Observing the drivers of F 1, we can find that they all have thin necks, which look almost as wide as their heads. This is because when driving F 1 racing car, the head wearing a helmet is exposed outside the cockpit, and it must bear 5 g of lateral centrifugal force when cornering, and the forward deceleration force is also above 5 g when braking. Under such a high centrifugal force, the weight of the head and helmet will be five times that of the original, about 25 kilograms, so a particularly strong neck is needed to resist centrifugal force and maintain the position of the head.
Secondly, their arms and wrists are extremely muscular. Generally speaking, it takes about 30 kilograms to operate the steering wheel of F 1, but it takes more power to turn the steering wheel at high speed, and it takes more powerful arms to keep the car on the route that the driver wants when turning. Strong arms and wrists are necessary in the 300-kilometer race.
Racing is a sitting upper-body sport, and most drivers in F 1 will consume oxygen in the upper body during the race. Therefore, some people jokingly compare the F 1 driver to a marathon runner in a wheelchair, because the oxygen consumption of the F 1 driver during the competition is equivalent to that of a marathon runner.
In addition, when cornering, strong lateral centrifugal force will make the blood in the body flow to one side, but at this time, the driver still needs to keep calm thinking and judgment ability. The racing driver's heartbeat will be as high as 190 beats per minute at the start of the car and around 160 beats during the race, so the driver's cardiopulmonary function must be extremely strong.
The heat resistance of the car body is also very important for F 1 drive. In cool European competitions, the temperature in the cockpit can be as high as 50-60 degrees Celsius. In Malaysia's high-temperature Sepang circuit, the cabin temperature will even exceed 80 degrees Celsius. Although drivers can constantly replenish water, after nearly 2 hours of competition, the total body fat consumption and dehydration will exceed 4 kg. If it is an ordinary person, it will cause shock under such a large amount of dehydration, but the driver of F 1 can still talk and laugh after getting off the bus.
