| dc.description.abstract | INTRODUCTION: To date, no studies have been carried out to compare the effects of cessation of supplementary Isokinetic Training (IT) and Isotonic Training (TON) in strength and biomechanical variables among elite weightlifters. Regarding biomechanical variables of the rotator cuff muscles, most studies were conducted on sedentary population and racket-sports instead of advanced level of weightlifting athletes. OBJECTIVES: This study aimed to compare the cessations effects 1 month after they completed the 24 sessions of isokinetic and isotonic supplementary training among state-level weightlifters on biomechanical variables of rotator cuff muscles. METHODS: Nineteen participants were gender- and weight- matched and randomly assigned into isotonic training group (TON) and isokinetic training (IT) group. Both groups went through 24 sessions of training programmed three times per week for 8 weeks in three distinct lifting positions. The intensity of training was increased progressively in terms of number of lifting repetitions per set and number of sets lifted. After 1 month of the cessation of supplementary training programmed, the athlete when through a follow-up testing. The 2D-kinematic analysis of barbell velocity was evaluated during the second pull and turnover phases of I-RM power clean and power snatch tests. In IT group, the participant was allowed to be seated on the the guidelines instructions. The position of the chair and dynamometer will be set at the particular angle depends on the xvi chair to perform the training programed based on the participant’s comfortability. The participants were asked to perform two sets of 12 repetitions and the angular velocity was set at 120°.s '. Meanwhile in TON group, they using the dumbbell and perform the exercise with maximum effort (as fast as they can). RESULTS: This study revealed that there was no interaction between time (e.g., post- and postl month-tests) and training programmed (e.g., IT versus TON) was found I month after they completed their 24 sessions of supplementary training on biomechanical variables among state-level weightlifters. There was a trend that indicated positive changes in biomechanical variables of IT group compared to TON group in terms of peak torque/body weight, time to peak torque and average power of the external rotation of the shoulder joint. However, the TON training was better compared to IT training after the cessation effects in 1RM (repetition maximum) power snatch and power clean, and also in kinematic analysis during 1RM test. CONCLUSION: The isokinetic training program has a potential to be proposed as an additional mode of training among the experienced weightlifters to improve their performance. | |
