The Use of an Indoor Rowing Ergometer Test for the Prediction of Maximal Oxygen Uptake

based version of the multi stage fitness test.Methods: Forty one participants (25 men, 16 women; mean  ± SD; age 21 ± 5.3 years, height 175.4 ± 8.1cm, body mass 71.4 ± 12.6 kg) completed in a counter-balanced design: a treadmill running maximal oxygen uptake test (Treadmill - VO2max), a 2,000 m timed
row and an incremental rowing maximal oxygen uptake test (IRT - VO2max) where stroke rate was increased by one stroke each minute. A student’s paired sample t-test was used to determine differences in maximal oxygen uptake (VO2max) and heart rate (HRmax) and a Pearson correlation coefficient to measure the relationships between VO2 during tests. Results: VO2max values were significantly higher in treadmill - VO2max (44.7 ± 6.5 ml•kg-1•min-1) than IRT - VO2max (42.2 ± 7.3 ml•kg-1•min-1; P<0.05). Maximum heart rate was significantly higher during the treadmill - VO2max (192 ± 10 beats.min-1) compared to the IRT - VO2max (184.3 ± 10.6 beats.min-1; P<0.05). A significant correlation was observed between treadmill - VO2max and the IRT - VO2max for VO2 (r=0.67). Gender specific linear regression equations were created to predict VO2max on the IRT from submaximal data (Males: Predicted VO2max (ml•kg-1•min-1)=2.30 (x) + 20.8, SEE=4.5; Females Predicted VO2max (ml•kg-1•min-1)=1.93(x) + 19.4, SEE=3.7). Conclusion: This new stroke rate based IRT provides a continuous test to exhaustion with minimal equipment which is suitable for the regular gym user to monitor their cardiorespiratory fitness.
