Abstract
Physiology is believed to be the most important determinant in rowing
performance that can help rowers win or lose tens of seconds in a race. However, there
is also the role of biomechanics and rowing technique to apply the rower's present
physiological fitness level most effectively. The effects of physiological and
biomechanical factors on rowing performance have been tested in many previous
studies but currently there is no study that combines the physiological and biomechanical
factors in determining rowing performance. The purpose of this study was to investigate
the biomechanical and physiological determinants of 2km rowing performance on slides
ergometer. Ten state-level rowers were recruited to participate in this study. Three tests
were completed to gather the data on aerobic, anaerobic, anthropometry and
biomechanical variables and also 2000 m rowing performance time. Pearson's
correlation test was used to determine correlation of these with 2000 m time. Result
showed that aerobic capacity, anaerobic capacity and biomechanical variables were
correlated with 2000 m time. Peak power (r = -0.937) and knee angle at catch at 1200 m
(r = 0.888) were the major determinants of ergometer rowing performance, followed by
knee angle at finish at 2000 m (r = -0.872), hip angle at catch at 2000 m (r = 0.85), body
fat percentage (r = 0.828), hip angle at finish at 800 m (r = -0.807), body height, post-test
lactate and oxygen uptake (VO2). The findings could be use for training design and
recruitment. More time should be allocate to improve muscle power. Increase in strength
and balance on muscles around hip and knee areas, particularly the hip and knee flexors
may increase performance and also possibly prevent muscle injury.
