Effects of calcium pyruvate supplementation during training on body composition, exercise capacity, and metabolic responses to exercise.

Objective: We evaluated the effects of calcium pyruvate supplementation during training on body composition and metabolic responses to exercise.

Methods: Twenty-three untrained females were matched and assigned to ingest in a double blind and randomized manner either 5 g of calcium pyruvate (PYR) or a placebo (PL) twice daily for 30 d while participating in a supervised exercise program. Prior to and following supplementation, subjects had body composition determined via hydrodensiometry; performed a maximal cardiopulmonary exercise test; and performed a 45-min walk test at 70% of pre-training VO2 max in which fasting pre- and post exercise blood samples determined.
