Document Summary

Directly stimulates lipolysis fat metabolism by increasing synthesis of lipolytic enzymes. Increased gh-concentration during aerobic & resistance exercises. Increases in proportion to the exercise intensity. Typically remains elevated for some time after exercise. Increase metabolic rate of almost all tissues. Increase size and # of mitochondria in most cells. Enhance lipid mobilization increase ffa-availability for oxidation. Acute exercise increases tsh-release stimulates release of t3 & t4. Delay between increased tsh during exercise & increased plasma t4- concentration. Prolonged submaximal exercise sharp increase in plasma t4-concentration. T4-concentration remains constant while t3-concentrations tend to decrease over time. Increased glycogenolysis breakdown: glycogen glucose in the liver and muscle. Increased release of glucose & ffas into the blood. Release of these hormones is affected by: Increased exercise intensity > 60-70% vo2max increased epinephrine. Increased exercise intensity > 50% vo2max increased norepinephrine. Essential for adaptive to exercising & other forms of stress. Increases mobilization o ffas increased availability as an energy source.
