Problem 40

Athletes burn fat at a maximum rate when they exercise at an intensity near the lactate threshold-the
point at which lactic acid starts to build up in the muscles. In addition, athletes who consume the greatest amounts of oxygen during intense exercise $\left[\mathrm{VO}_{2 \mathrm{peak}}\right]$ burn the most fat. Researchers compared the lactate threshold and oxygen consumption of overweight subjects who did not exercise to those of highlytrained athletes.
