The high-intensity exercise should be done at near maximum intensity. The medium exercise should be about 50% intensity. The number of repetitions and length of each depends on the exercise, but may be as little as three repetitions with just 20 seconds of intense exercise. [12] The specific exercises performed during the high-intensity ...
Some exercisers find interval training less monotonous than continuous-intensity exercise. [4] A number of studies confirm that in young and healthy individuals, sprint interval training appears to be as effective as continuous endurance training of moderate intensity, and has the benefit of requiring a reduced time commitment.

The Yo-Yo intermittent test is aimed at estimating performance in stop-and-go sports like football (soccer), cricket, basketball and the like. It was conceived around the early 1990s by Jens Bangsbo , [ 1 ] a Danish soccer physiologist, then described in a 2008 paper, "The Yo-Yo Intermittent Recovery Test". [ 2 ]

Continuous training typically involves aerobic activities such as running, cycling, swimming, and rowing. Continuous training can be performed at low, moderate, or high exercise intensities , [ 1 ] and is often contrasted with interval training , often called high-intensity interval training.
An informal method to determine optimal exercise intensity is the talk test. It states that exercise intensity is “just about right”, when the subject can “just respond to conversation.” [5] The talk test results in similar exercise intensity as the ventilatory threshold and is suitable for exercise prescription. [6]
The talk test is a sub-maximal, incremental exercise test which allows individuals to recognise their exercise training intensity. [9] The self-administered test allows individuals the ability to determine if they are exercising at the appropriate heart rate and intensity level based on their ability to speak comfortably whilst exercising.
Skeletal muscle burns 90 mg (0.5 mmol) of glucose each minute during continuous activity (such as when repetitively extending the human knee), [11] generating ≈24 W of mechanical energy, and since muscle energy conversion is only 22–26% efficient, [12] ≈76 W of heat energy.
