Physically active men and woman may be less likely than their inactive peers to become overweight. Exercise has a favourable effect on body fat distribution, with a reduction in waist-to-hip ratio with increased exercise. Exercise is especially important in maintaining weight loss in overweight individuals. Physical activity can directly affect both total energy intake and total energy expenditure. Physical activity can also affect fat balance and it is becoming clear that imbalances in total energy are largely due to imbalances in the distribution of fat. Exercise also has additional, beneficial effects on most of the metabolic risk factors for cardiovascular disease and non-insulin dependent diabetes mellitus. Exercise testing provides a basis for the design of training programs and allows for monitoring progress throughout the training program. Used properly, testing and monitoring is useful to both trainers and subjects. Therefore, exercise in conjunction with an appropriate diet is beneficial to overweight individuals and provided that feasible methods and motivation are available, we recommend exercise as an important part of a weight control program. The aim of this study was to determine whether HMB supplementation will increase the Lean Body Mass (LBM) and muscle power output (measured as the load a subject can bench press) of males who gym for recreational purposes, after a combination of resistance weight training, eating a balanced set diet and supplementation with HMB for 8 weeks. Two homogenous groups of 20 males were evaluated for initial strength capabilities and body composition. For 8 weeks the subjects lifted weights three times a week and followed a balanced diet. Creatinekinase activity decreased with HMB supplementation. Gains in muscle power output were greater in the experimental group, and fat percentage decreases were recorded with HMB supplementation. / Dissertation (MSc)--University of Pretoria, 2011. / Physiology / unrestricted
