Counting Talk Test Measurements and the Relationship to Heart Rate for Exercise Prescription: 1767 Board #28 May 31 2

PURPOSE: The purpose of this study was to examine the relationship between 2000-m rowing performance and the parameters of a three-minute all-out rowing test in collegiate club rowers. METHODS: Ten (F=6, M=4) collegiate rowers (mean ± SD; age 19.3 ± 1.2 y; height 176.7 ± 10.0 cm; weight 75.6 ± 19.5 kg) completed a peak power test to determine peak power output (PPO) and a one-minute all-out test, a three-minute all-out test to determine end-power (EP) and work done above end-power (WEP), and a 2000-m time trial on a rowing ergometer. Testing days were separated by 72 hours and began with a five-minute warm-up on the rowing ergometer. The peak power, one-minute, and three-minute tests were all completed on a damper setting 10 whereas the 2000-m time trial was completed at a self-selected damper setting. Repeated measures ANOVA was used to compare PPO for all the tests and Pearson’s product moment correlations were conducted to measure the relationships between 2000-m time and the parameters of the all-out rowing tests. RESULTS: The strongest relationship with 2000-m time was average power for the 3-minute test (r = -0.968, p <0.001). Additionally, 2000-m time was significantly correlated with EP (r = -0.931, p <0.001), average power during 1-minute test (r = -0.784, p <0.01), and PPO (r = -0.762, p =0.01). Work above end-power (WEP) was significantly related to PP of all the tests. There were significant differences between PP for all tests (p < 0.01). CONCLUSIONS: These results suggest that a single 3-minute all-out rowing test can predict both peak power output and 2000-m time, therefore rowing coaches could use this test to more efficiently assess rowers.
