Theoretical models of lactate accumulation

Theoretical models of lactate accumulation explain how and why lactate builds up in muscles during intense activity. These models suggest that when muscles work hard, they produce energy quickly, leading to increased production of lactate as a byproduct. If the rate of lactate production outpaces the body's ability to clear it, levels rise, causing fatigue. Factors like muscle oxygen levels, enzyme activity, and blood flow influence this process. Overall, the models help understand the balance between energy demand and lactate removal, providing insight into muscle performance and endurance limits.
