The Effect of Sodium Bicarbonate Ingestion on Blood Lactate Levels and Interval Performance of Elite Females Swimmers
Message:
Abstract:
The purpose of this study was to examine the effect of sodium bicarbonate ingestion on blood lactate levels and interval performance of elite swimmers. Ten elite female swimmers in Foolad Mobarakeh Sepahan club in Isfahan (age: 15.3 ± 1.7 yr, height: 155.4 ± cm, weight: 51.3 ± 3.16 kg, %Fat: 20.3 ± 1.7 and BMI: 21.3±5.4 kg/m2), presented two different days (separated for a minimum of 3 days and maximum of 7 days) in order to perform the tests. They ingested 0.3 g. kg-1 of body weight of NaHCO3 or placebo in each of the experimental procedures. The substances were ingested in seven doses over a 90-min ingestion period. The first dose was administered two hours before the first time trial. The subjects swam 100 m breast Crowley and then participated in passive recovery for 15 minutes and then 100 breast Crowley test was repeated. Blood lactate, was measured from subject's finger tip in 5 steps: before taking placebo or sodium bicarbonate, 3, 6, 15 minutes after the first swim and 3 minutes after the second swim. Analysis of variance (ANOVA) with repeated measures revealed significant decreases in blood lactate levels at 3, 6 and 15th min of recovery in bicarbonate group compared to placebo. Although it was observed an improvement in performance in supplement group but it was not significant versus placebo (p=0.09). The results suggest that sodium bicarbonate ingestion prior to sprint swim performance consisting of short rest intervals between events is an ergogenic procedure for decreasing lactate and improving performance.
