Comparison of the physiological adaptations to high vs. low stroke rate training in rowers

Abstract

Twenty five male and female novice and experienced rowers were matched on 2500 meter simulated rowing performance times and randomly assigned to either a low stroke rate (LSR, 16–18 strokes per min) or high stroke rate (HSR, 26–28 strokes per min) endurance training group. The heart rate intensity and distance rowed per session was equated for both groups. Endurance training was performed 4 times a week and training distance increased from 7.5 km per session to 12 km per session during 10 weeks. All subjects performed an identical strength training program twice a week on different days. Both groups significantly increased 2500 m performance time, VO2max, strength and anaerobic power. No significant difference was observed between groups for the 2500 m rowing time, the bench and leg press 1 RM and anaerobic power after training, respectively. However, there was a significantly greater increase in VO2max after HSR training. These findings suggest that, despite a difference observed in VO2max adaptation, a similarity in adaptation occurred in physical performance (simulated rowing), anaerobic power and strength after HSR and LSR training provided training intensity and volume are equated.
