Abstract

Background: Strength of leg musculature is crucial to generate propulsive force during rowing. The purpose of this study was to determine the relationship of isokinetic dominant leg strength and 2 km time trial on stationary rowing ergometer among male national rowers.


Methods: Seventeen male national rowers were recruited for the study. Their hip and knee isokinetic strength were determined in the sagittal plane at 60°/s angular velocity. The relationship between the hip and knee strength, and 2 km time trial performance were evaluated using Pearson correlation.


Results: The national rowers completed the 2 km time trial duration in 7.20±0.39 minutes. The hamstring to quadriceps ratio (H:Q) was significantly correlated to 2 km time trial performance (r=-0.491, p=0.045). No other significant relationships between hip and knee isokinetic strength and 2 km time trial performance were observed.


Conclusion: Increased isokinetic knee strength ratio (H:Q) may enhance 2 km time trial performance among male national rowers. Other isokinetic variables of hip and knee isokinetic strength were not significantly related to 2 km time trial.
