摘要

In the flourishing society, aerobics as a sport event that can build one’s body and cultivate one’s taste, ispopular among ordinary people, but due to professional knowledge deficiency, mass may unconsciously generate injuriesin body when taking aerobics exercise, in order to reduce occurrence rate of such injuries, the paper firstly gets dynamicsrelations and arms rotational inertia when aerobics athletes exercise upper limb inward and outward rotation motion byresearching, gets that aerobics athletes’ arms potential energy size when exercise upper limb inward and outward rotationmotion, and according to momentum theory of transmitting from near-end to far-end, athletes can strengthen elbow jointmomentum through shoulder joint effective braking effect, and then transfer momentum to wrist joint by elbow jointbraking to have end acceleration effects. It also gets forearm angular speed should be bigger than that of upper arm so thatcan more beneficial to elbow joint acceleration. And it gets that when aerobics athletes take upper limb inward andoutward rotation motion, due to it should let forearm angular speed to be bigger than upper arm’s angular speed to driveelbow joint acceleration, athletes should let elbow joint speed to be more faster than shoulder joint in the process, and thenshoulder joint is likely to suffer injuries because of braking, by comparing, elbow joint injury extent is far less than that ofshoulder joint, athlete can take some corresponding prevention measures by referencing the result.
