Thigh Muscles Electromyography Research

Abstract

The aim of this study is to examine the effect of body mass increase (32.46% and 64.92%) over two main muscles of the human musculoskeletal system. Therefore, were analyzed the thigh muscles. More precisely was captured the electrical activity of rectus femoris muscle and biceps femoris muscle. For this experiment was used a BIOPAC MP 150 data acquisition system. The experiment consisted in five trials, 15 seconds each, departing from siting and followed by three normal steps and a relaxation phase. The resulted data revealed that although the lower limbs muscle structure is extremely complex the two muscle in question retrieve a large amount of overload, given that in some cases the electrical activity doubles in amplitude.
