Medical Sciences

How does the motor unit recruitment pattern described in explainthe increase in blood lactate which occurs above 50-60% Vo2max?Blood lactate is the buffered form of lactic acid derived fromcellular anaerobic glycolysis. (HINT: connect motor unitrecruitment order with collective metabolism. And high/lowintensity training

My answer so far: The motor unit recruitment pattern describedin the lecture materials tells us that when there is low intensityactivity (rest to about 50% of Vo2max), minute ventilation (VE)parallels Vo2. We also learn that onset blood lactate accumulation(OBLA) occurs at about 66% Vo2max, and occurs between 50% and 80%Vo2max.
