Cardiorespiratory fitness (CRF) refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. Scientists and researchers use CRF to assess the functional capacity of the respiratory and cardiovascular systems. These functions include ventilation, perfusion, gas exchange ...
Cardiovascular fitness is a measure of how well the heart, lungs, and blood vessels can transport oxygen to the muscles during exercise. It is an important component of overall fitness and has been linked to numerous health benefits, including a reduced risk of cardiovascular disease, improved cognitive function, and increased longevity.
Aerobic exercise, also known as cardio, is physical exercise [1] of low to high intensity that depends primarily on the aerobic energy -generating process. [2] ". Aerobic" is defined as "relating to, involving, or requiring oxygen", [3] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [4]
Benefits include improved thinking or cognition for children ages 6-13, short-term reduction of anxiety for adults, and enhanced functional capacity in older adults. [8] Regular physical activity can keep thinking, learning, and judgment skills sharp with age. It can also reduce the risk of depression and anxiety and improve sleep.
Aerobic conditioning is the use of continuous, rhythmic movement of large muscle groups to strengthen the heart and lungs (cardiovascular system), [1] as well as changes to the skeletal muscles. [2] Improvement in aerobic conditioning occurs when athletes expose themselves to an increase in oxygen uptake and metabolism, but to keep this level ...
“Understanding that one can have an equal improvement of cardiovascular outcomes with 1–2 days of exercise per week versus daily exercise spread over the course of the week, will provide ...
High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. [ 1 ] HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts.
Exercise intensity refers to how much energy is expended when exercising. Perceived intensity varies with each person. It has been found that intensity has an effect on what fuel the body uses and what kind of adaptations the body makes after exercise. Intensity is the amount of physical power (expressed as a percentage of the maximal oxygen ...
