Abstract
Rhythmic pumping of light hand-held weights while walking or running has become a popular approach to total body aerobic exercise. The use of handweights (HW) in conjunction with walking and running significantly increases the energy requirement of a given locomotor speed and adds variety to the choice of modes when prescribing exercise regimens (Auble, Schwartz, & Robertson, 1987; Francis &. Hoobler, 1986; Graves, Pollock, Montain, Jackson, & O'Keefe, 1987). Handweighted exercise can also be conveniently and accurately prescribed for use with other exercise modalities such as bench stepping (Goss, et al., 1987). Stepping up and down on a bench at varying frequencies while pumping handweights is a low-impact, space efficient form of total body aerobic exercise. However, little is known about the energy cost of this unique exercise modality. Such information is important if handweighted exercise is to be used in conjunction with bench stepping when prescribing both therapeutic and recreational training regimens. The purpose of this investigation, therefore, was to evaluate the energy cost associated with combined bench stepping and rhythmic pumping of light handheld weights.
