Brief Summary

Circuit training is a formed type of training in which the trainees goes through a series of selected exercises of activities that are performed in a sequence or in a circuit. Plyometric training is an intense, advanced form of exercise in which the muscles are first stretched, then contracted (the pre-stretching makes the muscle contract with greater force). Plyometric training is one of the most popular training approaches adopted by coaches and strength and conditioning professionals in both, team and individual sports.

Detailed Description

Circuit training is a formed type of training in which the trainees goes through a series of selected exercises of activities that are performed in a sequence or in a circuit. Plyometric training is an intense, advanced form of exercise in which the muscles are first stretched, then contracted (the pre-stretching makes the muscle contract with greater force). Plyometric training is one of the most popular training approaches adopted by coaches and strength and conditioning professionals in both, team and individual sports. This study will be a randomized clinical trial and will be conducted in Pakistan sports complex. Non-probability convenience sampling technique will be used to collect the data. The sample size of total 28 athletes will be taken in this study. The participants will be divided into two groups: group I will follow plyometric training and group II will receive circuit training. The plyometric training program progressed from level one (weeks one and two; 1-2 sets of 10 repetitions) to level two (weeks three and four; 1-2 sets of 8 repetitions) and finally level three (weeks five and six; 1-2 sets of 6 repetitions). Plyometric training programs included both leg jumps, single-leg jumps, hurdle jumps, drop jumps, box jumps or lunge jumps.

The circuit training consists of 6 exercises, divided in 2 blocks (1st block contains

½ squats, bench press and pushups and 2nd block contains burpees, squat thrust and lunges) of 3 minutes. Cooper's test, Sprint test, Vertical jump test and Agility shuttle run test will be used to evaluate the results after 6 weeks

Arm && Interventions

Group	Intervention	Description
Plyometric training	Plyometric training	The plyometric training program progressed from level one (weeks one and two; 1-2 sets of 10 repetitions) to level two (weeks three and four; 1-2 sets of 8 repetitions) and finally level three (weeks five and six; 1-2 sets of 6 repetitions). Plyometric training programs included both leg jumps, single-leg jumps, hurdle jumps, drop jumps, box jumps or lunge jumps

Primary Outcome Measures

Name	Time	Method
AGILITY SHUTTLE RUN TEST	8 Week	The 30 foot (9.15m) Agility Shuttle Run is a test of agility, in which the participant runs back and forth between two parallel lines as fast as possible, picming up blocks of wood, for a total of 120 ft. There is a similar metric version of this test, the 4x10m agility run.
Vertical jump test	8 week	The Vertical Jump test is designed to measure an applicant's lower body strength. The applicant then crouches and using the arms and legs jumps as high as possible extending the dominant arm.; Upon reaching the top of the jump the applicant must tap the gauge "fins" to mark the jump height.
Sprint test	8 week	Sprints are used to primarily test an athlete's acceleration. Max speed is directly linked to initial acceleration so testing sprint times at smaller initial intervals give a picture of whether training is improving acceleration and therefore max speed.
Cooper's test	8 week	The Cooper 12 minute run is a popular maximal running test of aerobic fitness, in which participants try and cover as much distance as they can in 12 minutes. purpose: to test aerobic fitness (the ability of the body to use oxygen to power it while running)
