Document Summary

Physical fitness: ability to perform moderate to vigorous activity without undue fatigue. Reduce the number of adults engaging in no leisure physical activity by 10% Increase the number of adults who engage in aerobic physical activity of moderate & vigorous intensity. Increase the number of adults who perform muscular-strengthening activities. Focus on long-term and not on occasional setbacks. Aerobic activity that increases heart rate and breathing (5-6 on rpe scale) Aerobic activity that greatly increases heart rate and breathing (7-8 rpe. Activity that increases skeletal muscle strength, power, endurance, and mass. Only small amount is stored in resting cells. High energy compound formed & stored in muscle cells. Metabolic pathway that converts glucose to pyruvate, then to atp. Produces 2 atp per glucose 5% of energy potential. Cannot sustain atp production 30 seconds-2 minutes of work. Produces 28-30 atp per glucose 95% of energy potential. Temporary storage of glucose in liver and muscle.
