Comparator Agent  NOT APPLICABLE  NOT APPLICABLE 
Intervention  plyometric and resistance training  1. Participants will be involved in 6 week of combined jump and weight training program. Rest of two days will be given after each session for full recovery. 2. In first session, jump training will be given. In this training, various jumps will be performed on ground and box. This include Two-foot ankle hop, Squat jump, Box drill – double-leg jump to box, Depth jump. Frequency of training will be 2 sets per session and one set will have 10 reps of each exercise. The duration between sets will be 2 to 3 min for rest. 3. In second session, weight training will be given. In this training various exercises will be given in which weight will be lifted. This includes high bar squat, leg press, seated and standing calf raises. Frequency of training will be 3 sets per session which will range from 67% to 80% of 1RM. The duration between sets will be 1 min for rest. 4. The training will be done in same sequence for 6 weeks with rest of 2 days after each session.

Brief Summary
Modification(s)  

The aim of the study is to investigate the influence of combined plyometric and resistance training of lower limbs on:  

–     the stiffness of Achilles and patellar tendon

–      Jump height

Hypothesis - combined plyometric and resistance will improve both tendon stiffness and jump height

Results- There was a significant improvement in both tendon stiffness of Achilles and patellar tendon and as well as jump height in all the participants.
