Abstract

Some sport activities such as skiing causes athletes to be constantly exposed to vibrations caused by rough terrain which can lead to muscle fatigue in many repetitions. The purpose of this study is to investigate the effects of musculoskeletal fatigue on vibration transmissibility coefficient and muscle activity in subjects are exposed to floor vibrations. For this purpose, 12 young men were exposed to floor vibrations in the squat mode at frequency of 12 Hz and intensity of 0.9 m/s2 to achieve complete fatigue. The results of this study show that the occurrence of the fatigue in the musculoskeletal system of the body increases the amount of both variables of the study simultaneously. In other words, increasing of the muscle activity alone does not indicate fatigue phenomenon. Because according to the results, increasing the amount of muscle activity without occurrence of the fatigue reduces the vibration transmissibility coefficient in the muscle.
