This study aimed to examine the relationship between the maximal lactate accumulation rate (ċLa) and sprint performance parameters in male competitive swimmers. Seventeen male competitive swimmers volunteered to perform a 20 m maximal front crawl sprint without pushing off the wall from a floating position. ċLa was determined by the 20-m sprint time and blood lactate measured before and after the 20 m sprint. For the sprint performance parameter, a 50 m time trial with the front crawl swimming stroke was conducted, and the times taken from 0 to 15 m, 15-25 m, 25-35 m, and 35-45 m were analyzed. A semi-tethered swimming test was conducted to investigate the load-velocity profile of each swimmer. From the load-velocity profile, theoretical maximal velocity (V), maximal load (L) and relative maximal load (rL) were examined. The slope of the load-velocity profile was also determined. According to the results, ċLa correlated with 50 m front crawl performance ( = -.546, < .05). Moreover, a higher ċLa was related to faster 0-35 m section time. Furthermore, ċLa correlated with L ( = .837, < .01), rL ( = .820, < .01), and load-velocity slope ( = .804, < .01). ċLa is a good indicator of 50 m front crawl performance in male swimmers, and higher glycolytic power contributes to the faster time at the beginning of the sprint race. ċLa could also evaluate the ability of a swimmer to apply force to the water during high-intensity swimming.
