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.

Summer of Science Day 4 - One Giant Leap for Selfies?

21st July 1969 - The Summer of '69!

Today the attention lies predominantly on the 45th anniversary of the moon landing; where 99% * of the world's TV screens were tuned into NASA TV. Neil Armstrong stepped onto the moon's surface at 0256 GMT with the eyes of the world focused on him. Only 14 minutes later Buzz Aldrin stepped out onto the lunar surface, jumping across the moon's surface collecting rock samples taking advantage of the stunning view from here on Earth. 

On the other hand, Buxzz Aldrin and Neil Armstrong aren't just famous for their landing on the moon. Buzz Aldrin has laid claim to the first "space selfie" in 1966 - is this where the trend comes from?

The Great British Weather - Thunderstorms!

It's fair to say Britain isn't best known for its excellent weather and roaring sunshine. Over the past week or so, we haven't been far off the roaring sunshine - it's just it's quickly followed with rather dramatic thunderstorms! Thunder causes lightning - this is essentially a stream of electrons flowing either between clouds or from a cloud to the ground. The air surrounding this electron stream is heated to around 50,000 degrees Farhenheit. It's a staggering three times hotter than the surface of the sun. When the lightning is within our sight, we see it first as the speed of sound in air is considerably slower that that of the electron flow. The light from the flash reaches us in a fraction of a second, whereas the sound lags along like a snail following an interplanetary rocket.

Summer of Science

Over my summer holidays, I'll be posting an article every day (starting from  tomorrow)  on here about all things science - so keep an eye on my blog!

Also take a look at my eBook that's currently on the kindle store- Science Bites : A Short Tour of the Universe. It's a charity eBook, so all the profits (around 50p per eBook sold) go to Keech Hospice. (http://www.amazon.co.uk/Science-Bites-Short-Tour-Universe-ebook/dp/B00LHOXRO4) It's sold around 140 copies, I now just need feedback and more sales! :)

Here, I'll be adding links to all of the posts, although please  be aware these might be a couple of days behind! :)

Who was Gustav Kirchoff?

(1824-1887)

He came from a very intellectual Prussian family and he studied Maths and Physics at the University of Kongsberg. Here collaborated with Robert
Bunsen in 1854 (who invented the Bunsen Burner) for research into spectroscopic studies, which is research into a specific area in Quantum mechanics. Kirchoff made a lot of contributions to the study of optics (light) and he was even one of the first to use the term "black body radiation. 'Black Body Radiation' later evolved into the term we now use "Cosmic Microwave Background Radiation" , scientists believe this is radiation left over from the Big Bang!

Does the Sun's cycle influence our weather?

The Sun's magnetic field constantly changes - the Sun's polarity reverses every 11 years. This activity changes the number of sunspots on the Sun's surface - this then peaks at the 'solar maximum'. The Sun's activity cools areas on the Sun meaning they appear darker. The solar cycle can also cause small changes in the Sun's heat and light output. Some studies have shown some link between few sunspots and cold winters in Europe. Although it's unclear the Sun's cycle could influence our weather.

Europe launches a flagship space project

A Soyuz rocket has been launched from France carrying the first satellite for Europe's multi - billion euro project to map the Earth's surface using radar.

The satellite, named Sentinel- 1a will be followed by a fleet of other satellites over the next five years also called sentinels.
