Forearm Emg During Rock Climbing Differs From Emg During Handgrip Dynamometry, Phillip B. Watts, Randall L. Jensen, Edward Gannon, Randy Kobeinia, Jeremy Maynard, Jennifer Sansom
International Journal of Exercise Science
Grip force, as measured via handgrip dynamometry, is often given importance in the study of rock climbing performance. Whether handgrip dynamometry produces a degree of muscle activation comparable to actual climbing has not been reported. Furthermore, the degree and variability of muscle activation for various configurations during climbing are unknown. The purpose of this study was to record forearm EMG responses for six hand configurations during climbing and to compare these responses to a maximum handgrip test. Five experienced climbers signed informed consent to participate in the study. Subjects performed four moves up (UP) and down (DN) on an overhanging …
