The aims of this study, written by Jason D. Vescovi, Olesya Falenchuk, and Greg D. Wells and published in 2011 by International Journal of Sports Physiology and Performance were to describe the postrace blood lactate concentration [BLa] of elite-standard Canadian swimmers in the finals of the short-course National Championships, and to determine whether there is a relationship between active recovery distance and blood lactate removal.

Vescovi et al. examined postrace [BLa] after the final races in 100 male and female swimmers competing in the 2009 Canadian National Swimming Championships, as well as the effect of active recovery distance on blood lactate concentration removal. They also developed a model that could be used by coaches as a practical tool during competitions where multiple races are performed on a single day.

Lactate measurements were taken within 3 to 5 min after race completion using a Lactate Pro analyser, which has actually been discontinued and replaced by the newer and improved version Lactate Pro 2.

After performing this study, the authors found that swimmers competing at an elite standard display similar postrace [BLa], and that age was not a significant determinant of [BLa] in adolescent and young adult high performance swimmers.
