F1 physical

I remember that few years ago David Coulthard fired his trainer because he could not keep up with David’s pace. When you look at the race, it seems unnaturally easy - they just cruise around, keep away (or at least should) from other cars and the gravel and all is fine.

And then you see Jarno Truli almost vomitting after the race, Fernando Alonso almost fainted after Hungary…there must be something more here…

Then you go and drive small carthing for 10 minutes and collect your internal organs for days. Man, how they drive for two hours…

And today, while I routinely checked F1-Racing-Live, there’s this:

  • All race drivers … are subjected to forces of up to 5G on track

  • Dehydration levels of just 2% have a negative effect on concentration levels, muscle contractile strength and endurance.

  • Losses of 5% or more can lead to up to a 30% drop off in physical performance.

  • Fluids are an integral part of any nutritional programme, because water comprises 92 percent of the blood in the body and 75 percent of the brain, as well as 75 percent of the muscle tissue.

  • Just a three percent loss of body fluid reduces muscle strength by 10 percent.

  • The drivers are working in a cockpit environment that can be over 50 degrees centigrade.

  • In an average race, a driver loses up to a litre of his body fluid. In Malaysia the heat and humidity can cause them to lose up to four litres

Nice, isn’t it?

In the middle of my current work overload, I completely neglected the comment moderation queue here. Thanks to my friend Lukija who asked me why I deleted his comment, I went to check and saw dozens of comments waiting. :(

Sorry people, I have approved all of them (and marked the other bunch as spam). I’ll try to catch-up and answer the questions asked. And re-check my comment settings…

Update: I had “email me whenever a comment is held for moderation” turned off, but also “before a comment appear Comment author must have a previously approved comment” turned on. Thus I did not received any notifications. One to learn.


New year, new rules, new attempt at making F1 more exciting. FIA is constantly tweaking rules, making sometimes drastic changes, just to stir things up. They used single qualification system with 4 hot laps for years, which was exciting enough and fun to watch, especially the last 10 minutes. Then they used two-Q system, where drivers can drive only one hot lap. Utter failure as F1 lost the qualification excitement when leaders change places at the top. Two consecutive Q sessions, with the order of driving in the second determined by the results in the first, made no difference and it looked as we had only one relevant Q-session with just one run per driver.

Now they tweaked more - the results from two sessions are accumulated and starting line-up is made out of those times. Pffeww…in essence, better than before. It can create far more exciting starts because of possible weather problems (like in Melbourne), although drivers would not like it. I couldn’t care less, as I watch the races for the good competition, not the commodity of the drivers.

The only thing they now need to do, to make it good, is to allow 3-4 runs per driver.

To be more precise, they should give the option to the teams to choose the number of runs between 1 and 4, maybe even 5. That would open up more strategy opportunities. Should we run two or four times? What about fuel-load? Gamble and run once with light fuel and then try to getaway at the start (building the time gap with better tire condition and less weight)? Or go four times? Or go heavy on fuel, one run and less pit stops? Account for differences in the track layouts and this could really add to the excitement board.

nice driving conditions

This year, the weather factor chimed in and really saved the day. Even though Renault showed excellent form in the pre-season (I reckon the best in the field), they were extremely lucky too. On the other hand, McLaren fans (yap, me) could only curse Miss Fortune.
