Isn't high intensity self-defined? Meaning someone out of shape's high intensity will be less intense than someone who is in shape?
- jacques_chester 13y agoIn sports science, "intensity" refers to a percentage of some maximal performance. In weight / strength training, "intensity" refers to percentage of a 1-rep maximum. So if you squat 100kg, a 70kg squat is 70% intensity. Meanwhile, in various aerobic trials, "intensity" could be defined as percentage of measured VO2 max. This is important because one of the most influential studies on high intensity interval training (Tabata) was calibrated this way. Cyclists were tested to their sprint VO2 max and then made to push past that level for 20 seconds, then 10 seconds of rest; repeated 8 times.
