Vasoconstriction
The procees whereby blood vessels narrow their diameter as a response to a decreased demand for oxygen delivery to muscle tissue
Vasodilation
The process whereby blood vessels increase their diameter as a response to an increased demand for oxygen delivery to muscle tissue
Lactate Inflection Point (LIP)

Maximum Heart Rate

Vo2 Max
the maximum amount of oxygen that an individual can utilize during intense or maximal exercise.
