Long-term Effects of Exercise
Long-term Effects of Exercise
Cardiovascular System
- Regular exercise leads to increased stroke volume, meaning that the heart pumps more blood per beat.
- The resting heart rate decreases as the heart becomes more efficient.
- Exercise leads to the growth of additional capillaries, a process known as capillarisation. This enables greater transportation of oxygen and removal of waste products.
- The heart, being a muscle, increases in size and strength due to regular exercise, improving overall cardiovascular endurance.
Respiratory System
- Increased lung capacity is a key long-term effect of exercise. The lungs can take in more oxygen and expel more carbon dioxide during each breath.
- The muscles involved in breathing, such as the intercostal muscles and the diaphragm, also become stronger and more efficient.
- Regular exercise also results in an increase in the number of alveoli (tiny air sacs in the lungs), enabling improved gas exchange.
Musculoskeletal System
- Regular exercise leads to increased muscle size and strength. This process is known as muscular hypertrophy.
- There’s an increase in the density of the bones. Exercise stimulates the bone-forming cells, leading to stronger bones and protection against osteoporosis.
- Exercise improves joint flexibility and the range of movement, reducing the risk of joint-related injuries.
- It enhances neuromuscular coordination, meaning improved balance, skill, and motor ability.
Metabolic Changes
- Exercise improves the body’s metabolic rate - the efficiency at which the body burns calories, aiding in weight management.
- Regular physical activity increases the number and size of mitochondria in cells, thereby improving the ability to produce ATP, necessary for muscle contraction.
- Exercise improves the body’s insulin sensitivity and allows better glucose regulation, reducing the risk of type 2 diabetes.
Mental Health
- Exercise causes the release of chemicals in the brain such as endorphins, which generate feelings of happiness and reduce the perception of pain.
- Regular physical activity can improve sleep quality and helps to manage stress.
- Exercise can boost self-confidence and improve overall cognitive function.
