Why is it difficult to find a runner who competes equally well in both 100-m and 10,000-m races? The primary reason is that our muscles contain two main types of muscle fibers, called slow and fast muscle fibers. Slow muscle fibers are muscle cells that can sustain repeated contractions but don¡¯t generate a lot of quick power for the body. They perform better in endurance exercises, like long-distance running, which require slow, steady muscle activity. Fast muscle fibers are cells that can contract more quickly and powerfully than slow muscle fibers but fatigue much more easily; they function best for short bursts of intense activity, like weight lifting or sprinting.
 
¨ç reasons for runners to develop strong muscles
¨è differences between slow and fast muscle fibers
¨é comparison of sprinting with long-distance running
¨ê necessity of building muscles for long-distance runners
¨ë relationship between muscle fibers and physical fatigue
