Build Muscle With Light Weights, Says Study

By Ryan Halvorson | October 19, 2010 |

Researchers from McMaster University in Hamilton, Ontario, studied 15 men as they performed four sets of unilateral leg extensions at 90% 1-RM and 30% 1-RM. The subjects were instructed to work until failure.

Slow Down Aging With Interval Training

By Amy Ashmore, PhD | August 27, 2008 |

As we age, our hearts beat more slowly and pump less blood. Our lung capacity also decreases. These changes result in decreased maximal oxygen consumption, which causes less oxygen to reach muscles. Oxygen is the life fuel for muscles; without it, they simply cannot work. The decrease in muscle oxygen consumption is one of the main reasons why we slow down, grow weak and lose stamina as we age. Without speed, strength and stamina, we cannot do the basic activities of daily living that allow us to enjoy life, maintain health and remain independent.
