Handgrip force using and not an arm support

Hypothesis: the handgrip generated using and not arm support is the same. We collect data using arm support considering three diferent positions of lexion angles, corresponding to shoulder and elbow at (a) 90°-90°, b) 135°-45° and c) 160°-20°. The dynamometer was adjusted to a 1 7/8" handgrip opening for all participants. Participants were asked to produce their maximum handgrip strength in each essay and Caldwell protocol was applied to standardized the data collection.
