Research Abstract

The aims of this study were to calculate the muscular mechanical efficiency and to clarify an affect factor during running. Muscular mechanical efficiency was determined as internal and external work for energy consumption from experiments for citizen runners. Running and cycling economy (oxygen consumption for the constant velocity), jump performance and elastic ability were measured. The further problem is to estimate the influence of the elastic ability in the change of the muscular mechanical efficiency.
