A common soft tissue injury in sports involving sprinting and jumping is the hamstring strain. A major problem with hamstring strains is the high incidence of reinjury. Muscle injuries can be classified as direct or indirect and are typically grouped into three categories according to severity. A number of potential risk factors have been proposed for hamstring strains. Only a few are evidence ...

Muscle fatigue has been defined as “any reduction in the force generating capacity of the total neuromuscular system regardless of the force required in any given situation” (Bigland-Ritchie and Woods, 1984). A reliable muscle fatigue measure has subtly emerged during maximal effort isokinetic contractions that has been able to highlight gender differences in quadriceps and hamstring torque gen...

The purpose of this study was to determine the appropriateness of using an elastic hamstring assistance device to reduce perceived levels of soreness, increase isometric strength, increase passive range of motion, and decrease biomarkers of muscle damage after eccentric exercise, specifically, downhill running This study was conducted in a university exercise physiology laboratory placing sixte...

Background: Hamstring injuries are common in sports that involve rapid, forceful lengthening of the hamstring muscles, such as sprinting, jumping, and kicking. This type injury is more likely to occur team football handball. Objectives: The purpose this study was investigate chronic effects proprioceptive neuromuscular facilitation (PNF) stretching on muscle strength activity muscle. Methods: S...

BACKGROUND To effectively prevent injury in recreational alpine skiing, it is important to identify modifiable risk factors that can be targeted through exercise and training. Fatigue is a potential risk factor in recreational skiing, but no investigations have evaluated concentric/eccentric quadriceps and hamstring fatigue in recreational skiers. We tested the hypothesis that recreational skii...

Hamstring muscle injuries are frequent in different sports and are a clinical challenge for Sports Medicine Teams. Injury Mechanics are import to know while assessing the injured athlete. There are at least two distinctly different types of acute hamstring injuries, which are best distinguished by the different injury situations. Classifying the severity of the injury is equally important. Acti...

[Purpose] This study investigated the effects of inclined treadmill walking on pelvic anterior tilt angle, hamstring muscle length, and back muscle endurance of seated workers with flat-back syndrome. [Subjects] Eight seated workers with flat-back syndrome who complained of low-back pain in the L3-5 region participated in this study. [Methods] The subjects performed a walking exercise on a 30° ...

After anterior cruciate ligament (ACL) reconstruction, which muscle groups are more affected from frequently developing thigh muscle atrophy is a matter of debate. We evaluate the effect of thigh circumference difference between patients' knees who were administered the ACL reconstruction with hamstring tendon autograft and intact knees, on torque between the hamstring and quadriceps muscles. F...
