Abstract: A method includes steps of: measuring a variation in joint angle of a knee of a cyclist to obtain joint angle data; sensing a torque applied on a crank of a cycle or pedaling force applied to a pedal of the cycle to obtain force data; measuring an angular position of the crank to obtain crank angle data; measuring an electrical potential variation of a measured muscle of the cyclist to generate a measured EMG signal; estimating activation data and joint moment data based on aforementioned data and characteristics data; converting the activation data into estimated EMG signals based on the measured EMG signal and the activation data; and computing a coactivation parameter based on the aforementioned EMG signals.

Abstract: A method for imbalance warning to be implemented by a wearable electronic device positioned on a body part of a user includes steps of: obtaining acceleration data during a calibration period; obtaining an angle threshold based on the acceleration data thus obtained; obtaining angular velocity data during a unit of time; calculating a sway angle based on the angular velocity data; determining whether the sway angle thus calculated exceeds the angle threshold; and when it is determined that the sway angle exceeds the angle threshold, outputting a signal that indicates imbalance of the user.

Abstract: A musculature training device is disclosed. The musculature training device includes an attaching member, a fixing-and-adjusting member coupled to the attaching member, and an elastic member connected to the fixing-and-adjusting member, wherein the fixing-and-adjusting member sets an initial length of the elastic member. When a user move his/her body or limbs to deform the elastic member and change the initial length of the elastic member, the elastic member generates a restoring force that provides a resistance needed for a musculature training around the user's joint. Therefore, the user can train himself anytime and anywhere. Moreover, the user is allowed to perform a single joint musculature training to avoid sport injury and improve training effectiveness.
