FUNCTIONAL HAMSTRING: QUADRICEPS RATIO AND HAMSTRING INJURY INCIDENCE IN TRACK AND FIELD ATHLETES
… 1 University Track and Field team sustained hamstring strains in the 2010 season preventing practice and competition. Functional hamstring to quadriceps strength ratio was measured to study muscular imbalances in these athletes. The hypotheses were: 1) Athletes with previous hamstring …

Gait biomechanics following unilateral hamstring fatigue
Hamstring strain injuries (HSIs) are one of the most common non-contact injuries across many sports, costing athletes time in training and competition. HSIs are most often sustained during very high-speed running, typically occuring in the long head of the biceps femoris (BFlh). Athletes with prior …

Effect of fatigue on hamstring strain injury risk in soccer
Hamstring strains are one of the primary injuries within modern soccer match-play. The injury is well recognised by medical personnel, coaches and athletes as a major concern causing significant financial costs and lost time from training and matches. The temporal pattern of hamstring injury …

HAMSTRING INJURIES IN FOOTBALL: A COMPLEX SYSTEMS APPROACH THROUGH VIDEO ANALYSIS
Hamstring injuries remain the most frequent muscle injuries in football and continue to impose a substantial burden on player availability, performance, and club management. Despite the large body of literature on hamstring injury risk factors, recurrence, and rehabilitation, their incidence is …

Hamstring/quadriceps strength ratios: An analysis and a strength training study
This study was performed to examine the hamstring:quadriceps (H:Q) ratios of female soccer athletes, and to test the effects of a six week strength training program on these ratios. Twelve NCAA Division I female soccer athletes volunteered for this study. Subjects completed two practice sessions, a …

The Effect of Hamstring Lengthening on Pelvic Tilt and Lumbar Lordosis
<p>A direct correlation between hamstring tightness and severity of lower back pain (LBP) has been previously reported. Hamstring contraction creates knee flexion, hip extension and posterior pelvic tilt. Posterior pelvic tilt causes the lumbar spine to flatten (hypolordosis) which places pressure …

Modifiable risk factors of hamstring strain injury : assessment, performance and training
Hamstring strain injuries (HSIs), which are typically sustained during high velocity movements (i.e., sprinting or high velocity running), commonly involves the bicep femoris long head (BFLH). To date, the Nordic hamstring exercise (NHE) is the most effective training modality for reducing HSIs …

Effects of Eccentric Nordic Hamstring Exercise on Fascicle Length in Females
<p>The eccentric Nordic hamstring exercise (NHE) may be useful for increasing fascicle length (FL) of the bicep femoris long head and reduce the risk of hamstring strain injury. Compared to changes in hamstring strength, FL has been shown to reduce the risk of injury to a greater extent. While …

Concussion, neck, and hamstring injury aetiology and injury prevention in Rugby Union
ABSTRACT Background Concussion and hamstring injuries are two of the most frequently diagnosed injuries in Rugby Union. Neck and hamstring strength have been identified as a modifiable risk factor to decrease the severity and incidence of these injuries. As such, there is an increasing interest in …

The effect of electrical intramuscular stimulation on sub acute and chronic hamstring muscle strain injuries
… treatments modalities for sub acute and chronic hamstring strains. Design: A randomized experimental design was used to compare the effects of low (2 Hz), high (50 Hz) and no-electrical (control) intramuscular stimulation on muscle strength and mental and functional status (AMSMC HEALTH STATUS …
