This study aims to raise an intermediate proposal for basketball in the children’s category that will make the transition from mini-basketball to adult basketball progressive. To this end, we have studied the impacts on the free throw shooting technical pattern of five regulatory adaptations resulting from the combination of three types of ball -numbers 5, 6 and 7- and two basket heights -at 3.05 m. and at 2.80 m. from the ground-. Through statistical analysis and the detection of temporary patterns, erroneous technical aspects have been established in certain modalities under study, which enables us to raise intermediate proposals for adaptation of basketball for 11-12 year olds.

Padel is a very popular sport in countries like Spain, Argentina and Brazil, but there is a lack of scientific papers analyzing the harmfulness of their practice. Padel movements could potentially damage the foot and ankle joint. Therefore, the objective of this study was the characterization of the foot role during the execution of the most representative padel movements by techniques of pressurometry and video. The study was divided in two parts: pressurometric analysis of two movements (head-on displacement and split-step), and video recording of the foot during two games. The main conclusions of the study are the importance of forefoot zone in the padel movements, the importance of a specific shoe design for padel practice, and the importance of neuromuscular and proprioceptive training of the ankle and plantar flexors.

The body mass index (BMI) is one of the mostly used criteria to define obesity in children. However, it determines the nutritional status, while the total body fat demarcates body composition. Therefore, the objective of the study was to determine the relationship between body mass index and body fat percentage in 505 students (242 female and 263 male) of Barinas state Bolivarian High School, aged between 10 and 20 years. The research was part of the quantitative approach, a kind of field research, based on a non-experimental, correlational descriptive level and cross section. Data analysis was performed using SPSS statistical software version 17.0. The results show a high correlation between BMI and body fat percentage (r: 0,75 ** for girls and r: 0,77 ** for boys, p <0,01). Also showed high and significant correlations in different age groups for both sexes. For the male G1: r: 0,81, p <0.01, G2: r: 0,82 **, p <0.01 and G3: r: 0,66 **, p <0.01. In the case of women the relationship was G1: r: 0,72 **; G2: r: 0,83 ** and G3: r: 0,81 **, p <0.01. It thus concludes that there is high positive correlation between BMI and body fat percentage in the educational institution mentioned therefore considered the use of BMI as a tool applicable for estimating nutritional status.

The work starts with a description of a present outlook of the Physical Education and its difficulties to include sensitive learning based on motive behaviour,as it has been historically proclaimed by some great people. The goal is to place the person as the central object of the learning action,considering the subject as a whole, immersed in his reality. Introducing the method Movitransfer from its essence and which was created after a thorough research made by the Argentinian Physical Education teacher Alberto Masciano,at the Olimpia Gymnasium in Chivilcoy, Argentina. In it, uniqueness, meaningfulness, motive interaction, conscious perception, motive tasks designed in stages, and the gymnasium as a motive laboratory are the key concepts. Eventually, the idea is reinforced with very interesting evidence given by the real protagonists.
