Question: A performance related nutritional strategy for a professional rugby league player.

Answer: Nutritional strategies are an integral component of the overall goal of improving athletic performance. The amount, composition and timing of food and fluid intake can profoundly affect sports performance. Good nutritional practice will help athletes train hard, recover quickly and adapt more effectively with less risk of illness and injury.......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: To what extent can autoimmunity be described as the breakdown of self tolerance and how far have animal models contributed to our understanding of human autoimmune disease?

Answer: Autoimmunity is the propagation of adaptive immunity specific for self antigens. The obligation of preventing such an occurrence was recognised by Ehrlich who described the possibility of ‘Horror autotoxicus’. In his ‘clonal selection’ theory, Burnet proposed that tolerance to self antigens is achieved by clonal deletion or inactivation of developing......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: The metabolic response to pre-exercise glucose ingestion during running.

Answer: Conflicting reports have been reported regarding the metabolic effects of carbohydrate feeding prior to exercise. Although ingestion of a carbohydrate-rich meal 3-4 h before exercise has been shown to increase muscle glycogen (Coyle et al., 1985) and enhance exercise performance (Sherman et al., 1989: Wright et al., 1991: Schabort et al., 1999), there is a widely held view that consuming any carbo......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: Glycogen Resynthesis After Exercise

Answer: Ingestion of carbohydrates following exercise is associated with a series of metabolic events which result in resynthesis of glycogen in skeletal muscle. In contrast to the rapid depletion of stored carbohydrates which takes place in skeletal muscle during brief bouts of heavy or prolonged exercise, the complete restoration of muscle glycogen to pre-exercise levels in glycogen depleted muscle may ......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: Carbohydrates and Endurance in Athletes

Answer: Carbohydrates and lipids are the main energy sources for endurance exercise. The contribution of proteins, while more than minimal, do not exceed 10%. The choice of substrate used during exercise is a metabolic compromise. Carbohydrates are an attractive fuel for muscular work. ATP mole output from carbohydrates per litre of oxygen consumed is higher than for lipids. However, liver and muscle carb......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: Nutrition and Sport

Answer: Evidence from research studies suggests that, while athletes generally consume a greater number of kcalories than non-athletes, they follow patterns of carbohydrate, fat, and protein intake similar to those of non-athletes (1). This means that, in general, athletes consume too much fat and too little carbohydrate, particularly complex carbohydrate. Both male and female athletes are reported to con......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: Glucose Metabolism In Skeletal Muscle

Answer: Skeletal muscle plays a central role in the regulation of whole body glucose metabolism. By virtue of its mass, skeletal muscle is the primary tissue responsible for insulin-dependent glucose clearance, accounting for up to 80% of whole-body glucose uptake. Under fasting conditions, when insulin is low, muscle accounts for less than 10% of whole-body glucose uptake, as the central nervous system b......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: DISSERTATION: THE AETIOLOGY OF INJURIES SUSTAINED BY THE UNIVERSITY OF WALES INSTITUTE, CARDIFF (UWIC) MEN’S AND WOMEN’S COLLEGIATE SOCCER TEAMS, WITH A VIEW TO PREVENTION.

Answer: The purpose of the study was to extend previous research into injuries sustained by male and female soccer players. The study aimed to examine the aetiology, location, extent/severity, and incidence of injuries sustained by male and female collegiate soccer players in matches, team and individual training sessions. From these findings the author was then able to establish preventative measures. Th......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay

Question: Design a preparation phase plan for a sport of your choice which focuses on areas of physical preparation and conditioning fitness.

Answer: Before an athlete begins a training programme, the components of fitness for the specific sport that they are training for must be understood. In hockey there are many components of fitness but the main ones are listed in the table below. The components in the table must be included in any programme to ensure that the training is effective.......(short extract) to download the full answer, please Sign in or Register then make a payment or submit an essay
