Abstract

Aim: The heart rate deflection point (HRDP) is a downward or upward change from the linear HR-work relationship which is considered as a criterion for planning of the aerobic exercise intensity. The aim of this study was to evaluate the AGREEMENT of the time vs. distance dependent protocols for determination of Heart Rate Deflection Point (HRDP) in sedentary young girls.Methods: Twenty sedentary young girls selected as subjects and divided randomly to the time dependent (group A; mean±SD Age of 19.8±1.02 years, Weight of 57.8±7.74 kg, Height of 163.11±7.14 cm, and Vo2max of 32.89 ml/kg/min) and distant dependent (group B; mean±SD Age of 20±1.15 years, Weight of 57.30±12.14 kg, Height of 162.80±7.91 cm, and Vo2max of 33.21 ml/kg/min) groups. Subjects performed the time and distance dependent incremental exhaustive exercise tests in two separate sessions with 72 h rest intervals. Determined HRDP by the gas analysis system was considered as criterion method. Polar Vantage Sport Tester XL was used to monitor heart rate performance throughout the protocols. Data were analyzed by the means of the graphical Bland-Altman as well as the Interclass Correlation Coefficient (ICC) statistical methods.Results: Results revealed that the time dependent protocol has no AGREEMENT with the criterion method (ICC=-0.0191; ±1.96; 95% CI=-8.9 to+26.5 b/min); However, we showed moderate AGREEMENT between the distance dependent protocol and the criterion method (ICC=0.4002; ±1.96; 95% CI=-5.1 to+35.5 b/min).Conclusion: According to this study results, it can be concluded that the distance dependent protocol in comparing with the time dependent protocol have higher AGREEMENT with the criterion method; However, use of this protocol for determination of HRDP is doubtful.
