Comparison of Harmoknee Versus Bounding Exercise Protocol in Football Players

This is a randomized clinical trial will recruit male football players aged 18-30 years who regularly participated in sports more than 3 years, with a BMI between 18.5-24.9 kg/m².Athletes with smoking habits, those following other specialized training programs, or those taking any drugs that could affect their performance, and had musculoskeletal injury in past 6 months will be excluded. The sample size will be 36 and participants will randomly divided into two groups (18 in each group): Group A: 8-week Harmoknee program, 3 sessions per week (45 minutes each, including warm-up and cool down). Group B: 8-week Bounding program, following the same schedule. The study will measure strength (1RM Test), balance (Star Excursion Test), agility (T-Test), and muscle power (5 Jump Test) at two points: pre-test (before starting) and post-test (after 8 weeks).

Treatment and study plan

Harmoknee protocol ( Group A )

Other

Group A will be selected randomly and assigned to 8-week Harmoknee exercise program 3 sessions per week, each lasting 45 minutes (5mins warm-up and 5mins cool down) for assessment of strength and balance.

Bounding protocol ( Group B )

Other

Group B will be selected randomly and assigned to 8week Bounding exercise program 3 session per week, each lasting 45 minutes (5mins warm-up and 5mins cool down) for assessment of strength, balance, agility and muscle power.

Primary outcomes

  1. Strength Test: 1 Repetition Maximum

    Time frame: 8 weeks

    The Epley formula is used to estimate a person's 1 Repetition Maximum (1RM)

    1RM=w (1+r/30) After performing warm-up with empty barbell in back squat position for 10 times, athlete can rest for 2 minutes. Then athlete 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 by athlete will enter in Epley formula to calculate 1RM of each athlete.

  2. Balance Test: Star Excursion Balance Test

    Time frame: 8 weeks

    The athlete stands on one leg in the center of a star-shaped grid, with lines extending in 8 extending at 45 angle. While balancing on one leg, the athlete uses the other leg to reach along each line as far as possible without losing balance. The maximum reach distance in each direction is recorded. The test is performed on both legs for three times, and the average of multiple trials is taken in centimeters. Calculate the distance in each direction as a percentage by following formula.

    Average distance in each direction (cm) = Reach 1 + Reach 2 + Reach 3 / 3 Relative distance in each direction (%) = Average distance in each direction / leg

  3. Agility Test: T-Test

    Time frame: 8 weeks

    Four cones are arranged in a "T" shape: one at the starting point (Cone A), two at the left and right points (Cones B and C), and one at the top (Cone D).The athlete starts at Cone A and sprints to Cone D (10m).From Cone D, the athlete side-shuffles to Cone B(5m), then across to Cone C(10m), and back to Cone D(5m).Finally, the athlete backpedals from Cone D to Cone A (10m).The time taken to complete the course is recorded. Each athlete completes three attempts, and the best time recorded by stop watch is used for analysis.

  4. Muscle Power Test: 5 Jump Test

    Time frame: 8 weeks

    The athlete starts behind a starting line, standing with both feet shoulder width apart. When ready, they are to perform five consecutive broad jumps non-stop, using a forward as well as a vertical jump style that allows them to gain maximum distance. They are able to use their arms assist the explosive movement and for balance. Paint or any ink will be used under his shoes to mark his steps correctly. The total distance covered after five jumps is measured from the starting line to the point where the athlete lands on the final jump. Each athlete completes two trials, and the best distance is recorded in cm.Rest periods of 1-2 minutes are provided between trials to prevent fatigue.
