Resumo

Use of smart devices to show the effect of modification rules and sports equipment on technical-tactical behavior in training stages, opens a new field of study to improve the teaching-learning processes. The objective of the study is to use the smart sensor “Zepp Tennis 2.2.1”, to know the impact of a modified competition (net height = 0.80m and field dimensions = 18.00x8.23m) in under-10 tennis players, according to the comprehensive approach criteria of optimization. The hits (n =7758) during 40 matches played by 20 players (average age = 9.46 ± 0.66 years) were the unit analysis. The study variables were as follows; a) number of strokes, b) percentage of hits impact in sweet spot racket; c) ball speed; and d) ball spin. The results show as follow: a) an increase in the use of flat strokes over topspin and slice; and b) scarce flat and slice play of the flat backhand appearance, nevertheless they show better values of linear and rotational speed than forehands. Decrease net height and court dimensions promote offensive behaviors in young tennis players. This offensive behavior coincides with the recommendations that encourage comprehensive approach to develop an optimal teaching-learning process.
