HES 250 Lecture Notes - Lecture 11: Pyruvic Acid, Adipose Tissue, Acetyl Group
Document Summary
Total cho: 674 g, total kcal: 3,972. Fat utilization lipolysis forming fatty acids transport by the blood to the muscle transport across mitochondrial membraine within muscle cell. Lipolysis (in adipose tissue) triglycerides glucagon, corticosteroids, acth, catecholamines lipolysis (hormone senstitive lipase) lactic acid insulin (3) nefa + glycerol. Lactic acid and insulin inhibit lipase (which is why you need moderate, not high, intensity to burn fat) Fat loading a dietary manipulation to utilize an alternative, more concentrated fuel source to save carbohydrate stores and/or to slow down the rate of carbohydrate use during exercise. Food choices: butter, jam, eggs, fried meats, mayonnaise, milk chocolate, pastries with whipped cream. Randle cycle a metabolic process involving the competition of glucose and fatty acids for. Research findings: fat utilization was higher with the fat loading trail, but time-trial performance remains indifferent (so use carbo loading).
