Try High-Intensity Interval Training. You Might Like It.

Supervised lab sessions are not a good reflection of real-life exercise, however. So, as a final step in the study, the researchers asked the volunteers to go home and work out on their own for a month, keeping exercise logs, then return to the lab to talk at length with the researchers again.

This month of do-it-yourself workouts proved to be revealing. Almost everyone remained active, with most completing frequent, moderate exercise sessions, like the 45-minute bike rides at the lab. But many also threaded some sort of interval training into their weekly workouts, although few of these sessions replicated the structured intervals from the lab. Instead, people tended to sprint up and down stairs or grunted through some quick burpees and other body weight exercises.

Most interesting, during their subsequent, prolonged interviews with the researchers, the volunteers who interval trained on their own said they felt more engaged and

High-intensity interval training benefits older people

Five years of high-intensity interval training increased quality of life, improved fitness and might very well have extended the lives of participants in the Generation 100 study.

First of all, I have to say that exercise in general seems to be good for the health of the elderly. And our study results show that on top of that, training regularly at high intensity has an extra positive effect.”

Dorthe Stensvold, Professor, NTNU

Stensvold is a professor in the Cardiac Exercise Research Group (CERG) at the Norwegian University of Science and Technology (NTNU) and has been looking forward to sharing the results from the Generation 100 study for a while now.

Researchers, healthcare professionals and individuals around the world are eager to learn the answer to the question: Can exercise really give older people a longer and healthier life?

More Evidence of Interval Breast Cancers’ Aggressive Nature

Women diagnosed with interval breast cancers — those detected between routine screenings — had a higher risk for aggressive disease and death, a restrospective study in Canada indicated.

Among women participating in a national screening program, and with a median follow-up of 7 years, breast cancer-specific mortality was more than threefold higher for women diagnosed with interval breast cancers compared to those whose cancers were found on screening, which included a sojourn time of 2 years to account for lead-time bias (hazard ratio [HR] 3.55, 95% CI 2.01-6.28, P<0.001), reported Saroj Niraula, MD, MSc, of the University of Manitoba in Canada, and colleagues.

The findings highlight the differences in the natural history of these cancers “and highlights inadequacies in current breast cancer screening practice,” the group wrote in JAMA Network Open. “Many of the aggressive and lethal forms of breast cancers either go unnoticed on mammogram or develop
