Document Summary
Three different exercise intensities, flat green line is steady state. And under the green line is the energy state filling the blue box with energy supply by the aerobic system. The area at the triangle that is not covered by the green line is anaerobic energy supply meaning our two energy systems. Resting lactic acid as we said is 1 milimoler and it is that ditched line here represents the concentration of blood over time. And if you"re exercising for mild intensity for 10 minutes and followed by recovery what you"re seeing here is a tiny blip in the blood that ruse the blood lactic acid above 1 milimoler. Under moderate conditions we have a bigger blip in blood lactic acid because the area occupied by the aerobic system is larger, glycolysis contribution is larger and we see an increase maybe up to 4-5 milimoler here.
