The effects of transcutaneous electrical stimulation and submaximal swimming on blood lactate removal following a maximal effort 200 yard frontcrawl
The purpose of this study was to evaluate the effect of recovery modes on lactate removal in swimmers. Thirty competitive swimmers (males, n = 17; females, n = 13) volunteered for the study. After warming up, participants sprinted a 200-yd frontcrawl and performed a 20-min randomized-counterbalanced recovery: rest, H-wave®, and submaximal swim. A multifactorial repeated measures 2 x 3 x 3 (sex, recovery mode, and time) ANOVA was conducted; a Scheffé's Confidence Interval was conducted for a significant interaction. Four simple effects were present: swim was significantly less than rest (p = .0019) at mid-recovery; H-wave® was significantly less than rest (p = .0063) at post-recovery; swim was significantly less than rest ( p < .0001) at post-recovery; and swim was significantly less than H-wave® (p < .0001) at post-recovery. H-wave® and submaximal swimming appear to be effective in reducing lactate; however, swimming reduced lactate to the greatest extent.
