Abbreviations and definitions
| Name | Description | Used on site |
|---|---|---|
| [La+Pyr]B | The concentration in mmol/l of Lactate and Pyruvate in the bloodstream. | |
| [La+Pyr]M | The concentration in mmol/l of Lactate and Pyruvate in the muscle. | |
| [Lass] | Lactate concentration in Steady state (in mmol/l). | |
| Aerobic | In the context of the TREFF-model, aerobic refers to the process of generating energy in the presence of oxygen. It describes the part of the total energy demand in the muscle that is regenerated by the use of oxygen, which is measured by the amount of ATP usage | |
| Anaerobic | In the context of the TREFF-model, anaerobic refers to the process of generating energy without oxygen. It describes the part of the total energy demand in the muscle that is regenerated by the use of non-oxygen sources, which is measured by the amount of ATP usage | |
| ANS | ANS stands for Autonomic Nervous System. It is part of the peripheral nervous system and controls vital functions such as heartbeat, breathing, and digestion. It is also involved in the acute stress response, where it works with the endocrine system to prepare the body to fight-or-flight. | |
| Base Excess | Base excess (BE) is a measure of the amount of acid or base that would have to be added to the blood to restore the normal pH of 7.4 at a certain temperature and carbon dioxide pressure. It indicates the metabolic acid-base status of the body. A normal value is -2 to +2 mEq/L. A negative value means a base deficit, while a positive value means a base excess. | |
| Cardio Vascular response | Cardiovascular response refers to the physiological changes that occur in the cardiovascular system, which comprises the heart, blood vessels, and blood, in order to distribute oxygen and nutrients to the body's tissues and remove waste products. | |
| Fatty acids | Fatty acids are carboxylic acids with long hydrocarbon chains. The chains can be either saturated (no double bonds between carbon atoms) or unsaturated (one or more double bonds between carbon atoms). Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, ranging from 4 to 28. Fatty acids are important components of lipids, which are fat-soluble molecules found in living cells. They serve as a source of fuel for the body and play a role in many cellular processes. | |
| Glycogen | Glycogen is a large, branched polysaccharide that is the main storage form of glucose in animals and humans. It serves as an important energy reservoir; when energy is required by the body, glycogen is broken down to glucose, which then enters the glycolytic or pentose phosphate pathway or is released into the bloodstream. |

Subscription questions
At the moment, the TREFF site doesn't charge anything for its services. However, there is a monthly limit on the number of calls per account to prevent excessive data usage. If you need more data calls, please email me. If you appreciate our work and would like to support us, feel free to use the "Buy Me a Coffee" button.
