In sports, like team handball, fatigue has been associated with an increased risk of anterior cruciate ligament (ACL) injury. While effects of fatigue on muscle function are commonly assessed during maximal isometric voluntary contraction (MVC), such measurements may not relate to the muscle function during match play. The purpose of this study was to investigate the effect of muscle fatigue in...

We examined the effects of a 12-week program of Nordic hamstring exercises (NHE), administered before or after football training, upon eccentric hamstring strength, muscle activity, and architectural adaptations. Amateur soccer players were randomized into three groups. The control group (CON; n=11) undertook core stability exercises, whereas a periodized NHE program was delivered either before...

BACKGROUND AND PURPOSE The sit-and-reach test (SRT) is commonly used to assess flexibility of the spine and length of the hamstring muscles. The purposes of this study were (1) to describe hamstring muscle length as reflected by use of the SRT and the hip joint angle (HJA) in children, (2) to examine the correlation between SRT and HJA measurements, and (3) to examine gender differences for bot...

PURPOSE The purpose of this study was to evaluate the quadriceps and hamstring muscle strength and hamstring-to-quadriceps (HQ) ratio, as well as the relationships of these parameters with dynamic balance, in patients with anterior cruciate ligament (ACL) rupture. MATERIALS AND METHODS We compared 25 patients diagnosed with chronic unilateral ACL tears and 25 age-matched healthy volunteers. T...

The aim of this study was to perform an electromyographic and kinetic comparison of two commonly used hamstring eccentric strengthening exercises: Nordic Curl and Ball Leg Curl. After determining the maximum isometric voluntary contraction of the knee flexors, ten female athletes performed 3 repetitions of both the Nordic Curl and Ball Leg Curl, while knee angular displacement and electromyogra...

[Purpose] Degenerative changes take place in the musculoskeletal system of elderly people, resulting in a reduced range of motion. For this reason, stretch training is recommended for elderly individuals. To date, there have been no studies of the adaptations of the passive properties of muscles following long-term stretch training. The aim of this study is to investigate the hamstring elastici...

OBJECTIVES To use a randomised, double blind, placebo controlled trial to establish the effect on straight leg raise, hip internal rotation, and muscle pain of dry needling treatment to the gluteal muscles in athletes with posterior thigh pain referred from gluteal trigger points. METHODS A randomised, double blind, placebo controlled trial of 59 male runners was performed during the 2002 Aus...

Objective To analyse the rates of lower limb muscle injuries in athletics disciplines requiring different running velocities during international championships. Design Prospective total population study. Methods During 13 championships (2009–2019) national medical teams and local organizing committee physicians daily reported all newly incurred using same study design, injury definition data co...
