My personal experience with long (100miles+) cross-country mtb riding (with lots of climbing) is that in fact, catching a cold after such a strenuous ride is way more common than the base rate. This is also the experience reported by most professional cyclists (check TdF reports). My under-researched model of how this happens, is that there is a lot of tear-and-wear in the muscles where the effort is happening, which…

runners and other endurance athletes I have met over the years, show noted skin aging after 40 years old..

So you do 1 Rep Max once a week. Not bad advice. How many warm up sets do you do?

It's actually very bad advice, do not do this. All of the literature will plainly tell you this is a bad idea.

Especially with deadlift, back injuries are no fun at all.

That may be more due to inadequate preventative sunscreen/protective clothing per outdoor time, every one who spends time outdoors without it shows signs of skin aging like the a/b test in one, truck drivers, with the side closest to window showing significantly more wear and tear versus the interior facing side. In addition to sunscreen, there are nowadays a lot of arm/leg covering just for SPF protection even in hotter temperatures - I always wear the arm protection/eyewear when outside.

Exercise pushes stuff around in your gut which is probably more directly related to the immune response than the possibility of eating raw meat.

Why would you go run (hunt) if there is still stuff (food) in your gut.

It generally takes 40+ hours from the time you eat to the time you poo. So, humans always have stuff in their gut. https://www.mayoclinic.org/digestive-system/expert-answers/f...

This article could not be more wrong, and anyone who has been a truly serious athlete will agree with me. There are perhaps a dozen times in my life when I was training with abnormally high intensity even for a very competitive endurance athlete and fell ill immediately afterward. These range from 2 hr brutal races to 3-4 days of 5-7 hrs daily intense training or race efforts. I very rarely catch a cold, but it's mor…

This is all anecdotal evidence that's pretty well countered by this statement: > Their first conclusion was that athletes are lousy at identifying whether and why they are sniffling. The original 1980s studies had relied on runners’ self-reports of illness. But newer experiments that actually tested saliva showed that less than a third of marathon runners who thought they had caught a cold actually had. Statistically…

The anecdotes of hundreds of national and world class athletes I have trained, raced, and interacted with over the years is worth more than any study you can paste here, my friend.

I suppose you are unlikely to see anyone here back me up since HackerNews isn't exactly an athletic demographic.

Fever, red eyes, overflowing mucus, extreme soreness and raw throat for days or over a week - are you trying to tell me that this isn't sick? Maybe that's your normal state, but I've seen hundreds of cases of amateur and professional athletes reduced to this shortly after performing national caliber efforts.

Best to hunt when you are loaded up on fuel. Don't want to be hunting when energy is low as you will most likely be less successful as your focus, patience, and response times will all be lower. Hunting isn't like going to the store, success isn't guaranteed.

I think the opposite. People that fast for a period (> 16 hours) report improved energy levels. This may be because after a while the body enters a ketogenic state where it burns body fat, which is a great source of energy and perfect for when on the hunt.

Depending on food type it can easily take over 2 days to digest food. https://www.mayoclinic.org/digestive-system/expert-answers/f...

You only present anecdata here, and you numerous times refer to "any serious athlete" or "any serious cyclist". But where is your scientific evidence supporting your claims? The article claims these claims are myths and you haven't contradicted that here.

As a machinist and building maintenance engineer, I can almost guarantee any ill feeling you're experiencing after a trip to your local gym is due to the air quality. Gyms are rarely purpose built facilities. Rather, theyre rented and renovated spaces. In turn, airflow in the structure is planned for light industrial or office space. Almost no thought goes into the fact that gyms are sometimes hundreds of occupants m…

You’re not even mentioning CO2 concentration. I work in a large, open office with seemingly sufficient airflow, but after buying a CO2 detector on a whim I’ve seen that it frequently reaches 1200ppm, and you actually can tell that you feel like crap when that happens.

I can’t imagine if the whole office was filled with people exercising.

This article doesnt make mention of my workout where I lift something heavy 1 time. I had the idea that I wanted to reduce time in the gym, so I used the potential energy equation PE= M g h I'm not getting any taller, so the only thing I could change was either the reps or mass of weight moved. I made it my goal to lift heavy weights so I'd only need to deadlift 1 time and be able to pig out. TBH, it works, I lose 1…

Found the fatty ;) Ok, seriously.... math: if you eat 3000 kcal per day and lose 1 lb per week, you're burning 3500 kcal per day. This is quite a lot. It's near impossible unless you work out a lot and are veeeery muscular... or are impossibly tall... or, well, fat. (Or a combination of those.) Take me for comparison: I am 187cm (6'1ish) tall and weigh 75kg (165 lbs), pretty much smack in the middle of the "normal we…

I'm the same height as you as recently dropped 5kg to 81kg due to fasting and cutting starch from my diet. Why wife started freaking out because I was looking so skinny (I'm not remotely fat normally either). I can easily burn 4000 kcal a day. All it takes is one hour on the bike. I burn ~3000 kcal on rest days. You have an endurance optimised build, I have a sprinters build. Everyone is different. Those numbers seem perfectly normal to me.
