Brief summary
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.
Detailed description
Study Design: Randomized Clinical Trials Sample size: 78(39 for each group) Sampling technique: Non-probability, Purposive sampling technique Study Setting: * Pakistan Football Federation, Lahore * Model town soccer club, Lahore Inclusion criteria: * Male soccer players * Age 18 to 30 years. * A minimum of two years of experience in Regular training * Athletes with BMI 18.5kg/m2 -24.9kg/m2 Exclusion criteria: * History of lower extremity surgeries (e.g., ACL reconstruction or any major surgery) in the past year * Athletes having consumption of Drugs which may influence Athlete performance. * Any systemic illness * Any musculoskeletal disorder * Pre-existing Cardiovascular and respiratory (exercise-induced asthma) conditions Tools: * Aerobic capacity:20-meter shuttle run test (ICC =0.96) * Muscle strength :1RM Back squat test (ICC=0.91-0.99)
Interventions
OTHERAccentuated eccentric resistance training ( 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 (heavy resistance). The level of exercise progressively increased throughout the 8-week program, by increasing the strength of resistance bands. In group A, participants executed the Eccentric Phase for 2-4 seconds and Concentric phase for 1-2 seconds. 12 Comparison of accentuated eccentric and concentric resistance training in athletes
OTHERConcentric Resistance training (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 (heavy resistance). The level of exercise progressively increased throughout the 8-week program, by increasing the strength of resistance bands. In group B, participants executed the Concentric Phase for 2 4 seconds and Eccentric phase for 1-2 seconds.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 1-RM Back Squat test | 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 | 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) |
