What does it take to be G-fit?

The pilots of the Red Bull Air Race World Championship have to be strong mentally and physically. The biggest obstacle they have to overcome is G-force.

"It's the enemy in the aircraft," stated Michael Goulian. "It keeps you from being comfortable. It tries to pull you down into your seat, it tries to pull your hand off the throttle and you have to constantly fight against it," he said.

Goulian went on to explain that there are only two things a pilot can really do to combat the effects of G-force. "Weightlifting, which obviously makes you stronger, and building up your tolerance by flying," he said.

Unlike other sports training there is nothing you can do to build up a tolerance apart from fly (unless you happen to be NASA or own a G-force simulator). "Which is fine when you're doing it a lot," said Goulian. "But like any form of exercise, you lose your tolerances if you don't practise."

When preparing to race, Goulian tries to build up his G-fitness almost straight away. "I pull lots of G and wait until I start to feel my body shut down and my vision starts to close in. As soon as I feel that, I pull out of the turn. It tenses all the muscles in the back of my neck and it gives me an extra G of strength."

Matt Hall has a similar approach, which is something he learned in his military days. "It's called a G-warm," said Hall "I hold a five G-turn without tensing any of my body – when I start to grey out, I stop. Your blood pressure drops and when your body realises what's happening your heart rate increases and tries to get the pressure back up. For at least the next hour your body is highly tuned to the G-forces. It's your body using its natural mechanics to help you," he explained.

Hall also has a training regime to help him cope with the G. "Good core strength is important so lots of Pilates, but people don't realise that you need strong thigh and calf muscles to stop the blood rushing from your head into your feet," he said.

Here in the Rovinj track, the pilots have to cope with three high-G turns and each turn lasts about three seconds. Matt Hall explains how the pilots cope with the turn: "Before the pilot enters the turn, you'll see them take in a huge breath and hold it. They'll also tense their lower body and push their diaphragm down to keep the blood where it is."

Michael Goulian has the same technique. "Turning the turn I'll also breathe out quickly and back in sharply whilst tensing, it keeps the blood flowing and makes sure I'm fit enough to compete," he concluded.
