Abstract
The effects of oral vanadyl sulfate (VOSO4) (0.5 mg/kg/day) on anthrop ometry, body composition, and performance were investigated in a 12-we ek, double-blind, placebo-controlled trial involving weight-training v olunteers. Performance was assessed in the treatment (VS) and placebo (P) groups using 1 and 10 repetitions maximum (RM) for the bench press and leg extension. Thirty-one subjects completed the trial, with 2 VS subjects withdrawing because of apparent side effects. There were no significant treatment effects for anthropometric parameters and body c omposition during the trial. Both groups had significant improvements in performance but the only significant effect of treatment was a Trea tment x Time interaction in the 1 RM leg extension (p = .002), which c ould have arisen because the VS group had a lower performance at basel ine in this test. It was concluded that oral vanadyl sulfate was ineff ective in changing body composition in weight-training athletes, and a ny modest performance-enhancing effect requires further investigation.
