Study summary

To determine the effect of the eccentric exercise training on injury prevention and hamstring strength in football players.

Read the detailed description

Hamstrings injuries are common among footballers with a higher prevalence rate in male footballers. Despite the relatively high incidence of hamstring injuries in sports, no clear prevention methods have been identified. Most hamstring muscle injuries occur during an eccentric phase of any activity. Eccentric hamstring training has been used for injury prevention in recent years. The two distinguishing characteristics of eccentric muscle contractions have been well understood: 1) great force output; and 2) low energy cost to produce the force. Due to these distinguishing characteristics, eccentric exercise is widely used in injury prevention programs.

The aim of this study is to determine the effectiveness of eccentric training as compared to conventional training in hamstring muscle injury prevention and strengthing in football players.

Interventions

  • OtherECCENTRIC EXERCISE

    Eccentric Exercise training group will perform 8 weeks of protocol with a total 24 sessions for 45 minutes (3 session per week). During each 45 minutes training session, subjects will complete the warmup for 10 minutes, Eccentric Exercise training for 25 minutes and cool down 10minutes. All players will perform each repetition in a slow, controlled manner, 10 repetition and 3 sets in first 4 week and 15 repetition and 3 sets in last 4 weeks of all exercises for 45 minutes. Eccentric exercise training protocol is as follow: Prone Hamstring Curl, Seated TheraBand Hamstring Curl, Exercise Ball (or glider) Bridge with Curl, Stiff-Legged Deadlift, Single Leg Deadlift, Nordic Hamstring Curl.

  • OtherCONVENTIONAL EXERCISES PROGRAM

    The participant of the Control Group will perform 8 weeks of protocol with a total 24 sessions for 45 minutes (3 session per week). During each 45 minutes training session, subjects will complete the warmup for 10 minutes, conventional training for 25 minutes and cool down 10minutes. All players will perform each repetition in a slow, controlled manner, 10 repetition and 3 sets in first 4 week and 15 repetition and 3 sets in last 4 weeks of all exercises for 45 minutes. The exercise will be as follow: Side Lunges, Split Squats, Calf Raises.

What researchers measure

Primary outcomes

  1. Hamstring Strength

    Vertical jumps: The person puts chalk on their finger tips to mark the wall at the height of their jump. The person then stands away from the wall, and jumps vertically as high as possible using both arms and legs to assist in projecting the body upwards. Attempt to touch the wall at the highest point of the jump.

    Time frame: 8 weeks

  2. Anaerobic Capacity

    SPRINT FATIGUE TEST: A repeat sprint test of anaerobic capacity consisting of ten 30-second sprints. This is an anaerobic capacity test, which measures the ability to recover between sprints while maintaining the same level of strength.

    Time frame: 8 weeks

  3. Agility

    5-0-5 AGILITY TEST: The ability to turn 180 degrees is measured by the 505 Agility test. The test can also be modified for sport-specific testing by having the subject dribble a soccer ball, a hockey puck, or a basketball through the course.

    Time frame: 8 weeks

Secondary outcomes

  1. Injury Prevention ( FASH )

    FASH (Functional assessment scale for acute hamstring injuries) questionnaire is a self-administered questionnaire used for acute hamstring injuries assessment. It is a valid and reliable instrument for assessing and determining the severity of hamstring injuries in an athlete population. It is a 10-item questionnaire that look the ability of a patient to perform certain lower extremity activities. This is a self-report questionnaire that patient can rate difficulty and interference with daily life.

    Time frame: 8 weeks
