Aerobic responses to 12 weeks of exerstriding or walkins training in sedentary adult women
Abstract
were randomly placed in a walking (W = 30), exerstriding
(ES = 29), or control (C = 27) group. All Ss completed a
walking VO,max test prior to and after completing a 12 week
walking program. Metabolic responses were obtained each min
throughout the treadmill tests using standard open-circuit
techniques. HR and RPE were also obtained throughout the
tests. Both W and ES trained for 30--45 min per day, 4 days
per week at 70-85% of max HR. In addition, the ES group
used rubber tipped walking sticks (Exerstriders) to
supplement their traditional walking workout. None of the C
group's physiological responses to the VOzmax tests were
significantly (p >.05) altered. A slight increase (p < .05)
in max V, occurred from pre- to posttesting in E, but not
the W group. VO,max significantly (p < .01) increased by
7.6% (36.5 to 39.5 ml~~.k~-'.rnin-f'o)r the W and 7.7% (33.7
' to 36.5 ml-kg-"min-') for ES. Treadmill time significantly
(p < .01) increased by 17.9 and 20.7% in ES and W,
respectively. No difference in the changes between the ES
and W groups existed. There were no significant (p > .05)
differences in max R value, HR, or RPE for either groups.
Both groups exercised at the same intensity, but the
Exerstriders walked significantly (p < .05) slower than the
walkers. Both walking and using Exerstriders provide a
sufficient training stimulus to increase aerobic performance
in previously sedentary women. The physiological benefits
of Exerstriding can occur at a lesser training speed and
shorter distance traversed compared to walking.
