Objective: We present a case of a unique pathophysiological injury involving severe dehydration, muscle cramping, and resultant rhabdomyolysis in a high school football player. Background: A 16 y old male football player (body mass = 69.1 kg, height =175.3 cm) reported to the ATC after the morning session on the second day of two-adays complaining of severe muscle pain and cramping. Upon arriva...

Using self-determination theory (Deci & Ryan, 1985) as the theoretical framework, we examined potential antecedents of athlete burnout in 201 elite Canadian athletes (121 females, 80 males; mean age 22.9 years). Employing a cross-sectional design, our primary aims were to investigate the relationships between behavioural regulations and athlete burnout and to examine whether self-determined mot...

Elite athletes endeavour to train and compete even when ill or injured. Their motivation may be intrinsic or due to coach and team pressures. The sports medicine physician plays an important role to risk-manage the health of the competing athlete in partnership with the coach and other members of the support team. The sports medicine physician needs to strike the right ethical and operational b...

W hen an injury forces an athlete out of training and/or competition, the return-to-play (RTP) decision-making process may be simple or multidimensional. When analyzing these situations, an important factor to consider is why the injury occurred in the first place. Was the injury a result of an unavoidable trauma, such as a hit to the knee in a contact sport, or the result of fatigue or poor co...

OBJECTIVE To demonstrate the response to a proprioceptive training model during a 1-week rehabilitation regime. The techniques were demonstrated on a college-aged female basketball player who had injured her anterior cruciate ligament (ACL) several weeks earlier. The athlete was tested, trained, and then retested during her semester break. BACKGROUND The ACL injury has become a fairly common ...

OBJECTIVE To analyze and compare the vertical component of ground reaction forces and isokinetic muscle parameters for plantar flexion and dorsiflexion of the ankle between long-distance runners, triathletes, and nonathletes. METHODS Seventy-five males with a mean age of 30.26 (±6.5) years were divided into three groups: a triathlete group (n=26), a long-distance runner group (n = 23), and a ...

Association studies, comparing elite athletes with sedentary controls, have reported a number of genes that may be related to athlete status. The present study reports the first genome wide linkage scan for athlete status. Subjects were 4488 adult female twins from the TwinsUK Adult Twin Registry (793 monozygotic [MZ] and 1000 dizygotic [DZ] complete twin pairs, and single twins). Athlete statu...
