title: Postactivation potentiation of dynamic conditioning contractions on rowing sprint performance.
abstract: OBJECTIVE
  This study examined the post-activation potentiation effects of maximal dynamic contractions and gender on rowing sprint ability.
  
  
  METHODS
  Repeated measures.
  
  
  METHODS
  Thirty-four male (n=17) and female (n=17) university students with experience in rowing took part in this study conducted across three weeks. Following familiarisation of the 10-second maximal rowing performance test on a rowing ergometer during Week 1, participants were randomly allocated to either complete a control or experimental session during Week 2 and 3. One rowing performance test was conducted during the control session whilst two rowing performance tests were conducted during the experimental session separated by 6-min. The first rowing performance test during the experimental session was used to: (1) compare measures with the control session to assess day-to-day repeatability; and (2) induce post-activation potentiation effects for the second rowing performance test.
  
  
  RESULTS
  Based on effect size calculations, results showed moderate-large increases for average power output (+2.5%), peak power output (+1.5%) and power output during first stroke (+0.79%).
  
  
  CONCLUSIONS
  Maximal dynamic contractions on a rowing ergometer improved subsequent rowing sprint ability in recreationally experienced male and female rowers. Accordingly, dynamic conditioning contractions on a rowing ergometer may enhance subsequent sprint-start for rowing competition success.
