CREATINE IMPROVES BODY MASS AND DYNAMIC STRENGTH PERFORMANCE
Kreider, R. B., Ferreira, M., Wilson, M., Grindstaff, P., Plisk, S., Reinardy, J., Cantler, E., & Almada, A. L. (1998). Effects of creatine supplementation on body composition, strength, and sprint performance. Medicine and Science in Sports and Exercise, 30, 73-82.
This investigation assessed the effects of 28 days of creatine supplementation during training on body composition, strength, sprint performance, and hematological profiles. NCAA football players (N = 25) were matched-paired and assigned to supplement their diet for 28 days during resistance/agility training with Phosphagen HP (a glucose/taurine/electrolyte supplement) placebo, or Phosphagen HP and creatine monohydrate. Measurements were taken before and after the treatments.
Hematological parameters remained stable across all groups. Total body weight increased significantly in the creatine group while no differences were observed in the percentage of total body water. The creatine group also improved in total scanned body mass, fat/bone-free mass, bench press lifting volume, overall resistance training activity volume, and the total work performed during the first five 6-s sprints.
Implication. The addition of creatine to a glucose-electrolyte supplement increased body mass and performance measures in football players.
