Formula 1 racing is a fascinating world that pushes boundaries beyond our imaginations. The excitement, the roar of the engines, and the adrenaline rush are just the surface-level appeals.

Since taking the plunge into the world of GT racing at the end of 2019, I’ve navigated the intensity of six endurance races and felt the swift pace of over 20 sprint races. As your orthopedic surgeon, this journey has provided me a firsthand insight into the physiological nuances of motorsport

Most people see car racing as a test of speed and skill. Yet, beneath the helmet and fireproof suit, there’s an intense physiological drama unfolding. Let’s journey through this thrilling yet demanding world together.

The Heartbeat’s Wild Ride

Heart rates in racing drivers can soar to levels seen in marathon runners. A Formula One driver can experience average heart rates of around 170 bpm, peaking at 200 bpm[^1^]. This isn’t just from the physical exertion, but also the mental strain of focusing for long periods at such high speeds.

Staying Cool in the Heat

Imagine being wrapped in thick clothing and seated in a high-temperature environment (up to 50°C or 122°F) for hours[^2^]. The body sweats profusely, losing vital fluids and salts. It’s not unusual for drivers to lose up to 3 kg of body weight in sweat during a race[^3^].

G-Forces: The Invisible Wrestler

The rapid acceleration, braking, and cornering in races subjects drivers to intense G-forces. In Formula One, drivers experience forces up to 6G in braking zones and around corners[^4^]. That’s like having a 600-pound weight pushing on you!

During the 2019 Copa Notiauto 24 Hour endurance race at Autódromo Hermanos Rodríguez, Dr. Saldanha transitions out as the next driver prepares to take over, amidst the orchestrated chaos of the pit stop.

Breathing Under Pressure

During these high G-force moments, breathing can become challenging. The force makes it harder to inhale, as the lungs and diaphragm are pushed upwards. Drivers, therefore, have to learn to breathe using their stomach muscles, a technique I had to master during my GT racing stints.

Mental Gymnastics

Racing demands intense concentration. This is very similar to the concentration in the operating room. One lapse can result in catastrophe. The FIA, the governing body of motorsport worldwide, recognizes the importance of mental fitness and often has programs to assist drivers in achieving peak mental performance[^5^].

The sport might look simple to the untrained eye, but it demands as much, if not more, than many other high-intensity sports. It’s a dance of endurance, strength, and focus, all while traveling at speeds that make everything a blur.

Next time you’re watching a race, or even driving your own car, think of the incredible stresses the human body endures in the quest for speed. It’s a testament to human resilience, determination, and our never-ending quest for adrenaline.

Stay safe, and remember, whether on the track or on the road, respect the machine and understand the physiology behind the thrill. I’ll see you at the finish line!
