Vedclass · Answer

(B) During an all-out sprint,the body relies primarily on anaerobic respiration because the demand for $ATP$ exceeds the rate at which aerobic respiration can supply it. This leads to the rapid breakdown of glucose into lactic acid via the anaerobic pathway. The accumulation of lactic acid in the muscle fibers causes a decrease in $pH$,which interferes with muscle contraction and leads to muscle fatigue. Consequently,the body cannot sustain such high-intensity activity for more than approximately $40$ seconds.

An all-out sprint cannot continue for more than $40$ seconds because:
