A nice article in the August issue of the International Journal of Sport Nutrition and Exercise Metabolism titled Effect of creatine supplementation and resistance-exercise training on muscle insulin-like growth factor in young adults looked at the effects on Insulin-like Growth Factor-I (IGF-I) levels in people combining 30 minutes of exercise 3-5 times per week with [...]

A new study to be published in the Journal of Applied Physiology has confirmed that exercise can restore the decline in neural stem cells normally associated with aging.
The brain constantly produces new cells that differentiate into a wide variety of mature neurons in a process called neurogenesis. Particularly in the hippocampus, a decline in the [...]

A study presented at the American Association for Cancer Research’s Seventh Annual International Conference on Frontiers in Cancer Prevention Research has shown that physical exercise decreases cancer risk, but only if it’s accompanied by sufficient nightly sleep.
The study looked at 5,968 women at least 18 years old with no previous cancer diagnoses.

Research today coming out of Journal of the International Society of Sports Nutrition and brought to my attention by Eurekalert suggests that supplementation with beta-alanine improves muscle endurance in the elderly.
Beta-alanine is the rate-limiting precursor to carnosine, which is to say that levels of carnosine are limited by the available beta-alanine.
Supplementation with beta-alanine has already [...]
