Study Arms:
- Jumping exercise (Type: EXPERIMENTAL): Physical therapy with a focus on specific jumping exercise. The jumping exercise will be performed for 12 weeks (3x/week), with a break of day between workouts. The 40-minute workout is completed 2 times under supervision in the clinic's internal training group for outpatients. 1 time they train on their own at home, based on a defined training program. The training process is documented by the training protocol.~The incipient exercise intensity is taking personal performance into account. The exercise intensity is increased by a progressive scheme.
- Strength exercise (Type: ACTIVE_COMPARATOR): Physical Therapy with a focus on stability and strength exercise. Strength exercise arm has also same duration of 12 weeks with comparable intensity. The program is according to a predetermined program. The 60-minute training is completed twice under supervision in the clinic's internal training group for outpatients.There is no contact with participants of other group.~Between the two exercise sessions there is a training free day. The training process is documented by the training protocol. The incipient exercise intensity is considering personal performance. The intensity is increased after workout usual principles. The exercises are described with clear image and load parameters. The training exercises are regularly monitored.

Based on this trial design, predict the completion outcome and termination type (if applicable).
