25 miles an hour or more.But,instead of costing six million dollars,you can get a pair of "powerbocks"for
just a couple of hundred.
Mankind seems to have a strong desire to get off the ground.In the late 1890's stilt walking(踩高跷)
attracted Europe,with Sylvain Dornon walking from Paris to Moscow on stilts in 58 days.
The inventor of the Powerbock,German engineer Alexander Boeck,studied the movements of
kangaroos in order to develop his original design.And the Powerbock allows humans to extend their own
Achilles tendon(跟腱)to come close to the length and power of those in animals like kangaroos.As a
result,exercising using the stilts reduces wear and tear on feet and knees while still giving the body enough
exercise.
Powerbocking is considered as a form of exercise.You'll burn calories five times faster than jogging and
it employs 95% of the body's muscles.It's also an extraordinarily easy form of extreme sport to take up -it
only takes about 30 minutes to master the basics.
For a start,you'll instantly add 18 inches to your height.And then you'll be capable of the most
extraordinary skills of athleticism.Flipping(翻)backwards 20 times in 20 seconds to set a Guinness World
Record,for example,or leaping over cars.Acquiring them_is an awful lot of fun.It's not surprising that
Powerbocking has been turning up everywhere-on talent shows,commercials and even as part of the
closing ceremony at the 2008 Beijing Olympic Games.
But,he warned-if you're interested in taking up this sport,you need to know that no one can agree what
it should be called.The equipment is sometimes referred to as power stilts,jumping stilts,kangaroo boots
and many more.But there seems to be general agreement that the sport ought to be named
"Powerbocking"in honor of its inventor,Herr Boeck.
