The Secret to Longevity? 4-Minute Bursts of Intense Exercise May Help (msn.com) 82

The New York Times reports on results from a rigorous five-year study in Trondheim, Norway that raises the question: If you increase your heart rate, will your life span follow? The study, one of the largest and longest-term experimental examinations to date of exercise and mortality, shows that older men and women who exercise in almost any fashion are relatively unlikely to die prematurely. But if some of that exercise is intense, the study also finds, the risk of early mortality declines even more, and the quality of people's lives climbs...

Their first step was to invite every septuagenarian in Trondheim to participate... More than 1,500 of the Norwegian men and women accepted... All agreed to start and continue to exercise more regularly during the upcoming five years... The first group, as a control, agreed to follow standard activity guidelines and walk or otherwise remain in motion for half an hour most days. (The scientists did not feel they could ethically ask their control group to be sedentary for five years.) Another group began exercising moderately for longer sessions of 50 minutes twice a week. And the third group started a program of twice-weekly high-intensity interval training, or HIIT, during which they cycled or jogged at a strenuous pace for four minutes, followed by four minutes of rest, with that sequence repeated four times... During that time, the scientists noted that quite a few of the participants in the control had dabbled with interval-training classes at local gyms, on their own initiative and apparently for fun...

After five years, the researchers checked death registries and found that about 4.6 per cent of all of the original volunteers had passed away during the study, a lower number than in the wider Norwegian population of 70-year-olds, indicating these active older people were, on the whole, living longer than others of their age. But they also found interesting, if slight, distinctions between the groups. The men and women in the high-intensity-intervals group were about 2 per cent less likely to have died than those in the control group, and 3 per cent less likely to die than anyone in the longer, moderate-exercise group. People in the moderate group were, in fact, more likely to have passed away than people in the control group.

The men and women in the interval group also were more fit now and reported greater gains in their quality of life than the other volunteers....

Dorthe Stensvold, a researcher at the Norwegian University of Science and Technology who led the new study, believes the study's message can be broadly applicable to almost all of us.. "Adding life to years, not only years to life, is an important aspect of healthy ageing, and the higher fitness and health-related quality of life from high-intensity interval training in this study is an important finding."

        That is actualy literally a story spread by Coca-Cola PR to shift the blame from them to you. It's more than Coke. Mother Culture, in the West, says that if you're not feeling full, you haven't eaten. Most Westerners born in the past 50 years have never experienced real hunger. Mild hunger is a totally normal experience when eating 3 meals per day. But we've replaced hunger with high sugar sodas, brunch, snacks and nibbles.

        This isn't true if you're over eating. Exercise will cut in to the excess calories. Even if you increase your food intake, it might not equal the increase in calories burnt through exercise.

          In terms of intake, it's easy to see how people could do that. It breaks down to about 150 calories extra a day, and it's easy to grab a snack and a slightly larger portion of something and be looking at an extra 150 calories. "I

            It is easier if you gain more muscle mass, you automatically start to burn more calories, even when resting. Also your numbers are off. 1000 calories is easily obtainable within one training. A kickboxing lesson at my gym takes 1.5 hour in that time I already burn 1000 calories [1].

        I spent over 50 years using the sugar rush as a replacement for sleep, a panacea for boredom, and a quick fix for small cravings. It was a core response to nicotine cravings when I successfully quit smoking. No one from Coca-Cola, or anyone else, held a gun to my head at any point.

        Neither diet and/or exercise provide a long-term fix to obesity. They are the tools to get there, but, without understanding how you got here, and what habits need to change, weight loss will be temporary, if it happens at all.

        • Obesity and other disorders are often caused by mental issues. A quick burst of exercise is obviously not much of an energy burn to make a difference.

          But what it does is it gives a feeling of success and accomplishment, a short rush of adrenaline and other hormones. One such hormonal experience per day will offset your mental health leading to a more active life in general. When you do it as the first thing in the morning each day then it changes your entire attitude, outlook on life and even body posture.

        4 Minutes exercise only take about 1/6th of the sugar from your liver. That does not make hungry at all.

          Damn it! I hate it when promising studies turn out to be improperly reported.

          The graph in your linked article shows that the effect is very uncertain (and the abstract confirms). For HIIT vs Control, the relative risk with a 95% confidence interal is between 0.33 to 1.2. That is, HIIT has anything from a huge positive effect to a significant negative effect.

          I would not base any policy recommendations on such uncertain numbers and we should not exaggerate the significance of this study.

              In general, it makes it really hard to draw conclusions. There could be publication bias so that non-positive effect studies are not published which makes the average biased. There could also be differences in testing methodologies, lack of raw data etc that make averages meaningless or impossible to compute.

        From the study [bmj.com], "When MICT and HIIT were analysed separately, with the control group as reference (observed mortality of 4.7%), an absolute risk reduction of 1.7 percentage points was observed after HIIT (hazard ratio 0.63, 95% confidence interval 0.33 to 1.20) and an absolute increased risk of 1.2 percentage points after MICT (1.24, 0.73 to 2.10)." So, the confidence intervals for the relative risk for any two of the three groups includes values both less than and greater than 1.0, which basically means that the results show that not much can be concluded.

        Perhaps the general rule of comparative studies should be that whenever statistics are required to demonstrate a conclusion, the conclusion is weak.

            No, what I wrote is just an obvious statement of what everyone already recognizes. For example, an experiment where a cohort ingests arsenic versus a control group ingesting a placebo needs no confidence intervals because the difference in the counts are so stark. It's only where the differences are not obvious that confidence intervals and other statistics are stated. Compared to the stark differences, the statistical differences are relatively weaker.

      For an isolated study I'd agree with you. But this is not an isolated study. The benefits of HIIT have been studied over and over again and they all lead to the same conclusions.

      Other studies with more significant results exist but they don't look at death rate, instead focusing on health outcomes, improvements in VO2Max levels, resting hearrrate, muscle mass, etc, and they all show that HIIT produces better outcomes for the same exercise duration.

      I mean you can doubt all you want that healthier people live longer if that floats your boat.

      I took up indoor rock climbing a couple of years ago (specifically bouldering). Climbing is intense work for fairly short intervals of about the right length - three or four minutes of intense climbing to get to the top/end of the run, followed by a few minutes of rest while you belay your partner.

      I've always felt that traditional exercising - exercise for the purpose of exercise - to be tremendously boring. Bicycle machines, treadmills, stair stepping - I can't see how anyone can stand to do that for any length of time.

      • Agreed, old timey trades are a nice way to get some exercise without it being so boring. Woodworking or blacksmithing with old fashioned tools and techniques would've been backbreaking in the old days, but if you're just doing it for fun before getting back on the keyboard to earn your keep it is pretty relaxing.

I quite frequently use a bicycle machine or a treadmill, (when I can't go for a jog or a cycle like today where it's belting down rain). I combine it with something else. I never run without music, and the run turns into just a session where I get to forget the world and rock to some beats. The music comes first and I typically run to the beat of the music.
