Brief Summary

With an average heart rate (HR) of more than 90% of the player's maximal HR, football is extremely taxing. The sporadic movements that occur throughout a game place a strain on the anaerobic and aerobic systems, accounting for roughly 30% of the latter's workload and 60% of the former. The capacity to shift directions and accelerate or decelerate on the court in order to make accurate shots and perform better is what determines footwork performance. Plyometric Training is a favored training technique for raising COD performance since it has a reputation for being a simple, quick, and efficient method of training. The core practice of combining resistance conditioning exercises with a dynamic warm-up can improve power output in badminton and create a post-activation performance enhancement (PAPE) impact. According to random sampling and sample size calculated by open epi tool, a total of 68 badminton players will be obtained from the badminton club of a Crescent sports club and Al-Fatah Sports Complex, Faisalabad. They will be divided into group A and group B according to the form of random sampling. Baseline markers for agility and speed will be taken before the start of the training and after the completion of training program. Group A will be engaged in a specially designed 30-minute concentric lower limb training program (squats, lunges and leg extensions) conducted by the researchers, before a 90-minute ordinary badminton training session conducted by the coach, 2 days per week for 8 weeks. Group B will be engaged in a specially designed 30-minute eccentric lower limb training program (wall sit, sitting straddle single leg and full squat) conducted by the researchers, before a 90-minute ordinary badminton training session conducted by the same coach, 2 days per week for 8 weeks.

Arm && Interventions

Group	Intervention	Description
Group A	Concentric Lower Limb Training Program	32 participants will be in experimental group A and will perform concentric lower limb training program including squats, lunges and leg extension exercises.
Group B	Eccentric Lower Limb Training Program	32 participants will be in experimental group B and will perform eccentric lower limb training program including wall sit, sitting straddle single leg and full squat exercises.

Primary Outcome Measures

Name	Time	Method
60 Metre Speed Test	8 weeks	This test requires the athlete to sprint as fast as possible over 60 metres; The athlete warms up for 10 minutes The assistant marks out a 60-metre straight section on the track with cones The assistant gives the command "GO" and starts the stopwatch The athlete sprints as fast as possible over the 60 metres The assistant stops the stopwatch as the athlete's torso crosses the finishing line and records the time The test is conducted three times The assistant uses the fastest recorded time to assess the athlete's performance
Lateral Change of Direction Test	8 weeks	To perform the test, the athlete warms up for 10 minutes The assistant places three cones 5 metres apart on a straight line The athlete stands by the middle cone (B), facing the assistant The assistant gives the command "GO" and points in a starting direction, right or left, and starts the stopwatch The athlete moves to and touches the first cone, returns past the middle cone to the far cone and touches it and then returns to and touches the middle cone The assistant stops the stopwatch when the athlete touches the middle cone and records the time The test is conducted four times - two in each starting direction (left \& right) The fastest time in each direction is used for accessing the athlete's performance
