I’m genuinely confused. Was there any doubt before this study that sport makes people healthier?

There was plenty of obvious, common sense assumptions that didn't hold at all when methodically tested, like sugar rush in children. And this specific type of studies tries to find a sweet spot between benefits and effort taken. Some results were unexpected, If I recall correctly on found that having to take three flights of stairs daily outperformed many exercise regimes designed for elderly.

No joke. I go to the gym a couple times a week so that I'll maintain mobility and won't injure myself as I age - unfortunately 80% of my injuries come from the gym.

If most of your injuries come from the gym, I recommend you get a trainer.

80% of my injuries occurred while sleeping, which seems very weird.

I have met people who figured, because they don't excercise they don't wear their body out, so their joints etc. will last longer. Same for injury, no sport no injury, that must be good!

Earlier quoted context omitted.

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.

Hypertrophy and strength aren't as strongly linked as we thought. Generally for wellness, injury prevention, you want strength and flexibility.

Sports and exercise are definitely beneficial, but any sort of activity presents a risk of injury.

If people work out, or play sports, without knowing proper form, without using protection or precautions, they'll get injured and then worse off than before. Realistically, manual laborers should be in real good shape, but often their jobs are so low-wage, and they're so interchangeable, that safety precautions are ignored and must be regulated/enforced.

I took up roller skating and was rewarded with a broken leg. I took up gym exercise and was repaid with a hernia. Both required surgery. No regrets! Only wished I could've better understood how to exercise safely!

I once encountered a FB group that was for people to discuss "sports injuries sustained while we were in bed" and I could totally relate, having done weird stuff to my shoulder overnight, rather than pitching a baseball game...

There are plenty of high intensity activities with low risk of injury. Rowing and swimming come to mind.

I think the bigger problem is that, as far as I can tell, very few people have the appropriate personality type for high intensity exercise. Most people seem to experience it just as pointless discomfort.

Really depends on how you define high-intensity. To build muscle, you need to push yourself to a limit. You can reduce the weight and increase the repetitions. This approach is just as effective and lowers the risk of injury.

This is what I do. When I was beginning with weight training, I followed other's recommendations back then and pushed hard. Had quite often minor issues or injuries in the joints which set me back for weeks or even months, my tendons seem to be my weak spot and it does get worse with age, both limits and recovery.

Lowered the load, increased repetitions and basically nothing for a decade. I can still go almost to the failure, I don't even want to reach it since I don't care about that extra bit. Squats or deadlifts are hard even when not at limits, one feels used body parts for a day or two.

I still add cardio on top of that, its just basic logic of moving around a lot is very good for the body, even if effects are not immediately obvious.
