The effect of NatraGuard(trademark), a novel cow's milk protein isolate, on muscle strength and body composition of postmenopausal women undertaking an exercise program.

One of the most visible signs of ageing is the loss of muscle mass. This loss of muscle mass has subtle, yet significant, impacts on the health of an individual. Muscle provides the necessary tissue for physical activity, therefore a loss of muscle reduces physical capacity. With time, the loss of muscle mass, strength and coordination increases the risks of falls. NatraGuard consists of proteins isolated from cow’s milk. Studies have been performed on muscle cells in the laboratory and in mouse models that demonstrate NatraGuard stimulates muscle cell growth and therefore may contribute to muscle strength. The aim of this project is to determine, in participants undertaking aerobic and resistance training, the dose(s) of a dairy protein extract (NatraGuard) that produce improvement in muscle strength. This new knowledge will be used to design future research studies.
