Exercise and Fitness in Humans

Understanding Exercise and Fitness

  • Exercise refers to any movement that gets your muscles working and requires your body to burn calories.
  • There are many types of exercise, including swimming, running, jogging, walking and dancing.
  • Fitness relates to your body’s ability to function efficiently and effectively in work and leisure activities, resist diseases and respond to emergency situations.

Benefits of Exercise and Fitness

  • Regular participation in physical activity reduces the risk of developing conditions such as heart disease, diabetes, and obesity.
  • Exercise has been shown to improve mental health by reducing symptoms of depression and anxiety.
  • Regular exercise also contributes to enhancing quality of sleep and increasing energy levels.
  • Physical activity strengthens the musculoskeletal system, enhancing bodily movement and posture.

Components of Fitness

  • Aerobic Fitness: Measures the ability of your heart and lungs to deliver blood to your body’s tissues and take away metabolic waste products.
  • Strength: The capacity of a muscle or muscle group to exert force against resistance.
  • Flexibility: Describes the range of movement across a joint, with regular stretching improving overall mobility.
  • Body Composition: Refers to the ratio of body fat to lean body mass.

Impacts of Lack of Exercise

  • Insufficient physical activity can lead to weight gain and obesity.
  • A lack of exercise is also linked to certain types of cancer, such as breast cancer and colon cancer.
  • An inactive lifestyle can also lead to mental health issues such as depression and anxiety.

Importance of Warm Up and Cool Down

  • Warming up helps prepare your body for aerobic activity. A warm-up gradually revs up your cardiovascular system and increases blood flow to your muscles.
  • Cooling down after your workout allows for a gradual recovery of pre-exercise heart rate and blood pressure.

Exercise Plans and Programs

  • An effective exercise program must take into account fitness objectives, available resources, and existing physical capabilities.
  • To maintain physical fitness and health, the NHS recommends that you should aim for at least 150 minutes of moderate physical activity per week.
  • It is also recommended to include strength training exercises at least two days per week.
