Anaerobic Glycolysis

A metabolic process that breaks down glucose into pyruvate without the use of oxygen, producing a small amount of energy (ATP) relatively fast with lactate as a byproduct. It is commonly used during short, high-intensitive activities (up to about 2 min time duration).

Anaerobic Threshold

The anaerobic threshold is the exercise intensity at which the body begins to accumulate lactic acid in the bloodstream faster than it can be removed. This point marks the transition from primarily aerobic energy production (using oxygen) to anaerobic energy production (without oxygen). It is an important indicator of cardiovascular fitness and endurance, often used by athletes to optimize training intensity and performance.

Training Intensity

A measure of how hard the body is working during physical activity, often expressed as a percentage of maximum effort, heart rate, or weight lifted relative to one’s maximum capacity.

Training Volume

The total amount of work performed in a training session or over a period of time, typically measured as the product of sets, repetitions, and weight lifted in resistance training, or total duration/distance in endurance training.

V̇LaMax

Abbrevation for the maximum lactate production rate. An estimation of the maximum rate at which an athlete’s body can produce lactate during anaerobic metabolism. It reflects the capacity of the glycolytic system and plays a role in determining endurance and sprint performance. Higher V̇LaMax values are associated with greater anaerobic power, while lower values are beneficial for endurance efficiency.
