We report an in vivo and ex vivo characterization of cardiorespiratory fitness and muscle oxidative capacity in a 91-yr-old female who holds the W90 + 200-m world record. She exhibited a high muscle oxidative capacity and a muscle fiber profile with large, well-vascularized slow fibers and a relatively high proportion of fast fibers. These findings suggest that components of the oxygen transport and utilization system can be well-preserved into very advanced age in a lifelong sprinter.
