Badminton requires quick explosive movements to change direction, jump, lunge and flick the wrist which can predispose to acute ankle sprains. Repetitive stress can lead to too much stress on the achilles and patellar tendons, resulting in tendinopathy or to the shoulder and elbow causing tendinopathy in the rotator cuff or common extensor tendons. More specifically to badminton is the incidence of wrist injury due to the large range of movement at speed needed here which can place a lot of stress here.
