Question

After resting for 10 minutes, you decide to perform another explosive, one-time movement such as a standing vertical jump and again, exert maximal effort. You briskly push yourself up from a chair and walk about 1.5 minutes to arrive at a wall where a vertical jump measurement can be made.

A) aerobic metabolism

B) lactic acid metabolism

C) anaerobic metabolism

Answer 1

C) Anaerobic metabolism

Generally exerting maximal effort or doing vigorous physical activities leads to drain in the energy.Our body undergoes different metabolism inorder to provide energy.Usually energy is produced via two ways aerobic and anaerobic metabolism.In normal condition aerobic metabolism is involved in providing adequate energy whereas the anaerobic metabolism occurs when the oxygen transport and oxygenation in the tissues are compromised,this conditions occur during explosive physical activities..Anaerobic metabolism leads to conversion of stored glucose into lactate in the muscle which acts as a energy fuel.Lactate is the intermediate by product of anaerobic metabolism hence it is not considered as a separate metabolism.

Hope this helps you:)
