Eat less; move more; live longer remains the mantra of this blog. So, I was thrilled to read this latest from the Mayo Clinic on High Intensity Interval Training (HIIT).
Everyone knows that exercise is good for you, but what type of training helps most, especially when you’re older – say over 65? A Mayo Clinic study says it’s high-intensity aerobic exercise, which can reverse some cellular aspects of aging. The findings appear in Cell Metabolism.
Mayo researchers compared high-intensity interval training, resistance training and combined training. All training types improved lean body mass and insulin sensitivity, but only high-intensity and combined training improved aerobic capacity and mitochondrial function for skeletal muscle. Decline in mitochondrial content and function are common in older adults. Continue reading
I picked this up from an email and was impressed with how inclusive it is. I think I now know twice as much about High Intensity Interval Training as I did before I read it.
On the subject of HIIT, the September 12, 2016 issue of Time magazine says, ” Martin Gibala, an exercise physiologist at McMaster University wanted to test how efficient and effective a 10-minute workout could be, compared with the standard 50-minutes-at-a-time approach. The micro-workout he devised consists of three exhausting 20-second bouts of all-out, hard-as-you-can exercise, followed by brief recoveries. In a three-month study, he pitted the short workout against the standard one to see which was better.
To his amazement, the workouts resulted in identical improvements in heart function and blood-sugar control, even though one workout was five times longer than the other. “If you’re willing and able to push hard, you can get away with surprisingly little exercise,” Gibala says.
