Detailed Description
The objective of the study is to determine the effects of plyometric training on vertical jumps and dynamic stability in volleyball players with chronic knee pain.
The study is randomized and single-blinded. Ethical approval is taken from ethical committee of Riphah Internatinal University, Lahore. Participants who meet the inclusion criteria will be enrolled and allocated in group A & B through random number generator by Non-probability Convenient random sampling technique. Subjects in Group A will receive plyometric training. Group B will receive general training.
The outcome measures will be assessed by Vertical jump test, Hop test and Y balance test
The data will be analyzed by SPSS, version 25. Statistical significance is P= 0.05.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Plyometric training Jumps in place. Standing jumps. Multiple hops and jumps. Box drills. Depth jumps. |
Other: Plyometric training
Jumps in place. Some examples include multiple vertical jumps while reaching an overhead object, squat jump, pike jump, or tuck jump.
Standing jumps. Examples include the single leg jump, maximal vertical jump ,standing long jump or lateral long jump.
Multiple hops and jumps. Examples would include multiple long jumps or cone hops performed in succession, such as 5 hops in a row
Box drills. Examples of these drills include box jumps ,repeated box jumps, and single leg box jumps.
Depth jumps. Examples include stepping off the box and landing, stepping off the box and jumping vertically immediately after landing, or stepping off the box, landing, and sprinting.

Outcome Measures
Primary Outcome Measures
- Vertical Jump Test [4 weeks]
The Vertical Jump test is designed to measure an athlete's lower body strength
- Hop Test [4 weeks]
In this test, the aim is to jump as far as possible on a single leg, without losing balance and landing firmly.
- Y Balance Test [4 weeks]
This is a portion of the Functional Movement Systems screen used to evaluate dynamic balance and functional symmetry in order to determine a person's risk for injury or return to sport readiness.
