Study the difference between cycling on uneven and smooth roads in terms of the degree of activation of upper limb muscles. 2. Study if there is a pre-activation mechanism in upper limb muscles before contact with obstacle while cycling. Through the above purposes, to understand the body in riding a bike, the muscles are how to maintain the body balance, to avoid falling and injury. Methods: Delsys wireless, which were attached to affixed to wrist muscle, flexor carpi, biceps, and triceps of the upper limbs, were utilized to collect the parameters of muscle activation. The pre-activation mechanism time point is 0.5 seconds before contact with obstacle. The parameters were collected during a controlled cycling process with a fixed pedaling frequency: 50 rpm and travel distance: 40 m. Results: 1. There is a significant difference between cycling on the uneven and smooth roads in terms of upper limb muscle activation. 2. There will be muscle pre-activated process before hitting obstacles. Conclusion: 1. To maintain the balance on different pavement conditions, rider will adjust the cycling position and the output on different muscles. The results of this study show that there is a significant difference in the degree of activation of the wrist muscle, flexor wrist and brachial biceps on both sides of the conventional and non-conventional sides. The wrist muscles play the main roles of muscle groups when cycling on the uneven road. 2. Before contact the obstacles, there will be a pre-activation mechanism for rider to adapt to the environment and adjustment of muscles to avoid injury. Before the obstacle, the rider's wrist, flexor wrist and brachial biceps arose pre-activation to interact with the environment, stabilize the body, and avoid accidents.
