Genetic Differences

Yannis Pitsiladis at U. Glasgow has found that elite Ethiopian runners are significantly more likely to have a combination of four Y-chromosome gene variants than other Ethiopians, including those from Arsi (where Ethiopian distance runners originate). Pitsiladis points out that there is no one gene for distance running, though, and that the differences are not overwhelming. Pitsiladis and team hope to study Kenyan runners to see whether the same pattern is present. Original research in Human Genetics, reported in New Scientist 27 November 2004. (11/29)
