The correlation | between grip and survival is probably solid enough, but it's hard | to avoid the nagging feeling that people who have a strong grip | are probably stronger and healthier overall as well. | | The article goes on to recommend grip strengthener and I strongly | suspect that better skeletal-muscular health in general should be | the goal. | | "Strong people are harder to kill than weak people and more | useful in general." --Mark Rippetoe. | mancerayder wrote: | The correlation is probably between strong wrist muscles and | general fitness, i.e. exercise or strength training, and | longevity. | igouy wrote: | "Correlation does not imply causation." | kayodelycaon wrote: | But it does get lots of views. ;) | dugditches wrote: | While the website seems very fluff, the concept of hand health | can't be overstressed. | | Keep care of your hands and wrists. If you feel pain or | discomfort, stiffness etc figure out why and fix it. Whether it's | keyboard/desk etc change. Or taking breaks and stretching. | | Those suffering later stages of hand/wrist strain or wear... look | into: wrist straps, wax baths, heated 'wax gloves' | brimble wrote: | OK, maybe there's something to being able to catch yourself when | falling, or prevent the fall in the first place through grip | strength. But this: | | > It's not just bracing yourself. Scientists have linked stronger | hands to healthier hearts. | | > One study in the American Journal of Preventive Medicine found | that higher grip strength was correlated to lower blood pressure, | lower blood sugar and higher good cholesterol levels. | | _Has_ to just be grip strength correlating with activity level | and general health, not grip strength _causing_ any of that. | robocat wrote: | https://www.reddit.com/r/dataisbeautiful/comments/4vcxd0/alm... | | Submitter said: "EDIT 2: Some of the very low values are | individuals with disabilities", "EDIT 4: Grip strength is a | decent proxy for upper and lower limb strength, and is also | correlated with other indices of strength." | [deleted] | scythe wrote: | Well, it doesn't have to be that abstract. Muscles in the | peripheral limbs, particularly the lower leg but also the | forearm, are important in returning venous blood to the heart. | In fact, the gastrocnemius (calf muscle) has been referred to | as the "second heart": | | https://veinatlanta.com/your-second-heart/ | avalys wrote: | I am going to bookmark this article as a classic example of | reporting so ill-informed that it confuses cause and effect, as | described by Michael Crichton in characterizing "Gell-Mann | Amnesia." | | https://www.epsilontheory.com/gell-mann-amnesia/ | | https://en.m.wikipedia.org/wiki/Michael_Crichton#GellMannAmn... | cooervo wrote: | /r/hailcorporate this guys are just promoting some products | backed with pseudo science BS | DrPhish wrote: | That would definitely explain the large numbers of feisty old | Judoka I meet around the world. Anecdotally, there seems to be a | higher percentage of healthy older individuals doing Judo than | the general population, but I guess the unhealthy ones wouldn't | still be at it, so it self selects for that trait. | | Judo practitioners might be a good population to study for this | effect, if you could find the individuals that started and track | them all, including the dropouts. It would have common traits of | strong grip AND muscle memory of how to fall properly, which | could be a confounding factor. | credit_guy wrote: | Also, playing golf adds 5 years to your life expectancy [1]. I | kid you not. Start playing today, and you'll live years longer. | This has nothing to do with the fact that most golf players are | really wealthy, and so they have access to way better healthcare, | nutrition, and lifestyle than the rest of us. | | Said differently, correlation does not imply causation. | | [1] https://www.golfandhealth.org/news/golfers- | longevity/?amp_ma... | baal80spam wrote: | Love it! | treeman79 wrote: | Decided to take up golf. Now I can't feel my leg. | cperciva wrote: | They claim that was adjusted for socioeconomic status. | | Rather than being a matter of better access to health care etc, | I suspect a reverse causation -- people who are in poor health | are less likely to go out to the golf course. The same applies | to Vitamin D, taking international flights, and reading books, | all of which are correlated with reduced death rates. | qiskit wrote: | Thank you. They always make it sound like X helps you lenghten | your life. But it's always the case the X is a symptom of a | healthy life, not the cause of it. | | Strong hands is probably a result of exercise and leading a | healthy life which leads to higher life expectancy. Meaning | exercise and leading a healthy life is the cause of strong | hands and higher life expectancy. | | Golf industry says golf lengthens your life. Hand grip industry | says strong hands lengthen life. Can't help but be a little bit | cynical the older I get. | rufus_foreman wrote: | Here's a metastudy of 26 studies of the results of handgrip | training on systolic blood pressure: | https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6292032/. | | The results were that handgrip training for at least 4 weeks | reduced blood pressure by around 5 mmHg. Which yes, could | lengthen some lives. | | Assuming that correlations are spurious is as poor an approach | as assuming they are not. | tj-teej wrote: | Bob: "You know I used to think correlation implied causation, but | I took this Statistics class but know I know that's not true." | | Jeff: "Wow it sounds like that class really helped you" | | Bob: "Maybe!" | | Credit goes to XKCD | gurjeet wrote: | Previous discussion: | https://news.ycombinator.com/item?id=30716390 | WalterBright wrote: | I can hang two handed on a bar, no problem.
