Kaabi, S, Mabrouk, RH, and Passelergue, P. Weightlifting is better than plyometric training to improve strength, counter movement jump, and change of direction skills in Tunisian elite male junior table tennis players. J Strength Cond Res 36(10): 2912-2919, 2022-This study aimed to compare the effect of integrating weightlifting (WL) resistance training or plyometric training for 8 weeks on physical performance among elite male junior table tennis players. Forty-five players were randomly divided into 3 groups. A WL resistance training group (n 5 15), plyometric (P) group (n 5 15), and a control (C) group (n 5 15). Weightlifting group and P group were trained for 8 weeks (2 sessions per week with 3 different exercises each time) in addition to the usual practice of table tennis during the preparatory phase, whereas the C group continued classical table tennis training sessions. Subjects were tested for 5-m sprint time, change of direction (CD) test on a 20-m "T" shape course, jumping tests such as standing long jump, squat jump (SJ) and countermovement jump, hang grip, and 1 repetition maximum strength tests as the bench press and back squat before (T0) and after (T1) the training program. There was no statistical difference between the 3 groups before the beginning of the training program. After the 8-week training program, only P and WL groups significantly improved their performances for all the tests. Combining all the tests, the WL group had larger improvement (12.6 vs. 8.2%) and effect sizes (1.88 vs. 1.22) than the P group. Thus, WL training seems more efficient than P training to improve neuromuscular performance of table tennis players, especially for a sport-specific table tennis change-of-direction test such as the 20-m CD test.

Our study consists of identifying the relationships between emotional intelligence, in terms of emotional profile, and Tunisian and foreign karatekas, verifying their impact on the coaching effectiveness of coaches as well as that of the social context and material conditions and supervision on the performance of Tunisian and foreign karatekas. To verify our hypotheses, we administered the questionnaire "Profile of emotional skills" to 200 Tunisian and foreign athletes. Statistical analyzes showed a significant difference between Tunisian elite karatekas and foreign elite karatekas (p < 0.0001) in terms of emotional skills profile.
