This study was designed to determine if sig diff existed inphysiological responses (VO2 ,Ve, METS, R, kcal, HR, andRPE) between handrail assisted (HA) and nonhandrail assisted(NHA) StairMaster Gauntlet (SG) exercise tests on the SG. Twenty males,ages 21-30, performed 2 exercise tests on the SG. The testsconsisted of 4, 4 min stages, representing the SG;;spredicted MET values of 8, 11, 14, and 17, for each of thehandrail assisted conditions. Expired gases were analyzedwith the Quinton Q-Plex I and HRs were monitored with UNIQCICheartwatches. Individual ANOVAs revealed sig (p < . 0 5 )higher values for the NHA method for oxygen consumption(VO METS, kcal) and VE. Variables not exhibiting sig (p <.05f*dif f included HR, R, and RPE. Individual t-testsrevealed that values obtained for oxygen consumption weresig (p < .01) higher under the NHA condition for all stagesof testing. VE and RPE values were sig (p < .01) higherunder the NHA condition for stages 3 and 4 of the tests.Values representing R were sig (p c -01) higher for the NHAcondition for stage 4 only. No sig (p > .01) diff wereobserved between conditions for HR. The SG;;s estimated METlevels sig (p c .ol) overestimated actual MET expenditurewhen compared to the HA condition in stages 2 through 4.The NHA condition resulted in a sig (p < .01) overestimationof MET levels during Stage 1, but not for Stages 2 through4, when compared to the SGts estimated MET levels. Furtherstudies are needed to evaluate the possible inherentdifferences among sexes and fitness levels in regard to handsupport variations on the StairMaster Gauntlet and 4000 PT.
