Abstract
This study was conducted to evaluate the differences of physiological and
biomechanical variables during 2 km rowing time trials on a stationary versus
dynamic ergometer. Ten state-level rowers (male: 6, female: 4) voluntarily
participated in the study. Two sessions of 2 km time trial were conducted: one
on a static ergometer and another on a dynamic ergometer. Data on oxygen
consumption, blood lactate concentration, maximum heart rate, stroke rate,
time to completion and lower limb angles at sagittal plane were collected and
analysed during the tests. A paired T-test was used to compare the physiological
and biomechanical variables across stationary and dynamic ergometer. Stroke
rate, maximum heart rate, drive to recovery phase ratio and VO2max showed
statistically significant differences during 2 km rowing time trials on stationary
versus dynamic ergometer. Moreover, VO2max was inversely related with high
correlation to time to completion of 2 km rowing test on both ergometers.
Height, body fat and VO2max are the major determinants of 2 km rowing time
trials on stationary and dynamic ergometer. The outcomes from this study are
important to enhance rowing performance especially for rowers.
