Psychological rehabilitation from sport injury: issues in training and development of chartered physiotherapists
… psychological rehabilitation to athletes during sport injury, very little research exists outside North America, Australia, and New Zealand (e.g., Hemmings & Povey, 2002). Thus, the main purpose of this research was to explore the role of UK chartered physiotherapists in the process of …

Coaches' perception of catastrophic injuries risks in South African Rugby Union : A qualitative exploration through a socio-ecological lens
… variations in socio-economic statuses (SES) of sport participants. In addition, individuals are known to accept perceived levels of risks and ignore the actual levels of risks. Thus, rugby policy makers, experts, coaches and players may have conflicting views regarding CIs risks associated with …

Respiratory health of the endurance athlete : prevalence of respiratory related conditions/illnesses in endurance athletes
Background: Endurance athletes, in particular triathletes and ultra-distance runners, undergo high volumes of intense training in preparation for events. There is recent epidemiological evidence that the respiratory tract is the most common system affected by illness in athletes during tournaments. …

Factors limiting the exercise tolerance of patients with end-stage renal failure undergoing maintenance haemodialysis
Exercise tolerance, measured as peak oxygen consumption (VO₂ peak), is very low in patients with end-stage renal failure undergoing maintenance haemodialysis. Due to their associated anaemia and low peak heart rates during maximal exercise it has been argued that the reduced blood oxygen carrying …

Physiological and metabolic responses to constant and variable load cycling performance
The experiments described in this thesis comprise a series of related, yet independent investigations examining the physiological and metabolic responses of well-trained amateur cyclists under conditions designed to mimic actual competitive situations, during individual and mass start races. In …

Upper respiratory tract symptoms and allergies in Ironman triathletes
… but there is evidence form other endurance sports that symptoms of respiratory tract infection are particularly common. However, the prevalence, causes and consequences of these symptoms have not been studied in Ironman triathletes. The aims of this study were: 1) to determine the incidence …

An electrophysiological study of ion transport across the isolated perfused malpighian tubule of Onymacris plana
… is fundamental to the understanding of the transport mechanisms of fluid across the basolateral and apical membranes. Until now no one has investigated the isolated perfused Malpighian tubule of Onymacris plana and simultaneously measured basolateral potentials. Malpighian tubule segments (about …

Exercise-induced protection against insulin resistance and type 11 diabetes : the role of calcium
… content of the insulin-regulatable glucose transporter (GLUT4) in skeletal muscle (84). Understanding the mechanisms by which exercise increases GLUT4 levels in skeletal muscle may reveal targets for pharmaceuticals to treat insulin resistance and type II diabetes. Although in vitro binding …

The effects of amlodipine on exercise performance in mild to moderate essential hypertensives
The effect of the long acting dihydropyridine calcium channel antagonist, amlodipine, on the exercise performance of hypertensive patients is not known. The aim of this study was to determine the effects of amlodipine on maximal (MAX), prolonged submaximal (PSX) and on skeletal muscle function …

Endogenous glucose production and gluconeogenesis during exercise in athletes on either a low-carbohydrate or mixed diet
INTRODUCTION. The LCHF diet produces major changes in whole-body substrate metabolism and energy stores such as reduced muscle and liver glycogen content, increased rates of fat oxidation and decreased rates of carbohydrate (CHO) oxidation. Despite reduced CHO availability, the rate of CHO …

Carbohydrate metabolism during active and passive post-exercise recovery
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 had on muscle glycogen and lactate levels, as well as the …

Secular changes in anthropometric and physical characteristics of South African National U/20 rugby union players (1998-2010).
The aim of this study was to compare changes in the physical and morphological characteristics of South Africa’s National U/20 rugby union players (Forwards and Backs) over a 12 year period from 1998 - 2010. This period spans an era starting just after the onset of professionalism of the game to …

Metabolic and lifestyle profiling of overweight female runners compared to lean counterparts: exploring the implications and causes of their elevated body weight
There appears to be an emerging phenotype of recreational runners who are overweight despite being regularly active. This conflicts with the common perception that exercise protects against weight-gain, and it may be caused by underlying insulin-resistance. Alternatively, recent research has …
