摘要：Purpose.This study aimed to assess the validity of the rating of perceived exertion (RPE) session method vs.HR-based methods (Edwards and Banister) for quantifying karate’s training load (TL).Methods.Eleven young karatekas (age 11.34±1.76 years,height 143±6.786 cm,body mass 48.13±7.33 kg,HRmax 205±0.98 bpm) participated in this study.The training sessions was performed on 5 consecutive days with two training sessions for day.During the training Heart Rate was recorded with Cardio “Suunto Memory-Belt” so to calculate the Trimp (Banister) and Training Load (Edwards),while the session-RPE scale is based on the Borg category ratio RPE scale and then modified by Foster et al (CR-10).The validity of RPE method in young Karate athletes,was studied by correlation analysis between RPE session’s training load and both Edwards and Banister’s training impulse score’ method.Results.The HR and RPE were collected from 10 training sessions with inter-day (two sessions for days) correlations were determined (n=11 × 5 days).The mean session-RPE values and correlations in each exercise mode between session-RPE and HR-based TLs (ie,Edwards’s TL and Banister’s TRIMP) showed TL,r = 0.79;95% CI: 0.67 to 0.87 and Banister’s TRIMP,r = 0.63;95% CI: 0.44 to 0.77.Conclusion.The results of the present study provide evidence that the session-RPE method is a simple and inexpensive tool that accurately provides a similar quantification of internal TLs as assessed by the HR-based methods during the various training modes with young karate practitioners.The complex physiological interactions during karate sessions that were dedicated for developing a wide variety of physical capacities makes it difficult for coaches to accurately quantify training load using HR or time measures.Thus,the session-RPE method provides a practical,lowcost,and non invasive tool of quantifying karate training loads,thus making it a valuable tool for athletes,coaches,and sports scientists.
