Abstract

Objectives: This study examined the post-activation potentiation effects of maximal dynamic contractions and gender on rowing sprint ability. Design: 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-minutes. 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.
