"If that stubborn body fat isn't going away, consider adding High-Intensity-Interval-Training or HIIT to your exercise routine," says Professor Zeljko Pedisic of Victoria University, Melbourne. HIIT increases fat burning more than aerobic exercise, finds a study published in the British Journal of Sports Medicine. How was the study conducted? Authors of the study pooled results from 18 controlled intervention trials on the effects of HIIT on the rate of fat burning during exercise. The intervention trials included a total of 511 adult participants who were engaged in supervised HIIT, moderate-intensity aerobic exercise, or a non-exercising control group. The duration of...

Researchers at McMaster University who examine the impact of exercise on the brain have found that high-intensity workouts improve memory in older adults. *snip* Researchers suggest that intensity is critical. Seniors who exercised using short, bursts of activity saw an improvement of up to 30% in memory performance while participants who worked out moderately saw no improvement, on average. *snip* For the study, researchers recruited dozens of sedentary but otherwise healthy older adults between the ages of 60 and 88 who were monitored over a 12-week period and participated in three sessions per week. Some performed high-intensity interval training (HIIT)...

Exercising just 10 minutes every other day may reverse the effects of aging Fitness marketers often use extreme language (“Breakthrough!” “Miraculous!”) to describe the latest hot workout or gear. But scientists and doctors are now using superlatives to discuss what many consider to be one of the most important new fitness approaches in decades: high-intensity interval training, or HIIT, an approach to exercise that people can do in relatively little time, but with oversize benefits. If you ever did wind sprints in high school, then you know what HIIT is — brief bursts of very intense exercise followed by periods...

The fountain of youth just might be filled with sweat: Certain types of exercise can help you age better, new research published in the European Heart Journal suggests. In the study, researchers enrolled 266 young, healthy participants who were generally inactive. Then, they split them into four groups: an endurance training group, a HIIT group, a circuit-based weight lifting group, and a sedentary control group. The three exercise groups performed 45-minute sessions three times per week (the control group continued doing what they were doing, which, well, wasn’t much). At the end of six months, researchers looked at the lengths...

Video LinkThe title of this video is misleading, but it is a very interesting video. We have all heard of the benefits of high intensity interval training but this video takes it a little further.It takes a woman who is in sort of average condition and has her undertake a high intensity program of 3 workouts a week. In each workout she does 4-30 second sprints with each sprint followed by a rest period. The producers get the 6 minutes a week from the sprint periods (4 at 30 seconds equals 2 minutes of course times 3 workouts a week)....

It’s long been known that physical activity can reduce inflammation in your body and improve heart health. This study recently published in cell.com shows that High-intensity interval training (HIIT) is more effective than weight training or cardio for improving metabolic health, is superior for fighting age related decline, and may yield anti-aging benefits down to the cellular level. HIIT was found to be even more effective at improving mitochondria biogenesis in older individuals. “HIIT reversed many age-related differ- ences in the proteome, particularly of mitochondrial proteins in concert with increased mitochondrial pro- tein synthesis.” “HIIT increased maximal absolute mitochondrial respiration...

Many of us have tried high-intensity interval training (HIIT) at some point, even if it was just a boot-camp class our friend dragged us to. But a new study suggests that we may want to incorporate those workouts — which include short bursts of intense exercise, followed by stretches of more moderate activities — into our regular fitness routines, since they’ve been shown to reverse the aging process. Published in the journal Cell Metabolism, scientists from the Mayo Clinic recruited an equal number of women and men to participate in the study, and split them up into two groups: young...
