Fitness of an F1 driver
Imagine driving the fastest cars on earth, imagine the strain this puts on your body. Fitter than football players and leaner than athletes: racing car drivers possess the most finely tuned bodies on earth.
Medical studies consent. During a race a driver must remain calm, focused and in constant communication with the technical team whilst perfectly manoeuvring a highly complex vehicle around and unfamiliar track alongside competitors, travelling at speeds up to 300 kilometres/hour.
All this in an environment where one wrong move can cost lives calls for a sportsman at the very peak of physical and mental strenght. Fifteen years ago drivers achieved this by visiting the gym twice a week. These days they know better.
The heart
A human being has a resting heart rate of around 60 beats/minute, rising to around 150 during a run on the treadmill. David Coulthard (Red Bull Racing Team) has a resting heart rate of 40 beats/minute, rising to 198 beats/minute during a two hour race, a figure - approximately the same as that of a marathon runner crossing the finishing line - which initially stunned medical researchers.
Dr Riccardo Ceccarelli, from Italian sports medicine clinic 'Formula Medicine' and of the Panasonic Toyota Racing Team, explains why a high speed drive can be as challenging as a 26 mile run.
The neck
Ceccarelli "I know of no other sport that places such big demands on the neck muscles. A head and F1 helmet together weigh about 6kg. Add about 4G-Force as experienced when cornering in a Grand Prix, and the neck has to support 24kg."
Diet
Formula One drivers eat much like track and field athletes - carefully regulating their carbohydrate and protein intake. In the lead up to a big race they'll gorge on carbs - pasta and bread - for energy.
Immediately before the race and sometimes throughout, drivers absorb huge amounts of water. Failure to do so could bring on dehydration through sweating - the extreme heat found in a Formula One cockpit means drivers can sweat off up to 3 kg of their body weight during the course of a race.
