Comparison of Heart Rate, Ventilation, Maximal Oxygen Uptake, Lactate Level, and Recovery Rate During Two Types of Walking Graded Exercise Testing in Elite Race Walkers

PURPOSE The purpose of this study was to identify a sport-specific assessment for elite race walking athletes by comparing physiological responses different types graded exercise test (GTX) protocols.METHODS Six completed two protocols in randomized crossover design with 1 week interval between trials. Exercise time, oxygen uptake (VO<sub>2</sub>), ventilation (VE), and heart rate (HR) were measured each trial; the lactate level during recovery period.RESULTS VO<sub>2</sub>, VE, HR differed significantly trials (<i>p</i><.01~.05). time (<i>p</i><.01) VO<sub>2</sub> (<i>p</i><.05) protocols; however, VE did not differ significantly. During period, levels (<i>p</i><.01), but protocol.CONCLUSIONS These results suggest that modified GXT appropriate assess athletes.
