| Objective : Due to its time-saving and efficient characteristics,high-intensity interval training has always been an important training method to improve anaerobic ability.However,there are many variables,complex combinations,and less research on specific collocation schemes.In the training of power cars,different riding times and the ratio of cycling and intermittent time will have an impact on the training effect.Therefore,this paper compares the six different HIIT by observing and analyzing the changes of anaerobic peak power,average anaerobic power and anaerobic power decreasing rate obtained from the anaerobic test before,middle and after HIIT intervention for four weeks,as well as the changes of subjects’ lower limb electro mytroelectricity,muscle oxygenation,heart rate and blood lactic acid.The impact of the HIIT scheme on the anaerobic ability of subjects ultimately provides theoretical and data reference for coaches to choose the best HIIT solution to improve anaerobic ability.Methods: This study adopts the literature method to consult the literature materials in relevant fields to provide theoretical support for the determination of the style scheme of this article.Adopt the experimental method,30 male college students with a certain training foundation were selected as experimental subjects.Using random groups,it is divided into six experimental control groups [working time(s): intermittent recovery time(s)= A(15:60);B(15: 90);C(15: SS);D(30: 120);E(30: 180);F(30: SS)].Carry out a four-week HIIT intervention,and conduct a 30 s Wingate test before,two weeks after the intervention,and record the heart rate,lower biceps,lateral femoral muscle,medial femoral muscle,rectus rectus muscle,lateral gastrocnemius muscle,tibial anterior tibial muscle surface myoelectric Muscle oxygen,peak blood lactic acid.Using mathematical statistics,because there is no significant difference between the six groups of indicators in the previous test,all the data of this experiment are expressed in average ± standard deviation,and the experimental data are statistically analysed by SPSS27.0 software.The pre-intervention,during and post-intervention heart rate,blood lactic acid,30 s power cycling peak power,average power,anaerobic power decreasing rate,efics,and musoxia data of the six groups of this experiment were analyzed using paired T tests to observe the differences before,during and after intervention in the group.Two-factor repeated measurement variance analysis(group × number of measurements)was carried out on the peak power,average power,anaerobic power reduction rate,myoelectricity and muscle oxygenation data before,middle and after the training intervention between the six groups of groups,and judged the interaction between different groups and the interaction of different measurements and the main The effect.Results:1.The interaction of average anaerobic power and anaerobic peak power in the interaction between the pre-test,middle and post-groups and the number of measurements during training intervention,and the main effect of the group are not significant(p>0.05).The main effect of the number of measurements

power effect is the best;30s cycling working time with 2min intermittent recovery time to improve the anaerobic peak power effect is the best;30s cycling working time with 3min intermittent recovery time to improve the anaerobic power reduction rate effect The best.Coaches can choose according to different training purposes.2.Six kinds of HIIT interventions can lead to the improvement of the biceps of the lower biceps,lateral femoral muscle,medial femoral muscle,rectus muscle,lateral gastrocnemius muscle surface RMS,lateral femoral muscle,lateral gastrocnemius muscle,and anterior tibial muscle MDF.30 s cycling working time with 2min intermittent recovery time is the best improvement effect.3.Six HIIT four-week interventions failed to improve heart rate and muscle oxygen saturation.Six HIIT interventions can reduce peak blood lactic acid,.15 s cycling working time with 3min intermittent recovery time is the best effect.4.The HIIT scheme,which is matched with different riding times and recovery times,shows different advantages to the riding power of the 30 s power car,the myoelectricity on the surface of the lower limb muscle and the peak blood lactic acid.The coach can choose the plan according to different training purposes. |
