Stroke parameters analysis of different levels swimmers

Abstract

The aim of this paper is to present a comparison Of the stroke parameters Of different abilities swimmers by inertial sensory data.
There are nine male college students to participate in the research, and according to the swimming performance divided into elite, well- trained and recreational. We fixed the inertial sensor on the hands and back of the participants to capture the sensory data in the swimmers. Results: A) There are no significant differences in the stroke frequency between different levels Ku-Chen Huangl ,Meng-ShiuanPan2 of swimmers. B) Elite swimmers have a higher per stroke length than the other groups. C) Elite swimmers have higher average speed than other groups. D) Three groups of swimmers have significant differences in body rotation, pitch and yaw, recreational group have greater body rotation angle than elite group and well-trained group.
