DANCE 3 Lecture Notes - Lecture 4: Myofibril, Harvard Step Test, Hypertrophy
Document Summary
Improving cellular metabolism: regular endurance exercise improves metabolism (metabolic rate) Improves capillaries in muscles: allows training muscles to make the most of oxygen and fuel. Increases mitochondria (powerhouse of the cell: prevents glycogen depletion. Reduced risk of chronic disease: cardiovascular diseases, cancer, type 2 diabetes, osteoporosis, reduced bone mass due to constant sitting or no bloating of the bone/stress on the bones.

Better control of body fat: regular exercise increases daily calorie expenditure, exercise increases resting metabolic rate. Outcome measure: something you are measuring to see if you can find a difference. Neck pulse = carotid pulse: used as an outcome measure for the 3-minute step test.
