'Build up slowly' for barefoot runs 12 September 2013Last updated at 17:32 GMT By Suzi Gage Reporter, BBC News, Newcastle Bare foot running - good or bad? Careful readjustment is vital for anyone taking up barefoot running, sports scientists have warned. An overview of research was presented at the British Science Festival in Newcastle. Claims that running without footwear might improve technique and result in fewer injuries have led to many runners taking it up. Dr Mick Wilkinson, from Northumbria University, also claimed that it was best to start off on hard surfaces.
The Mind-Blowing Way These Tribesmen and Wild Birds Work Together Calling to each other with chirps and yelps, a species of bird and a tribe of humans in southeast Africa forage for honey in unison. The birds lead the way to hidden beehives, which are camouflaged among high tree branches. The tribesmen crack open the hives and share the sweet spoils of victory with their bird friends. Origami Footwear: Lightweight Lace-Free Shoes Wrap & Fit Any Feet A Japanese designer and Italian shoemaker have taken a fresh approach to athletic footwear, adapting the minimalist art of cloth wrapping to form the basis of a flexible shoe that fits any foot shape. Masaya Hashimoto worked with Vibram, the makers of foot-shaped FiveFingers shoes (with articulated toes), to create the Furoshiki series of shoes with wrapping soles that fold around feet without needing laces (a simple hook and and loop system). A specially-engineered gripping system keeps the shoes in place and make it possible for the shoe to perform like ordinary footwear but with less weight and material. The system has a number of advantages, including more flexible sizing than traditional shoes, easier packing for travel and the ability to skip socks comfortably. From Vibram: “The concept for this type of footwear was derived from the Japanese custom of packaging items by wrapping them in cloth fabric.
Carlos '97 free kick no fluke, say French physicists Roberto Carlos' free kick goal against France in 1997's Tournoi de France is thought by many to have been the most skilful free kick goal -- from 35m with a powerful curling banana trajectory -- ever scored; but by others to have been an incredible fluke. Taken in 1997, a year before the French won the World Cup, Brazilian Carlos's goal held France to a frustrating draw but, now, a group of French physicists -- perhaps with a nostalgic eye to a happier time for French football -- have computed the trajectory and shown that Carlos' goal was no fluke. The research published Sept. 2, 2010 in New Journal of Physics, explains why French goalkeeper Fabien Barthez made no move for the ball (but why a ball-boy ten metres from the goal did duck to safety) as the ball made a last moment sweep left and landed in the back of the net. Carlos' free kick can be seen on YouTube here:
That was really close About What's New Tools Privacy How Exercise Affects Immunity Jim Brown March 11, 2013 Exercise as it relates to immunity is a mixed message. Regular, moderate-intensity physical activity has been shown to help protect people against some diseases, particularly those that involve the upper respiratory track (like colds). However, too much exercise can have the opposite effect and reduce immunity. The keys are (1) knowing how much exercise is enough, (2) when exercise is appropriate and when it's not, and (3) which types of exercise are appropriate for your particular situation.
BBC Science - Everest: how science conquered the world's highest mountain 28 May 2013Last updated at 01:57 By Christopher Brooks BBC Scotland Mount Everest was once the domain of elite mountaineers. In the week of the 60th anniversary of the first ascent, the world's highest peak was climbed by 80 year old Yuichiro Miura of Japan.
