Correlation Between Anthropometric Measurements and Muscle Performance Based on Endurance Test

Abstract

The purpose of this paper is to evaluate the correlation between anthropometric measurements and muscle performance based on endurance test at 50% MVC. Eight VT protocols (based on the different combinations of vibration frequency (35 and 45 Hz), amplitude (3 g ± 0.5 g, and 9 g ± 0.5 g), and exposure duration (30 and 60 s)) were given to the participants from two groups (56/group): persons with a sedentary lifestyle (SL) and a group of construction workers (CW) for 4 days. EMG signals were acquired from four muscles, namely flexor carpi ulnaris (FCU), flexor digitorum superficialis (FDS), extensor carpi radialis brevis (ECRB), and extensor carpi ulnaris (ECU) of the right forearm. The results showed a significant correlation (p < 0.001) between MVC grip strength with age, height, palm length, palm circumference, and forearm circumference for both groups. In addition, endurance time was significantly positively correlated (p < 0.05) with height and palm length for SL group, whereas for CW group with age, weight, palm length, palm circumference and forearm length. It can be concluded that Pearson’s correlation test suggested forearm circumference followed by weight and palm circumference was the most influential factor affecting the grip strength and palm length generally served as a better predictor for grip endurance time.
