- 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.
- 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.
- 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.
- Comparison of physical fitness levels and body mass index in students from 5th to 9th grade in Physical Education classes depending on urban or rural residence placePublication . Costa, Aldo; Resende, Ana; Honório, Samuel; O'Hara, Kelly; Martins, Júlio; Vicente, AntónioIntroduction: The main purpose of this study was to have a comparison of the physical fitness levels and body mass index of students with urban and rural residence from an elementary school in Portugal. Methods: The sample covered 270 students, 142 male and 128 female, aged between 9 and 16, from the 5th to the 9th grade. The Fitnessgram test battery (NES, 2002) measured the physical fitness, the body mass index was based on the reference values from the World Health Organization (1995) and the students' characterization was assessed through the biographical archives given by the school. Results: The test results only demonstrated significant differences (p <0.05) amongst these students: Females in the 5th and 6th grade in the following tests, trunk extension with better results in students with rural residence and middle strenght with better results in students with urban residence; Males in the 5th and 6th grade in the following tests: the shuttle run with better results in students with rural residence; Females between 7th and 9th grade in the following tests: trunk extension with better results in students with urban residence. Conclusions: Significant differences were not observed between the levels of physical fitness and BMI related to the place of residence (rural and urban).
- Self-esteem, self-concept and academic performance in middle-school students according to their sport contextPublication . Honório, Samuel; Ramos, Luís de Sousa Aguilar; Santos, Jorge; Serrano, João; Petrica, João; Batista, MarcoIntroduction: Academic performance is favored in students who practice sports with body contact and develops an increasing value in self-concept when a comparison is established with those who don’t are engaged in sports without body contact. Methods: This study aimed to analyze and relate variables of self-concept, self-esteem and other variables such as aerobic capacity (VO2 max), handgrip strength and academic achievement, within the modalities that they practiced, with and without body contact. 132 middle-school students between 10 and 11 years old (69 boys and 63 girls) who attended the 5th and 6th grades participated. Results: It was found a mean level of behavior, physical appearance, school competence, social acceptance and higher academic performance in the group without body contact. A T-test was applied on self-concept variables, self-esteem, aerobic capacity (VO2 max) and academic performance, and the Mann-Whitney test on physical appearance variables and handgrip strength, finding only differences in the behavior variable, with a value of α = 0.014. A linear regression analysis was also presented in order to identify the best predictors of academic performance Conclusions: The practice of sports with body contact promotes a significant increase in behavior levels, compared to students without body contact, however the practice of this type of sports doesn’t show higher levels of self-esteem and academic performance, once compared to other students practicing sports without body contact. The best predictors identified were global self-concept, school competence and aerobic capacity.
- DE-PASS Best Evidence Statement (BESt) : modifiable determinants of physical activity and sedentary behaviour in children and adolescents aged 5-19 years : a protocol for systematic review and meta-analysisPublication . Khudair, Mohammed; Marcuzzi, Anna; Ng, Kwok; Tempest, Gavin; Bartos, Frantisek; Peric, Ratko; Cardon, Greet; Carlin, Angela; Castagna, Carolina; Chaabene, Helmi; Chalkley, Anna; Ciaccioni, Simone; Swider, Joanna; Čingienė, Vilma; Corvino, Chiara; Baldassare, Angela di; Drid, Patrik; Gallé, Francesca; Gebremariam, Mekdes; Goudas, Marios; Honório, Samuel; Izzicupo, Pascal; Jelsma, Judith; Kolovelonis, Athanasios; Kouidi, Evangelia; Masanovic, Bojan; Mork, Paul Jarle; O’Hara, Kelly; Palumbo, Federico; Prieske, Olaf; Ribeiro, José Carlos; Rumbold, Sheena; Sorić, Maroje; Syrmpas, Ioannis; Van Hoye, Aurélie; Woods, Catherine; Capranica, Laura; Ling, Fiona Chun Man; Cortis, Cristina; Geus, Eco J.C. de; Credico, Andrea di; Tarazaga, Fernández; García Sánchez, Esther; Hayes, Grainne; Jahre, Henriette; Juric, Petra; Kongsvold, Atle; Mansergh, Fiona; Mekonnen, Teferi; Murphy, Marie; Torun, Ayse Ozbil; Popovic, Stevo; Puharic, Zrinka; Louise, PennyIntroduction: Physical activity among children and adolescents remains insufficient, despite the substantial efforts made by researchers and policymakers. Identifying and furthering our understanding of potential modifiable determinants of physical activity behaviour (PAB) and sedentary behaviour (SB) is crucial for the development of interventions that promote a shift from SB to PAB. The current protocol details the process through which a series of systematic literature reviews (SLRs) and meta-analyses (MAs) will be conducted to produce a best-evidence statement (BESt) and inform policy makers. The overall aim is to identify modifiable determinants that are associated with changes in PAB and SB in children and adolescents (aged 5-19 years) and to quantify their effect on, or association with, PAB/SB.
- Small-sided games for technical and tactical development in young rink hockey playersPublication . Honório, Samuel; Batista, Marco; Santos, Jorge; Serrano, João; Petrica, João; Almeida, João Fernando Baptista; Camões, MiguelRink hockey like any other team sport game is necessary to have a mastery of the game object "the ball" and for this it is necessary that athletes do not have a deficient training steps in that process, because it is during their development, that the athlete is in an optimal situation to improve on this aspect of the game. The study objective was to identify which game model allows young athletes to have a greater number of interactions with the ball in rink hockey in the levels of “Under 8” and “Under 10”. Our study sample consisted of 24 games: 8 games in the 3x3 model; 8 games in the 4x4 model and 8 games in the 5x5 model. The 24 matches are equally divided by the levels of Under 8 and Under 10 with a total of 88 children participating. For data collection instrument we used the deferred observation method where we proceeded to a descriptive analysis of the data to find the means, standard deviation and totals of: Shots, Passes, Interceptions and Goals. The Mann-Whitney and Kruskal-Wallis tests were used for comparisons and for correlations, the Spearman's Test was used to verify whether as the playing area available to the player increased, the player's actions increased as well. The 3x3 model obtained a total of 911 actions, the 4x4 model obtained 923 and the 5x5 game model obtained 799 game actions. The 4x4 game model obtained the highest total number of game actions in all levels analysed suggesting that the implementation of this model brings benefits to the athletes.
- The Daily Life´s Routines of Children with DisabilitiesPublication . Mesquita, Helena; Serrano, João; Honório, Samuel; Batista, Marco; Ribeiro, Jaime MoreiraThe objective of this research is to know the activities, the routes, the places visited and the obstacles identified in daily life routines of children / youth with disabilities, living in urban environments, during the time in which they are off the school period. In methodological terms, we used as instruments of study an anamnesis fact sheet and a routine diary that was completed by the parents together with the child / youth, an Individual Educational Plans (IEP) and a semi-structured narrative interview. Eight subjects between the ages of 9 and 15, all with different pathologies, were part of the study. The study was exploratory, descriptive and analytical. The results demonstrated that the subjects are supported in their routines by their parents and other relatives. Weekly out-off-school routines are primarily focused in the home (meaningful and important place) with activities classified mostly as sedentary ones in which they use little materials and in the places where they perform specific activities (Therapies, Tutoring, Music Conservatory and Catechism). The age and pathologies associated with each subject are factors that influence autonomy and independence of mobility. They visited few places and did so mainly in the company of family members. The main obstacles encountered in the routes performed are closely related to their pathology, showing difficulties in interacting with their peers. We conclude that the children / young people who participated in the study engaged in few activities and these were mostly in the home and sedentary. They visit few places, have poor independence of mobility, and interact poorly with others.
