This interest and the knowledge he gained from his research led to a major review on the quantification of endurance exercise training programs published in Exercise and Sports Sciences Reviews in 1973. His research at the institute on both endurance and resistance training significantly contributed to the integration of resistance exercise into exercise programs designed to promote health and the development of circuit training regimens. Mike continued his cardiac rehabilitation research ...
The main factor influencing the extent of acute changes to triglycerides and HDL is the amount of energy expended during the exercise session, irrespective of exercise intensity. However, there appears to be little cumulative effect of repeated daily sessions of exercise on LPL activity, explaining why the decrease in triglycerides is essentially an acute effect of exercise that dissipates within 24 h. Prior exercise has such a clear effect on postprandial triglycerides that this model has ...
However, while the experts agree that an increase in physical activity is associated with a lower prevalence of obesity, precisely how much physical activity is required to prevent age-related weight gain is the subject of considerable debate. Although 30 min of daily physical activity may prevent unhealthy weight gain in some individuals, it is now generally reported that this volume of physical activity may be insufficient for the prevention of the age-related weight gain in many if not ...
Find more of the latest research on the relationship between physical activity, sedentarism, and health in Physical Activity and Health, Second Edition. Twin studies, as well as studies in nuclear and extended families, have provided maximal heritability estimates ranging from 15% to 60% for total physical activity level as well as for sedentarism, leisure-time activity, and sport participation. The 2007 update of the Human Gene Map for Performance and Health-Related Fitness Phenotypes ...
Find more of the latest research on the relationship between physical activity, sedentarism, and health in Physical Activity and Health, Second Edition. During the same period in which exercise scientists were systematically studying endurance exercise training and its impact on cardiorespiratory fitness in healthy adults, cardiologists and clinical exercise physiologists were studying the effects of exercise training in patients with cardiovascular disease. As discussed previously, the ...
To maintain whole-body glucose homeostasis, coordination of three different metabolic events is required: adequate secretion of insulin by pancreatic b-cells, suppression of hepatic glucose production, and stimulation of glucose uptake by insulin-sensitive tissues, primarily muscle. Three potential rate-controlling steps and molecules for insulin-stimulated muscle glucose metabolism (i.e., synthesis of glycogen from glucose) have been identified: glucose transporter 4 (GLUT4), hexokinase, ...
