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] Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time. [ 2 ]
To add challenge to the workout, each of these sprints may start at predetermined time intervals - e.g. 200 metre sprint, walk back, and sprint again, every 3 minutes. The time interval is intended to provide just enough recovery time. A runner will use this method of training mainly to add speed to their race and give them a finishing kick.
HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity, because the body significantly recruits anaerobic energy systems ...

The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
Exercise – any bodily activity that enhances or log physical fitness and overall health and wellness. It is performed for various reasons including strengthening muscles and the cardiovascular system , honing athletic skills, weight loss or maintenance, as well as for the purpose of enjoyment.
The physical activity level (PAL) is a way to express a person's daily physical activity as a number and is used to estimate their total energy expenditure. [1] In combination with the basal metabolic rate , it can be used to compute the amount of food energy a person needs to consume to maintain a particular lifestyle.
The 2018 report linked the lack of physical activity to about $117 billion in annual healthcare costs and about 10% of premature mortality. While the 2008 edition gave recommendations for children from age 6 years onward, the 2018 edition includes guidelines for children aged 3 years and older. [2]
