HIIT it! – Tufts

High-Intensity Interval Training has been growing in popularity, and research supports potential benefits for all ages. 

Physical activity is integral to good health. High-intensity interval training, or HIIT, is more time-efficient than traditional workouts, and research has shown it has many health benefits, including improving fitness, cardiovascular health, and insulin function, and helping with weight loss.

What is HIIT? HIIT involves performing short, vigorous bursts of activity followed by low-intensity activity or rest. This cycle is repeated for a series of sets. The high-intensity activity should get one’s heart rate up to about 70 to 90 percent of maximum. For the low-intensity period, heart rate should be about 60 to 65 percent of maximum. (A quick estimate of your maximum heart rate is 220 minus your age.) On a stationary bike, for example, a HIIT workout could be 30 seconds of pedaling at maximum effort followed by two to three minutes of easy pedaling, repeated for three to five cycles. Activities and intervals can be adapted to an individual’s current fitness level. Any activity that gets one’s heart rate up, including walking/jogging, using an exercise machine, or performing jumping jacks, sit-ups, push-ups, or squats will work.

The standard physical activity recommendation of 150 minutes of moderate activity or 75 minutes of vigorous activity weekly for good health still stands. HIIT is a type of vigorous activity that has been recognized as a more efficient alternative to traditional moderate-intensity continuous training. With a physician’s approval, HIIT can be an option for all ages and fitness levels, including individuals who are currently sedentary, unfit, or living with a lifestyle-related disease like diabetes or high blood pressure.

HIIT training can reverse aging processes in adults – Mayo Clinic

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

HIIT – High Intensity Interval Training Infographic

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.

Enjoy!

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.
