Grantee in the News: Bruce Troen on high-intensity interval training reduces frailty in older mice in NY Times View MoreBACK

On July 12, 2017, The New York Times featured research by 1990 AFAR Research Grant recipient, Bruce R. Troen, MD in an article, High-Intensity Workouts May Be Good at Any Age. The Times’ piece spotlights a study co-authored by Dr. Troen in The Journals of Gerontology.

The original study, High Intensity Interval Training (HIIT) improves physical performance and frailty in aged mice, observed sedentary mice that were the rodent equivalent of about age 65 in humans. These mice were administered 10-minute uphill treadmill HIIT sessions three times per week over 16 weeks.

The researchers found that muscles from these mice had greater mass, larger fiber size, and an increase in mitochondrial biomass.

Researchers saw a dramatic improvement in grip strength, treadmill endurance, and gait speed as well.

The study also found dramatic performance gains, improvement in underlying muscle physiology, and reduction in frailty.

Despite their older age, “the animals had tolerated the high-intensity interval training well,” Dr. Troen told the NY Times.
