![]() ![]() Henry Taylor at the University of Minnesota and Swedish scientists Per-Olof Åstrand and Bengt Saltin made notable contributions in the 1950s and 60s. Building on this work, scientists began measuring oxygen consumption during exercise. German physician Otto Meyerhof and Hill shared the 1922 Nobel Prize in Physiology or Medicine for their independent work related to muscle energy metabolism.

Įxamples of cardiovascular or aerobic exercise are medium- to long-distance running or jogging, swimming, cycling, stair climbing and walking. Aerobic exercise causes a remodeling of mitochondrial cells within the tissues of the liver and heart. Mitochondria are organelles that rely on oxygen for the metabolism of carbs, proteins, and fats. Aerobic exercise may be better referred to as "solely aerobic", as it is designed to be low-intensity enough that all carbohydrates are aerobically turned into energy via mitochondrial ATP production. Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time. "Aerobic" is defined as "relating to, involving, or requiring oxygen", and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. ![]() Cardio and muscle endurance exercise session using plastic steps or platformsĪerobic exercise (also known as endurance activities, cardio or cardio-respiratory exercise) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process.
