title: The relationship between maximal oxygen uptake and repeated sprint performance indices in field hockey and soccer players.
abstract: BACKGROUND
  The purpose of this study was to examine the relationship between maximal oxygen uptake and repeated sprint performance in field hockey and soccer players.
  
  
  METHODS
  
  
  
  METHODS
  a descriptive study on the aerobic-anaerobic performance of intermittent team game players.
  
  
  METHODS
  the study was conducted at the Sports Medicine and Research Centre.
  
  
  METHODS
  forty male national team game players (22.6+/-4.2 years; 1.73+/-0.07 m and 63.7+/-6.2 kg) were involved in the study.
  
  
  METHODS
  all subjects completed a treadmill run test to exhaustion to determine maximal oxygen uptake and 8x40 m sprints either on the field or running track to determine repeated sprint ability performance.
  
  
  RESULTS
  Body mass-normalised maximal oxygen uptake of 58.0+/-4.9 ml x kg(-1) x min(-1) of the group is comparable to values reported in the literature for team game players. No significant correlations were established between the fastest 40 m sprint time and maximal oxygen uptake (r=-0.21 and -0.08, p>0.05). Moderate correlations were established between maximal oxygen uptake and total time for the eight sprints (r=-0.346 and -0.323; p<0.05).
  
  
  CONCLUSIONS
  Maximal oxygen uptake was not correlated with the fastest 40 m sprint time but was moderately correlated with total sprint time. Since the shared variance between maximal oxygen uptake and total sprint time was only 12%, improving aerobic fitness further will only be expected to contribute marginally to improving repeated sprint performance of the team game players. It remains possible that a high level of aerobic fitness enhances other aspects of match play in games like soccer and hockey.
