Triathletes Need to Consume Carbohydrates

This subject is topical at the moment with the Olympic Games in full swing. The triathlon is a popular sport where spectators admire the determination of athletes to push through the pain barrier and keep on going to the finish. Little work has been done on understanding how much damages is done to the body.

The half triathlon also called the intermediate or Standard distance run at the Olympics has become popular with many who just want to keep fit. Tests show significant reduction in knee extensor and flexure muscle strength at the end of an event. The ability to jump up off the ground is also reduced.

Considering dehydration and stores of carbohydrates which have been lost it is no surprise that weakness continues for some time after competing. However, dehydration was only minor in tested athletes. It seems the fat and muscle loss is the main cause. Participants in triathlons should concentrate on ingesting carbohydrates as well as fluid. Keeping blood glucose high has been found to maintain muscle force. Male athletes improved their race times by consuming carbohydrates. This was not the case for females. The reason for this is not clearly understood. Female metabolism must preserve carbohydrate stores even during strenuous exercise, but carbohydrate intake is recommended for women during an event.

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...

Study of Tooth Enamel Indicates Neanderthal Diet Was Carnivorous

 A new study on Neanderthal dietary practices has just been published in the journal PNAS by researchers from the French National Centre for Scientific Research (CNRS) and several German scientific institutions. They were able to determine that a Neanderthal who lived in a cave on the Iberian Peninsula during the Middle Paleolithic period (50,000 years ago) ate exclusively carnivorous food using a newly developed method for studying the chemical signatures of ancient tooth enamel. This isn't the first study to find this, either. Despite this, it is a one-of-a-kind and significant discovery because it was made through the development of a novel analytical method that could be used to learn more about the diet and way of life of Neanderthals who lived in other parts of Eurasia in the distant past.   To investigate the diet and eating habits of Neanderthals, numerous research projects have been initiated. However, they have resulted in contradictory outcomes. The CNRS researchers...
