Heart rate, aerobic/anaerobic metabolism and lactate threshold are familiar terms for both professional and amateur athletes.
Blood lactate concentration reliably indicates how the body is responding to endurance exercise.
The right training can improve performance, but nutrition also plays a role by helping to sustain speed and stamina.
Carbohydrate- and electrolyte-based drinks are well established for delivering fast energy when fatigue sets in.
However, GELITA investigated whether continuous preparatory supplementation with specific Bioactive Collagen Peptides (BCPs) could also improve endurance performance.
Three studies using PeptENDURE, developed for endurance athletes, produced significant results.
Understanding the importance of lactate
Blood lactate levels are critical for endurance athletes; they reveal which energy pathways the body is drawing on during exercise.
Lactate is a by-product of fast, oxygen-independent energy production from carbohydrates — a pathway the body relies on during intense physical effort.
When lactate levels rise sharply, muscle metabolism becomes acidic and fatigue follows.
