- 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.
- Attention in physical education classes: Differences between different individual modalitiesPublication . Santos, Jorge; Maia, Luis; Petrica, João; Serrano, João; Batista, Marco; Honório, SamuelIntroduction: Sport activities demand a focused and polarized attention, as necessary condition to learning process. Described as an essential condition to the learning process, attention is considered a powerful mediating variable, because we can notice its influence on the teaching-learning process, as well as its influence on the teacher’s behaviour, the student’s behaviour and the learning results. According to this fact, the focused attention arises as a fundamental condition to the learning process, since the greater the power to keep the focus on a certain object or task, the better the chance of success. Objective: We intend to know the aspects to which the students pay attention during the different moments of the Physical Education class, in individual sportive activities. Methodology: The sample consisted of 156 students from the 3rd Cycle of Basic Education, of both genders (84 female and 72 male). We applied the questionnaire ATEST-EF (Petrica 2003), in which the students signalized what they were thinking of at certain moments of the Physical Education classes, more precisely of Athletics and Gymnastics classes. The results indicate that there are no significant differences, because after the application of the test of “Chi-Square” to associate the variable “Attention” and the variable “Signal” for the individual activities, we can verify the value of (p= .373). From the analysis performed, we can infer that in relation to students' attention profile study in individual sportsathletics and gymnastics, there are no statistically significant differences.
- Effects of swimming and water walking on body composition and spirometric values in young childrenPublication . Honório, Samuel; Duarte-Mendes, Pedro; Batista, Marco; Serrano, João; Paulo, Rui; Oliveira, João Filipe Moiteiro Dias de; Petrica, João; Santos, JorgeAquatic activities have been recommended as frequent practices due to the physical properties of water with improvements in body composition of young. Objective: To study if there are differences in body composition and spirometric values in children who practice swimming complemented with water walking and those who only practice swimming. Methodology: 28 individuals (6 to 12 years) were divided into two groups: swimming group (SG: n=9) and swimming complemented with water walking group (SWWG: n=19) in three different moments with 6 weeks between them. For body composition a bio-impedance scale was used and an anthropometric tape for the waist circumference. For spirometric values: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and even peak expiratory flow (PEF) a Cosmed Microquark spirometer was used. For statistical procedures the SPSS (20.0) program for descriptive statistics, the Shapiro Wilk test for testing the normality, inferential statistics (non-parametric Mann-Whitney tests, Friedman's Anova), and for the effect size the d-Cohen test. Results: Regarding the inter-group analysis (comparison between the SG and SWWG) we observed that there were significant differences in weight (p=0,004), forced expiratory volume in 1 second (FEV1: p=0,025) and peak expiratory flow (PEF: p=0,033). Concerning intra-group differences (improvements in the SG and SWWG), the SWWG showed significant improvements in weight muscle mass (p=0,029), fat mass (p=0,002), percentage of water (p=0,018),, body mass index (BMI: p=0,000), body percentiles (p=0,000), forced vital capacity (FVC: p=0,003) and forced expiratory volume in 1 second (FEV1: p=0,008). We have concluded that the practice of swimming and water walking have benefits with differences in the analysed group variables, however, the two activities complemented (swimming and water walking) present improvements much more significant.
- 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.
- Gender differences in self-determined motivation and subjective well-being of adapted sport athletes members of the special with intellectual and developmental difficulties members.Publication . Domingues, Ana Margarida Martins; Santos, Jorge; Serrano, João; Batista, Marco; Petrica, JoãoThe Theory of Self-Determination has been used as a theoretical model of support in several studies on motivation in Sport. In this sense, we realize that motivation is a topic to which researchers have devoted much of their time, however, when researching adapted sports, and the person with Intellectual and Developmental Difficulty we observe a shortage in research.This study aimed to verify the levels of self- determination and subjective well-being of athletes members of the Special Olympics of Portugal, and ii) to compare the variables under analysis according to gender. In this quantitative study participated 94 athletes of Adapted Sports, aged between 11 and 63 years (‹=32.61 ± SD=13.8) of both genders, competitors of individual and collective sports.The monitoring instruments used were Behavioral Regulation in Sport Questionnaire (BRSQ), Basic Psychological Needs Exercise Scale (BPNES), Life Satisfaction Scale (S WLS) and Positive and Negative Attachment Scale (PANAS). Data analysis was based on the verification of the internal consistency of the scales applied through the calculation of alpha and Cronbach, descriptive analysis of data and application for gender comparison through the nonparametric test U Mann- Whitney, as well as a linear regression, meeting a significance level of 0.05. As a result, we observed that the satisfaction of basic psychological needs and motivation predict good levels of life satisfaction also of positive attachment.We also found statistically significant differences in life satisfaction and negative attachments when comparing gender outcomes.
- Self-perception of quality of life and practice of physical activityPublication . Santos, Jorge; Petrica, João; Serrano, João; Batista, Marco; Honório, SamuelPopulation aging is an increasingly observable fact in several developed countries. In Portugal, the percentage of elderly people is much higher compared to other age groups. We know that this phase of life causes damage at the biological level, psychological and social problems, which means that the quality of life at this age can decrease. Physical activity can be a means of reversing and / or preventing loss of quality of life. This study aims to verify whether elderly people who practice a regular program of formal physical activity have a better perception of their quality of life than non-practicing elderly people. The sample consisted of 64 elderly people (n = 64), residing in Proença-a-Nova in Portugal, divided into two groups, a group of practitioners in elderly programs and another group not practicing formal physical activity. The perception of quality of life was measured using the MOS SF-36v2 questionnaire, while the battery of tests by the Senior Fitness Test by Rikli and Jones (1999; 2001) was used to assess the functional level. The results showed that the perception of quality of life presents few statistically significant differences, with the highest values being that of the group of practitioners. The perception of quality of life reveals a weak correlation with the functional level presented by the two groups. It was concluded that the practice of physical activity does not influence the perception of quality of life, but it has a significant influence on a better functional level.
- Modalidades deportivas elegidas por los futuros profesores para sus práticasPublication . Petrica, João; Serrano, João; Mesquita, Helena; Santos, JorgePretendíamos saber quais foram as modalidades desportivas escolhidas para a realização das atividades de formação em ensino, se os professores escolhiam para leccionar matérias diferentes das professoras e se as escolhas efectuadas para as aulas de interior eram diferentes das aulas de exterior. Para tal foram observadas sessenta lições de microensino leccionadas por estudantes de Educação Física, sobre um tema em que se sentissem mais à vontade e no local por que optassem. Verificámos que, na sua maioria, escolhem a ginástica como matéria, conteúdo, ou tema da lição e, por isso, preferem leccionar as suas aulas no interior, isto é, numa instalação desportiva coberta, e os restantes optam pelos desportos colectivos, sensivelmente na mesma proporção para cada uma das modalidades andebol, basquetebol, futebol ou voleibol, e são muito poucos os que escolhem o atletismo para praticarem as suas habilidades, competências ou destrezas de ensino.
- Preditores motivacionais de bem-estar subjetivo em adultos ativos praticantes de ginásioPublication . Batista, Marco; Vitorino, Guida Daniela Laranjeira; Honório, Samuel; Santos, Jorge; Serrano, João; Petrica, JoãoO objetivo deste estudo foi determinar preditores motivacionais de bem-estar subjetivo em adultos ativos praticantes de ginásio, tendo por base a teoria da autodeterminação. Participaram neste estudo 348 sujeitos, 174 de ambos os sexos, entre 18 e 67 anos (M=31.83 DP=12.86), com 4.37 anos de média de prática de atividades de ginásio, maioritariamente a treinar 3 vezes por semana, com 310.11 minutos médios semanais. Utilizou-se a escala das necessidades psicológicas básicas no exercício, o questionário de regulação comportamental no exercício, a escala de satisfação com a vida e a escala de afetos positivos e negativos. Elaborou-se uma estatística descritiva, correlação de Spearman e regressão linear por blocos. Os valores médios mais elevados foram registados na necessidade psicológica básica de autonomia, na motivação autónoma e na satisfação com a vida. Registaram-se correlações positivas entre as necessidades psicológicas básicas, motivação autónoma, satisfação com a vida, afetos positivos e o volume de minutos de treino semanal. Observaram-se igualmente correlações positivas entre a motivação controlada, amotivação e afetos negativos. A análise de regressão linear permitiu- nos verificar que as necessidades psicológicas básicas explicam um valor percentual mais elevado a variabilidade dos dados da satisfação com a vida e afetos positivos, comparativamente com a motivação.
