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

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)

read the study more carefully if you think it encourages powerlifting for the elders.

This is highly unusual. You shouldn’t be injuring yourself that frequently at the gym, especially if your goal Is just to maintain mobility and basic muscle mass as you age. This is such a strange thing to hear, as someone who also has gone to the gym a couple times per week for my life with a lot of different gym buddies. I would suggest considering a reset of your gym routine and gym knowledge, possibly with the he…

Only the 80% number was given. If he has been going to the gym for 30 years and had 5 injures at the gym, one outside that would be incredibly low for a total, and that level of carelessness at the gym is lower than I'd expect. If his routine was over 1 month then there are big problems.

Getting injured at the gym shouldn’t be such a problem that someone has to mention it.

You don’t need to be pedantic about the 80% number.

So warning about super-high intensity workouts. For a good while I would sprint hard as possible up 8 flights of stairs everyday instead of taking the elevator. I would do this multiple times per day (3,4 sometimes 5) with no warm-up/cool-down . Each time I would try to push for a PR, figuring might as well go for it! One day, after about a year of doing this, I noticed my heart rate at the top felt a little off. I tested with my watch and it said I was in AFIB. I was able to get back to normal sinus rhythm via getting zapped at the ER, but ever since then if I push too hard (usually on longer runs, going all out) I end up back in AFIB. Though it will reset the next morning.

This could be pure coincidence, but I would recommend doing proper warm-up and cool-down before going all out with HIIT. FYI I'm in my 40's.

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.

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

The neck is quite vulnerable during sleep and could lead to neck muscle injuries that leave one with a stiff neck for days.

> “High-intensity training reduced fat and maintained lean mass […] though changes were small and not clinically meaningful compared with exercise of lower intensity…” High intensity does border on leading to injury — just making the wrong move — and you’re back to zero intensity?

Calisthenics is a really easy way to push intensity at basically 0 risk of injury. They're all compound and depending on the variation could require high reps, but between push ups, pull-ups, squats, their numerous variations, and accessory work, I would challenge anyone to actually injure themselves while also being able to push to true technical failure.

Poor form is possible with calisthenics and that leads to injuries or other problems.

I think it's important to note that this study, at least to my understanding, compared cardio training - not weightlifting or resistance training. Participants did 3 weekly sessions of either low intensity, moderate treadmill excercise or HIIT ( 4-min @ 85–95%, 3min 60-70% ). I get the feeling some commenters here are misunderstanding this as a lot of the discussions seems to center about weightlifting. Additionally…

can you tldr me if weightlighting will put me roughly in the "hiit" group discussed in the paper, and give me its benefits?

My experience is that every movement pattern causes "injuries" like a sore tendon, wrenched back, inflamed shoulder that surface with every 20 pounds of added weight until I figure out what about my form is incorrect. Usually not something a trainer would see like "don't flare your elbows", internal stuff like "use your glute medius to help push" or "elbows in line with the torso on squats" that might be in 1 of 20 YouTube videos.

I use the weight training to surface the injuries to make me aware of what I'm doing wrong in daily movements. I might finally be past this and able to just go in and push weights but it's taken years. I feel like it's down to the body I'm living in and what I consider a pain threshold, not any risk taking or lack of information.

This study followed everyone for 6 months so they probably got past that factor.

I doubt it. In my experience (at least when it comes to lifting), newbie gains last at least a year. Good chance that if they've been untrained all their life (or the majority of it) that phase is gonna last a real long time.

A year of continuous gains for a 72 year old? I highly doubt it. For a skinnyfat 20 year old, sure.

HIIT is a borderline strength training. Consider Tabata protocol. It is supermaximal effort protocol, participants are required to exert maximum effort repeatedly. The duration of active phase of Tabata is 20 seconds, half of approximately 40 seconds after which maximum performance (power output) drops significantly, because body switches to a different energy system. In my experience, Tabata squats are done in range…

Tabata is the craziest workout ever, with Tabata sprints I couldn't feel my legs 3 minutes in and after 4 minutes all I could do was to vomit while shaking on the ground. 7-minute workout with as many reps as possible (even if not in perfect form) helped more overall.

> average age 72.0 years, body mass index 25.8 Careful before you assume you'll have the same outcomes. That's a group of people who are already fairly light compared to the American populace, and likely are suffering from sarcopenia of sorts and have low potential to gain much more muscle. (Protein absorption, hormone profile) > Dietary intake was assessed using a 3-day food diary at baseline and analysed for total…

Erm that's higher than the healthy BMI range, so not "fairly light". >25 is considered overweight.

It's still lighter than the average American BMI, which is around 29. On average, Americans are classified as overweight.
