Title: The effectiveness of improving the spike velocity of amateur male volleyball players by strengthening their upper body

Abstract:

Purposes: This study compared the effectiveness of improving spike velocity of amateur male volleyball players by strength training and power training. Spike velocity is the most significant indicator of volleyball spike. In the amateur volleyball competition, spike velocity is the determining factor of the match outcome because greater spike velocity results in less time for defenders to dig the ball. Improvement of upper body strength might improve spike velocity. Methodology: Eleven amateur male volleyball players took part in a 4-weeks strength training study in conjunction with their volleyball training. They were allocated to two groups: strength training group and power training group as these are the major training method to improve the strength of volleyball players. Strength training was invited to the gym to have weight training including bench press, bent over row, overhead press and lateral pull- down. The power training group used a 3kg medicine ball to have training including squat slam, rotational slam, single-arm throw and overhead throw. Pre and post- training measurements of spike velocity were recorded. Results: Significant difference in improvement of spike velocity among the strength training group and the power training group was found. A decline of spike velocity was found in the strength training group while an increase of spike velocity was found in the power training group. Conclusion: In conclusion, power training was found to be a more effective way for improvement of spike velocity but further research is needed.
