Physiological and perceptual responses to sprint interval exercise using arm versus leg cycling ergometry.

ABSTRACT: Increases in power output and maximal oxygen consumption ( V˙O2 max) occur in response to sprint interval exercise (SIE), but common use of "all-out" intensities presents a barrier for many adults. Furthermore, lower-body SIE is not feasible for all adults. We compared physiological and perceptual responses to supramaximal, but "non-all-out" SIE between leg and arm cycling exercise. Twenty-four active adults (mean ​± ​SD age: [25 ​± ​7] y; cycling V˙O2 max: [39 ​± ​7] mL·kg^-1·min^-1) performed incremental exercise using leg (LCE) and arm cycle ergometry (ACE) to determine V˙O2 max and maximal work capacity (Wmax). Subsequently, they performed four 20 ​s bouts of SIE at 130% Wmax on the LCE or ACE at cadence ​= ​120-130 ​rev/min, with 2 ​min recovery between inte
