    Cardiovascular fitness - is the ability of the heart (cardio) and circulatory system (vascular) to supply oxygen to muscles for an extended period of time. Cardiovascular is also called cardiorespiratory (lungs) fitness. Usually the mile run or some other type of continuous fitness activity (12 minute run, cycling, step-test, etc.) is used to assess cardiovascular fitness. 

     

    Muscular strength and endurance is the muscle’s ability to produce effort or perform work. 

    • Muscular endurance refers to the ability of the muscle to work over an extended period of time without fatigue. Performing pushups and sit-ups or crunches for one minute is commonly used in fitness testing of muscular endurance.
    • Muscular strength refers to the maximum amount of force a muscle can exert against an opposing force. Fitness testing usually consists of a one-time maximum lift using weights (bench press, leg press, etc.).

     

    Flexibility - is the ability to move a body part through a full range of motion at a joint (ROM). The sit-and-reach is commonly used to determine flexibility.
