The main difference between the athletes diet and the diet of the general population can be found in the level of energy intake. Energy requirements of the athlete depend not only on the type of exercise, but also on the time used performing the activity.
Like most marathoners, I am an obsessional urine watcher, an avid follower of the effects of running, climate, and a host of other minutiae on the production of this critical human endproduct. And, in common with most runners, my concern is never greater than when this process has been most threatened ï¿½ by those three hours of critical renal insult imposed by the marathon race.
The sports world has experienced the ""fitness boom"" over the past decade. The resultant numer of participants has increased and so has the injuries. This has changed the sports medicals' approach to injury problems. Increasingly, more attention is given to the prevention of injuries and rehabilitation in stead of acute injuries.
Objectives: This study analyzed heart rate, blood lactate and motion patterns of South African (SA) and Overseas (OS) professional beach volleyball players. Methods: Thirty two subjects participating in the World Beach Series, Cape Town, 1995, volunteered with written informed consent (SA=20; OS=12).
The nmemonic ICE (ice: compression: elevation) is well known in sports medicine circles and has served us well. In order to treat an acute sports injury, a more comprehensive programme than simply ICE is necessary. REACT is suggested as an advance on the old ice; compression and elevation.
The purpose of this study was to investigate hamstring /quadricep strength ratios in long distance runners and sprinters. Hamstring /quadriceps strength ratios were obtained in twenty five elite long distance runners and twenty one sprinters at a testing speed of 60 degrees /sec on the Cybex II. Hamstrings were found to be 62% and 59% of quadriceps in sprinters and long distance runners respectively. Sprinters generated significantly greater knee flexor and extensor muscle torque than long distance runners for both legs even when strength was expressed relative to body weight.
Objectives: This study assessed the heart rate (HR) responses recorded every 15 seconds, of ten umpires (six provincial and four international umpires) to onfield events during limited-overs' cricket matches. Methods: Specific on-field events, including appeals, the umpires resulting decisions and any other tasks the umpire had to make such as calling a no-ball or a wide-ball, were recorded.
Objectives : To assess the choice of surgical repair procedures and post-operative management of the ruptured Anterior Cruciate Ligament (ACL) in the South African Orthopaedic community. Methods : A census questionnaire study was conducted on all 475 Orthopaedic surgeons registered with the Orthopaedic Association of South Africa during 1993/1994. The Chi-square test was used to determine statistical significance between different groups of respondents.
