The BOD holds legal responsibility for the organisation and for oversight from the improvement with the strategic course.
On the other hand, anaerobic metabolism briefly provides lactic acid on the muscle building an oxygen credit card debt whereby the muscle mass fatigues and needs a Restoration time period to eliminate the lactic acid.
