Insulin and glucagon (don’t worry about somatostatin) For each hormone know: * it’s function/action * the effect that exercise has on it * Table 5.2 is a good starting point to organize your studying, but refer to notes for further details Hormonal control of substrate utilization Focal point of hormonal control…MAINTAIN BLOOD GLUCOSE (know the 4 processes) Hormonal response to ex and fasting in an effort to maintain blood gluc homeostasis Insulin, glucagon and SNS effects on each Changes of these during exercise and when trained Slow- vs. fast-acting hormones Thyroxine, cortisol, growth hormone, catecholamines, insulin, glucagon and how they control blood gluc during ex SNS effect on insulin and glucagon when blood gluc is constant during ex Changes of all during exercise and when trained TEMPERATURE REGULATION – Ch. 12 & 24 Purpose of heat balance Normal core temp and methods for maintenance How exercise challenges temp homeostasis and how body regulates Hypothalamus control over temp regulation (anterior vs. posterior) Heat production (voluntary vs. involuntary) 4 processes for heat loss - - KNOW THESE Factors that affect evaporation rate - - KNOW THIS Heat storage during ex Head index Ex in heat (sweat rate, core temp) Cause of heat injury and symptoms Prevention guidelines Hydration/Prevention of dehydration Causes of impaired performance in hot environment Heat acclimatization Artificial heat training Ex in cold Hypothermia and contributing factors Water immersion (effects on temp changes) Insulating
