Final answer:
Cardiovascular fitness refers to the efficiency of the heart, blood vessels, and lungs in delivering oxygen during physical activity. F.I.T.T. stands for Frequency, Intensity, Time, and Type, which are important factors in designing an exercise program. Aerobic exercise requires continuous movement and improves cardiovascular fitness, while anaerobic exercise involves short bursts of intense activity for strength and power.
Step-by-step explanation:
Cardiovascular Fitness:
Cardiovascular fitness refers to the ability of the heart, blood vessels, and lungs to efficiently supply oxygen and nutrients to the muscles during physical activity. It is important because it improves overall health, reduces the risk of chronic diseases, increases endurance and stamina, and enhances the body's ability to recover from exercise.
F.I.T.T.:
F.I.T.T. stands for Frequency, Intensity, Time, and Type. It is a principle used to design and structure an exercise program. Frequency refers to how often you exercise, intensity is the level of difficulty or effort, time refers to the duration of each exercise session, and type represents the specific activities or exercises performed.
Aerobic vs. Anaerobic Exercise:
Aerobic exercise involves activities that require continuous movement of large muscle groups, such as jogging, swimming, or cycling. It improves cardiovascular fitness by increasing the demand for oxygen and improving lung capacity. Anaerobic exercise involves short bursts of intense activity, such as weightlifting or sprinting. It focuses on building strength and power by working the muscles without relying on oxygen.
