title: Cardiorespiratory Fitness of University Volleyball Players and Sedentary Young People in Marathwada Region of Maharashtra Province in India.
abstract: BACKGROUND
  Volleyball is considered a physically demanding athletic sport; characterized by rapid acceleration, deceleration, and sudden changes of direction. It has been highlighted that aerobic capacity (VO2 max) which indicates cardiorespiratory fitness has a significant effect on the performance of athletes and is an important element of success in sports.
  
  
  OBJECTIVE
  The objective of this study was to compare aerobic capacity of university volleyball players from the region with that of matched sedentary controls. The secondary objective was to compare the findings with the aerobic capacity data reported in literature for the volleyball players and sedentary population.
  
  
  METHODS
  Sample size was calculated for detecting a large effect size (Cohen's d = 0.8) with α as 0.05 and power of study as 80% for two tailed hypothesis testing. By using Queen's college step test, VO2 max was measured in 30 male volleyball players in the age group of 20 to25 years and was compared with 30 age and socio-economic status matched controls with sedentary lifestyle.
  
  
  RESULTS
  The mean predicted VO2 max was 52.99 ± 5.13 ml/kg/min in volleyball players and 37.01 ± 3.94 ml/kg/min in controls. The difference in mean values of VO2 max (ml/kg/min) in volleyball players and controls was statistically highly significant with p-value less than 0.001.
  
  
  CONCLUSIONS
  The volleyball players showed a superior aerobic capacity compared with age and socio-economic status matched controls with sedentary lifestyle.
