BACKGROUND The hamstring injury mechanism was assessed by investigating the exercise-related metabolic activity characteristics of the hamstring muscles using a muscle functional MRI (mfMRI) protocol. METHODS 27 healthy male football players and 27 football players with a history of hamstring injuries (recovered and playing fully) underwent standardised mfMR Imaging. The mfMRI protocol consis...
New studies in neuromuscular control have indicated that the strength of muscle contraction isn’t the only important factor in a task. But the speed at which a muscle responds, preparation of muscle and synergistic pattern at which a group of muscles recruit to a task or respond to a condition are much more important in constant joint stabilization and potential injury prevention. The purpo...
Introduction: Consequence of incorrect body posture are investigable in physical, psychical, economical and social aspects. The study of the corrective exercise during 8 weeks on hyperlordosis girl students of Shahid Bahonar university of Kerman was the main purpose of the present study. Methods: Subjects consist of 24 hyperlordosis girl students of Kerman Bahonar University. They were randomly...
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...
OBJECTIVE To determine the relation of hamstring and quadriceps muscle strength and imbalance to hamstring injury using a prospective observational cohort study METHOD A total of 102 senior male Australian Rules footballers aged 22.2 (3.6) years were tested at the start of a football season. Maximum voluntary concentric and eccentric torque of the hamstring and quadriceps muscles of both legs...
Of the hamstring muscle group the biceps femoris muscle is the most commonly injured muscle in sports requiring interval sprinting. The reason for this observation is unknown. The objective of this study was to calculate the forces of all three hamstring muscles, relative to each other, during a lengthening contraction to assess for any differences that may help explain the biceps femoris predi...
OBJECTIVES To assess in a single team of Australian Rules football players the effect of a specific intervention program on the incidence and consequence of hamstring muscle strain injuries. METHOD A prospective study was performed with a single team being followed for four playing seasons for hamstring injury. Magnetic resonance imaging was used to confirm the diagnosis of hamstring muscle i...
CONTEXT Preventing noncontact ACL injuries has been a major focus of athletic trainers and researchers. One factor that may influence female noncontact ACL injury is the fluctuating concentrations of hormones in the body. OBJECTIVE To determine whether muscle properties change across the menstrual cycle. DESIGN Repeated measures. Testing was performed within 3 d after the onset of menses an...
Background and Aim: Only a few studies have been conducted to investigate the effect of ultrasound and duration of stretching on the enhancement of hamstring muscle flexibility. The purpose of this study was to determine the knee joint passive extension in male students with hamstring shortness and the effect of duration of stretching and ultrasound on the treatment of this deficit. Materials ...
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...
