Study Notes
Cardiovascular Adaptations to Training
- Heart Hypertrophy: Heart walls thicken and strengthen, increasing stroke volume.
- Increased Stroke Volume: More blood pumped per heartbeat.
- Decreased Resting Heart Rate: A result of increased stroke volume.
- Increased Cardiac Output: More blood pumped per minute.
- Increased Red Blood Cells: Improved oxygen delivery to muscles.
- Increased Capillaries (Muscles & Alveoli): Enhanced gaseous exchange (oxygen and carbon dioxide).
- Reduced Lactic Acid Accumulation: More efficient oxygen delivery system.
- Larger, More Elastic Arteries: Improved blood flow.
Respiratory Adaptations to Training
- Strengthened Diaphragm & Intercostal Muscles: Increased lung capacity.
- Larger Lung Volumes: More oxygen intake.
- Increased Alveolar Capillaries: Enhanced oxygen diffusion into the blood.
Muscular Adaptations to Training
- Increased Muscle Bulk: Stronger and more powerful muscles.
- Increased Muscle Strength: Stronger bones and ligaments for injury prevention.
- Increased Mitochondria: More energy production in muscles.
- Increased Myoglobin: Increased oxygen storage in muscles.
- Increased Glycogen Storage: More glucose stored in muscles.
- Increased Lactic Acid Tolerance: Improved performance during exercise.
Heart Rate and Training
- Resting Heart Rate: Average is 72 beats per minute.
- Working Heart Rate: Increases during exercise.
- Recovery Heart Rate: Higher than resting but lower than working allows for replenishment of oxygen debt.
- Training Zone: Maintain heart rate in the target zone for at least 15 minutes.
- Maximum Heart Rate: Calculated as 220 minus age.
- Aerobic Training Threshold: 60-80% of maximum heart rate.
- Anaerobic Training Threshold: 80-90% of maximum heart rate.
