Physiological responses obtained during exercise on the StairMaster Gauntlet with and without the use of hands
Abstract
This investigation was designed to determine if there were
sig diffs in the physiological responses (VO,, VE, METS,
RER, Kcals, HR, and RPE) with hands (WH) or without hands
(WOH) during exercise on the StairMaster Gauntlet (SM). Two
discontinuous protocols utilizing 6, 8, 11, 14, and 17 METS
were performed on 20 healthy college females. The ANOVA
indicated there were sig (p c .05) diffs between all stages
and methods WOH condition which resulted in higher values.
Since the ANOVA indicated a sig (p c .05) interaction, the
Bonferroni method indicated that all values representing
V02, VE, METS, Kcals, and HR were sig (p c . 01) higher WOH.
The RER at 11 and 14 METS were sig (p C .Ol) lower WH. The
RPE at 8, 11, and 14 METS were also sig (p c .01) lower WH.
As the intensity increased, the differences in methods also
increased for all physiological variables except HR. WH
was found to overestimate the values at the higher
intensities. It was concluded that the use of handrails
during SM exercise decreases the metabolic requirements of
exercise.
