Discussion on College Gymnastics Training Mode Based on Decrement Model
Parameter estimation and prediction ability analysis of four mathematical models of reduced training load-physical state were carried out to investigate the effects of each training mode on physical state and physical state.The models of overload exponential decrement,overload linear decrement,exponential decrement and linear decrement were constructed by calculating the data of athletes'recovery heart rate after training and using load center of grav-ity level and optimal parameters of heart rate recovery correction.The simulation software MATLAB simulink was used to estimate the model parameters and analyze the prediction ability.The results showed that there were statistical differences in the time to reach the maximum physical state of the four measures of exercise reduction(P＜0.01).Compared with the overload linear decrement,exponential decrement and linear decrement training,the overload exponential decrement training has the shortest time to reach the maximum load and the fastest recovery of physical condition.The fitting degree of each model to the training data is more than 0.89,and the correlation between the predicted value and the actual value is more than 0.95.Overload exponential reduction training is more beneficial to athletes'physi-cal fitness recovery.This model is suitable for the prediction of physical fitness state.
