FITT (frequency, intensity, time and type) is a fitness principle that helps ensure an adequate quality and quantity of movement to reach the desired level of physical fitness. Frequency: For Amber to improve on her cardiovascular endurance levels, she must be training from 1 to 3 days out of the week for her body to adapt and adjust to her stress body systems. Adaption is the result of the body’s progression in physical fitness. Intensity: Intensity refers to the amount of effort an individual should be putting towards bettering your fitness levels. To measure the amount of intensity and effort being put into exercise, you’re target heart rate should be calculated. While exercising, the level of effort should be sustained to keep your heart rate within the target heart rate zone for a certain amount of time.
Time: Typically, while exercising the amount of time within the target heart rate zone should last for a minimum of 20-30 minutes and should slowly increase to 40 or higher. Exercising for 60 minutes or more can exhaust the body and can cause overtraining and possible injury. A minimum of 6 weeks can show results of physical fitness levels improving and adaption taking place on the body. Type: The ideal type of exercising is constant movement of the body while using large muscle groups. Swimming, running and cycling are some examples of sports that make good use of large muscle groups.
An individual’s cardiorespiratory system can improve and adapt while excising with large muscles groups because of the requirements from it.
