Abstract
The patient adopted a road work, as a method of training to start again after some weeks pause.As a result, he was suffered from pain on lateral aspect of the knee (iliotibial band friction syndrome) on the first day of training. After taking rest for a few week, he started training with a bicycle in order to make up for a dificit in exercise, which resulted in development of quadriceps femoris muscle and decreased knee pain. This method of training provided enough energy expenditure as a measure of prevention of obesity for a general person. This method of training also prevented from other injuries. Therefore, it seemed to be valid to build up the basic muscle endurance and power of the legs and a useful method before activity starting training in various ways. Though muscular durability was raised, a muscle power was not raised enough by the bicycle training only. It was thought that in order to make athletic performance at higher levels, other power training was additionaly needed.
