Question

Please explain.

2. If your exercise rate exceeds your body's ability to supply oxygen to your muscles, you are A) rapidly depleting your creatine phosphate reserves B) exercising anacrobically C) rapidly depleting your glycogen reserves. D) exercising below your oxygen capacity

Answer 1

ANSWER

2. B.Exercising anaerobically.

            * If the person exercise more than oxygen supplying ability

              of the body then it become considered as a anaerobic respiration.

            * In this energy requirement of muscle meet by energy stored in the

               muscles of the body through glycolysis.

            * In glycolysis process glycogen in the muscle converted to form glucose.

            * Glycolysis process occur in the muscle cells at the time of anaerobic exercises

               not use oxygen due to the need of rapid production of energy.

            * This process cause production of lactic acid as a by product and it result in muscle

               fatigue.
