British Medical Journal did something quite awful today. It published seven articles around sports, exercising and nutrition, and how everything works in performance. Most of the articles scavenge and go through hundreds of researches and studies behind everything around sports nutrition and performance. Sports drinks being the main subject. Below is the link to all those articles brought to you by Yoni Freedhoff.

The most interesting was the article checking out different sport hydration and nutrition claims. These are the "myths" that are pretty much broken down. It gives a different look to evidence given before. These things might need way more research to be bulletproof:
- The colour of urine accurately reflects hydration
- You should drink before you feel thirsty
- Energy drinks with caffeine and other compounds improve sports performance
- Carbohydrate and protein combinations improve post-workout performance and recovery
- Branched chain amino acids improve performance or recovery after exercise
- Compression garments improve performance or enhance recovery

Discussion? Science is hard. There is either good science or bad science. Apparently, I've been reading more bad science. Altough there still are things that are not mythbusted but very true. Like the fact that correct nutrition pretty much eliminates the NEED for any post workout shakes.
Make sure to read the articles, they are interesting even though science might not interest you. Behold a quote:
"From our analysis of the current evidence, we conclude that over prolonged periods carbohydrate ingestion can improve exercise performance, but consuming large amounts is not a good strategy particularly at low and moderate exercise intensities and in exercise lasting less than 90 minutes. There was no substantial evidence to suggest that liquid is any better than solid carbohydrate intake and there were no studies in children. Given the high sugar content and the propensity to dental erosions children should be discouraged from using sports drinks."
