Another group started moderate exercise twice a week in a long 50-minute session. And the third group started a program of high-intensity interval training (HIIT) twice a week. In the meantime, they cycled or jogging at a vigorous pace for 4 minutes, then rested for 4 minutes, and repeated the sequence four times.
Almost everyone continued their assigned exercise routine for five years, eternal in science, and regularly returned to the lab for check-in, testing, and supervised group workouts. Meanwhile, scientists have noticed that a significant number of control participants, on their own initiative, have taken part in interval training classes at a local gym, apparently for fun. Other groups did not change their routine.
Five years later, researchers checked the death registry and found that about 4.6% of the original volunteers died during the investigation. This is less than Norway’s wider population, 70, and these active older people, overall, live longer than others of their age.
However, they also found a slight but interesting difference between the groups. Men and women in the high-intensity interval group were about 2% less likely to die than the control group and 3% less likely to die than anyone in the longer, moderate exercise group. In fact, people in the moderate group were more likely to die than people in the control group.
Men and women in the Interval Group are now also healthier and report a significantly improved quality of life than other volunteers.
In essence, Dorte Stensbold, a researcher at the Norwegian University of Science and Technology who led the new study, said that intensive training, which was part of both interval and control group routines, was more for premature death than moderate training. Alone who says it provided slightly better protection.
Of course, she added that exercise was not a panacea. Some people still died of illness, whatever their training program. (No one died during exercise.) This study also focused on Norwegians, who tend to be unnaturally healthy, and perhaps unfortunately most of us are not Norwegians. .. Also, you may not be in your 70s yet.
However, Dr. Stensvold believes that the message of this study is widely applicable to almost all of us. “We should strive to include high intensity exercise,” she says. “Intervals are safe and feasible for most people, and adding life to life for years, not just years, is an important aspect of healthy aging, and HIIT in this study. Higher fitness and health-related quality of life from is an important discovery. “
