摘要

Purpose: The aim of this study was to investigate the effects of strength performance on lower extremities and muscle energy metabolism in rugby players following two weeks training using the passive repeated isokinetic machine (PRI). Method: Ten male rugby players (15.3±1.06 yrs, height=172.4±4.9 cm and mass=74.7±14.4 Kg) were recruited for this study. During a 2-week investigation PRI training was performed before rugby training. The PRI training protocol consisted of 3x2x30s (60-70 RPM) four times per week. A pre test was performed to determine baselines; following 2 weeks PRI training post tests were performed. Testing parameters included CMJ and muscle energy metabolism blood lactate and NH3. Results: CMJ results indicated no significance (p＞.05) between pre and post test. NH3 results indicated significance -15.00 μmol/l (p＞.05) between pre and post test. Also blood lactate results indicated significance +0.65mmol/l (p＞.05) between pre and post test. Conclusion: From this investigation results indicated that CMJ performance did not improve after two weeks of training with the PRI training machine. This phenomenon was possibly related to the short duration period the muscles had to adapt to the training protocol. However, energy metabolism results were positively affected in relation to protein and carbohydrate turnover.
