Abstract

Purpose: to evaluate the validity and reliability of heart rate control (HRC) at 80%, 65%, 50% age-predicted HRmax and intensity variance index (IV(subscript HRC)) index, as well as optimal predictive model on rowing ergometer. Methods: Sixteen rowers (7 males and 9 females, 18.9±2.08 yrs, height: 167.7±7.83cm, weight: 63.1±8.16kg) were recruited to participate in an incremental test (VO2max and W(subscript peak) obtained), and a 2000m performance test (2000max). In addition, 2 trials of 2000m rowing at 80%, 65%, 50% HRmax at least 24hrs apart were also performed, and time to 500m, 1000m, 1500m and 2000m were recorded to obtain HRC index. Results: Intraclass correlation coefficient (ICC) analysis showed that HRC and IV(subscript HRC) at different intensity of HRmax have high test-retest reliability (ICC=0.89~0.99, p<.05), and there was no significant difference between 2 HRC trials. HRC at different intensities of HRmax in 2000m rowing trials showed significant correlation with 2000max (r=.81~.90, p<.05), VO2max (r=-.76~-.85, p<.05) and W(subscript peak) (r=-.80~-.85, p<.05). Moreover, IV(subscript HRC) at different intensities of HRmax were also correlated with 2000max (r=-.82~-.87, p<0.05), VO2max (r=.72~.81, p<.05) and Wpeak (r=.80~.84, p<.05); All of which showed both HRC and IVHRC have good concurrent validity. Simple linear and stepwise regression analysis indicated that HRC and IVHRC also have high predictive validity (R^2=0.63~0.89, p<.05) in 2000max assessment. Conclusion: HRC and IVHRC indices were valid and reliable in applying on rowing exercise, which can be applied in monitoring exercise intensity and predicting performance on rowing exercise.
