Aerobic responses to 12 weeks of exerstriding or walkins training in sedentary adult women

[摘要] were randomly placed in a walking (W = 30), exerstriding(ES = 29), or control (C = 27) group. All Ss completed awalking VO,max test prior to and after completing a 12 weekwalking program. Metabolic responses were obtained each minthroughout the treadmill tests using standard open-circuittechniques. HR and RPE were also obtained throughout thetests. Both W and ES trained for 30--45 min per day, 4 daysper week at 70-85% of max HR. In addition, the ES groupused rubber tipped walking sticks (Exerstriders) tosupplement their traditional walking workout. None of the Cgroup;;s physiological responses to the VOzmax tests weresignificantly (p >.05) altered. A slight increase (p < .05)in max V, occurred from pre- to posttesting in E, but notthe W group. VO,max significantly (p < .01) increased by7.6% (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 ESand 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 theExerstriders walked significantly (p < .05) slower than thewalkers. Both walking and using Exerstriders provide asufficient training stimulus to increase aerobic performancein previously sedentary women. The physiological benefitsof Exerstriding can occur at a lesser training speed andshorter distance traversed compared to walking.
