“…Up to date, several studies, mainly from the northern hemisphere, have addressed the performance needs of adolescent competitive tennis players, indicating that more information is needed about the role of maturity and growth in physical and athletic performance [1,9,10,14,17,[21][22][23][24]. However, in South America, such studies seem to be still incipient, focusing mainly on the study of anthropometric aspects [25,26] and the external load of the game [27], without considering its associations with levels of biological maturation.…”

The objective was to analyze anthropometric and physical performance variables as a function of chronological age and biological maturity in young Chilean tennis players. The study was observational, cross-sectional, with descriptive and analytical characteristics. Eighty-seven tennis players were evaluated (58 men 15.1 ± 0.8 years and 29 women, 15.3 ± 0.8 years). The measured anthropometric variables were a sprint test of 20m; a modified agility test; a sit-and-reach test and shoulder flexibility; manual grip strength; horizontal jump in feet; a medicine ball throw; a countermovement vertical jump; an abalakov vertical jump and a 20-m shuttle-run test. The growth velocity acceleration peak (APHV), skeletal muscle mass and fat mass were calculated, R2 and standard error of estimate (SEE) were examined. The results show that chronological age explained the anthropometric variables between 1 and 23% in men and 1 and 29% in women; by biological age, variables were explained between 3 and 53% in men and 2 and 42% in women. Of the physical performance variables, chronological age described between 2 and 24% of them in men and 1 and 29% in women; the same were explained by biological age between 1 and 19% in men and 1 and 26% in women. We conclude that anthropometric variables showed a better relationship with biological age, except for volume of fat tissue, while physical performance variables showed low association with both biological and chronological age.

“…(Matsuzaki, 2004) Tennis is a sport for all children, when regularly played it offers benefits for health associated with physical and mental development. Between 12-14 years, the children play single and double tennis on normal court, using a yellow ball and a regular racket (Schluga-Filho et al, 2016).…”

Twenty or thirty years ago the serve in a tennis game was used only to put the ball in play and not to gain points. Therefore, serve practicing was significantly reduced. Over time, there have been trainers and players who overseen solutions in order to increase the serve efficiency: using particular effects to misguide the opponent; growing the serve hitting power expecting to get direct points (aces); net attack in order to finalize the action by a volley or smash; expanding the serve practice. Nowadays, as technique, methodology and equipment have improved, the old role of the serve is surpassed, today being considered to be a winner includes incorporately the basic hits category. Improving the basic technical elements, serve included, is a key to the whole preparation process, and has great influence over the players' success rate in training and competitions. The methodology of improving basic elements must be part of the training, an essential condition of the game, which cannot be substituted by any other technique or tactics. In today's tennis, one can win direct points in a game if the serve is efficient. In children, in order to become effective, the serve must be improved step by step, using technical procedures.

Asymmetry in Body Composition Variables of Youth Athletes

Assessing bilateral differences in paired anthropometric features is an important methodological problem in sports anthropology. The present study included 128 adolescent female athletes (59 rhythmic gymnasts, 58 tennis players, and 11 swimmers). Body composition components were determined using multi-frequency bioelectrical impedance measurements (analyzer InBody 170). Asymmetry coefficients of muscle and fat mass accumulation in the upper (AA) and lower (AL) limbs were calculated using the Nacheva` equation (1986). The percentiles method was applied to distribute the bilaterally studied anthropometric features according to the mean values of the units of asymmetry (UA). Wilkoxon-test was used to assess the statistically significant differences in paired variables. Kruskal-Wallis test was applied to determine the differences in UA between three assessed athlete groups, depending on their age. The differences in body composition components between rhythmic gymnasts (RG), tennis players (TP), and swimmers (SW) were well expressed in all assessed age groups. The most considerable inter-group differences were observed in terms of the asymmetry coefficient in the lean body mass (LBM) with a right direction and body fat mass with a left direction for upper limb fat mass (%, kg), which have signed the highest values in the tennis players group, followed by the RG on the same age. Swimmers had significantly the lowest values of UA for all body segments. A close relation was found between asymmetry in body composition variables and the type of sports activity. Tennis was found as a sport with more pronounced inter-limbs asymmetry.
