I hate how much the authors of this article imply causality. >There also, interestingly, was less activity among the runners in a part of the brain that tends to indicate lack of focus and mind wandering. Could it not be that people who have the willpower to run regularly also have the willpower to stay focused? >In essence, the runners seemed to have brains in which certain cognitive skills, including multitasking and concentration, were more finely honed than among the inactive men. "Honed" definitely implies that running hones those skills, when in fact having those very skills could be a confounding factor. All of that said, I have yet to see a compelling argument against running regularly.

There are plenty of compelling arguments against excessive running: 1) It is destructive to your joints and tendons. Injury rates are very high among runners. 2) It is stressful, resulting in chronically elevated cortisol levels. 3) It is time consuming and boring (of course this is subjective), and very inefficient at improving fitness.

    - notacoward 10y ago
      No, we don't. I'm not sure even the author has a clear definition of "excessive" in mind, so we might not know even if we were all telepathic. The validity or applicability of their complaints about running is very closely tied to that definition, so it's entirely reasonable to seek clarification.

  Pretty sure there have been studies positively correlating running a certain amount with dying younger. I can't imagine sucking in city pollution can be that healthy either. Anecdotally, it helps my anxiety.
  - AJ007 10y ago
    There is a tendency, from what I've observed, to use running as a way to have a really bad diet and still stay thin. There is a lot of pressure for people in their 20s and 30s who live in urban areas to both look fit and drink heavily. Not a good recipe for long term health.

        Restricting calorie intake.
        hueving 10y ago
        It takes hours of running to offset a couple of beers worth of calories. If you're eating unhealthy and drinking a lot, there is no amount of running to undo it.
        dajohnson89 10y ago
        A beer is, say, 150 calories. A mile of running burns about 100 calories. When I ran, cruising speed was 7 minutes per mile. So a light 6 mile (10k) run would be about 45 minutes, 600 calories, or 6 miles.
- notacoward 10y ago
  Anything done excessively can be unhealthy, by definition, but there's only a grain of truth to what you're saying. To your point 1: done properly, running isn't particularly harmful to joints and tendons, and some studies even seem to show that running can be beneficial in that regard[1]. The rapid changes in direction that cause the most stress are less prevalent in running than just about any other sport, not even considering the impacts that can occur e.g. in contact sports. Injury rates are not particularly high in running compared to other sports, and even if that were so you should be careful about confusing correlation with causation. A lot of people get injured while running mostly because it's an incredibly popular form of exercise. Do you seriously think there would be fewer injuries e.g. among the same number of people playing rugby? To your point 3: I know a lot of weight-training addicts like to make that claim, but it's just not true for any reasonable definition of fitness. Running isn't particularly good for weight loss, but weight loss has little to do with fitness. Ditto for weight gain, even in the form of muscle. When it comes to the kind of fitness that actually matters - i.e. developing one's heart and lungs to prevent the chronic problems that kill millions every year - only a few kinds of exercise are better than running. Swimming, rowing, and cross-country skiing come to mind. There are probably a few more, but lifting weights is certainly not on the list. You personally don't like running? Fine. No exercise is ideal for everyone. But spreading FUD that discourages others from pursuing a healthy habit doesn't seem very constructive. P.S. Instead of getting your friends to downvote, how about suggesting an actually-healthy alternative?

      I had 2 herniated discs (L4-L5, L5-S1) in 2014 due to swinging an axe over my head for an extended period of time on a large structure fire. I say that to say this; running is way better for my back than cycling. My left leg, mostly my foot, still haven't completely recovered from the nerve impingement, but I am running 30 to 40 miles a week with no problems (lots of trail running too, check my Strava :) ) I can't cycle like I used to on any "normal" bicycles. This position, bent at 90 degrees or more, that one is required to sit while cycling is actually pretty terrible for the lower back. Also, being male and being part of a large male dominated industry - firefighting, I see lots of male cancers. That is, testicular and prostate cancers. My department is participating in a massive testicular and prostate study; We are being asked to change our chonies often and wash hands before going to the bathroom as the scrotum is a sponge for anything it touches... smashing that region when cycling for extended periods of time seems like a bad idea (and it hurts).

  This data still isn’t perfect, but it adds another brick to the growing pile suggesting that running will not ruin your knees.[1] New study explores how exercise may fight joint inflammation[2] [1]http://www.runnersworld.com/sweat-science/run-for-your-knees http://www.runnersworld.com/sweat-science/run-for-your-knees [2]http://www.runnersworld.com/sweat-science/is-running-actually-good-for-your-knees http://www.runnersworld.com/sweat-science/is-running-actuall...

  2) Your premise is true but your conclusion is wrong: while cardiovascular induces an aroused state and increases cortisol levels, it is also conditioning the body to be able to quickly return to a resting state, so when it is aroused at a later time (from a stressful encounter with a coworker for example), it will spend less time in that state because it recovers faster.
- nabla9 10y ago
  1) The idea that running is bad for your knees and joints is a popular fitness myth. According to several studies runners, even those who have run competitively for many years, do not have an increased prevalence of osteoarthritis. 2) Chronically elevated cortisol levels are result of overtraining. If you do that, you are doing it wrong. Overtraining happens when a person experiences stress and physical trauma from exercise faster than their body can repair it. Overtraining is not same as training a lot. Gradually increasing the running time and having enough rest days prevents that while the running distances grow. 3) You get runners high and it's not boring. Of course there are people with conditions that get worse with running. Fat people should start slowly.
  - CJefferson 10y ago
    The knees is still out. One problem with studying long term runners, I'd often people who get knee pain drop out. That's me -- went to various physios, they all agree I've messed up my knees, and won't ever recover enough to take up running again.
    - dspillett 10y ago
      Like the back problems sometimes associated with rowing, a lot of knee issues from running are due mainly to bad form. If you over-stride, particularly down-hill (and going "too fast" down hill instead of managing your pace/stride is a recipe for over-striding) the knees will be too straight during impact and so experience excessive impact force (and therefor potential damage) that would otherwise be absorbed by muscles/tendons/elsewhere.
      - CJefferson 10y ago
        While form is important, it doesn't fix fundamental joint problems unfortunately. I was checked fairly carefully by a couple of NHS physios, who both agreed it was joint problems, not bad form.

  > It is time consuming and boring Not for me. Mentally, it's the most productive part of my day. I "zone out" and work on problems that I haven't solved yet. Most design issues I work out while running, I write papers while running, I put together presentations while running. Many, many perplexing bugs I've solved while out for a run. Of course, I've been running for decades. When I started out, it was time consuming, painful, and boring. It took maybe 5 years for that to change into what it is now - I look forward to it, I enjoy it, and it works for me. Also, switching from a heel-strike gait to a ball-strike one has eliminated the knee pain.
  - Humdeee 10y ago
    I will never argue it's not time-consuming. Last year, I trained for 4 marathons and logged over 2000km of mileage. I don't want to think of the time that went into it, but I had a great time. The lonely "boring" runs I interpret for myself as a way to disconnect from the world and just zone out. Running with a group or with music curbs this greatly. All sports have a bit of injuries, but those who last are those who take care. Changing shoes every 500km or so, foam-rolling muscles and joints, not running through pain, etc. Proper nutrition (during longer runs AND as a lifestyle) also helps immensely. Slowly optimizing your gait, cadence, and varying your weekly training so you have those back-off weeks for recovery. These are what keep you on your feet. Here's my kicker that throws people off. I would rather watch a marathon on TV with full commentary than any other sporting event. I love it and follow the scene pretty closely. And this is coming from a guy who played professional soccer in his early 20's.

    Body weight exercises such as pull-ups, sit-ups, and push-ups are the best for fitness.
    - tempestn 10y ago
      Again, this depends on how you define both "best" and "fitness". What's best depends a lot on what someone enjoys. I would rather do an activity I enjoy for 40 minutes than get the same benefit doing something I hate for 20. Likewise, fitness means different things to different people and at different times. You may be focusing on cardio-vascular fitness, or on strength, or speed, or weight loss, or performance in a particular sport...
      - throwanem 10y ago
        Or, you know, "do something". Throwing a bunch of complexity and equipment cost at someone who doesn't currently exercise at all isn't likely to help anything much. Pushups and situps require only a clear stretch of floor.
        tempestn 10y ago
        Sure! If you're just getting started and can stick with that, maybe that's best for you! Just not for everyone.
    - paulddraper 10y ago
      I think calisthenics are great, but they focus more on muscular strength than cardiovascular. There are only so many push-ups you can do before your muscles are fatigued. Running, swimming, and cycling are better for cardio because you can do them for great lengths of time.

- dspillett 10y ago
  >* It is time consuming and boring (of course this is subjective)* Very very subjective... > and very inefficient at improving fitness Depends on what your fitness goals are. It is pretty effective at maintaining cardiovascular capability but doesn't do much for overall strength or, on its own, weight management. Anecdotal data point: as a regular runner, 10K in <42m, half marathon in <1h50, I have a cracking set of legs and lungs but my upper body is pretty weak, my core strength "fair-to-middling", and I still carry a little more than I might like around the waist. The trick to overall fitness, and something I could benefit from addressing, is to not concentrate on just one thing. Mixing running with body-weight exercises (push-ups, pull-ups, crunches, dips, ...) is generally considered a good minimal-equipment combination. For "bulking" or faster muscle strength gains add in some weights. For weight loss: eat less (or, for a more nuanced approach, eat better).
- agumonkey 10y ago
  3) is extremely subjective. I have a love for running. You can say it's repetitive, dull, hurtful .. and I'd agree totally. I was extremely ill last year, couldn't even jog; the first time I could sustain mild jogging I cried of happiness. I love all kinds of sports, biking, skating, soccer, tennis, badminton you name it. Yet running has a special wire in my spine. When you're in flow, you feel like flying, it's a bit surreal. I'm not a regular runner anymore and I can't have long periods like these but still.
- chrisan 10y ago
  > 3) It is time consuming and boring (of course this is subjective), and very inefficient at improving fitness. Whether you run, bike, hike, swim, row, or whatever it doesn't have to be boring. Running/biking on a rural Midwest road IS insanely boring alone. I frequently listen to audiobooks or podcasts either educational or entertainment and that boring road becomes something I look forward to. The times I elect no audio I use it to think on hard problems I am trying to solve or plan for These eliminate your counters of time consuming and boring. Regarding the inefficiency, you can do cardio that isn't running if you believe running is bad for you. I listen to the same thing during strength training

There are several studies that show adult neurogenesis from aerobic exercise, particularly running, in rats and mice. Example: Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained. https:/www.ncbi.nlm.nih.gov/pubmed/26844666 A review article here: https://www.researchgate.net/publication/5566493_Neurogenesis_and_Exercise_Past_and_Future_Directions https://www.researchgate.net/publication/5566493_Neurogenesi... There is at least one study that allows us to infer that the same effects may occur in humans (quoted below). Please let us know if there are more studies like this. It looks like a very practical approach to improve your cognition and prevent dementia with little risk. From: http://www.dana.org/Publications/Brainwork/Details.aspx?id=43678 http://www.dana.org/Publications/Brainwork/Details.aspx?id=4... "Columbia neuroscientist Scott Small and colleagues appear to have found a way around this problem. First, they put mice that had been running voluntarily for two weeks into a magnetic resonance imager to map exercise-induced changes in cerebral blood volume, a measure of increased blood vessel formation in the dentate gyrus. Then, by sacrificing the animals and counting new neurons, they were able to correlate the neuronal proliferation they observed with changes in blood volume. The researchers then conducted magnetic resonance tests on a small group of middle-aged people who had been exercising about an hour a day, four times a week, for three months. By charting exercise-induced changes in cerebral blood volume in the human hippocampal region and applying the same algorithms used in the mice, they were able to deduce that neurogenesis was also occurring in the humans. Changes in blood volume in the dentate gyrus, they concluded, provide a correlate of neurogenesis in humans." Anecdotal, yet may not be completely coincidental: Alan Turing was an avid marathon runner. This is not part of the argument--so please don't take it into account when responding. ;)
- tachim 10y ago
  That first study does not support your claim. This is the main chart: https://i.imgur.com/pTFJkaJ.png https://i.imgur.com/pTFJkaJ.png. Note how it shows a significant response in Doublecortin+ cells only in the HRT group and not for the LRTs. These acronyms stand "for low (LRT) and high (HRT) response to aerobic exercise training". In particular, quoting from the article: Starting with a founder population of genetically heterogeneous rats (N/NIH stock), we applied two-way artificial selection based on the magnitude of change in running capacity after completing 8 weeks of standardized aerobic treadmill training. After 15 generations of selection, rats bred as HRT increased maximal treadmill running distance from 646 to 869 m (change, 223 ± 20 m), whereas rats bred as LRT decreased from 620 to 555 m (change, −65 ± 15 m) after completing the same absolute amount of training (Koch et al. 2013). This is a huge confounding variable. There is a very good chance these cells have an impact on these rats' ability to run long distances after training, so it's completely reasonable to expect that the cell growth would respond well to the very exercise the rats were selected for responding well to! It does not show that the same effect would happen in a normal rat (the LRT rats did not see a difference in this particular cell growth, but they were also nonrandom).
bryanrasmussen 10y ago

>Could it not be that people who have the willpower to run regularly also have the willpower to stay focused? This is just an anecdote, of course, but I notice a major boost to my ability to concentrate, avoid distractions and think after a good aerobic exercise session. My efficiency goes from <1 hour of intellectual work done in a day to >4. The boost lasts about 2 days, after which the lethargy sets back in.

3) is extremely subjective. I have a love for running. You can say it's repetitive, dull, hurtful .. and I'd agree totally. I was extremely ill last year, couldn't even jog; the first time I could sustain mild jogging I cried of happiness. I love all kinds of sports, biking, skating, soccer, tennis, badminton you name it. Yet running has a special wire in my spine. When you're in flow, you feel like flying, it's a bit surreal. I'm not a regular runner anymore and I can't have long periods like these but still.

> 3) It is time consuming and boring (of course this is subjective), and very inefficient at improving fitness. Whether you run, bike, hike, swim, row, or whatever it doesn't have to be boring. Running/biking on a rural Midwest road IS insanely boring alone. I frequently listen to audiobooks or podcasts either educational or entertainment and that boring road becomes something I look forward to. The times I elect no audio I use it to think on hard problems I am trying to solve or plan for These eliminate your counters of time consuming and boring. Regarding the inefficiency, you can do cardio that isn't running if you believe running is bad for you. I listen to the same thing during strength training

There are several studies that show adult neurogenesis from aerobic exercise, particularly running, in rats and mice. Example: Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained. https:/www.ncbi.nlm.nih.gov/pubmed/26844666 A review article here: https://www.researchgate.net/publication/5566493_Neurogenesis_and_Exercise_Past_and_Future_Directions https://www.researchgate.net/publication/5566493_Neurogenesi... There is at least one study that allows us to infer that the same effects may occur in humans (quoted below). Please let us know if there are more studies like this. It looks like a very practical approach to improve your cognition and prevent dementia with little risk. From: http://www.dana.org/Publications/Brainwork/Details.aspx?id=43678 http://www.dana.org/Publications/Brainwork/Details.aspx?id=4... "Columbia neuroscientist Scott Small and colleagues appear to have found a way around this problem. First, they put mice that had been running voluntarily for two weeks into a magnetic resonance imager to map exercise-induced changes in cerebral blood volume, a measure of increased blood vessel formation in the dentate gyrus. Then, by sacrificing the animals and counting new neurons, they were able to correlate the neuronal proliferation they observed with changes in blood volume. The researchers then conducted magnetic resonance tests on a small group of middle-aged people who had been exercising about an hour a day, four times a week, for three months. By charting exercise-induced changes in cerebral blood volume in the human hippocampal region and applying the same algorithms used in the mice, they were able to deduce that neurogenesis was also occurring in the humans. Changes in blood volume in the dentate gyrus, they concluded, provide a correlate of neurogenesis in humans." Anecdotal, yet may not be completely coincidental: Alan Turing was an avid marathon runner. This is not part of the argument--so please don't take it into account when responding. ;)

That first study does not support your claim. This is the main chart: https://i.imgur.com/pTFJkaJ.png https://i.imgur.com/pTFJkaJ.png. Note how it shows a significant response in Doublecortin+ cells only in the HRT group and not for the LRTs. These acronyms stand "for low (LRT) and high (HRT) response to aerobic exercise training". In particular, quoting from the article: Starting with a founder population of genetically heterogeneous rats (N/NIH stock), we applied two-way artificial selection based on the magnitude of change in running capacity after completing 8 weeks of standardized aerobic treadmill training. After 15 generations of selection, rats bred as HRT increased maximal treadmill running distance from 646 to 869 m (change, 223 ± 20 m), whereas rats bred as LRT decreased from 620 to 555 m (change, −65 ± 15 m) after completing the same absolute amount of training (Koch et al. 2013). This is a huge confounding variable. There is a very good chance these cells have an impact on these rats' ability to run long distances after training, so it's completely reasonable to expect that the cell growth would respond well to the very exercise the rats were selected for responding well to! It does not show that the same effect would happen in a normal rat (the LRT rats did not see a difference in this particular cell growth, but they were also nonrandom).

I thought multitasking had been shown not to exist. Since these people's minds don't wander I expect another study showing how Running is the Non-Creative's Sport.

>Could it not be that people who have the willpower to run regularly also have the willpower to stay focused? This is just an anecdote, of course, but I notice a major boost to my ability to concentrate, avoid distractions and think after a good aerobic exercise session. My efficiency goes from <1 hour of intellectual work done in a day to >4. The boost lasts about 2 days, after which the lethargy sets back in.

Well, the article states: > Of course, this type of study cannot prove that running actually caused the differences in the men’s thinking, only that runners had certain patterns of thought.

Maybe it's just that a prolongated uneasy physical activity trains people into not quitting and understand early sensations are only transient. Just a thought.
