The question about the specific structure of the body of professional runners were forced to think experts from all countries. In the global study, researchers have found a biological roots of the phenomenon of athletes from Jamaica.
Professional runners have more symmetrical knee joints than ordinary people. This allows faster acceleration and spend running less power. Scientists say than simetrichnee knee joints, the easier it is for the runner to break another world record. Especially symmetry helps runners for short distances without turns.
The study was conducted by anthropologist Robert Trivers, made in 2013, the assumption that the potential professional runners can be identified at the age of 8 years, and 22 years they will show the world's best results in running the 100 and 200 meters.
The next question facing scientists is the nature of the symmetry of the knee. In particular, interested professionals, whether this is due to the peculiarity of genes or not.
