Abstract
The present study investigated the effect of intense and tapering training periods using different exercise modalities (i.e., Randori – grip dispute practice without throwing technique, Uchi-komi – technique repetition training, and sprinting) on rating of perceived exertion (RPE), well-being indices, recovery state, and physical enjoyment in judo athletes. Sixty-one adolescent male and female judo athletes (age: 15 ± 1 years) were randomly assigned to one of three experimental or one control groups. Experimental groups (Randori, Uchi-komi, and running) trained four times per week for 4 weeks of intense training (in addition to their usual technical-tactical judo training; control group underwent only such a training) followed by 12 days of tapering. RPE, well-being indices [i.e., sleep, stress, fatigue, and delayed onset muscle soreness (DOMS)], total quality of recovery (TQR), and physical enjoyment were measured every session. RPE, sleep, stress, fatigue, DOMS, Hooper index (HI; sum of wellbeing indices), and TQR were lower in the tapering compared with the intensified training period (P < 0.001). Moreover, the running group showed better values for sleep (P < 0.001), stress (P < 0.001), fatigue (P = 0.006), DOMS (P < 0.001), and HI (P < 0.001) in comparison with the other training groups, indicating a more negative state of wellbeing. The Randori and Uchi-komi groups showed higher values for TQR and physical enjoyment (both P < 0.001) than the running group, whereas RPE was lower in the control compared with all training groups (P < 0.001). Coaches should use more specific training modalities (i.e., Randori and Uchi-komi) during intensified training and should monitor well-being indices, RPE, and TQR during training periods. Moreover, for all variables, 12 days tapering period are beneficial for improving wellbeing and recovery after 4 weeks of intense training.
Highlights
Judo is a dynamic grappling combat sport characterized by high-intensity intermittent actions, requiring complex skills and tactical excellence for success (Franchini et al, 2011)
Rating of perceived exertion differed between groups (F3,1254 = 31.354 and P < 0.001, Table 1), with lower values for control compared with Randori (P < 0.001), Uchi-komi (P < 0.001), and running (P < 0.001)2
The present study showed that total quality of recovery (TQR) scores during the intense training period were lower than those measured during tapering, indicating that recovery status is positively related to training volume and frequency reduction
Summary
Judo is a dynamic grappling combat sport characterized by high-intensity intermittent actions, requiring complex skills and tactical excellence for success (Franchini et al, 2011). Many studies have been conducted to examine the effect of different training modes to enhance physiological aspects that are directly related to success in judo competition (Papacosta et al, 2013; Franchini et al, 2016a,b; Ouergui et al, 2019). Among these modalities, high-intensity intermittent training (HIIT) has emerged as a training regimen commonly used for judoka athletes. It was reported that intensified training (i.e., increased training loads) is related to psychometric status in athletes, which can be influenced by workload, fatigue accumulation, imbalance between training and recovery, and training modality (Selmi et al, 2018b)
