OBJECTIVE To conduct a detailed analysis of hamstring injuries sustained in English professional football over two competitive seasons. METHODS Club medical staff at 91 professional football clubs annotated player injuries over two seasons. A specific injury audit questionnaire was used together with a weekly form that documented each clubs' current injury status. RESULTS Completed injury r...

Hamstring muscle injuries occur during high-speed activities, which suggests that muscular strength at high velocities may be more important than maximal strength. This study examined hamstring adaptations to training for maximal strength and for strength at high velocities. Physically active men (n = 25; age, 23.0 ± 3.2 years) were randomly divided into: (1) a resistance training (RT, n = 8) g...

Introduction: The slump test is used in athletes with suspected hamstring strains to determine the presence of neural mechanosensitivity. Other than cadaveric investigations, limited evidence exists regarding this test with respect to the neuromuscular system. Aim: To examine the effect of the slump test on local muscular and neural structures in the posterior thigh in athletes with hamstring i...

CONTEXT There is a wide spectrum of hamstring-related injuries that can occur in the athlete. Accurate diagnosis is imperative to prevent delayed return to sport, injury recurrence, and accurate clinical decision making regarding the most efficacious treatment. EVIDENCE ACQUISITION This review highlights current evidence related to the diagnosis and treatment of hamstring-related injuries in ...

The hamstring muscle group is a vital constituent to injury prevention and lower extremity rehabilitation. During closed chain activity, hamstring muscle fibers influence dynamic interaction between the pelvis, sacrum, femur and lower leg. The hamstring muscle group functions as a frontal and transverse plane stabilizer, influencing knee flexion deceleration and eccentric extension during forwa...

  Background: Studies have shown that 75% of men and 35% of women over the age of 10 have hamstring tightness. Hamstring tightness is one of the major causes of hamstring injury and loss of function. Dry needling which is a common intervention used by physiotherapists for the treatment of common various conditions can improve hamstring flexibility in less time than other interv...

The hamstring tendons are an increasingly popular graft choice for anterior cruciate ligament reconstruction due to preservation of quadriceps function and the absence of anterior knee pain post-operatively. Two commonly used hamstring grafts are a quadruple strand semitendinosus graft (4ST) and a double strand semitendinosus-double strand gracilis graft (2ST-2G). It has been suggested that con...

BACKGROUND Hamstring injury is a prevalent muscle injury in sports. Inconclusive evidence exists for eccentric hamstring strengthening to prevent hamstring injuries. One reason for this discrepancy may be the influence intervention non-compliance has on individual study estimates, and therefore pooled estimates. OBJECTIVE This systematic review aims to determine the effect of eccentric hamstr...

The purpose of this study was to characterize the effect of speed and influence of individual muscles on hamstring stretch, loading, and work during the swing phase of sprinting. We measured three-dimensional kinematics and electromyography (EMG) activities of 19 athletes sprinting on a treadmill at speeds ranging from 80% to 100% of maximum speed. We then generated muscle-actuated forward dyna...

OBJECTIVES To identify risk factors for hamstring injury at the community level of Australian football. METHODS A total of 126 community level Australian football players participated in this prospective cohort study. To provide baseline measurements, they completed a questionnaire and had a musculoskeletal screen during the 2000 preseason. All were monitored over the season. Injury surveilla...
