Consider running, for instance. A sprinter will focus on developing fast-twitch muscle fibres using plyometric exercises and strength training. The focus is on improving speed, strength and power. Marathoners, on the other hand, focus on developing cardiorespiratory fitness, muscular endurance and stamina. Sprinters also have perfect timing and immense power, and can switch on a burst of acceleration over a short distance. However, the sprinter’s attribute of pure power entailing plenty of fast-twitch muscle becomes a liability in the mountains. For mountain climbers, it is the power-to-weight ratio. They invariably have a bird-like frame, are mentally very tough and have immense stamina. Unfortunately, mountain climbers can’t sprint with the best.
