Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or break periods. The high-intensity periods are typically at or close to anaerobic exercise , while the recovery periods involve activity of lower intensity. [ 1 ]
Anaerobic exercise is a type of exercise that breaks down glucose in the body without using oxygen; anaerobic means "without oxygen". [1] This type of exercise leads to a buildup of lactic acid. [1] In practical terms, this means that anaerobic exercise is more intense, but shorter in duration than aerobic exercise. [2] Fox and Haskell formula
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.
For example, one 2016 study in PLOS ONE found that both sprint interval training (anaerobic) and high-intensity aerobic training led to improvements in lactate threshold and the onset of blood ...
Recovery Level 2 (Yo-Yo IR2). This is a tougher version of "Recovery Level 1". It "determines an individual's ability to recover from repeated exercise with a high contribution from the anaerobic system. [3] " Endurance Level 1 (Yo-Yo IE1). This may be used to test participants in less vigorous sports that usually last longer.
Physical fitness is achieved through exercise, among other factors.Photo shows Rich Froning Jr., four-time winner of "Fittest Man on Earth" title.. Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations, and daily activities.
Fartlek and interval training are similar, the main difference being the structure of the exercise. Fartlek is a Swedish word, meaning speed play. [2] This type of training is a combination of continuous (generally aerobic) and interval training (generally anaerobic), involving consistent changes of pace/intensity throughout the session. [2]
Fartlek is a middle and long-distance runner's training approach developed in the late 1930s by Swedish Olympian Gösta Holmér. [1] It has been described as a relatively unscientific blending of continuous training (e.g., long slow distance training), with its steady pace of moderate-high intensity aerobic intensity, [2] and interval training, with its “spacing of more intense exercise and ...
