Endurance training prescriptions are often based on laboratory measurements of physiological reference points, such as the ventilatory threshold (VT). This study evaluated the relationship between a simple surrogate of the VT, the Talk Test (TT), and objective measures of VT in well-trained individuals. This was a comparative study of the oxygen consumption (V02) in reference to TT, VT and respiratory compensation threshold (RCT).
This research examined the psychological preparation of elite (national and provincial) South African athletes to determine the quantity and quality of sport psychology techniques in use. Design. Sportsmen and women (N = 30) from a variety of athletic disciplines either completed an appropriate questionnaire (N = 15) or agreed to be interviewed (N = 15) to determine which sport psychology skills they were using and/or felt were useful.
There are no data available on pre-season medical profiles, previous injuries and management, use of medication and supplements, or use of protective gear in professional rugby players playing in the Super 12 Rugby competition. The objection of this paper is to descriptionbe the use of medication and nutritional supplements, previous injuries, possible risk factors for injury, and use of protective gear in a cohort of professional rugby players.
The aim of the study was to obtain test-retest indications on the Standardised Assessment of Concussion (SAC) screening test and the verbal fluency tasks in a South African non-concussed rugby-playing population. A second aim was the preliminary application of these test-retest data to one concussed player. All investigations were carried out at the Department of Speech Pathology and Audiology at the University of the Witwatersrand, Johannesburg. The study utilised a longitudinal quasi-experimental design on a group of self selected rugby players from various rugby teams in Gauteng.
This study considered mean skin temperature (Tmsk), forehead temperature (Tfor) responses and estimated sweat losses including absolute (SLabs), relative (SLrel), absolute rate (SRabs) and relative rate (SRrel) while batting during simulated cricket activity. The purpose was to determine the effect of protective gear on skin temperature responses and fluid loss.
A fall onto the shoulder during cycling can cause an often unrecognised fracture of the greater tuberosity of the humerus, which leads to the following question: What are the optimal studies required to detect subtle fractures of the greater tuberosity? The case subject was a 55-year-old cyclist presented with symptoms of shoulder pain and dysfunction after a cycle fall. The patient was able to continue cycling immediately after the fall. There was no history of a subluxation or dislocation. On examination there was very limited range of movement and tenderness over the anterolateral aspect of the head of the humerus.
