  What Are The Three Essential Components Of Fitness?

A helpful - and healthful - approach to conditioning is to look at the three essential components of fitness:

  • Cardiovascular health refers to the condition of a person's heart and blood vessels from aerobic conditioning.
  • Flexibility is gained by increasing the range of motion of the joints and muscles in the body.
  • Strength comes from training the muscles over time.

Exercises that strengthen the heart are called "aerobic" exercises. This kind of exercise increases the heart's power and efficiency and improves the body's use of oxygen. Typical aerobic exercises include brisk walking, running, swimming and cycling. All these aerobic exercises should be performed for 20 to 30 minutes at a pace that is brisk but does not make you short of breath.

The most effective way to increase the body's flexibility is to do regular stretching exercises. This kind of exercise can improve the body's range of motion within a relatively short time. Remember to stretch slowly, without bouncing, holding each stretch for at least 10 seconds.

Muscle strength can be improved by forcing the muscles to work against increasing amounts of resistance. The most common methods of building muscle strength are lifting weights and using specially designed resistance machines. Work up to three sets of 10 repetitions each, resting between sets.

Remember; never start an exercise or nutrition plan without first consulting with your healthcare provider to make sure that any changes are compatible with existing health or medical concerns.


 
  What Are The Basic Components (The 4 Factors) Of A Fitness Plan?

  • Aerobic exercise: Since the heart itself is a muscle, aerobic exercise maintains and increases the heart's strength and endurance. When done correctly, such exercise helps the heart reach and maintain a target heart range (THR) for 20 to 30 minutes.
  • Flexibility: The most effective way to increase the body's flexibility is to do regular stretching exercises. Stretch slowly, without bouncing, holding each stretch for 10-20 seconds.
  • Strength: Muscle strength can be improved by forcing the muscles to work against increasing amounts of resistance.
  • Nutrition: According to the American Heart Association, an ideal daily menu should consist of 50-60% carbohydrates (pasta, rice, grains, fruits and vegetables); 15% protein (meat, fowl, fish, dairy, peas, beans) and 30% or less of calories from fat (animal fat, whole dairy products, cooking oils).

Remember; never start an exercise or nutrition plan without first consulting with your healthcare provider to make sure that any changes are compatible with existing health or medical concerns.
