title: Possibility of Delay in the Super-Compensation Phase due to Aging in Jump Practice.
abstract: OBJECTIVE
  To investigate the possibility of a delay in the super-compensation phase due to aging in jump practice.
  
  
  METHODS
  This study evaluated records in three phases (approximately every five years) of a man who had been participating in Masters Athletics for over 20 years. After correcting for air temperature, which would influence the distance on a standing five-step jump using simple regression analysis, the performance curve of the super-compensation phase was calculated at each phase by curvilinear estimation to assess the relationship between the training interval and distance on the standing five-step jump.
  
  
  RESULTS
  A peak distance on the standing five-step jump was achieved after a training interval of 60 hours in the first phase; 75 hours in the second phase; and 88 hours in the third phase. That is, the peak distance tended to delay with aging.
  
  
  CONCLUSIONS
  It may be suggested that the super-compensation period would be delayed by aging in jump practice. We would like master athletes to refer this result and improve their performance.
