Relationship between maximal oxygen uptake, within-set fatigue and between-set recovery during resistance exercise in resistance-trained men and women.

Background: The primary aim of this study was to examine the relationship between maximal oxygen update (V̇O) and within-set fatigue and between-set recovery during resistance exercise in men and women.

Methods: We examined the relationship between V̇O and various indices of fatigue and recovery during parallel squats (3 sets, 90 s rest, 70% of 1RM to failure) and isokinetic knee extensions (3 × 10 maximal repetitions at 60 deg/s, 45 s rest) in 28 (age 27.0 ± 3.
