Technical Field

[0001] This invention relates to the field of running performance prediction technology, specifically to a method for predicting middle- and long-distance running performance based on sprint speed and anaerobic threshold speed. Background Technology

[0002] When testing or competing in middle- and long-distance running events, being able to predict one's performance allows for better tactical planning and energy management. Furthermore, it provides insights into the percentage of intensity one's current pace corresponds to in different distances during training. While sprint performance doesn't require prediction and can be obtained through a few runs, middle- and long-distance running involves numerous events and repeated testing, requiring significant physical exertion, which is difficult for most people to manage. Therefore, a relatively simple, energy-efficient, and accurate method for predicting middle- and long-distance running performance would benefit not only athletes' competition training but also students preparing for physical education exams, military personnel, and running enthusiasts in improving their performance and training.

[0003] Currently, there are few methods for predicting middle- and long-distance running performances, and the prediction events are limited to specific events. These methods are generally physically demanding and complex. Therefore, there is a need to design a relatively simple, less physically demanding, and accurate method for predicting middle- and long-distance running performances to meet the needs of different groups of people. Summary of the Invention

[0004] The purpose of this invention is to predict middle- and long-distance running performance based on sprint speed and anaerobic threshold speed. It is simple to operate, consumes little physical energy, and provides accurate predictions. It is also applicable to the prediction needs of different groups of people and different middle- and long-distance running events.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A method for predicting middle- and long-distance running performance based on sprint speed and anaerobic threshold speed includes the following steps:

[0007] S1. Test the average speed of a 200m run;

[0008] S2, Test the anaerobic threshold velocity;

[0009] S3. Calculate the ratio of the average speed of middle-distance running to the average speed of 200m running based on the average speed of 200m running and the anaerobic threshold speed.

[0010] S4. Calculate the average speed of the middle-distance run based on the ratio of the average speed of the 200m run to the average speed of the middle-distance run.

[0011] S5. Divide the running distance of a middle-distance run by the average speed of the middle-distance run to obtain the completion time of the middle-distance run.

[0012] Furthermore, in S1, the average speed of the 200m run is tested using both direct testing and indirect calculation methods.

[0013] The direct testing method includes: running 200m on a standard track and obtaining the average speed of the 200m run; the indirect calculation method includes: running 50m on a standard track and obtaining the average speed of the 50m run, then calculating the average speed of the 200m run from the average speed of the 50m run, using the following formula: V 200 =V 50 ×1.1 or V 200 =V 50* V 200 V is the average speed of a 200m run. 50 For predicting middle- and long-distance running performance, the runners are compared to the average 50-meter running speed of professional 100m or 200m runners, V. 50* The runners used to predict middle- and long-distance running performance are non-professional 100m or 200m runners and their average 50m running speed.

[0014] Furthermore, in S2, the anaerobic threshold velocity test includes two methods: direct testing and indirect calculation.

[0015] The direct testing method includes: S a1 Running on a treadmill, the starting speed is set at 6-10 km / h, then the speed is increased linearly by 1 km / h per minute until the respiratory quotient is ≥1.05; a2 S was calculated using the V-slope method. a1 The anaerobic threshold speed of the treadmill; S a3 The anaerobic threshold velocity is calculated based on the anaerobic threshold velocity of the treadmill. The calculation formula is as follows: V = V A V A =V B ×0.96, V is the anaerobic threshold velocity, V A V is the outdoor anaerobic threshold velocity. B This refers to the anaerobic threshold speed of the treadmill.

[0016] The indirect calculation method includes: S b1 Calculate the rate of maximum oxygen uptake; S b2 Calculate the proportion of slow-twitch muscle fibers; S b3 The anaerobic threshold velocity is calculated based on the VO2 max velocity and the proportion of slow-twitch muscle fibers. The calculation formula is as follows: V = (0.3333 × R) sm +0.5833)×R oumax V is the anaerobic threshold velocity, R sm For the proportion of slow-twitch muscle fibers, R oumax The rate of maximum oxygen uptake.

[0017] Furthermore, the S b1 Including: S b11 Construct a linear equation for the relationship between running heart rate and running speed: Y = aX + b, where X represents running heart rate and Y represents running speed. b12 Run on a treadmill and measure the heart rate at at least two running speeds above 7 km / h. Substitute the running speed and the measured heart rate as Y and X, respectively, into the linear equation Y = aX + b, calculate a1 and b1, and obtain Y = a1X + b1; b13 Calculate the maximum heart rate, substitute the maximum heart rate as X1 into the linear equation Y = a1X + b1, and calculate the running speed Y1, where the running speed Y1 is the speed of maximum oxygen uptake.

[0018] Furthermore, the S b13 In this context, the formula for calculating maximum heart rate is as follows: R Hmax =220 - Age, R Hmax Maximum heart rate; Age is age in years.

[0019] Furthermore, the S b2 The formula for calculating the proportion of slow-twitch muscle fibers is as follows: R sm =1.6 - 25128 ÷ t 50 ÷(R oumax ×147.6+661.5), t 50 The time to complete a 50m run is given in seconds. The time to complete a 50m run is obtained by running 50m on a standard track.

[0020] Furthermore, in S3, the formula for calculating the ratio of the average speed of middle-distance running to the average speed of 200m running is as follows: Y = K × S n K is the ratio of the average speed when running 1m to the average speed when running 200m, S is the running distance of middle-distance running, and n is the decrease in average speed when the running distance is doubled. n It represents the ratio of the average speed in middle-distance running to the average speed when the running distance is 1m.

[0021] Furthermore, the formula for calculating the decrease in average speed *n* for each doubling of the running distance is as follows: *n* = log0 a b, where a is the ratio of anaerobic threshold speed to the average speed of a 200m run, and b is the ratio of the marathon running distance to the 200m running distance.

[0022] Furthermore, the formula for calculating the ratio K of the average speed when running a distance of 1m to the average speed when running 200m is as follows: K = 100% ÷ 200n 100% means setting the average speed when running a distance of 1m to 100%, 200 n It represents the ratio of the average speed in a 200m run to the average speed when the running distance is 1m.

[0023] Furthermore, in S4, the formula for calculating the average speed of middle- and long-distance running is as follows: V S =V 200 ×Y, V S This represents the average speed in middle- and long-distance running.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This invention predicts middle- and long-distance running performance based on sprint speed and anaerobic threshold speed. Sprint speed (average speed in a 200m run) and anaerobic threshold speed (equivalent to marathon running speed) can be obtained through testing. The ratio of the average speed in the middle- and long-distance run to the average speed in the 200m run is calculated based on these two values. Then, the average speed in the middle- and long-distance run is calculated using the ratio of the average speed in the 200m run to the average speed in the middle- and long-distance run. Finally, the completion time, i.e., the middle- and long-distance running performance, is obtained by dividing the running distance by the average speed. This invention is simple to operate, requires minimal physical exertion, and provides accurate predictions, making it suitable for different groups of people and for different middle- and long-distance running needs. Attached Figure Description

[0026] Figure 1 This is a flowchart of the method of the present invention. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] Studies have shown that as running speed increases, the distance a human can complete decreases. This is mainly due to increased air resistance, insufficient energy supply rate, and an increase in fatigue-inducing substances associated with higher running speeds. Statistical analysis of running speed changes among different runners over different distances reveals that, except for the 50m and 100m races, the average speed in other running events decreases proportionally with increasing distance (the 50m and 100m races do not exhibit this pattern, primarily because the acceleration phase at the start significantly impacts average speed in these events. For races longer than 200m, the impact of acceleration at the start is smaller). Therefore, the average speed changes with distance. Furthermore, the rate of speed decline varies among runners. The rate of speed decline can be obtained by testing the average speed of sprints (200m) and long-distance runs (marathon), and then the average speed for the desired middle-distance or long-distance run can be derived from the average speed and rate of speed decline in the sprint (200m). Regarding the average speed in a marathon, it is difficult for runners to reach their personal best speed due to the influence of many factors such as weather, slope, energy distribution, and energy replenishment. Studies show that the anaerobic threshold speed is very close to the average speed of a marathon run under ideal conditions, so the anaerobic threshold speed can be used as an equivalent to the average speed in a marathon.

[0029] like Figure 1 As shown, the present invention provides a method for predicting middle- and long-distance running performance based on sprint speed and anaerobic threshold speed, comprising the following steps:

[0030] S1. Test the average speed of a 200m run;

[0031] S2, Test the anaerobic threshold velocity;

[0032] S3. Calculate the ratio of the average speed of middle-distance running to the average speed of 200m running based on the average speed of 200m running and the anaerobic threshold speed.

[0033] S4. Calculate the average speed of the middle-distance run based on the ratio of the average speed of the 200m run to the average speed of the middle-distance run.

[0034] S5. Divide the running distance of a middle-distance run by the average speed of the middle-distance run to obtain the completion time of the middle-distance run.

[0035] This invention predicts middle- and long-distance running performance based on sprint speed and anaerobic threshold speed. Each individual's sprint speed (average speed in a 200m run) and anaerobic threshold speed (equivalent to marathon speed) can be obtained through testing. The ratio of the average middle- and long-distance running speed to the average 200m running speed is then calculated based on these two values. Finally, the average middle- and long-distance running speed is calculated using the ratio of the average 200m running speed to the average middle- and long-distance running speed. This invention is simple to operate, requires minimal physical exertion, and provides accurate predictions, making it suitable for different groups of people and for various middle- and long-distance running prediction needs.

[0036] In some instances, the average speed test for the 200m run in S1 includes two methods: direct testing and indirect estimation. Direct testing is conducted on a standard track (standard field), suitable for athletes and healthy young people who run regularly. The direct testing method involves running 200m on a standard track and obtaining the average speed. However, for inexperienced runners, the 200m run is not only physically demanding, but performance is also affected by factors such as physical exertion and willpower, sometimes preventing them from performing at their best. The 50m run, on the other hand, is shorter and less demanding, and is a physical education exam item in middle school and even university; therefore, even ordinary people can perform at their true level. Comparing the 50m and 200m runs, because the acceleration phase is larger in the 50m and smaller in the 200m, the average speed of a professional sprinter (professional 100m or 200m runner) in the 50m run will be lower than their average speed in the 200m run. Statistical analysis of the average speeds of professional sprinters in the 50m and 200m runs reveals a correlation between the two. The indirect calculation method includes: running 50m on a standard track to obtain the average speed of the 50m run, and then calculating the average speed of the 200m run from the average speed of the 50m run. The calculation formula is as follows: V 200 =V 50 ×1.1 or V 200 =V 50* V 200 V is the average speed of a 200m run. 50 For predicting middle- and long-distance running performance, the runners are compared to the average 50-meter running speed of professional 100m or 200m runners, V. 50* The runners used to predict middle- and long-distance running performance are non-professional 100m or 200m runners and their average 50m running speed.

[0037] In some instances, the anaerobic threshold velocity test in S2 includes both direct testing and indirect estimation methods. The direct testing method includes: S a1Running on a treadmill, after a thorough warm-up, is recommended. The starting speed should be 6-10 km / h, with the specific speed depending on the individual's ability. The speed should then be increased linearly by 1 km / h per minute until the respiratory quotient (RQ) is ≥1.05. The RQ test is a current method and will not be elaborated upon. a2 S was calculated using the V-slope method. a1 The anaerobic threshold speed on the treadmill, specifically the V-slope method for testing anaerobic threshold speed, is an existing method and will not be elaborated upon; S a3 The anaerobic threshold velocity is calculated based on the anaerobic threshold velocity of the treadmill. The calculation formula is as follows: V = V A V A =V B ×0.96, V is the anaerobic threshold velocity, V A V is the outdoor anaerobic threshold velocity. B This refers to the anaerobic threshold speed on a treadmill. Since a marathon is an outdoor event with air resistance (which accounts for 4% of speed), and treadmill running does not generate air resistance, the outdoor anaerobic threshold speed is 96% of the treadmill anaerobic threshold speed. This outdoor anaerobic threshold speed is the same as the aforementioned anaerobic threshold speed. The treadmill used for direct testing must be equipped with a respiratory quotient (HRQ) testing device, and the anaerobic threshold speed must be determined by at least two experienced professionals.

[0038] Extensive testing and statistical analysis have shown a correlation between anaerobic threshold speed, VO2 max speed, and the ratio of fast-twitch muscle fibers to slow-twitch fibers. Therefore, anaerobic threshold speed can be estimated by testing VO2 max speed and the ratio of fast-twitch muscle fibers to slow-twitch fibers. The indirect estimation method includes: S b1 Calculate the rate of maximum oxygen uptake; S b2 Calculate the proportion of slow-twitch muscle fibers; S b3 The anaerobic threshold velocity is calculated based on the VO2 max velocity and the proportion of slow-twitch muscle fibers. The calculation formula is as follows: V = (0.3333 × R) sm +0.5833)×R oumax V is the anaerobic threshold velocity, R sm For the proportion of slow-twitch muscle fibers, R oumax The rate of maximum oxygen uptake.

[0039] VO2 max speed refers to the critical intensity at which maximum oxygen uptake or maximum heart rate is just reached during progressively increasing speed exercise, starting from a low speed. VO2 max speed can be directly measured by running to exhaustion at an increasing speed, but this direct test is very demanding and carries significant risk of injury. VO2 max speed can also be obtained indirectly. Because there is a very significant positive correlation between the increase in running speed and the increase in heart rate when the heart rate exceeds 110 beats per minute during aerobic exercise, the speed at which maximum heart rate is just reached can be estimated through a two-level or higher load test exceeding 110 beats per minute, and this speed is defined as VO2 max speed (Note: Oxygen ingested during exercise is transported through blood circulation; therefore, when the heart rate reaches its maximum, the blood circulation volume reaches its maximum, and the oxygen uptake also reaches its maximum).

[0040] The preferred indirect calculation method of this invention includes S b11 Construct a linear equation for the relationship between running heart rate and running speed: Y = aX + b, where X represents running heart rate and Y represents running speed. b12 Run on a treadmill and measure the heart rate at at least two running speeds above 7 km / h. Substitute the running speed and the measured heart rate as Y and X, respectively, into the linear equation Y = aX + b, calculate a1 and b1, and obtain Y = a1X + b1; b13 Calculate the maximum heart rate, substitute the maximum heart rate as X1 into the linear equation Y = a1X + b1, and calculate the running speed Y1, where the running speed Y1 is the speed of maximum oxygen uptake.

[0041] Furthermore, the S b13 In this context, the formula for calculating maximum heart rate is as follows: R Hmax =220 - Age, R Hmax Maximum heart rate; Age is age in years.

[0042] The following is a specific example of indirect estimation of VO2 max speed, specifically for a 40-year-old runner. It includes: S b11 Construct a linear equation for the relationship between running heart rate and running speed: Y = aX + b, where X represents running heart rate and Y represents running speed. b12 The runner ran on a treadmill, and the heart rates at three running speeds of 10km / h, 11km / h, and 12km / h were measured to be 120 beats / minute, 130 beats / minute, and 140 beats / minute, respectively. Substituting these running speeds and measured heart rates as Y and X, respectively, into the linear equation Y = aX + b, we calculate a = 0.0667 and b = 2, obtaining Y = 0.0667X + 2; b13 Substitute the runner's age of 40 into the formula for calculating maximum heart rate R.H max =220-Age, the maximum heart rate is 180 beats / minute. Substituting the maximum heart rate of 180 beats / minute into the linear equation Y = 0.0667X + 2, the runner's maximum oxygen uptake speed is 14km / h.

[0043] Human movement is achieved through the contraction of skeletal muscles. Skeletal muscles can be broadly divided into fast-twitch and slow-twitch muscles. Fast-twitch muscles have strong explosive power but poor endurance and are easily fatigued, playing a greater role in short-distance running. Slow-twitch muscles, on the other hand, have poor explosive power but strong endurance, playing a greater role in long-distance running. The ratio and function of fast and slow-twitch muscles in humans are influenced by genetic and training factors. A higher proportion of fast-twitch muscles at birth gives an advantage in sprinting, while a higher proportion of slow-twitch muscles at birth gives an advantage in long-distance running, and the ratio of fast and slow-twitch muscles rarely changes after birth. Based on the ratio of fast and slow-twitch muscles, people with a higher proportion of fast-twitch muscles and strong explosive power are generally called "speed type," those with a higher proportion of slow-twitch muscles and strong endurance are called "endurance type," and those in between are called "intermediate type." The ratio of fast and slow-twitch muscles has a certain impact on running distances.

[0044] While the ratio of fast-twitch and slow-twitch muscle fibers can be obtained through muscle biopsy, this procedure is akin to minor surgery and can cause some damage to the body. Therefore, it is difficult to achieve from both an ethical and technical standpoint. However, the ratio of slow-twitch muscle fibers can be obtained using the completion time of a 50m sprint and the speed of maximum oxygen uptake, calculated using the following formula: R sm =1.6 - 25128 ÷ t 50 ÷(R oumax ×147.6+661.5), t 50 The time to complete a 50m run is given in seconds. The time to complete a 50m run is obtained by running 50m on a standard track.

[0045] This invention is applicable to predicting the completion time of running distances ranging from 200m to a marathon (42.195 km). In some embodiments, in step S3, the formula for calculating the ratio of the average speed of middle-distance running to the average speed of 200m running is as follows: Y = K × S n K is the ratio of the average speed when running 1m to the average speed when running 200m (since the average speed when running 1m is only a theoretical value without considering factors such as the start), S is the running distance of middle-distance running, and n is the decrease in average speed when the running distance is doubled. n It represents the ratio of the average speed in middle-distance running to the average speed when the running distance is 1m.

[0046] Furthermore, the formula for calculating the decrease in average speed *n* for each doubling of the running distance is as follows: *n* = log0 a b, where a is the ratio of anaerobic threshold speed to the average speed in a 200m run; specifically, a = V A ÷V 200 Let b be the ratio of the marathon running distance to the 200m running distance. Specifically, b = 42.195 × 1000 ÷ 200 = 210.975. For different runners, the decrease in average speed (n) when the running distance doubles varies.

[0047] Furthermore, the formula for calculating the ratio K of the average speed when running a distance of 1m to the average speed when running 200m is as follows: Different runners = 100% ÷ 200 n 100% means setting the average speed when running a distance of 1m to 100%, 200 n This represents the ratio of the average speed in a 200m run to the theoretical fastest speed when the running distance is 1m, where n is the decrease in average speed for every doubling of the running distance. Similarly, the ratio K of the average speed in a 1m run to the average speed in a 200m run will be different for different runners.

[0048] Therefore, by using K and n for different runners, the ratio of the average speed of different runners and the average speed of 200m running can be calculated.

[0049] In some embodiments, the formula for calculating the average speed of middle-distance running in step S4 is as follows: V S =V 200 ×Y, V S This represents the average speed in middle- and long-distance running. Therefore, based on different runners and different running distances in different middle- and long-distance runs, we can obtain the average speed of different runners in different middle- and long-distance runs.

[0050] By calculating the average speed of different middle- and long-distance runs for different runners, and then dividing the running distance of the middle- and long-distance run (the running distance to be predicted is known) by the average speed of the middle- and long-distance run, the completion time of the middle- and long-distance run can be obtained, thus enabling the prediction of different runners' performance in different middle- and long-distance runs.

[0051] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present invention used to illustrate the technical solutions of the present invention, and are not intended to limit the invention, nor are they intended to limit the patent scope of the present invention.
