Abstract
The outcomes from this study are important to enhance rowing performance especially
for rowers. Based on previous study, many papers focused more on aerobic (V02) and
anaerobic (Peak power) in rowing performance but no studies have evaluated the
biomechanical determinants of 2km time trial on stationary ergometer. Purpose: This
study was conducted to understand the biomechanical and physiological determinants
of 2km rowing perfonnance on stationary ergometer. Methods: 10 state-level rowers
were recruited (6 males, 4 females) with at least two years experience in competitive
rowing. Anthropometric, peak power, blood lactate, heart rate, V02, 20 kinematic
motion and stroke rate were recorded during 2km time trial, 30s Wingate anaerobic test
and 5 x 4 step test. Pearson's correlation was applied to evaluate the correlation of each
physiological, biomechanical and anthropometric variable to the time of 2km rowing
completion. Results: Peak power was significantly correlated to the time of 2km
rowing completion (r = 0.273; p= 0.044). There was a significantly high correlation of
V02 (r = -0.906, p = <0.001) to 2km time trial results. There was a significant
correlation between kinematics variables of knee angle at catch (r = -0.376) (p = 0.007)
at 1600m and 2000m (r = -0.436; p = <0.00 l ). Positive correlation was found of hip
angle at finish during the last sprint of 2000m (r = 0.203; p = <0.00 1) to 2km time trial.
Discussion: V02 and peak power showed the significant on correlation of physiological
variables during 2km rowing time to completion. Conclusion: The ergometer was a
good training tool for the athlete to develop fitness and training. Proper technique of
rowing should be emphasised during rowing on stationary ergometer to enhance
performance during time trial.
