Effects of Eccentric Hamstring Training in Prevention of Hamstring Injuries in Sprinters
Condition: Sport Injury
MeSH terms: Wounds and Injuries; Athletic Injuries
Study type: Interventional

Summary: 
      The goal of this clinical trail is to determine the effects of eccentric hamstring training,
      in prevention of hamstring injuries in sports involving sprinting among club level athletes.

      The main question it aims to answer is :

      - Will eccentric exercises have an effect in the recovery of hamstring injuries and injury
      prevention in sprint performance sports among club-level athletes.

      Participants will be divided into two groups. Control group will perform conventional
      training program and interventional group will perform eccentric exercises.
    

Detailed description: 
      The most frequent time-loss injuries in sports are hamstring injuries, which are particularly
      common in modalities that involve rapid accelerations and decelerations like high-speed
      running. The hamstring muscle group is more susceptible to stresses because of the way it is
      anatomically arranged.These injuries are more common in sprinters than in other
      athletes.Ballistic motions like sprinting are typical in most contact and non-contact sports.
      The most frequent type of activity during sprinting is the running stride. The muscles
      aggressively extend and contract throughout each stride, forcing the linked segments to
      accelerate and slow down.In most club-level sports like football, cricket, sprinters and
      rugby sprinting is a crucial component of the sports and defines the performance of the
      athletes. If the athlete is a good sprinter he will perform more efficiently in sports. As
      sprinting is a high-intensity activity and is beneficial for athlete's general health but
      there are many injuries involved among these athletes. The injury can be disastrous for the
      athlete, resulting in extended recovery time and the possibility of persistent damage.
      Injuries in professional athletes are disproportionately often hamstring-related.The most
      common form of hamstring injury is hamstring strain which can be caused due these reasons.
      Hamstring injuries can be divided into three types; Grade 1 which is a hamstring pull or
      strain, Grade 2 partial muscle tear and Grade 3 complete muscle tear. The hamstring muscle is
      very important as it is involved in generating forward motion. The cause of hamstring injury
      can be due to multiple activities but the most common is when athletes are sprinting at
      maximal speeds.
    

Intervention name(s): Conventional training program; Eccentric hamstring training
Intervention type(s): Other; Other
Intervention description(s): Conventional training program:
5-10 Repetitions ( 0.5-to 1-min rest);
Vertical jumps
Multiple forward jumps
Running exercises
Sprints alternating with slow jogging; Functional training along with specific eccentric hamstrings exercises i.e., prone hamstring curl, exercise ball (or glider) bridge with curl, Nordic hamstring curl, single leg deadlift. The exercise program comprises 3 sets of 15 repetitions once to twice per day for at least 12 weeks.
