Ranger's training thread

[Byron Drachman]

No, as I said, my brother tracked as many physiological factors as he could, and he could not find any physiological source for the increased performance. So, his conclusion was that the effect is phychological[sic].

A more obvious conclusion is that your brother was unable to measure the physiological factors such as caffeine induced vasodilation that caused the increase in work.

It has been demonstrated scientifically (by my brother, no less) that caffeine enhances athletic performance by as much as 20%, especially when the effort exceeds a couple of hours.

The effect is not physiological, but psychological.

ranger's conclusion remains anecdotal at best.

The effect seems pretty big to me.

If the riders were going 30 mph, those he had the caffeine, too, went a mile and a half or so further in the 15min test.

And so forth.

As I remember, he tracked all sorts of things. I would surprised if he missed something essential.

My typo - 19.6 spi r20 is 1:36.25, or 6:25 pace. I've already done a 2k at 19.6 spi, rowing way better than perfectly. Ultra-mega-gynormously perfectly, in fact. I don't remember whether there was a screen shot or not. You can look for it if you have a spare week....

I did find this:

It's 6 x 500m r20 on 1', generally thought to be a 2k predictor. It's only 377w though, and 18.9 spi.

Wow, ranger calling for screenshots.

Yea, and posting them, too.

Nav--

Yea, as I said, the generalization that 2Kr20 is done at 2K + 10 doesn't hold at all for heavyweights, who have no size limitation.

I think it holds pretty well for lightweights, though, who have a size limit.

I suspect a similar correlation for heavyweights might have to be to a weight-adjusted ideal, e.g., 90 kgs.

Above that, the bigger you are, the better you could do for 2Kr20 relative to a free rate 2K.

Fraud. You edited the original post about 45 minutes ago to make it seem as though you said your generalization holds for LWs and not HWs. That's not what you posted originally.

Fraud. Fraud. Fraud.

Okay, show me the screenshot from this year of workout data. Not one huge pull force curve at the end of a 2:00 pace 300 meters. Show me something I missed and I'll apologize for calling you a fraud and liar.

The statement by ranger also was not talking about physiological response (as, I surmise, his brother was) but psychological.

No, as I said, my brother tracked as many physiological factors as he could, and he could not find any physiological source for the increased performance.

So, his conclusion was that the effect is phychological.

Caffeine dulls pain, perceived effort!

It makes us feel good, so we are willing to work harder.

Show us the exerpt from any citation that draws the "psycho" conclusion and shows a 20% better performance... As you said.
It remains clear that you do not acknowledge the necessary difference between work and performance.
We all agree that caffeine enhances one's resolve to work-out.... It is not a 20% boost of performance, though.


The will to work harder can also produce inferior performance if it is overdone.
Super edgy types can get nervous causing the individual to overestimate his prowess, go out fast, blow-up, and handle down. Ever notice that phenomenon?

Which bit of CES+CAF did you not understand?

I said '"up to."

The "performance" my brother looked at was a max 15min trial after two hours of UT2 (or low UT1) work.

In that context, the performance effect was indeed large--in the area of 20%.

This is just what has been reported by marathon runners for eons.

Caffeine helps runners get through the last 10K of a FM.

My brother was the principal investigator.

I didn't have to read the study.

I just talked to him about it when he was up in Door County.

The 20% improvement in performance was his finding.

His conclusion was that this effect is psychological, or put in other terms, "a stimulation of the central nervous system," etc.

Read your brother & associates' study: It speaks of "work" in joules... Not performance in pace for fixed time.
Please don't be obstructive just for a laugh.
