Comparing the effects of six weeks of volleyball specific training on hard and soft surfaces on anaerobic power, vertical jump, agility and fat percentage of volleyball players

 
The aim of this study was to compare the effect of six weeks of volleyball specific training on the sand and lounge on anaerobic power, vertical jump, agility and fat percentage of volleyball players. For this purpose, 18 male volleyball players (Mean SD, age, 23.743.7 and weight 75.31 1.74) were randomly assigned to two groups of sand and lounge. Two groups performed a six-week specific volleyball training protocol on sand and lounge at maximal intensity. Anaerobic power, vertical jump, agility, and body mass index (BMI) were measured at pre- and post- training for both groups. Between and within groups comparisons were made by using independent and dependent t-test. The results of the study revealed that training on sand compared to lounge had a significant (P<0.05) effect on vertical jump, anaerobic power and agility and caused improvements in these variables. Fat percentage decreased significantly in the sand group (P<0.05). Base on the findings of the present study, it could be concluded that the specific volleyball training on the sand causes more improvements in physical fitness and capability than training on lounge. Therefore, this kind of training protocol could be used by athletes and coaches during conditioning period in pre-season.
