Does lactic acid have a role in the B Strong BFR training system?
Yes. Lactic acid is one of many factors that helps stimulate adaptation and growth of muscle. However, it is not a goal, in and of itself, to get high lactate levels in blood with the B Strong Training System. Lactate levels accumulate in muscle fibers when the rate of glycolysis (breakdown of carbohydrates, glycogen and glucose) exceeds the rate of the mitochondria to take in and process carbohydrates with oxygen. By limiting the circulation with the B Strong Training System, we reduce the ability of the circulation to re-supply oxygen to the working tissue. This results in the earlier onset of high lactate concentrations in a muscle fiber from a workout at much lower absolute work loads.
If there are no micro tears in the muscles with the B Strong, what does the increase in lactic acid and subsequent secretion of growth hormones do?
Micro tears or muscle fiber damage are not necessary to stimulate lactate production or Growth Hormone secretion. It is the disturbance of homeostasis that raises lactate concentrations and stimulates secretion of Growth Hormone and they, in turn, stimulate an anabolic response in exercising tissues.
