ABSTRACT This paper examines the effects of plyometric and resistance training on the explosive power and the amount of young male volleyball players’ strength in Guilan province.
We found that after a six weeks training, there were significant differences between the average of explosive power and strength in both groups of plyometric and resistance training in comparison to control group (P≤0.
The researcher observed that there was a significant difference in the average of explosive power and strength within both plyometric and weight groups from pre to post-test (p≤0.
Since weight training at this age necessitates special care and attention, and there are very few researches in this regard, this paper examines the effects of plyometric and resistance trainings with weight on explosive power of young Guilan province volleyball players.
DISCUSSION It was evident that after six weeks plyometric and resistance training, young volleyball players have had great improvement in their skeletal strength and explosive power.
Perhaps the increase in explosive power after plyometric trainings in this study, was due to neural adaptations such as: preparation of more biomotor ability, excitation of motor units with more frequency, selective utilization of motor units in adapted muscles, concurrent constriction of some muscles, the change in the speed of external and internal constriction phase and the increase in skeletal resistance and strength."
