【推荐1】Everyone knows that running is a good way to stay in shape. The simplicity of running appeals to many people. You don’t need a lot of complicated or expensive equipment; you just need a good pair of running shoes. Well, that idea is changing.
This is not a surprise to the Tarahumara Indians, who live in northwest Mexico. The rough terrain (地势) in their area makes it easier to travel on foot than by horse or by car. Traditionally, the Tarahumara were hunters. They follow their prey over long distances, sometimes, for days, until the animals became exhausted.
But here is the amazing part: Tarahumara runners don’t wear running shoes. Tarahumara shoes are very simple. The sole (鞋底) is a piece of rubber held to the foot with homemade belt. These rubber soles protect against sharp objects, but they don’t provide any support or cushioning.
How is it possible that some of the best runners in the world don’t wear running shoes? Scientific studies are beginning to point to something the Tarahumara have known for centuries: Human beings are built for running barefoot. In a recent study, researchers used a video camera to examine how athletes run when they are barefoot.
A.The study revealed that barefoot runners land on the middle of their foot. |
B.Some researchers suggest that perhaps you do not need shoes at all. |
C.As a result, for the Tarahumara, running very long distances became part of daily life. |
D.Many of these shoes have higher heels that are equipped with special materials. |
E.As the force of impact drives the foot toward the ground, the arch flattens and expands. |
F.In response to this research, shoe companies started to reconsider the design of running shoes. |
The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person’s heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.
The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of “effective behavioral counseling for physical activity and diet. ”
The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups “showed significant improvements in fitness, physical activity, and diet,” with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.
Jakicic said, “the study’s findings are important because effective long-term treatments are needed to address America’s obesity. ” More information is needed, he added, to learn how to best use these devices to change “physical activity and diet behaviors” in adults who want to lose weight.
