This study investigated the separate and combined effect of short term creatine and sodium phosphate supplementation on body composition, performance, and blood chemistry. Ten subjects (5 male, 5 female) participated in each of four trials using a double blind, repeated measures design. Subjects were randomly assigned to ingest either 1000 mg of tribasic sodium phosphate (P), 5000 mg of creatine monohydrate (Cr), 5000 mg creatine and 1000 mg phosphate (C/P), or a glucose placebo (G) four times daily for five days. Venous blood samples, body composition, and metabolic testing were performed pre- and post-supplementation for all trials. Results indicate that following the phosphate trials, VO2max (8%) and the ventilatory anaerobic threshold were significantly elevated (10%). In contrast, both creatine loading trials resulted in a significant increase in body mass (1.35+/-0.22 kg, mean+/-SE) with no change in fat free mass (p<0.05). The only significant difference observed between concurrent creatine and phosphate loading and all other trials was an elevated power output (18+/-2.3 watts) suggesting that there may be some performance benefit to short-term creatine and phosphate loading.
