World Championship in Light Athletics in Berlin

The World Championship in light athletics in Berlin has ended glamorously. Some spectators had a feeling of joy concerning high efficiency of athlets but, may be, also an idea of weakness, since many peoploe are interested in sports but don't use it seriously. Where are the limits of athletic exercises? The fabulous world record of Usain Bolt in short distance of one hundred meters in 9.58 sec could be lowered by a maximum of 0.3 sec, in the opinion of some experts. One is astonished about the top performances of some athlets from Kenia and Ethiopia in long distances. In this case scientists believe that the muscular system of runners from Kenia consume less oxygen than others. This means a greater stamina in relation to non-african competitors. It is unknown whether this economic consumption of oxygen can be obtained by training. If not these african magic runners will govern long distances in light athletics in the next future. This is a disadvantage of all others ... except those spectators who like effeciency in sports more than the colours of the national flag!
