The effects of elbow flexion angles on handgrip force production among trained women

Abstract

The objective of this study was to determine the effects of elbow flexion angles on handgrip force production. 200 women involved voluntarily as participants in this study. Participants were required to perform handgrip dynamometer strength test in three elbow flexion angle conditions; i) 0˚ (full extension), ii) 90˚ and iii) full degrees. Participants were given three trials for each side (dominant and non-dominant) in all three elbow flexion angles. Results showed that in all elbow flexion angles, dominant handgrip force were higher compared to the non-dominant side. Besides that, performing handgrip with 0˚ elbow flexion produced greatest force followed by 90˚ and full elbow flexion. To conclude, testers need to standardize the handgrip strength test procedures as different in elbow flexion angles and the use of dominant/non-dominant sides were shown to significantly affect the force production.
