The Effects Of Applied Grip Force, Frequency And Duration On Ratings Of Perceived Exertion, Jessica Lynne Gall

Theses and Dissertations

This study investigates the interactions of various combinations of frequency and duration that result in the same duty cycle at a given applied grip force (measured in % maximum voluntary contraction (MVC)) to determine their relative effect on perceived exertion. Eight female subjects (median age 20.5 years) performed 27 randomized trials containing combinations of dynamic grips, performing each combination twice. Each session contained three 25 minute trials, with a minimum of 12 minutes of rest between trials. The design used a 3x3x3 factorial protocol: i) 3 grip forces (10%, 25%, 40%) ii) 3 duty cycles (25%, 50%, 75%) iii) 3 …
