Drinking policies and exercise-associated hyponatraemia: is anyone still promoting overdrinking?
The purpose of this review is to describe the evolution of hydration research and advice on drinking during exercise from published scientific papers, books and non-scientific material (advertisements and magazine contents) and detail how erroneous advice is likely propagated throughout the global sports medicine community. ⋯ Drinking policies during exercise have changed substantially throughout history. Since the mid-1990s, however, there has been an increase in the promotion of overdrinking by athletes. While the scientific community is slowly moving away from "blanket" hydration advice in which one form of advice fits all and towards more modest, individualised, hydration guidelines in which thirst is recognised as the best physiological indicator of each subject's fluid needs during exercise, marketing departments of the global sports drink industry continue to promote overdrinking.

To determine if asymmetry of trunk muscles and deficits of motor control exist among elite cricketers with and without low back pain (LBP). ⋯ This study provides new insights into trunk muscle size and function in elite cricketers, and evidence of impaired motor control in elite cricketers with LBP. Rehabilitation using a motor control approach has been shown to be effective for subjects with LBP, and this may also benefit elite cricketers.

To determine the prevalence and nature of rock-climbing injuries, and the factors associated with these injuries. ⋯ Climbing frequency and technical difficulty are associated with climbing injuries occurring at both indoor and outdoor venues, particularly cumulative trauma to the upper extremities.

To determine the direct and indirect cost of injuries in professional jockeys as a result of race riding. ⋯ Horse racing is a sport known to have a high risk of injury. This study has found that almost 4.5 million pounds sterling was spent on the injuries that were reported to PRIS during the 11-year time period 1996-2006. This study sheds light on the overall injury cost in professional horse racing and will form the basis for more formal health economic analysis.

The anterior cruciate ligament (ACL) has both mechanical and proprioceptive (sensory) functions. Knee-joint proprioception has been assessed using either reproduction of position or threshold to detect passive motion in non-weight-bearing positions. It has been suggested that a more functional and dynamic/active assessment of proprioception might clarify the effects of injury and reconstruction on the proprioceptive function of ACL at the knee joint. ⋯ We found no evidence of impaired JPS in weight-bearing positions in subjects with ACL reconstruction at a mean follow-up of 11 months after surgery compared with subjects with healthy knees.
