Resistance Exercise Training to Improve Bone and Articular Cartilage Health in Women

The exercise programme involves two supervised sessions per week at University. Each session will involve 30-40 minutes of exercise, comprising warm-up , two main exercises: a hack squat and calf raise using a hack squat machine, and core exercises. After a warm-up period involving 5 minutes cycling and one set of 5 conventional repetitions at 40%1RM, the ballistic training group will complete eccentric phase hack squat exercise in approximately 3 seconds and the concentric phase as fast as possible with throwing type contractions. If participants can, participants will be allowed to take off in the concentric phase. To maintain high velocity in this group, lower loads will be used compared to the conventional group. The load will be decided according to regular maximal muscular strength test (1RM) to use of the correct weight for training (in proportion to the strength). Participants will start off using light weights and these will increase as participants become stronger.
