Mitochondria, found in most cells, is where respiration and energy production takes place. As we age mitochondria become impaired and energy production declines. A study sought to determine if high-intensity interval training (HIIT) could reverse that trend.
Two groups did HIIT workouts for 12 weeks - men and women ages 18 to 30 and men and women ages 65 to 80. From this article about the study, High-Intensity Interval Training Helps Slow Down the Aging Process the results:
“Participants in the younger group saw a 49% increase to their mitochondrial capacity, which is what helps your body’s cells create energy. The older participants saw a 69% increase.”
HIIT workouts don’t take long, and they are effective in addressing a wide range of health issues. At New Orleans Fitness Training and Austin Fitness Training we specialize in HIIT for strength - one integrated workout combining strength training and interval training. We also have clients do interval training on stationary bikes. Past blog posts on mitochondria and a post on bike interval training.
