Wrestling Revs Up Immune System in Teens, Study Finds

Wrestling Revs Up Immune System in Teens, Study Finds reports on some good news for grapplers:

Cooper’s team evaluated the immune effects of exercise in 11 healthy 14- to 18-year-old boys. Blood samples were drawn before and after the boys participated in a 90-minute wrestling practice.

Wrestling exercise triggered a significant increase in levels of several types of white blood cells, Cooper and his colleagues report. So-called natural killer cells, which play a crucial role in the body’s first line of defense against outside invaders, surged the most, according to the report.

The researchers also found that the level of immune stimulation was related to exercise intensity. However, what role these exercise-related changes play in the overall development of the immune system is not yet understood.

Actually, the immune response appears in response to exercise, in general, in either adults or adolescents:

Although scientists have known that short bouts of exercise stimulate white blood cells in adults, this is the first study to show that exercise has the same effect in healthy adolescent boys.

Isegoria: Lower attendance is what we’re going for.
Bob Sykes: The problem facing all colleges and universities is that the number of white 18 year-olds, the primary consumers of college, is declining rapidly both relative to other races and absolutely. Many small liberal arts colleges are decidedly second rate academically, and so are the students they cater to. So, neither the loss of the schools nor the loss of the students is really a big deal. The health of the college system and the meaningfulness of the degrees awarded is actually better off...
Isegoria: Rising Sun came a decade later. I remember reading the novel right around when I read Jurassic Park. The Terminator, on the other hand, came out the same year as Runaways and was a much bigger deal.
Kentucky Headhunter: Huh, I remember Runaway being a fairly frequent Saturday afternoon movie option on cable. Not to the level of Rising Sun, but it was on at least once every three or four months. Now, unlike Rising Sun, I never actually left it on…
TRX: Crichton usually got his computer stuff correct, though. He picked up a degree in “computer graphics” while he was getting his M.D. at Harvard. When he decided he didn’t care for doctoring, he went to Hollywood and made more computer-ish movies than doctor-ish ones. I only discovered “Runaway” earlier this year; I thought I was familiar with all of Crichton’s movies, but apparently not. I don’t remember ever seeing any mention of it anywhere.
Isegoria: Crichton clearly had little interest in the details of weapons. In the movie, a household robot goes rogue and acquires a revolver — which makes a pump-action shotgun racking sound before each shot and leaves a ragged two-inch hole in the drywall. Sigh. So I’m not surprised he gets his warships mixed up.
Lucklucky: “battleship Sheffield” It was a mere destroyer not a battleship…
Jim: Equanimous Independence Day!
Buckethead: Adjacent to Atomic Rockets is ToughSF. Well researched and fascinating speculation on space. He posts only every so often, but he did do an interesting series on stealth – and piracy — in space.
Isegoria: Thanks for putting in the work, George. Grok also kept pointing to this blog. Apparently AI struggles with comments repeated across multiple pages.
George: Gemini claims (and I haven’t confirmed) that it’s: …a classic historical description written by the Scottish physician and traveler Dr. John Macculloch in his 1824 book, The Highlands and Western Isles of Scotland.He used this vivid phrase to describe the famous and treacherous pass of Glencroe… After searching all three volumes as PDFs, I’m pretty sure Gemini is hallucinating. And substantial time spent searching keeps leading me back to this blog. Cough up the...
Isegoria: I don’t think you’re alone in your struggle, Handle.
Grymalkin: Rudolf Jung (b.1882 – d.1945) was the first principal theoretician of National Socialism, a Sudeten-German trade-unionist and railway engineer who joined the Austro-Hungarian German Workers’ Party (later German National Socialist Workers’ Party, DNSAP) in 1909 and was heavily responsible for both building up the early successes of the movement and for establishing close links in the post-WWI era with emerging National Socialist parties in other German-speaking areas...
Handle: I liked Cal Newport’s World Without Email, but I have proven to be poor evangelist for its message. The default mode of email of permissionless universal access is bad (compare to needed to get affirmative consent for “direct liaison authority” like in the military) and everybody says they hate it but no one is willing to give up even a little bit of that capability, even though it’s essential to any system of attention preservation and disciplined communications. Sorry...
Bruce: Ludendorf’s WWI ‘War Communism’ and Marxist-Leninism rhyme.
Bob Sykes: There is no question that National Socialism is s form of socialism. Just ask G. B. Shaw or Time. One of the differences among socialisms is how they treat the national issue. Marxists are doctrine internationalists, and they used to maintain that the only distinguishing characteristic among people that really counts is economic class. That position seems to have been abandoned during WW I, because the proletariat turned out to be nationalists. Fascism and Naziism valorate the nation (or more...
Isegoria: It doesn’t appear to come from either Dracula or The Social Life of Small Urban Spaces.
Isegoria: I suppose I should have linked to my fourth Critical Chain post, which addresses multi-tasking.
Gaikokumaniakku: “The trail I walked lacked the geometric and artificial precision of the grand boulevards of the Städte I would later come to know so well. Here Nature did not bend to Man with such frequency or slavishness, but rather the two seemed to bend around one another at regular intervals, a grant of mutual dignity prevailing between the two. Here the paths wound around and through the hills, according to how the land pulled a man’s steps hither or thither. It was by this road, made by Man but...
Gaikokumaniakku: I’m a simple man. I see Goldratt, I feel compelled to wade into the comments section, even if I have little to add that the author has not already said. Overproductive workers who produce subassemblies are an example of physical constraints of part storage. Real-world factories don’t have infinite buffer space to store subassemblies. Overproduction is a problem for many reasons, but if we had some kind of Star-Trek-tier space warp for infinite storage, overproduction would be...
