The more you run, the denser your bones will be23 de Abril de 2016
Researchers have analyzed the effect of endurance running training on the stiffness index, a variable that is directly related to bone quality. The results confirm that the greater the race distance that is trained, the better; this can be used, therefore, to prevent the progressive decline in bone mineral density that occurs with age. In healthy individuals, bone quality – chiefly determined by bone mineral density – depends on factors such as sex, age, race and diet. It can be modified, however, by making life style changes -for instance by doing regular exercise.

High-performance swimsuit developed: 2.4% faster swimming with the dolphin kick20 de Novembro de 2015
Researchers have succeeded in developing a new high-performance swimsuit with a “kick assist system” that improves the power of the dolphin kick. High-speed swimsuits, which made their appearance at the 2008 Olympics in Beijing, were the driving force behind a barrage of new world records. However, the International Swimming Federation changed the rules significantly in 2010 due to a concern that swimming races were not being won by superior swimming techniques but by superior swimsuits, and the ruling body imposed strict regulations. These restrictions greatly narrowed the scope of swimsuit development and all but eliminated hope for improving swimsuit performance. To make a breakthrough under these conditions, the research group went back to the drawing board and put their heads together to figure out what exactly about a swimsuit allows a swimmer to go faster.

Exercise slows tumor growth, improves chemotherapy in mouse cancers22 de Março de 2015
One way many cancers grow resistant to treatment is by generating a web of blood vessels that are so jumbled they fail to provide adequate oxygen to the tumor. With oxygen starvation, the tumor gains a sort of cloaking device that protects it from the toxic effects of chemotherapy drugs and radiation, which are designed to seek out well-oxygenated tissue. Researchers have long tested various approaches to improving blood flow to the tumor in the hopes of restoring potency to treatments, however, to date, not much has shown promise.

In high-stakes soccer, goalkeepers exhibit `gambler´s fallacy´08 de Agosto de 2014
When goalkeepers are pitted against multiple kickers in tense penalty shootouts, their attempts to dive for the ball show a predictable pattern that kickers would do well to exploit. After kickers repeatedly kick in one direction, goalkeepers become increasingly likely to dive in the opposite direction, according to an analysis of all 361 kicks from the 37 penalty shootouts that occurred in World Cup and Union of European Football Associations Euro Cup matches over a 36-year period.Saiba mais
One shot, one chance: Can a soccer goalkeeper predict the kick strategy of a penalty taker?08 de Agosto de 2014
Since 1978, 23 nations have had their fate determined by a penalty shootout in the FIFA World Cup. When the penalty taker walks up to the penalty spot, they have the dreams of a nation on their shoulders; they have one shot to score the goal while the goalkeeper has one chance to predict which direction the penalty taker is going to kick the ball. As the tension mounts, all pressure falls on the penalty taker to score the goal, however why do few expectations fall on the goalkeeper to save the goal? Much research has been conducted designed to help penalty takers score, however a new study has identified the characteristics of kick strategies used by penalty takers which may improve a goalkeeper’s chance of making a save.Saiba mais
