- Attention in physical education classes: differences between colletive sportsPublication . Santos, Jorge; Petrica, João; Serrano, João; Batista, Marco; Honório, Samuel; Lercas, Afonso Jorge Vicente; Maia, LuisAttention is considered an important mediator variable in the teaching / learning process, because of that, the scientific community made several investigations in order to understand what students are thinking, what strategies are best to captivate their attention and the type of instructions and/or feedback to develop students’ performance in achieving motor skills. In this research we tried to find differences in attentional profiles, of students during the practice of football and basketball at different moments of a Physical Education class. The sample consists of 156 students of both genders (84 females and 72 males), between 12 and 16 years old ( of 3rd Primary School (7th, 8th and 9th grade) to which a questionnaire was applied, ATEST- EF (Petrica 2010). Questionnaire which students had to point out what they were thinking at certain time of the Physical Education class. This was applied in team sports (football and basketball). In descriptive terms we found that students are in general aware of the task, information and behavior, and there are a few differences between the percentages between them, but from the test Chi_Square we found no statistical differences between the different moments of the Physical Education class. We concluded that, in this sample we didn’t verified the importance of attention and students focus in the different moments of team sport’s practice
- Exercise and academic performance : implications of aerobic capacity and hand grip strength in middle-school studentsPublication . Honório, Samuel; Ramos, Luís de Sousa Aguilar; Santos, Jorge; Serrano, João; Petrica, João; Batista, MarcoAbstract: The regular practice of physical exercise has a positive role on mental health and a positive contribution to the development of cognitive function, considered beneficial to academic performance. The present study aimed to analyse the impact of physical exercise on students' academic performance. 227 students participated, of which 112 (49.3%) were male and 115 (50.6%) were female, aged between 10 and 13 years old, from 5th and 6th grades in a Portuguese public school. The Susan Harter Self-Concept Scale validated for the Portuguese population was used, and a descriptive and inferential analysis of the data was conducted to analyse the levels of handgrip strength, aerobic capacity and academic performance. Linear regression analysis was used to interpret the predictive variables and we calculated the magnitude of the effect. The results suggest that the practice of physical exercise enhances the levels of aerobic capacity, handgrip strength and academic performance of students. In addition to physical education classes, the individual sports combined with the team sports present very positive values in relation to the variables described.
- The influence of obesity on the motor coordination in children between 6 and 9 years of age.Publication . Martins, Júlio; Landeiro, João; Martins, João; Honório, SamuelObesity is the most common childhood illness in developed countries and its prevalence continues to increase. The objective was to analyze the influence of obesity on the motor coordination of children between 6 and 9 years old. Equipment and Methods: A number of 52 pupils of both genders participated for evaluation of the prevalence of obesity using the measurement of the abdominal perimeter and the Body Mass Index (BMI) categorized as Normal-Weighted, Excess Weight and Obesity. The assessment of motor coordination was performed by the KTK test. SPSS (version 19.0) was used for statistical purposes. Results: Girls had lower levels of performance rather than boys, and the pupils presented worse levels of motor performance as the age progressed. Regarding the prevalence of obesity, the two-gender obtained high mean values for the Normal-weighted category, whereas 25% is overweight. Regarding the level of motor coordination, 57.7% of the pupils had Normal Coordination and 40.4% had coordinative difficulties. Pupils with higher values of BMI and abdominal perimeter obtains lower results of motor coordination.
- Physical fitness levels in students with and without training capacities – A comparative study in physical education classes.Publication . Martins, Júlio; Honório, Samuel; Martins, JoãoIntroduction: The practice of Physical Activities is a cultural habit and as such it must be acquired in childhood so that there is a greater probability of being continued throughout life. Physical Activities on a regular and duly regulated basis, even if they are at ages where this component is absolutely fundamental, not only for their motor development but for their socialization and creation of healthy lifestyles. Objective: The study aims to evaluate the levels of Physical Fitness of middle-school students, between students who practice Physical Education and those who, in addition to this, performed a training programme. Methods: Participated 32 students of both genders aged between 10 and 11 years old divided into two groups with the same number of students (16): the Training Group which, in addition to attending Physical Education classes, benefited from a training programme and the other group that only attended the physical education classes. The Fitnessgram battery tests was applied for flexibility, strength and aerobic capacity. Results: Through this study, it was presented that the use of a physical training programme, eight weeks before the final moment, allowed the training group to obtain significant differences, in the tests results, from the initial moment to the final moment in terms of physical fitness when compared with the group that only attended physical education classes. Conclusions: This study allows us to understand that the fact that the Training Group benefited from a Physical Skills Training, improved the performance levels of the students in this group at the final moment.
- Supervisão Pedagógica em NataçãoPublication . Honório, Samuel; Batista, Marco; Serrano, João; Petrica, João; Santos, Jorge; Rocha, JoãoEm termos de práticas de ensino, a prática pedagógica supervisionada, é efetivamente uma sólida estratégia de formação, onde a competência dos formadores supervisores e o tipo de relações supervisivas que se estabelecem neste processo são determinantes. Os autores abordados consideram que o processo de Supervisão pode ser considerado como um processo de resolução de problemas, em que o observador e o observado desenvolvem formas de resolução de tarefas através de estratégias técnico-didáticas adequadas num contexto afetivo-relacional adequado envolvido numa atmosfera favorável. São vários os fatores que determinam e influenciam diretamente o ensino da natação: A relação professor-aluno em natação depende da sua capacidade ou habilidade em comunicar com os seus alunos; Criar um ambiente seguro, com um domínio exímio dos conteúdos técnicos, uma estratégia de ensino adequada a cada situação de aprendizagem são a chave para o tipo de trabalho que se pretende em natação. A modalidade específica da natação requer procedimentos e intervenções específicas que se prendem essencialmente com a transição para o meio aquático, ou seja, dotando os professores de capacidades interventivas na modalidade, cujos padrões técnicos e metodologias de ensino se tornam necessárias para dominar e promover um ensino de sucesso.
- Sistemas de fornecimento e gastos de energia no exercício físico : uma revisãoPublication . Honório, Samuel; Santos, Jorge; Serrano, João; Petrica, João; Rebelo, Miguel; Vieira, Fernando; Batista, MarcoMuitas atividades desportivas, recreativas e ocupacionais requerem uma libertação de energia moderada a intensa e contínua. O fracionamento aeróbio de carboidratos, gorduras e proteínas fornece energia para o exercício devido à fosforilação do difosfato de adenosina (ADP) em trifosfato de adenosina (ATP). Um desequilíbrio energético anaeróbio-aeróbico se instala na ausência de um ritmo estável (steady rate) entre a fosforilação oxidativa do ADP em ATP e a energia necessária para o exercício. Quando há um desequilíbrio, a acidez dos tecidos aumenta e eventualmente manifesta-se um estado de fadiga. Dois fatores influenciam a forma como os indivíduos são capazes de manter um elevado nível de atividade física com o mínimo de fadiga: a capacidade e integração dos sistemas fisiológicos para fornecer oxigénio e a capacidade de fibras musculares específicas ativadas durante o exercício para gerar ATP aeróbica.
- 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.
- Differences in the Development of Motor Skills in Portuguese Children Aged 12 Months after 3 Years of COVID-19 ConfinementPublication . Rebelo, Miguel; Paulo, Rui; Honório, Samuel; Petrica, João; Batista, Marco; Duarte-Mendes, Pedro; Marques, Catarina; Serrano, João(1) Background: The objective of the study was to verify the effects of COVID-19 confinement on motor skills through a longitudinal study in Portuguese children who were one year old at the beginning of the pandemic. (2) Methods: The sample consisted of 88 children of both sexes, in the pre-COVID-19 assessment, they were 13.31 ± 2.4 months old and in the post-COVID-19 assessment, the same children were already 49.31 ± 2.5 months old. Motor skills were assessed using the PDMS-2 scales. For the statistical analysis, the Kolmogorov–Smirnov test was used to test normality, and the Wilcoxon test was used to compare the results of the two assessments in the same sample. (3) Results:There were statistically significant differences in all motor skills assessed, with children presenting, on average, worse results in all global motor skills in the post-COVID-19 assessment, as opposed to fine motor skills, showing better results in the post-COVID-19 assessment. (4) Conclusions: These results show the negative impact of the pandemic on children evaluated with a special emphasis on global motor skills, with the majority demonstrating values considered below average for their age, noting that the pandemic protocols may have had serious consequences on children’s motor development, warning professionals who deal daily with children in these age groups about the importance of stimulating global motor skills.
- Motivation trans-contextual model application in the prediction of veteran athlete’s life satisfactionPublication . Batista, Marco; Honório, Samuel; Leyton, Marta; Jiménez Castuera, RuthBACKGROUND: This work presents an application extension of the motivation Trans-contextual Model, specifically in the prediction of veteran athletes’ life satisfaction. METHODS: A sample of 682 Portuguese veteran athletes of both genders, aged between 30 and 76 years old (M=43.64; SD=8.25) were used, in which, through questionnaires, the following was measured: basic psychological needs satisfaction, motivation, variables of planned behavior and life satisfaction. RESULTS: The structural equations model showed that social relation perception predicts positively and significantly autonomous motivation. In turn, it predicts attitudes positively and significantly, subjective norms and control perception, predicting these, positively and significantly the intentions. Satisfaction with life is positively and significantly predicted by intentions and control perception. CONCLUSIONS: From the results reached in this study, it is important to emphasize the importance of fostering social relations, since this will favor autonomous motivation, promoting a higher behavioral control over the practitioners’ intentions, generating greater life satisfaction.
- What are students thinking in Physical Education classesPublication . Santos, Jorge; Batista, Marco; Serrano, João; Honório, Samuel; Ivone, RenteAttention is also considered an influential mediating variable because it influences the teaching-learning process, as well as the teacher's behavior, the student's behavior, and the learning results. According to this factor, focused attention arises as a funda- mental condition of the learning process since the greater the ability to maintain focus on a particular object or task, the better the chance of success. Objective: To know the aspects the students pay attention to during the different moments of the Physical Education class. Methods: The sample consisted of 156 students from the 7th, 8th, and 9th grades of high school, of both genders (84 female and 72 mal, = 14,9 ± 1,3 ). The questionnaire ATEST-EF (Petrica, 2003, 2010) was applied, in which the students signalized their thoughts at certain moments of the Physical Education classes. Results: The results indicate that there are no significant differences because after the application of the "Qui-Square" test to associate the variable "Attention" and the variable "Signal," it verified the value of (p= .373). Discussion: From the analysis performed, it was observed that there are no significant differences concerning students' attention profile study. Only a small magnitude of size effect (d = 0.219) was observed at the level of the general attention profile. Conclusions: It was concluded that student's attention during the physical education class is mainly focused on the task and with less attention focused on things outside the class regardless of their academic performance.
