| Purpose: The improvement of sports performance comes from the balance between training load and recovery,and the monitoring of training load is a necessary prerequisite for mastering the balance between training load and recovery.The success of any training program depends on its ability to induce specific physiological adaptations in the athlete and to translate these physiological adaptations into improved athletic performance.Central to this process is the ability to control the adaptive response through the monitoring of training loads,to deal with accumulated fatigue and to take advantage of the after-effects of various training factors.Therefore,the monitoring of training load is crucial for athletes.In some sports teams,the quantification of training load is difficult to be carried out due to the lack of equipment and scientific personnel.In the daily coaching work,coaches usually rely on their own subjective feelings and coaching experience to quantify the training load.However,the method of developing training programs through subjective measurements may not be accurate.In this context,the session-RPE has been increasingly welcomed by coaches and athletes as a simple,effective and inexpensive method to quantify the training load of athletes,but its validity for application to the short track speed skating athlete population deserves further study.Therefore,the purpose of this paper is to investigate the arrangement and variation characteristics of training loads of short track speed skaters quantified using session-RPE and to analyze the relationship between session-RPE and other variables,so as to investigate the effectiveness of session-RPE in quantifying training loads of athletes in short track speed skating.Methods: In this study,nine members of the Shanghai short track speed skating team were used as the study subjects.The training load of each training session of the 9athletes was quantified using session-RPE,with variables including daily and weekly training load as well as training monotonicity and training stress values;the athletes’ daily morning pulse values were recorded,and the athletes’ daily recovery was recorded by means of a questionnaire,with variables including Hooper index,muscle soreness score,sleep quality score,and fatigue score;the training was monitored using the Firstbeat heart rate system was used to monitor the training of six athletes,with variables including three heart rate based training strokes,energy expenditure,mean heart rate and mean respiratory rate.In addition,four athletes underwent two blood tests.The data were collected and organized by Excel.Using SPSS 26.0,the differences in training loads of different types of training sessions and the changes in blood indicators were analyzed using paired samples t-test;the differences in training loads of athletes of different genders were analyzed using independent samples t-test;the training loads quantified by session-RPE were analyzed with each variable using Pearson correlation analysis;and Origin Pro2018 for plotting.Results:(1)The training loads of short track speed skaters in the pre-competition period were consistent with the scientific mid-cycle module load arrangement,and there was a significant difference between ice training and land training loads(P<0.01),and there was no significant difference between the training loads of athletes of different genders(P>0.05).(2)The correlation between training load quantified using the session-RPE method and some recovery variables was statistically significant(P<0.05);(3)The correlation between training load quantified using the session-RPE method and some indicators monitored by the Firstbeat heart rate system was statistically significant(P<0.05);(4)The correlation between training load quantified using session-RPE method and training load quantified based on heart rate was statistically significant(P<0.05)Conclusion:(1)The training loads of short track speed skaters quantified using sRPE are consistent with the scientific mid-cycle modular load alignment and the differential characteristics of training loads on ice and on land for short track speed skating events.(2)There was some agreement between training load quantified using session-RPE and recovery variables such as morning pulse,Hooper index and blood indicators as well as training load and energy expenditure calculated based on heart rate in short track speed skaters.(3)The session-RPE can be used as a simple and practical method to quantify the training load of short track speed skaters. |
