Document Summary

Unnecessary details for the final)!!!!!! (focus on the study guides for special topics instead of studying. Available forms of energy include: atp (aerobic or anaerobic), plasma glucose, glycogen in liver and muscle, gluconeogenesis, and fatty acids for diet/storage. For immediate energy production, phosphagen (phosphocreatine and atp) is used. Long-term energy production is aerobic and gives 1 atp/min for 2 mins and over. Aerobic: krebs, etc, beta-oxidation (fats!) for over 2 minutes! Triglycerides fatty acids (using cortisol, epi/norepi, gh) Regulation of glucose metabolism during exercise: (don"t remember all in detail) Difference between total oxygen used and what would have been used if one had achieved steady state immediately. Exercise intensity results in more dramatic lactate production, which decreases endurance. Less intense exercise allows for longer endurance and a more gradual increase of lactate. Lt is reached at 40-60% of vo2max with sedentary individuals. Lt is reached at >70% of vo2max with trained individuals. Intrinsic: gender, genetic, body comp, muscle, age, pathologies.
