Abstract

This study aims to evaluate the effects of short-term sodium phosphate intake upon body composition, haemogram, maximal ergospirometer parameters and submaximal ones in the maximal fat oxidation zone (Fatmax). 20 active subjects participated in this study randomly divided into two groups: The experimental group which ingested sodium phosphate for 7 days (50 mg/kg lean mass) and the placebo group. Both performed an incremental maximal cycle ergo meter test following the Fatmax protocol, body composition assessment and blood analysis (CBC) before and after the supplementation period. In the experimental group, phosphate supplementation produced a decrease in weight and body mass index (BMI), an increase in maximal power output and it also improved energy efficiency in the Fatmax zone. No changes were observed in the parameters listed in the CBC. These results may attribute an ergogenic effect of sodium phosphate in aerobic activities and sports where body weight is considered to be an important factor for performance.
