Abstract: Objectives. – We developed a non-invasive method allowing for an accurate analysis of the locomotion pattern in mouse. Synthesis of facts. – This method is based on cineradiography which associates high speed cinematography (250 pictures/s) and X-ray photography. It has been applied to the study of swimming exercise in a constant flow swimming pool. Our results provide the first evidence that swimming is characterized by micro intermittence which is defined as cyclic sequence of a power stroke time which is followed by a latency time. The duration of these two steps is within the range of m second. The functional relevance of each segment and the change of its time duration during training constitute a key of performance improvement. [Copyright &y& Elsevier]
