To assess the structural features involved and influenced by performance in gymnastics, anthropometric factors such as weight, strength reported to active body mass, the hypertrophy and mobility level were analyzed together with functional elements such as the heart contraction rate during effort and globular constituents as hemoglobin(HGB) and hematocrit (HCT). The investigations were carried on a group of 10 elite male gymnasts belonging to the Male junior national gymnastics team that were examined over a period of 4 years, from 2007 to 2010. During the 2007-2009 interval the measurements were taken twice a year, in April and October, while in 2010 the data were collected in April. The outcomes were statistically interpreted using ANOVA: One-Way test and Pearson Correlation. The obtained values, although fall into normal, indicate a significant variance over the studied period. The gradual increase in weight (p = 0.001) was complementary to the continuous ascend of active body mass, reaching a peak in 2010 (p <0.01) (mean = 53.81 kg ± 3.77kg ). However, the strength level was highest in 2008 (p=0.0001), as opposed to mobility and hypertrophy that maintained constant. The average blood viscosity indicated by HCT values, having maximum values in 2009 (44.56%±3.48%)(p=0.04) has been positively correlated (corel. index. Pearson = 0.78) with the variations of the heart contraction rate during effort for the same year (p=0.04). The degree of cell oxygenation revealed by HGB has reached its peak in 2008(mean=16.14g/dL±0.69g/dL)(p<0.01), with a correlation of 0.8 with the strength level. In conclusion, the evolution of the anthropometric, functional and globular indicators has influences on the body’s constitution and on the sportive performances.
