Cardiorespiratory Fitness

Primary functions of the cardiorespiratory system

-Deliver nutrients to and remove metabolic waste products from the tissue. -Assists with maintenance of normal function at rest and during exercise. (Temperature, Fluid balance, Hormones, pH balance)

Role of VO2max

-Most valid measure of cardiorespiratory fitness. -VO2max= maximal aerobic capacity (max oxygen use during exercise) -VO2max measures the endurance of the cardiorespiratory system/skeletal system during exercise.

Why is cardiorespiratory fitness important?

-Oxygen is required to fuel muscles during submaximal activities. (Aerobic activity)

Cardiorespiratory Fitness

-The ability of the circulatory and respiratory systems to supply oxygen-rich blood to skeletal muscles during sustained physical activity. -Ability to perform large-muscle, dynamic, moderate-to-high intensity exercise for prolonged periods.

Vascular

Carries blood

Reflects the functional capabilities of?

Heart, blood vessels, lungs, skeletal muscles.

Cardiorespiratory Fitness is also known as?

Maximal aerobic capacity, aerobic power, functional capacity, physical work capacity(PWC), Cardiovascular/cardiopulmonary endurance, fitness, or capacity.

Heart

Pumps blood

Poor cardiorespiratory health leads to?

Short term loss of endurance and long term heart disease or risk of heart failure.

Lungs

Site of respiration

Left Ventricle

pumps oxygenated blood to the body
