Aging, Fitness, and Marathon Times in a 91 Year-old Man Who Competed in 627 Marathons.

Aging is associated with a decline in maximal aerobic capacity (VO) that may be attenuated by chronic endurance exercise. This case study chronicles the changes in marathon times in a 91 year old man who completed 627 marathons and 117 ultramarathons over 42 years. He began running marathons at age 48.

The short physical performance battery as a predictor of functional capacity after stroke.

Background: The short physical performance battery is a widely used instrument for quantifying lower extremity function in older adults. However, its utility for predicting endurance-based measures of functional performance that are more difficult to conduct in clinical settings is unknown. An understanding of this could be particularly relevant in mobility impaired stroke survivors, for whom establishing the predictive strength of simpler to perform measures would aid in tracking broader categories of functional disability.
