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.
