Muscular strength is an important factor which is crucial for performance and injury prevention in most sports. The purpose of this study was to evaluate the effects of the FIFA's Medical Assessment and Research Centre 11+ and HarmoKnee injury prevention programs on knee strength of young professional male soccer players. Thirty-six soccer players (age: 18.9 ± 1.4 years) were divided equally in...

The purpose was to test the effect of eccentric strength training and flexibility training on the incidence of hamstring strains in soccer. Hamstring strains and player exposure were registered prospectively during four consecutive soccer seasons (1999-2002) for 17-30 elite soccer teams from Iceland and Norway. The first two seasons were used as baseline, while intervention programs consisting ...

background hamstring muscles play an important role in functional activities and relaxation and most people around the world suffer from the shortened muscles. different methods of repairing were suggested and there were disagreements with regard to determination of one technique with high efficiency. objectives this study aimed to introduce more effective method, either a static stretch or hol...

Objectives: To re-investigate the effect of a cervical isometric contract-relax technique on hamstring extensibility and examine the duration of any treatment effect.Methods: Forty asymptomatic participants were randomly assigned equally to either an experimental or control group. Both groups underwent pre and post hamstring extensibility measurements using passive knee extension with the thigh...

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...

The purpose of the present study was to examine the incidence rates of acute hamstring injuries in Danish elite football sustained during training or match play. Furthermore, it was our intention to document details about the recurrence, severity and the injury seasonal distribution. Hamstring injuries among 374 elite football players were registered prospectively during a 12-month period. A to...

BACKGROUND Proximal hamstring tendinopathy is an uncommon but debilitating cause of posterior thigh pain in athletes subjected to repetitive eccentric hamstring contraction, such as runners. Minimal data exist evaluating treatment options for proximal hamstring tendinopathy. PURPOSE This retrospective study evaluates the effectiveness of fluoroscopically guided corticosteroid injections in tr...

regarding the importance of sciatic nerve distribution in replacement of anal sphincter and sciatic nerve block we decided to study this matter for the first time in iran. in this way 100 cadavers (88% male and 12% female) were dissected and studied by loop microscope. the results shows that primarily, according to the first branch derived from sciatic; there would be 4 main groups. if this sam...

The aim of this study was to determine acute effects of hamstring stretching in thoracic and lumbar spinal curvatures and pelvic tilt. Fifty-five adults (29.24 ± 7.41 years) were recruited for this study. Subjects performed a hamstring stretching protocol consisting of four exercises. The session consisted of 3 sets of each exercise and subjects held the position for 20 seconds with a 30-second...

BACKGROUND The relationship between one-leg static standing balance (OLSSB) and patellofemoral pain syndrome (PFPS) is unknown. HYPOTHESIS OLSSB decreases in patients with PFPS. DESIGN Prospective case series. METHODS Fifty-two women with unilateral PFPS were enrolled in this study. OLSSB was evaluated with a stabilometer. Q angle was measured with a lengthened-arm universal goniometer. L...
