- Abstract
Supplements of either magnesium or creatine have been previously reported to improve ergogenic performance. This study compared ergogenic activity and recovery in rats by swimming them to exhaustion, resting them for 30 minutes, and then re-swimming them to exhaustion after previously receiving no creatine supplementation, creatine monohydrate (CM) alone, CM plus MgO, CM plus Mg amino acid chelate, or Mg creatine chelate supplements for 8 days. Daily doses of Mg and creatine were 5 mg and 100 mg, respectively, per kg body weight. The source of the Mg appeared to affect ergogenic performance. The Mg creatine chelate not only resulted in significantly (P < 0.01) greater swimming time to exhaustion, but it was the only Mg source that resulted in significant (P < 0.05) ergogenic recovery during the second swimming period. It was concluded that when Mg was chelated to CM in a 1:1 molar ratio, the resulting molecule allowed greater ergogenic activity than when the metabolites were supplied as admixtures with Mg coming from other sources.
