A 12 week pre-season fitnes training programme for senior male high school rugby players : the effect of supervision on anthropometric, physiological and physical performance variables

Author: Clark, David Rodney Date: 1998 The study comprises of two sections; i) a survey to determine the attitude towards fitness training for rugby and the current fitness training habits of elite high school rugby players in their penultimate year at school, ii) a training study ... Read more
Accuracy of the prediction of Ironman performance : relationship to training history, muscle pain and relative perception of effort during, and recovery after the race

Author: Spijkerman, Ronel Date: 2010 With regards to swimming, cycling and running, several studies have investigated the physiological and genetic contribution of performance in athletes, different training programs and athletes' adaptation to these programs. Other studies have ... Read more
Achilles tendon ultrasound findings in triathletes before and after the ironman triathlon

Author: Schwabe, Karen Date: 2006 The aim of this prospective cohort study therefoew was to assess the morphological and blood flow changes in the Achille tendons of triathletes competing in the 2006 South African Ironman Triathlon. Read more
An assessment of muscle insertion sites and biomechanical beam analaysis in living subjects

Author: Sanders, Virginia M Date: 2001 The main aim of this study is to examine the gross morphology of the radial tuberosity, brachialis insertion site and supinator crest in living subjects, and to correlate this with muscle strength. Read more
The association of the AVPR2 gene with serum sodium and water imbalances during an Ironman Triathlon

Author: Ah Kun, Maresa Date: 2007 It is well documented that participation in ultra-endurance events such as the Ironman Triathlon, can be associated with the development of post-race water and sodium imbalances in athletes. Variants within genes that encode for proteins that ... Read more
Biochemical changes in athletes during marathon and ultra-marathon races, with special reference to the incidence and prevention of hypoglycaemia

Author: McArthur, Penelope S Date: 1984 Fats and carbohydrates are the major fuels utilized during exercise and it has been suggested that carbohydrate depletion is the cause of exhaustion during prolonged exercise lasting more than two hours. However, there is some disagreement ... Read more
Blood lactate levels during exercise : the effects of exercise duration, bicarbonate infusion and beta-receptor antagonism

Author: Bertram, Sheila Rae Date: 1985 This study examines factors that determine blood lactate accumulation during exercise in order to examine the opposing theories that such accumulation occurs either as a result of muscle anaerobiosis or an "overflow" of oxygen-independent glycolysis. Read more
Body composition and physical performance characteristics of elite senior and U19 South African rugby union players

Author: Scales, Nicola Date: 2000 Bibliography: leaves 126-134. Read more
Body size, socioeconomic status and training background of a select group of U16 South African rugby union players (2010-2013): The impact on national selection

Author: Arkell, Robin Date: 2016 Background: Rugby Union is an international sport characterized by bouts of short duration, high intensity exercise in which players frequently collide into one another while running at high speeds. Players are commonly required to engage in ... Read more
Carbohydrate metabolism during active and passive post-exercise recovery

Author: Peters, Edith M Date: 1984 It is known that light muscular activity performed during the immediate post-exercise recovery period, increases the rate at which lactate and protons are removed from the circulation. This study examined the effect which this light activity ... Read more
Circadian rhythm, activity level, training habits and sports performance : the molecular and subjective components

Author: Stephenson, Kim Jenna Date: 2013 Circadian rhythmicity, which is driven by a circadian clock, is a property of a biological process that displays an oscillation of approximately 24-hours even in the absence of external time cues. Individual differences in the preferred times ... Read more
Clinical and immunological factors associated with post-race upper respiratory tract symptoms (URTS) in Ironman triathletes

Author: Baxter, Peter Date: 2007 Ultra-endurance events, in particular Ironman Triathlons, are physically very demanding for the competitors. There is a large body of evidence showing the Upper Respitory Tract Symptoms (URTS) are very common in athletes in the 2-week period ... Read more
Coaches' perception of catastrophic injuries risks in South African Rugby Union : A qualitative exploration through a socio-ecological lens

Author: Joshua, Jonathan Date: 2017 Introduction: The annual rate of rugby-related catastrophic injuries (CIs) in South Africa has been classified as "acceptable". However, of all injuries, CIs are the most traumatic for all involved. Therefore, the BokSmart programme was ... Read more
Comparative effects of calcium channel antagonism and beta-1 selective blockade on exercise performance in physically active hypertensive patients

Author: Selvey, Christine Enid Date: 1997 The current recommendations by the American Heart Association for health promotion are that all persons should partake in regular physical activity in order to reduce the risk of cardiovascular disease. Regular physical exercise reduces blood ... Read more
A comparison of two treatment protocols in the management of exercise-associated postural hypotension (EAPH) : a randomised clinical trial

Author: Anley, Cameron Date: 2007 The aim of this study was to compare which of the two commonly used treatment protocols for Exercise Associated Postural Hypotension (EAPH) (Trendelenburg with oral fluids ad libitum or intravenous fluids) result in quicker recovery and earlier ... Read more
Current practices in cardiac rehabilitation : implications for scope of rehabilitation and assessment of functional capacity

Author: Dreyer, Liezel Ann Date: 2004 Bibliography: leaves 93-106. Read more
Determinants of body composition changes over 5.5 years and the associated cardio-metabolic risk factors in free-living black South African women

Author: Chantler, Sarah Date: 2014 Research from both developed and developing countries, including South Africa (SA), has shown that black women experience a disproportionately high burden of obesity and associated non-communicable diseases compared to their white counterparts. ... Read more
Development of a functional neuromuscular stimulation (FNS) muscle training program to prepare paraplegics for standing

Author: Schafer, Carol Linda Date: 1989 Wheelchair-bound paraplegics are in an unnatural, almost all-day sitting position. This is physiologically disadvantageous as it may cause increased abdominal pressure, renal dysfunction, pressure sores, muscle atrophy and osteoporosis. Thus ... Read more
The effect of anabolic-androgenic hormones on postprandial triglyceridaemia and lipoprotein profiles in man

Author: Hislop, Michael Stuart Date: 1997 It has been hypothesised that endogenous testosterone and AAS may predispose humans to premature CHD. However, there is no direct evidence to link these hormones with a greater prevalence of premature CHD. The aim of this thesis was to better ... Read more
The effect of branched-chain amino acid ingestion on physical performance during prolonged exercise

Author: Velloza, Peter Edward Date: 1996 It has been hypothesized that an increase in the ratio of plasma tryptophan (TRP) to branched-chain amino acid (BCAA) concentrations may mediate an increase in cerebral serotonin synthesis, through an increased cerebral tryptophan uptake. It ... Read more
