About

This study will be randomized clinical trial and will recruit male soccer players aged 18-30yrs.Participants will be randomly divided into two groups with each group performing their program 3 times per week for 8 weeks.Group A will engage in Accentuated Eccentric resistance training ,using resistance bands and Group B will participate in Concentric Reistance training ,with similar resistance bands.

79 participants in 2 patient groups

Group A

Experimental group

Description:

The AERT group performed eccentric resistance training by Elastic Resistance bands for 3 sessions per week for 8 weeks. Each session included 3 sets of 10 repetitions with 2-3 mints of rest interval between each set. Participants in this group start with Yellow band (light resistance) and progressing through to purple band (high resistance). The level of exercise progressively increased throughout the 8-week program, by increasing the resistance of resistance bands. In group A, participants executed the Eccentric Phase for 2-4 seconds and Concentric phase for 1-2 seconds.

Treatment:

Other: Accentuated eccentric resistance training ( group A)

Group B

Experimental group

Description:

The CRT group performed concentric resistance training by Elastic Resistance bands for 3 sessions per week for 8 weeks. Each session included 3 sets of 10 repetitions with 2-3 mints of rest interval between each set. Participants in this group start with Yellow band (light resistance) and progressing through to purple band (high resistance). The level of exercise progressively increased throughout the 8-week program, by increasing the resistance of resistance bands. In group B, participants executed the Concentric Phase for 2-4 seconds and Eccentric phase for 1-2 seconds.

Treatment:

Other: Concentric Resistance training (group B)
