Key result
Afternoon rowing time trials were 3.4 seconds faster (95% CI 0.9-5.8 s) and yielded higher mean power output (347 vs 337 W; P=0.04) than morning trials, with similar cerebrovascular responses.
Why the study?
Does the time of day (afternoon vs morning) improve rowing performance and alter cerebrovascular responses in male rowers?
Does the time of day (afternoon vs morning) improve rowing performance and alter cerebrovascular responses in male rowers?
Mean Difference: 3.4 (95% CI 0.9–5.8)
Rowing performance is significantly better in the afternoon compared to the morning, but this diurnal variation is not explained by differences in middle cerebral artery velocity or cerebral oxygenation.
No takes yet. Share an insight, caveat, or question.
Afternoon rowing may confer performance gains in males; hypothesis-generating for mechanisms and should not yet change training practice.
Faull et al. (2014) studied this question. Afternoon (16:00 h) exercise vs. Morning (07:00 h) exercise was evaluated on 2000-m ergometer time trial performance (MD 3.4 s faster, 95% CI 0.9-5.8). Afternoon rowing time trials were 3.4 seconds faster (95% CI 0.9-5.8 s) and yielded higher mean power output (347 vs 337 W; P=0.04) than morning trials, with similar cerebrovascular responses.
