Comparison Of Ventilatory Measures And 20 Km Time Trial Performance, Willard Peveler
Comparison Of Ventilatory Measures And 20 Km Time Trial Performance, Willard Peveler
International Journal of Exercise Science
International Journal of Exercise Science 10(4): 640-648, 2017. Performance threshold measures are used to predict cycling performance. Previous research has focused on long time trials (≥ 40 km) using power at ventilatory threshold and respiratory threshold to estimate time trial performance. As intensity greatly differs during shorter time trails applying findings from longer time trials may not be appropriate. The use of heart rate measures to determine 20 km time trial performance has yet to be examined. The purpose of this study was to determine the effectiveness of heart rate measures at ventilatory threshold (VE/VO2 Plotted and VT determined …

International Journal of Exercise Science
International Journal of Exercise Science 10(4): 592-603, 2017. Heart rate deflection point (HRDP) can be determined through different mathematical-modeling procedures, such as bi-segmental linear regression (2SEG) or maximal distance model (Dmax). The purpose was to compare heart rate (HR) and oxygen consumption (VO2) at HRDP when using 2SEG and Dmax, and to examine their relationships with respiratory compensation point (RCP) and running performance. Nineteen participants completed a graded exercise test (GXT), to determine HRDP and RCP, and a 5km treadmill time trial (5Ktime). No differences were found in HR or VO2 when comparing HRDP2SEG …
