The Application of Wingate Anaerobic Test and Physiological-Biochemical Indicators in Monitoring Swimmers' Anaerobic Capacity at Different Time Periods

The purpose of this study is to explore whether there are differences in the improvement of athletes anaerobic capacity with different time arrangements. By conducting the same content of anaerobic training for athletes at different times, the athletes dynamic and physiological and biochemical indicators in the pre-and post-tests were counted, and the athletes indicators were tracked and monitored in the five-week intervention training plan. Using linear regression model and LSTM time series model (Long Short-Term Memory), through statistics and analysis, we find out the differences in training at different times and draw the following conclusions: During the pre and post tests, most of the athletes anaerobic power during the morning test was greater than that during the afternoon test. After five weeks of anaerobic training, the athletes anaerobic power values during the morning and afternoon periods did not increase, and some data values were also lower than those in the previous test, indicating that the athletes anaerobic power is relatively stable, and it is difficult to improve their dynamic changes through short-term special training. Among the indicators reflecting the time to peak power (tPP), the speed of reaching the time to peak power (tPP) in the afternoon is significantly higher than that in the morning, indicating that athletes anaerobic power starts faster in the afternoon. In this article, the changes in heart rate caused by anaerobic training are mainly reflected in the 3-minute and 6-minute test points after morning exercise. The heart rate of athletes in the afternoon is relatively stable and does not produce significant changes. Five weeks of anaerobic training will increase the rate of heart rate decline at the 3-minute and 6-minute test points, indicating that the athletes recovery speed has increased significantly. As the training time increases, the difference between heart rates in the morning and afternoon will gradually decrease, and athletes heart rates tend to approach. After five weeks of anaerobic training, the athletes blood lactic acid values at the immediate and 3-minute test points increased significantly, indicating that the athletes glycolysis and body energy supply capabilities will be improved. Through the 6-minute test point, it can be seen that the athletes acid tolerance and recovery capabilities have also improved. However, the improvement in the above capabilities is mainly reflected in the afternoon and morning responses are not obvious, indicating that athletes ability to glycolysis and acid tolerance is stronger in the afternoon. After training, Athletes glycolysis and acid resistance in the afternoon will be further improved and the improvement will be even greater.
