Middle-Age Men Who Can Do 40+ Push-Ups Have Lower Heart Disease Risk, Study Finds (cbslocal.com)

A new study finds that active middle aged men who can do more than 40 push-ups at a time have a significantly lower risk of heart disease. From a report: Researchers at the Harvard T.H. Chan School of Public Health followed more than 1,100 middle-aged male firefighters over a decade. They looked at two specific measures: how many push-ups they could do and their exercise tolerance on a treadmill. They found that men who could do more than 40 push-ups had a 96-percent lower risk of heart disease than those who could do no more than 10 and their ability to do push-ups was a better predictor of cardiovascular disease than their stamina on a treadmill test.

      The important part of the statement is that the number of push-ups that you can do may be a better determinant of cardiac health than an Exercise Treadmill Test (ETT). An ETT is currently used by hospitals to determine cardiac health. If a physician can get equal or better information by having a patient do push-ups in the local office, they may be able to skip the more expensive ETT.

      It is also something that a patient can do at home to determine heart health. If you're over 40 and can only do 25 push-ups, it may be time to ask your physician to pay special attention to your cardiac health.

Yet there is no evidence that years of endurance exercise will shorten your life." He wants to reconcile such findings.

As such, it warrants a controlled study specifically designed to test only that hypothesis. Otherwise you run the risk of odd results showing up that aren't really being studied.

      On the other hand, doing a lot of push-ups requires significant upper body strength. Building and maintaining strength is hard work; it reflects a dedicated fitness program or regular physical labor.

      If the analysis could control for overall physical activity (duration+intensity), I would expect that to be the lead indicator rather than push-up count.

      Any activity that you sustain for more than about a minute is almost certainly not mostly anaerobic. High school biology texts often talk about metabolism "switching" from aerobic to anaerobic, but that's not really what happens. When you begin to exercise your muscle metabolism is almost purely anaerobic, as aerobic respiration takes a while to ramp up. That happens over the first two minutes or so. If the energy demands are below your anaerobic threshold, aerobic respiration then provides all the required ATP. If not, anaerobic metabolism makes up the *shortfall*.

      Aerobic respiration is limited by how fast you can deliver oxygen and substrate. Sustained anaerobic respiration is also strongly influenced by muscle perfusion for a variety of reasons, one of which is maintaining a workable ionic environment around and within the muscle cells.

Male firefighters aged 18 years or older who had no job restrictions at the time of their initial examination were included in the study.

    For push-ups, the firefighter was instructed to begin push-ups in time with a metronome set at 80 beats per minute. Clinic staff counted the number of push-ups completed until the participant reached 80, missed 3 or more beats of the metronome, or stopped owing to exhaustion or other symptoms (dizziness, lightheadedness, chest pain, or shortness of breath).

    The current study has several limitations. First, the study assessed the association between push-ups and CVD events.

Clinic staff counted the number of push-ups completed until the participant reached 80, missed 3 or more beats of the metronome, or stopped owing to exhaustion or other symptoms (dizziness, lightheadedness, chest pain, or shortness of breath).

    That's much too fast to do a proper non-ballistic pushup. There's also no discussion of range-of-motion.

      Unless you're very old or female, you should be able to do at least a couple of proper pushups. Unless of course you have some physical disability (obesity would count as a disability here)

      Assuming that's the case (your disability is obesity rather than something irreversable like paraplegia), you should really make an effort to improve your fitness to the point where you can at least do a couple. Start by doing some knee pushups every day. If you can't even do a knee pushup, try inclined ones. Gradually increase the reps until some day you can do a proper pushup. Your body will thank you.

    It is nice to see more confirmation in this direction. Almost all research in the past decades was focussed on the health benefits of endurance training, however strength seems to be a better indicator for health than endurance, e.g. as noted in this longterm study, even when equating for lifestyle choices like smoking (so it's not that stronger people just make better decisions).

    Grip strength seems also to be a good (and easy to measure) indicator. Also the stand-sit test which has become common practice in geriatry is practically a measure of strength.

    Why muscle and strength (of course one has to exclude enhanced athletes with supraphysiological amounts of muscle) is so healthy is still not totally clear, but there are already two factors standing out, which cannot be replicated by endurance type of training: The first benefit is better mobility and protection against injury, in particular in high age. Second, when you are hit with a wasting disease, or just stop eating like you used to and get into a protein deficit, your body can take those aminos from your muscle instead from your precious vital organs. In particular atrophy in the heart is very hard to reverse (a struggle many recovered anorexics have).

    Are we suggesting that people should say screw all to all other exercise and focus on 40 push ups?

    Iâ(TM)m over 40 and can do 20-25 proper push 3 count push ups. I will likely have problems in time. I use a rowing machine and have good circulation. I simply have never been able to develop the muscles required to handle 40 push ups.

    Actually, they say that they corrected for age and BMI, though they don't specify how.

    Exactly. They don't say how. This is the single most important part of the analysis -- the results mean nothing whatsoever without this "correction"-- and they dismiss it in one sentence.

    The graph they show-- survival versus years since start of the study-- is entirely useless. The dark grey curve needs to be shifted 13 years to the right to make these two curves consistent with each other. Since the graph only covers 10 years, this means that the curve needs to be shifted off the chart.

    What worries me the most (from a scientific point of view) is that they say that they only found a statistically significant effect between the 0-10 and the 21-30 pushups groups.

    This is correct. Once you look at the adjusted results (adjusted how?), you see that the confidence intervals no longer are distinct.

    I assume that means they used pairwise tests.

    That phrase you use-- "I assume"-- should never be used when interpreting a scientific paper.

    Far too often, the phrase hides "we didn't take the trouble to do it right, so we're shuffling the details where nobody will notice.

    Cardiovascular events are highly nonlinear with age. In fact, the expected number of cardiovascular events for the lower age groups is pretty close to zero. Any correction is going to amplify noise.

    They report the 95% confidence intervals, which then means that they didn't correct for multiple comparisons. This is an instance of p-hacking, if I ever saw one.

    No. It shows that ability to do push-ups is a good predictor of... age.

    That's what the article says, and the table you linked to does nothing to contradict it. Age is the easiest thing in the world to control for.

    Age is very hard to correct for in cardiovascular studies, and when you "correct" two groups that are pretty much non overlapping (the difference in means is larger than the standard deviations), it is effectively impossible. Cardiovascular events are very highly nonlinear with age, and the age they happen to use here is one where the many-push-ups groups is of an age where cardiovascular events are very very rare. Most of the events you're going to find are going to be with the population that is a standard deviation older than the mean.

    And in any case, since this "adjustment" of the data is critical to the results they give, they should have documented how they did that adjustment.

      Age correlates with cardiovascular outcome, but that's not news.

      Here's a graph of chance of heart attack versus age. https://heart.bmj.com/content/...
      The 41-pushup group averages 35 years old, which puts them on the very left edge of this graph, which is to all practical purposes "negligible chance of heart attack". Telling me that they have few heart attacks isn't news. Of course they don't, at 35 years, heart attacks are very uncommon.

      The less-than-10 pushup group averages 48.4 years old, where the curve is rising... but the standard deviation of 10 means that a significant number of them are over 58 years old, where the curve is definitely non-negligible indeed.

      So, the data tells me that the 58 year olds have more heart attacks than the 35 year olds. That's not news.

      I don't understand your question. I didn't say the effect was "negligible", I said that the data did not support the conclusion. The cohorts did not overlap; you can't compare them, and since you can't compare them you can't say whether there's an effect or not.
