Effect of the shock absorber of the shock absorption benefits for upper arm

Abstract

The aim of this study was to explore the effect of handlebars shock absorbers on the human upper body muscles. We recruited ten male adult subjects to join our experiment. Subjects need to respectively rode the bike with shock absorber and without the shock absorber on the two kinds of vibration conditions (40 and 50Hz). The vibration generated by tire contact with the ground while riding was simulated through the self-made vibration simulation machine. The muscle activities of ulnaris, radialis, biceps brachii, triceps brachii of participant were collected by BTS Bioengineering® Wireless EMG meter. Descriptive statistics and one-way ANOVA were adopted to analyze the data. The results showed only ulnaris muscle has reached statistically significant level (p < 0.05) under low-frequency shock conditions, the ulnaris muscle, and triceps brachii muscles has reached statistically significant level (p < 0.05) under high-frequency shock conditions.
