Abstract

This study was conducted to study the effect of rowing training on peak oxygen uptake (VO2peak), resting stroke volume (RSV), and average power (AVGPWR) of stroke survivors. A pilot study, a test-retest study was conducted to develop a rowing­ramp protocol (RRP) as cardiopulmonary exercise testing (CPET) before a real test was performed to test the effectiveness of rowing training on VO2peak of 11 stroke participants. The retest study was conducted to study its reliability as CPET in this study AVGPWR, peak heart rate (HRpeak), Modified Borg Dyspnoea Scale (MBDS), and respiratory exchange ratio (RER) were measured during RRP test. Both tests showed excellent reliability, r = 0.946, P <0.001 for VO2peak, r = 0.915, p< 0.001 for AVGPWR, HRpeak, r = 0.964, p<0.001, MBDS, r = 0.659, p<0.027, and RER, r = 0.838, p<0.001. Reliability coefficient, r showed excellent reliability of all the variables. Thus, RRP was reliable as CPET to measure VO2peak of the stroke survivors. Sixteen patients (nine male; seven female), age (47.69 ± 14.225 years), weight (70.04 ± 14.623 kg), and height (162.15 ± 9.748 011) underwent a 12-week rowing training which consisted of both high-intensity interval training (HIIT) and moderate rowing (MR) types of training. RRP was conducted after every five weeks of training to measure VO2peak and AVGPWR. Electrical bioimpedance measurement using Biopac System (MP36) noninvasive method applied to measure RSV value before and after 12 weeks rowing intervention was applied. Mean ± SD of VO2peak (17.544 ±8.749 ml/min/kg to 22.619 ± 9.003ml/min/kg), AVGPWR (28.173 ± 15.093 W to 45.209 ± 21.226 W), and RSV (93.315 ± 42.482 ml to 121.560 ± 84.126 ml) showed an improvement from pre to post test 3. F values showed a statistically significant value for VO2peak and AVGPWR, F (3, 45) = 8.056, p = 0.001 and F (3, 45) = 19.059, p = 0.001 respectively. The results of paired t-test, t = -3.538, p = 0.003; t = -6.021, p = 0.001; and t = -1.343, p = 0.206 respectively showed VO2peak and AVGPWR showed a significant p value (p < 0.05). In this study, a regression test was performed to study the relationship between VO2peak and AVGPWR. VO2peak was expected to increase 0.373 ml/kg/min for a unit of increased in AVGPWR. Hence, there was a positive linear relationship recorded between VO2peakand AVGPWR (
