The Effect of Mode and Intensity on Vo2 Kinetics in the Severe Intensity Domain

PDF Version Also Available for Download.

Description

The purpose of this study was to evaluate the effect of mode and intensity on VO2 kinetics in the severe intensity domain. Seventeen participants completed 3-7 tests each on a cycle ergometer and treadmill. For each test, Tfatigue, VO2max, Tmean response, VO2GAIN, TVO2max and T@VO2max were determined. Linear regression techniques were used to describe the relationship between TVO2max and Tfatigue . VO2max values were higher in running. The VO2 response profile was faster for running than cycling and faster at higher intensities. The faster VO2 response in running may be associated with larger active muscle mass or differences in muscle ... continued below

Linear regression techniques were used to describe the relationship between TVO2max and Tfatigue .

VO2max values were higher in running. The VO2 response profile was faster for running than cycling and faster at higher intensities.

The faster VO2 response in running may be associated with larger active muscle mass or differences in muscle activation patterns. The faster response at higher intensities may suggest that VO2 response is driven by O2 demand.
