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.
