Document Summary
Lecture 18 march 19 circadian rhythms in athletic performance. Types of energy supply: with exercise, there are 3 types of energy supply being used . Atp is used (atp stores can be quickly depleted, but also built back up). Cycling uses aerobic (quick bursts of energy) and anaerobic (longer duration, long term energy deficits run out of o2 to be used oxygen needs to be brought back to replenish them) Endurance training involved in cycling bc requires stamina. Strength training used in weight lifting, but cyclists need strong legs to pedal quickly. Metabolism = sum of all catabolic (breakdown of substances during inactive phase to maintain basal energy level. Incl glycolysis, citric acid cycle, cell resp, deamination) and anabolic reactions (building products photosynthesis, gluconeogenesis, lipid synthesis, protein synthesis) Obesity epidemic: obese = bmi bw 30-34. 9, has been increasing (study suggests in 2020, over 50% of adults in canada expected to be overweight).
