Abstract
Introduction: There is disagreement about transmitting the effects and the kind of plyometric training for making optimal neuromuscular adaptations in volleyball players. The aim of the present study was the effect of 10 weeks plyometric training with different methods on neuromuscular adaptations in college volleyball players.
Methodology: In this Quasi-experimental study, 30 subjects from 3 universities were divided into 3 equal groups based on a random sampling. At first Subjects familiarization and pretests were performed in a week. After pretest, the participants divided into three groups include, Daily wave and weekly wave trainig groups and one control group. plyometric training program were carried out for 10 weeks (3 sessions per week) for all two trainig groups. In stages of pretest and posttest were taken tests of electromayographic amplitude and Mean power frequency of vastus lateralis and medialis muscles and test of Lower body muscular strength. The Training program consisted of 10 weeks with 3 sessions per week. 48 hours after the last training session, post tests performed. Data were analyzed using analysis of covariance and chasing test of LSD and paired t- test in significant level of p<0/05.
Results: The findings of this study showed that all two training periodizations improved significantly increases in vastus lateralis and medialis mean power frequency, electromayographic amplitude and Lower body muscular strength. Also Daily wave trainig group caused a significant increase in vastus lateralis mean power frequency compared to weekly wave trainig and control groups (p= 0/01, p= 0/003 respectively). Also Daily wave training group caused a significant increase in vastus lateralis (p=0/01) and medialis (p=0/006), electromayographic amplitude and Lower body muscular strength (p= 0/017, p= 0/012) compared to the weekly wave training group and not seen significant difference among of other groups.
Discussion: The findings of this study showed that all two training periodizations improved significantly increases in neuromuscular activity of hamstring and quadriceps in the landing phase. Also there was significant difference between the two periodizations of plyometric training in vastus lateralis mean power frequency and also in vastus lateralis and medialis muscles electromayographic amplitude and Lower body muscular strength. Therefore It's advisable to use the Daily wave training in planning the plyometric training for making optimum neuromuscular adaptations.
