Importance of Exercises in Human Body

Exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, to aid growth and improve strength, prevent aging, develop muscles and the cardiovascular system, hone athletic skills, weight loss or maintenance, improve health, or simply for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health. In terms of health benefits, the amount of recommended exercise depends upon the goal, the type of exercise, and the age of the person. Even doing a small amount of exercise is healthier than doing none.

Classification of Exercises

Aerobic exercise is any physical activity that uses large muscle groups and causes the body to use more oxygen than it would while resting.

  • The goal of aerobic exercise is to increase cardiovascular endurance.
  • Examples of aerobic exercise include running, cycling, swimming, brisk walking, skipping rope, rowing, hiking, dancing, playing tennis, continuous training, and long distance running.

Aerobic exercise provides the following benefits:

  • Improves muscle strength in the lungs, heart, and whole body.
  • Lowers blood pressure.
  • Improves circulation and blood flow in the muscles.
  • Increases the red blood cell count to enhance oxygen transportation.
  • Reduces the risk of diabetes, stroke, and cardiovascular disease (CVD).
  • Improves life expectancy and symptoms for people with coronary artery diseases.
  • Stimulates bone growth and reduces the risk of osteoporosis when at high intensity.
  • Improves sleep hygiene.
  • Enhances stamina by increasing the body’s ability to store energy molecules, such as fats and carbohydrates, within muscle.

Anaerobic exercise, which includes strength and resistance training, can firm, strengthen, and increase muscle mass, as well as improve bone density, balance, and coordination.

  • Examples of strength exercises are push-ups, pull-ups, lunges, squats, bench press.
  • Anaerobic exercise also includes weight training, functional training, eccentric training, interval training, sprinting, and high-intensity interval training which increase short-term muscle strength.

Flexibility exercises stretch and lengthen muscles.

  • Activities such as stretching help to improve joint flexibility and keep muscles limber.
  • The goal is to improve the range of motion which can reduce the chance of injury.

Benefits of Regular Exercising

  1. Exercise has been shown to improve your mood and decrease feelings of depression, anxiety, and stress. It produces changes in the parts of the brain that regulate stress and anxiety. It can also increase brain sensitivity for the hormones serotonin and norepinephrine, which relieve feelings of depression Additionally, exercise can increase the production of endorphins, which are known to help produce positive feelings and reduce the perception of pain. Furthermore, exercise has been shown to reduce stress and improve symptoms of anxiety.
  2. Your body spends energy in three ways: Digesting food, Exercising, Maintaining body functions like your heartbeat and breathing. While dieting, a reduced calorie intake will lower your metabolic rate, which can delay weight loss. On the contrary, regular exercise has been shown to increase your metabolic rate, which can burn more calories to help you lose weight. Additionally, studies have shown that combining aerobic exercise with resistance training can maximize fat loss and muscle mass maintenance, which is essential for keeping the weight off.
  3. Exercise plays a vital role in building and maintaining strong muscles and bones. Activities like weightlifting can stimulate muscle building when paired with adequate protein intake. This is because exercise helps release hormones that promote the ability of your muscles to absorb amino acids. This helps them grow and reduces their breakdown.
  4. Exercise can be a real energy booster for many people, including those with various medical conditions. One older study found that 6 weeks of regular exercise reduced feelings of fatigue for 36 people who had reported persistent fatigue. Furthermore, exercise can significantly increase energy levels for people with chronic fatigue syndrome (CFS) and other serious illnesses.
  5. Your skin can be affected by the amount of oxidative stress in your body. Oxidative stress occurs when the body’s antioxidant defenses cannot completely repair the cell damage caused by compounds known as free radicals. This can damage the structure of the cells and negatively impact your skin.

Proper nutrition is as important to health as exercise. When exercising, it becomes even more important to have a good diet to ensure that the body has the correct ratio of macro-nutrients while providing ample micro-nutrients, in order to aid the body with the recovery process following strenuous exercise. Active recovery is recommended after participating in physical exercise because it removes lactate from the blood more quickly than inactive recovery. Removing lactate from circulation allows for an easy decline in body temperature, which can also benefit the immune system, as an individual may be vulnerable to minor illnesses if the body temperature drops too abruptly after physical exercise. Exercise has an effect on appetite, but whether it increases or decreases appetite varies from individual to individual, and is affected by the intensity and duration of the exercise. Thus, Physical exercise is important for maintaining physical fitness and can contribute to maintaining a healthy weight, regulating the digestive system, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system that will lead to the increase of life expectancy and the overall quality of life.
