Didn’t read study yet, but right off the bat a ‘submaximal treadmill test’ sounds pretty useless.
Also 40 pushups is probably a better predictor of obesity for the average American than strength. Obesity is a major risk factor for Cv disease, obviously.

At a BMI of 28.7 these guys are considered overweight, and not that far from moderately obese (BMI > 30). This seems to say something about the predictive accuracy of BMI.

You're right, just as Araujo' Stand sit and repeat test is a good indicator of mortality.
So let's say you took a sedentary flattish guy. Let's say he could only do 5 push ups on the first try. Have him practice for 3-4 minutes per day and try again in 3 weeks. I bet he could easily get to that magic #11 or more. I bet he would not have lost any weight (may actually gain some) and would not be any more fit, just able to do more push ups. And now he would be in a much lower risk category for heart disease? Most of heart disease has a genetic predisposition. What am I missing?
I think what you are missing is that the study participants only did the push-up test once, at a baseline health screening. So, they didn't repeat the test and 'train'. I don't know how much advanced notice of the test they had or whether any trained prior.
It's sort of a crap study in the sense there are so many confounders:
-the people doing more pushups were all younger (average age 35 vs 48 for less than 10 pushup group)
-people that are fit at baseline are more likely to be able to do more pushups (likely go to gym, aren't obese, etc)
-the people doing >40 pushups were significantly less obese than another groups (BMI of 27 vs 33 for less than 10 pushup group)
The only thing you can conclude from this 'study' is that younger, slimmer men in better health are generally able to do more pushups.
Wow, what a revelation! No one with any common sense would have predicted that!
Amazing that this stuff would get published.
Participants in the highest push-ups-completed group also had lower blood pressure and were likely to be non-smoking compared to the lowest group.
For a person who is 5'10", the BMI-associated weight would be 187lbs for the highest group vs 231lbs for the lowest group.
I don't think the push-up test was needed given all the other info.
from Table 1 in the Study (at
https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2724778
, on the right):
BMI = Body Mass Index, BP = blood pressure, SD = Standard Deviation
Lowest group of push-ups (0-10):
Age: 48.4
BMI: 33.1
blood pressure: 136.9/89.4
Smokers (Prev & Current): 54.7%
Highest group of push-ups (41+):
Age: 35.1
BMI: 26.8
blood pressure: 125.2/84
Smokers (Prev & Current): 30.9%
The point of the push up test was to be able to find a test for cardiovascular health without the time and expense associated with the treadmill stress test.
Wonder what it would be for pullups? I can do 40 strict at age 50.
Ok, let's consider the time and physical exertion that it takes to complete a high-rep push-up scheme.
A 'fitter' person will likely have superior biochemical thresholds and tolerances than a 'unfit' subject.
This test is a biochemical test (whether the researchers understand that or not). Replace the test with bodyweight squats for a made-up number, and you'll likely come to similar conclusions.
Yes but as other posters have indicated, the people able to do more pushups were younger, thinner, less likely to smoke, etc. basically they all already had known characteristics ‘protective’ from heart disease. These are easily and cheaply measured and so the push up test doesn’t add any other different information.
In summary, a useless study.
Men who can do 40 pushups are 13 years younger than those that do 10 pushups. So a 50 year old who is able to do 10 pushups could train pushups for a few weeks (or months if heavy) and reduce their age by 13.
You da man brah, the average fat American is lucky to do 3 pullups.
I can't do that many but I can aggressively thrust my pelvis while doing 10 in a row, so the affect
on those 'mirin is pretty much the same.
Pushups are simply an indicator of overall health. If someone can do less than 10 pushups, it tells a story about someone's lifestyle. It indicates a person is extremely inactive and likely obese.
The test obviously has its limitations like all tests. A really unhealthy person that practices pushups for a month and then passes the 10 mark obviously is not ar any lower risk of cardiovascular events than they were before they improved their capacity.
I think this is a helpful thing for a patient or physician to consider in the broader context of one's health.
You can design these little studies to say whatever you want.
I guarantee , that less than 5% of all males between the ages of 20 and 40 can do 40 push ups. (not the CrossFit type), the real pushups. No knees on the floor. No half up, real fast. full extension. Down to the human fist.

OK
Two cameras, one at chin-bar level.
I will be breaking the world record officially on March 30th. I will post video here or start a thread. Just 20 magical pullup workouts needed for prep. 1/2 way now.
That's impressive, brah! The real OCR question is: how many 10 second dead hang pull-ups can you do?!
