In the past Great Prize of Germany, Italian pilot Jarno Trulli, who arrived third party, underwent fever and dehydration which influenced in its yield at the end of the race, besides the deterioration of the French tires Michelin.

In the past GP of Germany, Trulli could not attend the conference

How it is the behavior of the heart and the mind of a pilot of Formula 1 in a competition? The training must be optimal, since there are moments at which its heart arrives at the 200/210 pulsations per minute in the ambles.
From the arrival to boxes, the pulse and the arterial tension are already over the values of rest due to the adrenalin produced by stress. Very a well trained pilot has in rest between 40/60 beats per minute and at this moment already he reaches between 70/80.

In warm up (full tanks), its pulse rises up to 160/180 pulsations by min. Soon in briefing (meeting of pilots), their beats go up to around the 100 by min. When rising the single-seater to go to track one stays in 100. And it is acquiring greater concentration. When it sees that they lack 5 minutes psychic stress makes release more adrenalin him. This increases the sweating to him, begins the dehydration and the pulse rises to 120 beats/min. In the previous return they arrive at 140/min. And they lower to 130 when arriving at the released position from, perhaps the moment of greater risk in the race. With the sequence of the red lights the heart is accelerated thoroughly: 130, 140, 150, 160 Pul. /min. In the first curve, to the nervous tension the muscular work is added to him. Some arrive at 180/190 Pul. /min. in the breaking. They begin to feel the lateral and later accelerations. The pulse stays between 160/180/by min. If it rains, when the slow down the low pulse up to 140/159 min.

According to the temperature and ambient humidity they begin to appear the first symptoms of dehydration. The muscular metabolism and the impossibility to eliminate the sweating increase the temperature corporal to 38/39 degrees. The mouth is dry. The ears begin to hum. A V10 to maximum acceleration can arrive at the 140 decibeles. The corks in the external auditory conduit only absorb 30 dB. Therefore, dB must tolerate 110 (legally the authorized maximum is of 85 dB). This disturbs the transmissions of box via radio and the messages usually are misinterpreted.
The members inferiors begin to undergo fatigue. The dehydration and the muscular fatigue begin to bring problems. They appear cramps in the column, legs and forearms. They are cause of confusions, increase of the time of return, trompos and until abandonments.

The chassis of a F1 causes great vibrations to the conductors

The vision problems are added. The muscles of the eye also are gotten tired and the vision is disturbed, become cloudy, influenced by the vibrations transmitted by the tires and the jumps of track. Then the brain of the pilot is saturated of noise and fatigue. Sometimes it gets to lose the vision of the colors. The carbon fiber chassis is an excellent conductor and the resonances (between 70 and 90 Hertz) affect the retina and the larynx. The vibrations principles (150 Hertz) affect muscles and sinews and those of LF (5-10 Hertz) affect the bones, doing to vibrate them.
From to the end it continues increasing the dehydration there and the corporal temperature reaches 40 degrees. The glucose follows discharge. The adrenalin continues flowing. Their beats go between 160/180 by min. and they arrive at the 200 in the ambles.

The street guide of Montecar it is the circuit more plaintiff

Flag. When arriving at the closed park they begin to drink great amounts of liquid. Some take more than others in lowering of the car. Others need aid. And others cannot raise podio (the Seine in Imola '92), are desmayan (Piquet in Brazil '82) or do not arrive at the press conference, as it happened to him to Trulli.
For that reason, everything depends to take the maximum professionalism and seriousness on the part of all the equipment, and the people in charge of the maximum category so that these things do not return to happen.
