The Effect and Safety of Short-Term Creatine Supplementation on Performance of Push-Ups

The effects of short-term oral creatine (Cr) supplementation on exercise performance and on blood pressure and renal function were assessed. Thirty-five healthy, active duty, U.S. Army volunteers (20 men and 15 women; age 22-36 years) at Fort Sam Houston, Texas, supplemented their diet for 7 days wi...

Zusammenfassung:	The effects of short-term oral creatine (Cr) supplementation on exercise performance and on blood pressure and renal function were assessed. Thirty-five healthy, active duty, U.S. Army volunteers (20 men and 15 women; age 22-36 years) at Fort Sam Houston, Texas, supplemented their diet for 7 days with 20 g/day of either Cr or taurine (as placebo). There was no significant difference in 2-minute push-up counts between the Cr and taurine groups from before to after supplementation (p = 0.437; power = 0.98). The Cr group demonstrated a significant increase in serum creatinine levels (p less than 0.001), compared with the taurine group, and this increase could be misinterpreted as impairment of renal function.
