This study examined the relationship between stroke motion and subjective output intensity for velocity during 50 m crawl stroke swimming. Thirty nine female subjects, including from elementary school to varsity swimming competitors, performed 20, 40, 60, 80 and 100 % for relative perceived exertion of swimming velocity. Kinematics and temporal characteristics of selected stroke phases were identified to describe key elements of output intensity for velocity. Results were obtained as follows; The subjective output intensity modified for water resistance was significantly correlated with objective intensity at given conditions (r = 0.986 p<O.O1 Y = 0.87X + 9.08). Increasing and decreasing for swimming velocity during 50 m crawl stroke, it depends upon SR remarkably even with maximum and sub-maximum effort. Two stroking patterns revealed in ascending the swimming velocity, SR showed higher values according with less SL or nothing change. Therefore, the changes of SL could be determined by the percentage of glide phase time, stroke velocity, and sculling technique during underwater stroking.
