Anthropometric characteristics and performance related predictors of success in adolescent pole vaulters.

The purpose of this study was to determine the anthropometric characteristics of skilled adolescent pole vaulters and to examine the strength of anthropometric and physical performance variables in predicting vaulting performance (N = 87; age group range 13-18 years). The vaulting height of the subjects ranged from 1.98 to 4.72m (mean 3.58 +/- s.d. 0.536m). The vaulters were classified as ectomorphic mesomorphs with an average somatotype of 1.6-4.2-3.5 (s.d. +/- 0.38-0.94-1.00). One way analysis of variance showed that while measures of stature, physical performance and vault performance significantly increased (p < 0.05) across age groups, somatotype and sum of skinfolds remained stable. Stepwise regression analysis showed the best predictor of vaulting performance was hand grip height (R2 = 0.78, p < 0.05). Correlation analysis showed that grip height was strongly correlated to vault height (r = 0.88), age (r = 0.72), body mass (r = 0.71), standing long jump (r = 0.69), running speed (r = 0.69), biceps girth (r = 0.66), standing height (0.65), calf girth (0.61) and pull-ups (r = 0.44). It was concluded that the somatotype of skilled young pole vaulters is similar to that of junior Olympic and adult Olympic vaulters, and that this somatotype is a selective factor for this event as early as thirteen years of age. Proficiency in pole vaulting is best predicted by grip height, which is strongly correlated to stature and simple field measures of leg speed and power, and upper body muscular endurance. These findings may be applied to the selection and training of young pole vaulters.
