Fit to Drive: Getting in Shape


Everybody knows that lazy people always prefer to drive to their local shops rather than walk, but driving a racing car is certainly something only the fittest athletes can do. Formula One drivers may not look as big and brawny as some other athletes, but the stresses and strains of performing at 200 mph on a baking hot summer’s day means that normal people would collapse from exhaustion after just a few laps.
The huge g-forces, where bodyweight is increased to three or four times normal, that drivers experience when they brake or go through high-speed corners can literally knock the air out of their lungs. And although drivers have to be quite light (being large and heavy makes them slow), they have to make sure that the top half of their body is strong enough for the forces needed to drive the car. At more than 150 mph, it takes an effort of 20 kg to turn the steering wheel – certainly more than the road car sitting outside the front of your house.
Tests carried out on Formula One drivers have shown that their heart rate can soar to 185 beats per minute at the most stressful part of races. This is the same kind of rate that fighter pilots experience in the heat of combat.
