An Athlete's Diet...




We've been launched into the days of continuous health warnings, from not drinking too much fruit juice to too much salt. The Commonwealth games start tomorrow - but what do athletes really eat?

Food means different things to different people. Although to athletes, it means fuel - essential for exceptional athletic performance. It's surprising the amount of variety and quantity of food they actually need. Even Wimbledon Champion, Andy Murray recently revealed that his girlfriend, Kim Sears, cooks him chicken, salmon or steak during the Wimbledon championships, so really, athletes aren't that restricted.

Anyone who followed Mo Farah's astonishing performance at London 2012 - probably didn't realize the secret of his success; consuming as many as 12,000 calories a day. Of course, most of us only need somewhere in the region of 1,600 to 3,000 calories. However, combined with training and the races themselves Mo Farah burned the 12,000 calories through blistering down the track at lightning pace.

It's not just swimmers for example that pound pancakes and pasta before competition, cyclists, marathon runners and rowers also have huge amounts of carbohydrates before competition - all in an effort to fuel their super intense continuous activity.

Although athletes follow their own specific routine, surprisingly wrestlers don't eat much before competition - they're at the completely opposite end of a pretty broad spectrum. So overall - what the athletes eat depends on their sport, even within sports, male an female athletes may eat very different amounts.

Does your brain shink with age?

It actually does, aged 80 your brain typically weighs 15% less than it did when you were 20. Neurones aren't normally replaced with minor damage also, your neurones get less effective with age too. This is one of the consequences of our extended lifespan, like arthritis and cancer. But studies have shown that if you remain physically active in your seventies then brain shrinkage slows down!
