- Analysis of anthropometric and physical performance variables in U-17 soccer playersPublication . Honório, Samuel; Batista, Marco; Serrano, João; Vandoni, Matteo; Rebelo, Miguel; Vieira, Fernando; Lopes, André; Santos, JorgeSoccer is considered a multifaceted collective sport, and to reach an elevated level, players must have moderate to high power, good agility, joint flexibility and muscle development. Also, players must be able to generate high torques during fast movements, which implies the development of different capacities, understood as multifactorial preparation. The objective was to analyse the effects of training (aerobic and continuous) on the leg power, fatigue levels, speed, agility, body fat, muscle mass and bone mass of these players. Methods. Seventy-two soccer players, male and under 17, from 4 teams that participated. The teams performed 3 times a week training sessions of about 60 to 90 minutes each. Informed consent requests were given to their parents for authorisation to participate in this investigation. Data was collected in two different time points, about ten months apart. Specific tests were performed for each variable: the vertical jump with Bosco System for leg power, the T-Test for agility, the linear sprint test for speed and the RAST test for fatigue levels. A precision Tanita scale was used for the anthropometric tests such as body fat, muscle mass and bone mass. Statistical procedures were applied through the Wilcoxon test to compare the two time points of evaluation. Conclusions: the implemented training improved all the analysed variables with significant statistical values for leg power, speed, bone mass, muscle mass and fat mass.
- Physical Exercise related to student’s academic performancePublication . Honório, Samuel; Batista, Marco; Santos, Jorge; Vandoni, MatteoAcademic performance is a topic of extreme relevance given the fact that it influences many other areas of children's and adolescents' lives. Academic performance is defined as a concrete assessment of the knowledge obtained by students. In practice, it refers to the results of assessment evaluations that teachers apply in the school context. The evaluation is then a classification that is attributed to the works and tests carried out for the school context and that informs students, parents, teachers and the community in general of the learning acquired by the student. The purpose of evaluation is to certify, assess and verify the degree of achievement of these objectives. It can also be added that the objective of this evaluation is to summarize the performance of the students, in a group of strategies and learning objectives and that it was designed so that it is possible to make decisions about the results of those evaluated. Academic performance is then the externally evaluated result achieved by the student. Several variables have been associated with school results, that is, academic performance, self-esteem, self-concept, parents' education as well as their involvement in the children's lives, and the sociocultural context in which the child or adolescent is inserted. In this sense, physical exercise has been reported to increase academic performance, assertiveness, confidence, emotional stability, intellectual functioning, memory, perception, positive body image, self-control, well-being and efficiency at work. Physical exercise can help children to achieve higher academic performance levels and postulate that while high-intensity, short-term exercise promotes mental and intellectual functioning, long-term strenuous exercise can inhibit the subject's performance, unless he possesses high physical aptitudes. The practice of physical exercise in schools promotes an increase in muscle tension, which is a facilitating element in the performance of various psychological tasks. In their study, subjects submitted to physical exercise show faster acquisition and evolution of meaningless syllables and a greater ability in terms of learning/memorizing associated pairs, greater accuracy in solving simple mathematical problems and greater efficiency in a test perceptive color naming than subjects who perform the same tasks under normal conditions. Some studies suggest, however, that exercise can help students improve their academic performance through a variety of approaches and strategies, considering that when someone feels good physically, they are able to function at a higher level academically.
