Physique characteristics of world-class African long distance runners

Abstract

It is becoming more important for sport scientists from Africa, who are world leaders in their own field, to do research on the sportsmen and women from Africa. Such research has an impact on scientific coaching, development and assistance for athletes from the African continent. Africa will also be able to develop and elevate itself on the terrain of sport science. The purposes of the study were to describe the physique characteristics (body composition and somatotypes) of world class African male and female long distance (LD) runners and to determine by means of a discriminant analysis which variables best discriminated among the male and female LD runners. Anthropometric data were collected on 21 male (mean age = 24.5 ± 5.52 years) and 19 female (mean age 22.1 ± 3.38 years) LD runners. The subjects were part of the athletes who were measured during the 6th All Africa Games held in Harare, Zimbabwe in 1995 (16 males and 15 females) and at the 8th All Africa Games held in Abuja, Nigeria in 2003 (5 males and 4 females). The anthropometric variables and techniques selected were those described in Norton and Olds (1996). Data analysis was performed using Statistica 6 (StatSoft, Inc., 1984-2003). A forward stepwise discriminant analysis was applied to determine which variables best discriminated among the male and female LD runners. The discriminatory power of the classification functions was established using the jack-knifed classification matrix. The male runners were significantly (p
