Abbreviations and definitions

Name	Description	Used on site
[Ca]²⁺	The [Ca]²⁺ concentration in mmol/l. [Ca]²⁺ refers to calcium ions. Calcium ions (Ca²⁺) contribute to the physiology and biochemistry of organisms' cells. They play an important role in signal transduction pathways, where they act as a second messenger, in neurotransmitter release from neurons, in contraction of all muscle cell types, and in fertilization.

Fatigue-Curve	This calculation is based on the relation of the neural imput to the muscle-cells from 0% to 100%. This creates an increase in [Ca]²⁺ making the muscle contract. Due to the state of the 3 types of fatigue, a different amount of power in (VO_2tot) can be produced. No Fatigue: stands for the VO_2tot when there is no warming up Fatigue 1: stands for the VO_2tot if we look at the metabolic state in the muscle. Fatigue 1 and 2: Also takes in account the amount of KHD in the muscle making the VO_2tot drop. Fatigue 1, 2 and 3: Also takes in account the cardiovascular effects that drop the VO_2tot.

VO_2tot	VO_2tot represents the total amount of oxygen (VO₂) required to resynthesize all the ATP that is utilized at a given intensity. However, in reality, there is always some glycolysis (vLa) and sometimes also a change in [GP] that results in the actual VO₂ having a different value.
