Effectiveness of armrest prototype on muscle activity among male motorcyclists

Introduction: Motorcycle is one of the main transports in Malaysia that has been used for decades either daily life activities or working. Motorcyclist most important element when issues are related to motorcycle. Therefore, this study will be able provide evidence reduce level electromygraphy (muscle activity) with intervention armrest prototype which indirectly riding discomfort during prolonged process.Method: In 2 different sessions (with and without armrest), 102 respondents were instructed ride a motorcycle hours laboratory simulator system. The video screen presented by projector view as motorcyclist road scenery computer generated simulating daytime condition. Besides that, Electromyography (EMG) signals assess recorded muscle activity right left arm surface electrode attached. Results: Muscle showed there reductions electromyography levels both arm’s muscles. There positive effect exertion changes (%) on flexor carpum radialis (right=24.54%, left=23.98%) ulnaris (right=8.18%, left=10.62%) muscles arms usage prototype.
