The Effects of Different Strength Training on Static and Dynamic Balance Ability of Volleyball Players

Abstract

The aim of this study is to examine the effect of different strength training on the static and dynamic balance ability of volleyball players. A total of 20 male volleyball players, aged between 18 and 25, are participated in the study who has been playing in national volleyball competition in Gaziantep. The subjects were divided into two groups according to the randomized method as experimental group (n=10, age:21.60±2.06) and control group (n=10, age:20.50±1.77). The experimental group was given a different strength training program for 3 days a week for 8 weeks. Both groups continued their regular volleyball practice. Leg strength, static and dynamic balance measurements were made before starting the different strength training in both groups and after the training was finished. Takei Leg Dynamometer used for leg strength measurement and Biodex Balance SD Isokinetic Balance Test for balance measurement. Paired Sample t test was used for intra-group comparisons and Independent Sample t test was used for statistical analysis of the data. When the pre-test and post-test measurements of the experimental group were compared, there were significant differences in leg strength, static (Double leg-Overall Postural Stability Index (OPSI), Right Leg-OPSI, Left Leg-OPSI) and dynamic (Right Leg- Overall Stability Index (OSI), Left Leg-OSI) balance scores (p<0.05). The control group showed significant significance in the Double leg-OPSI score (p<0.05). No other significance was found in the other data (p>0.05). As a result, it is considered that the different strength training applied to the volleyball players has a positive effect on the static and dynamic balance ability. It can be said that static and dynamic balance abilities of regular strength training may increase.
