Abstract:
After surgery, it is very important for a runner to maintain foot and leg flexibility and muscle strength. Isometric exercises, the type of muscular contractions that occur when the ends of the muscles are fixed (so activity is evidenced by increase in tension without change in length), are very useful as they develop power and strength and help in regaining power and strength lost by injuried muscles. Isometrics are of greater value when performed in several daily sessions instead of once a day.
