Creatine supplementation in the elderly: Is resistance training really needed?

Introduction:
Decreases in muscle mass, strength and power are associated with ageing, all of which increase the risk of falls, and cause a loss of independence. Creatine supplementation is often used in younger athletes to improve anaerobic performance, power and strength, however the potential benefits of creatine supplementation in older individuals are less clear.
Aim:
This review assesses the current literature on whether creatine supplementation in the presence of resistance training enhances physical performance in older adults above and beyond those undertaking resistance training alone or only taking creatine supplements.Results:
Whilst reports are conflicting, there is good evidence to suggest that creatine supplementation with resistance training increases muscular endurance, lower body strength and lean body mass; this is above results obtained with creatine supplementation or resistance training alone. The increased muscle mass observed with training has previously been shown to lead to increased bone mineral content and an associated reduced fracture risk; however, the additional benefits of creatine supplementation on this are less clear, and more work is needed to confirm whether exogenously taken creatine will benefit bone mineral density.
Conclusion:,br>Creatine supplementation in the elderly may lead to increased muscle mass, endurance and performance, and those who undertake resistance training may show further improvements with creatine supplementation. However, for elderly subjects who do not partake in resistance training, creatine supplementation offers significant improvements in increasing muscular mass and strength, and increasing their quality of life, whilst these benefits are lower on the whole than those who undertake regular resistance training.
