How Do Workouts Change the Body? ANAEROBIC AEROBIC Changes Triggered by Aerobic Exercise • Increased aerobic capacity in muscles • Greater mitochondrial density • Increases in myoglobin • More slow twitch muscle fibers • Conversion of Type IIx to Type IIa muscle fibers • Increased fat metabolism enzymes Benefits of Aerobic Workouts • Greater fat burn • Increased aerobic ability and cardiovascular fitness • Improved endurance • Improved recovery after workouts Changes Triggered by Anaerobic Exercise • Greater quantity and increased size of fast twitch muscle fibers • Improved tolerance to lactic acid buildup • Increased levels of ATP, CP, and creatine in muscles • More enzymes for glycolysis • Increased levels of growth hormone and testosterone Benefits of Anaerobic Workouts • Increased muscle power and strength • Increased muscle hypertrophy • Maximized short-term energy availability in muscles • Improved muscle endurance

ANAEROBIC AEROBIC
Changes Triggered by Aerobic Exercise
• Increased aerobic capacity in muscles• Greater mitochondrial density• Increases in myoglobin• More slow twitch muscle fibers• Conversion of Type IIx to Type IIa muscle fibers• Increased fat metabolism enzymes
Benefits of Aerobic Workouts
• Greater fat burn• Increased aerobic ability and cardiovascular fitness• Improved endurance• Improved recovery after workouts
Changes Triggered by Anaerobic Exercise
• Greater quantity and increased size of fast twitch muscle fibers• Improved tolerance to lactic acid buildup• Increased levels of ATP, CP, and creatine in muscles• More enzymes for glycolysis• Increased levels of growth hormone and testosterone
Benefits of Anaerobic Workouts
• Increased muscle power and strength• Increased muscle hypertrophy• Maximized short-term energy availability in muscles• Improved muscle endurance
