简要总结
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.

研究组 & 干预措施
Group A
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.
干预措施: Accentuated eccentric resistance training ( group A) (Other)
Group B
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.

结局指标
主要结局
1-RM Back Squat test
时间窗: 8 weeks
a warm up of 10 repetitions using an empty barbell in back squat position. After rest of 2 mints, Participants will perform same protocol with addition of (35 pounds) weight and goal is to perform maximum repetitions. At final phase, weight (35 pounds) and the maximum repetitions performed are counted. This count is then used in Epley formula to calculate the individual 1RM (32). Epley's Formula: 1RM = weight x (1 + (reps / 30))
20-MTR Shuttle Run test
时间窗: 8 weeks
The 20-meter shuttle run test, often called the "beep" or "bleep" test, requires participants to run back and forth continuously between two lines 20 meters apart, with a rhythm imposed by audio(beep). Starting at a slow pace, they must turn when signaled by the beeps. After about a minute, the pace increased, with the beeps occurring more quickly, requiring the runners to speed up. The speed increases each minute(level), with beeps becoming closer together. If a participant reaches the line before the beep, they must wait; if not, they receive a warning and have two more chances to catch up to the pace. A second warning results in elimination from the test. Calculation: VO2max = 18.043461 + (0.3689295 x TS) + (- 0.000349 x TS x TS)
