A verification phase performed after an incremental treadmill test resulted in a lower peak heart rate (p=0.001) and failed to elicit maximal values in some distance runners.
Cross-Sectional (n=16)
Does a verification phase improve the determination of true maximal oxygen uptake in distance runners compared to an incremental treadmill test alone?
A verification phase at a higher running speed after an incremental treadmill test may be inadequate for confirming maximal oxygen uptake in some distance runners.
p-value: p=0.001
This study investigated the utility of a verification phase for increasing confidence that a "true" maximal oxygen uptake had been elicited in 16 male distance runners (mean age (+/-SD), 38.7 (+/- 7.5 y)) during an incremental treadmill running test continued to volitional exhaustion. After the incremental test subjects performed a 10 min recovery walk and a verification phase performed to volitional exhaustion at a running speed 0.5 km.h(-1) higher than that attained during the last completed stage of the incremental phase. Verification criteria were a verification phase peak oxygen uptake or= 3%) lower than the peak values attained in the incremental phase. Further research is required to improve the verification procedure before its utility can be confirmed.
Midgley et al. (Sun,) conducted a cross-sectional in Distance runners (n=16). Verification phase vs. Incremental phase was evaluated on Peak oxygen uptake and peak heart rate (p=0.001). A verification phase performed after an incremental treadmill test resulted in a lower peak heart rate (p=0.001) and failed to elicit maximal values in some distance runners.
