ABSTRACT
The
present study evaluated age- and maturity-associated variation in body size,
proportions and estimated body composition and a new soccer-specific aerobic
fitness protocol labeled the Carminatti
Test. The contribution of chronological age, skeletal age (Fels method) and
body size to variance in peak velocity derived from the Carminatti Test was examined in three competitive age groups of Brazilian
male soccer players: 10-11 years (U-12, n=15), 12-13 years (U-14, n=54) and 14-15
years (U-16, n=23). Body size and soccer-specific aerobic fitness were measured.
Body composition was predicted from skinfolds. Analysis of variance and covariance (controlling for chronological
age) were used to compare soccer players by age group and by skeletal maturity
status within of each age group, respectively. Relative skeletal age (skeletal
age minus chronological age), body size, estimated fat-free mass and
performance on the Carminatti Test
increased significantly with age. Carminatti
Test performance did not differ among players of contrasting skeletal
maturity status in the three age groups. Results of multiple linear regressions
indicated fat mass (negative) and chronological age (positive) were significant
predictors of peak velocity derived from the Carminatti Test, whereas skeletal age was not a significant
predictor. In conclusion, the Carminatti Test appears to be a
potentially interesting field protocol to assess intermittent endurance running
capacity in youth soccer programs since it is independent of biological
maturity status.
Key-words:
Adolescence, field testing,
intermittent exercise, skeletal age, young athletes.
Um grande abraço, fiquem com Deus e até a próxima.
