This article doesnt make mention of my workout where I lift something heavy 1 time.

As others said, your exercise does not burn enough calories to impact weight loss / gain.

I suspect your weight loss may be due to the exercise affecting your eating patterns (if you eat high calorie food before going to bed you will likely gain more weight than if you get same calories in a sweet drink right after a long ski race; not sure why).

Crazy, guaranteed.

"Myofibrillar hypertrophy" is the relevant search term. "Underground Secrets to Faster Running" by Barry Ross IIRC is a good read about high weight, low rep protocols. You can perform the same workout everyday of the week with long rests (5 min) between sets.

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.

So this is very interesting to me as a swimmer. I find that at the peak of my curve (where I train harder for the regional meet) I often get sick more often, and for far longer. In swimming, this is catastrophic to your performance for the meet, so we try at all costs to prevent illness, but it always happens to one or two of us. The question I pose, does this just apply to shot term exercise, or does intense training (5 hrs a day) for about a month have the same effect.

I have one rule: I only ever do sports if I have rested well the night before. It took me until I reached my 40s to realise that lack of sleep + heavy exercise = high chance of catching a cold.

Other sure ways how I can get sick: overdo sauna after exercising and, by far the worst, overdoing cold showers (Jim Hoff anyone? - I got seriously sick experimenting with that)

I guess the overall strength of my immune system is below average :-(

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..

Very low reps (1-4) at a high resistance (85-100% of a 1-rep max) is the standard powerlifter workout. But usually you'd do that for many sets. Lifting a 1RM for a single set seems either grossly inefficient (I have a similar max and it takes me 6 warmup sets just to get into the 405+ range), or he's risking injury by not warming up enough.

A 450lb deadlift is not crazy.

The standout quote for me: "[immune cells] moved elsewhere, migrating to the animals’ guts or lungs, portions of the body that might be expected to need extra immune help after hard exercise". Rapidly producing immune cells during exercise, then letting them (and more) die off would be a baffling response. But pumping them into the lungs (because you've been breathing hard through your mouth) and gut (for when you ma…

Also: "Statistically, their [marathon runners] odds of becoming sick were about the same as for anyone else in the race’s host city."

Yep - wasn't mentioned in the article, but I'd imagine the reason post-race marathoners are more likely to mistake coughs for colds is that marathons are also demanding. If your muscles ache and you're lethargic and coughing, that looks a lot like a cold.
