Effects of dietary fat on muscle substrates, metabolism, and performance in athletes

Article Abstract:

Results demonstrate that following a five-week high-fat diet, intramyocellular lipid increases more than two-fold, whereas no change occurs with muscle glocogen reserves. Data indicate that lipids contribut to a greater extent to the total energy turnover therby maintaining endurance performance capacity at moderate to high-exercise intensities.

Creatine supplementation-part 1: performance, clinical chemistry, and muscle volume

Article Abstract:

Research indicates that creatine (Cr) supplementation can improve short-term athletic performance without detrimental side effects. Results are based on a study of 10 well-trained males to determine the effects of Cr supplements on muscle work, Cr metabolism in the blood and urine, and muscle volume in lower limbs.

Creatine supplementation-part 2: in vivo magnetic resonance spectroscopy

Article Abstract:

Research indicates increased creatine (Cr) levels and a larger phosphocreatine/adenosine triphosphate ratio in skeletal muscles when creatine supplementation is given. Results are based on a study of 10 males using non-invasive magnetic resonance spectroscopy.
