Up to a point‚ the available oxygen is sufficient to meet the energy needs of the body. However‚ when muscular exertion is very great‚ oxygen cannot be supplied to muscle fibres fast enough‚ and the aerobic breakdown of pyruvic acid cannot produce all the ATP required for further muscle contraction.
