Abstract
Swimming, as a sport beneficial to body and mind, also has a place in
international sports. For swimmers and coaches, it is always the most important to
improve the propulsion and reduce the resistance during swimming. This paper
briefly introduced the resistance of human body in swimming, described the
dynamic resistance of human body in arm stroke, and then introduced the principle of micro disturbance method which was used for measuring the dynamic resistance in swimming. Finally, ten swimmers from school team and ten beginners
were tested for the dynamic resistance in freestyle, backstroke and breaststroke
when they swam with arm stroke only. After adding micro resistance, the swimming speed of the subjects decreased when they swam with all their strength; the
speed of freestyle swimming was the largest, followed by backstroke and breaststroke before and after loading, and the swimming speed of school team members
was larger than that of beginners; the dynamic resistance and dynamic resistance
coefficient of breaststroke were the largest, backstroke was the second, freestyle
was the smallest, and the dynamic resistance and dynamic resistance coefficient
of school team members were always smaller than those of beginners no matter
the swimmer took which swimming style.
