There is virtue in working standing up. It sounds like a fashion. But it does have a basis in science.
That, by itself, may not be surprising. Health ministries ask people for decades to do more exercise. What is surprising is that long periods of inactivity are bad regardless of how much time you also spend on officially approved high-impact stuff like pounding treadmills(跑步机) in the gym. What you need instead, the latest research suggests, is constant low-level activity. This can be so low-level that you might not think of it as activity at all. Even just standing up counts, for it invokes muscles that sitting does not.
Researchers in this field trace the history of the idea that standing up is good for you back to 1953, when a study published in The Lancet found that bus conductors, who spent their days standing, had a risk of heart attack half that of bus drivers, who spent their shifts on their backsides. But as the health benefits of exercise and vigorous(强度大的) physical activity began to become clear in the 1970s, says David Dunstan, a researcher at the Baker IDI Heart & Diabetes Institute in Melbourne, Australia, interest in low-intensity activity — like walking and standing — became weaker.
Over the past few years, however, interest has been excited again. A series of studies, none big enough to provide convincing evidence, but all pointing in the same direction, persuaded Emma Wilmot of the University of Leicester, in Britain, to carry out a meta-analysis. This is a technique that combines diverse studies in a statistically meaningful way. Dr Wilmot combined 18 of them, covering almost 800,000 people and concluded that those individuals who are the least active in their normal daily lives are twice as likely to develop diabetes(糖尿病) as those who are the most active. She also found that the immobile are twice as likely to die from a heart attack and two-and-a-half times as likely to suffer cardiovascular disease as the most mobile. Crucially, all this seemed to be independent of the amount of vigorous, gym-style exercise that volunteers did.
Welcome to one of the largest collections of footwear（鞋类）in the world that will make you green with envy. Here at the Footwear Museum you can see exhibits（展品）from all over the world. You can find out about shoes worn by everyone from the Ancient Egyptians to pop stars.
Room 1 The celebrity（名人）footwear section is probably the most popular in the entire museum. Stared in the 1950s there is a wide variety of shoes and boots belonging to everyone from queens and presidents to pop stars and actors! Most visitors find the celebrities' choice of footwear extremely interesting. | Room 2 Most of our visitors are amazed —and shocked— by the collection of “special purpose”shoes on exhibition here at the Museum of Footwear. For example, there are Chinese shoes made of silk, that were worn by women to tie their feet firmly to prevent them from growing too much! |
Room 3 As well as shoes and boots the museum also exhibits shoe-shaped objects. The variety is unbelievable. For example, there is a metal lamp that resembles a pair of shoes, and Greek wine bottles that like legs! | The footwear Library People come from all over the world to study in our excellent footwear library. Designers and researchers come here to look up information on anything and everything related to the subject of footwear. |
