No, but past recommendations for older adults (note that the average age in the study was 72 years old) were towards "gentle" or moderate exercise. We're seeing a shift now towards recommending real weight lifting and higher intensity as we age. ("Real" -> closer to powerlifting in terms of goals and methods)
why is it powerlifting?
general prescription these days for Hypertrophy is 10 sets per muscle group per week 0-3 RIR.
read the study more carefully if you think it encourages powerlifting for the elders.
It says nothing about weightlifting. The high intensity training is on a treadmill. Also, "changes were small and not clinically meaningful compared with exercise of lower intensity and considering measurement error." The study is really not noteworthy and certainly not a basis for changing any population wide recommendations.
