The main purpose of this study is to present objective data on the differences in anthropometrics and fitness variables between adult athletes and non-athletes with Down Syndrome (DS) members of the “Down Cordoba Association” (DCA), after adjusting for confounders. Twenty-seven adults, 7 athletes and 20 non-athletes with DS, participated in this study. Health-related fitness variables were measured with tests validated for this population. First, the characteristics of the subjects according to sex and sports practice are presented. Athletes present significantly higher values for height (p = 0.010) and waist-to-hip ratio (p = 0.005). Furthermore, male athletes compared to male non-athletes have lower values in % of body fat (p = 0.030), and in waist (p = 0.031) and hip (p = 0.041) circumferences. Furthermore, athletes have better values in tests of strength, cardiovascular endurance (66.60 ± 47.66 vs. 32.31 ± 24.49 (s); p = 0.037), and agility, but not in flexibility. Significant differences were only found in cardiovascular endurance. As a conclusion, the practice of sports among the users of the “Down Córdoba Association” in general leads to better health-related fitness values. Therefore, we encourage the guardians of people with DS in this association to motivate them to practice sports because this practice will more likely improve their overall health.

Within the determining factors of psychological performance, mental toughness is considered a multidimensional factor, comprising cognitive, affective, and behavioural components together with self-confidence, which is related to success in sports performance as well as psychological health and well-being. The aim of this study was to analyse the relationship between different factors composing mental toughness and age categories in young football players, in order to determine the presence of specific psychological skills in their formative progression. A total of 118 male players (16.91 ± 2.42 years old) completed the Spanish version by Cernuda (1988) of the original Psychological Performance Inventory (PPI) by Loher (1982, 1986). The results indicated significant differences in four variables (negative energy control, attention control, visual and image control, motivational level) on three different age categories, where the U19 category showed the best results for all the variables, decreasing afterwards in the semi-professional category. Significant correlations were established between mental toughness variables and age categories, where the age category variable was significantly correlated in a positive way with attention control, visual and image control, and motivational level. In the same line, the variable self-confidence correlated positively with negative energy control, attention control, motivational level, attention control, and positive energy. The assessment of psychological variables such as mental toughness, taking into account the formative stage, may be helpful for both coaches and players when selecting adequate mental skill training for improving competitive performance and sporting success, as well as for positive and healthy psychological development and well-being.

(1) Background: Cyberbullying is a social concern in adolescents. The practice of physical activity is a key factor in protection against cyberbullying related to the multiple psychological benefits. Therefore, the study sets out to analyse the relationship between amount, types, enjoyment of physical activity and performance in physical education with cyberbullying. (2) Methods: A sample of 867 adolescents between 12 and 19 years of age from two schools in Andalusia (Spain) was studied. A computer-based questionnaire given in the classroom was used, with two questions about the type of physical activity, one on physical education performance, the Scale of Enjoyment of Physical Activity (PACES) and the Spanish version of the European Cyberbullying Intervention Project Questionnaire (ECIPQ). (3) Results: Clear relationships were found between the practice of physical activity and cybervictimisation. However, less involvement has been observed among girls who practice physical activity in cyberaggression. (4) Conclusion: In relation to the types of physical activity, it seems that practising physical activities that involve competition can help to develop defence mechanisms against cyberaggression, as well as improve values to be less involved in cyberaggression.

O bullying é um problema social caracterizado pela agressão intencional que ocorre ao longo do tempo, geralmente em contextos escolares e no ciberespaço (cyberbullying). Tem havido um interesse crescente na prevenção deste fenômeno, a fim de reduzir os efeitos adversos. Diferentes estudos e relatórios sugerem que o tema da Educação Física pode ser um cenário de interesse para promover atitudes e comportamentos contra o bullying. O objetivo deste trabalho é examinar o estado da questão nesta área através de uma revisão da literatura científica. Com base na análise das evidências, concluímos fazendo recomendações sobre estratégias e habilidades que devem ser incluídas nos currículos de Educação Física para prevenir o bullying e o cyberbullying. Dentre as mais utilizadas, destacamos as metodologias cooperativas, uma atitude de ensino que promove um clima motivacional focado na tarefa e a integração curricular de recursos didáticos que abordam habilidades e fatores de proteção.

Background: The aim of the present work is the elaboration of a systematic review of existing research on physical fitness, self-efficacy for physical exercise, and quality of life in adulthood. Method: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines, and based on the findings in 493 articles, the final sample was composed of 37 articles, which were reviewed to show whether self-efficacy has previously been studied as a mediator in the relationship between physical fitness and quality of life in adulthood. Results: The results indicate that little research exists in relation to healthy, populations with the majority being people with pathology. Physical fitness should be considered as a fundamental aspect in determining the functional capacity of the person. Aerobic capacity was the most evaluated and the 6-min walk test was the most used. Only one article shows the joint relationship between the three variables. Conclusions: We discuss the need to investigate the mediation of self-efficacy in relation to the value of physical activity on quality of life and well-being in the healthy adult population in adult life.

Background: Bullying is a social problem where there is a phenomenon of intentional aggression that occurs in all schools. It has multiple negative consequences for the victim’s psychological health. As school is a context for learning about life in society, strategies to prevent such attitudes and behaviours should be encouraged. Although some studies seem to indicate the potential of the subject of physical education to promote attitudes and behaviours against bullying, there is still insufficient scientific evidence to deduce a positive impact on the reduction or prevention of this phenomenon. Purpose: This study aimed to analyse the effectiveness of a specific intervention to prevent bullying in Physical Education classes in Secondary Education. 6 specific sessions inserted into the physical education curriculum to find out what bullying is, who its protagonists are and how to prevent it. Participants and setting: In the study, 764 students with an age range of 12–19 years (49.3% girls; age mean [M] = 14.80, standard deviation [SD] = 1.69) from two public educational centres participated. Among them, 439 were randomly assigned to the quasi-experimental group (48.1% girls; age M = 14.70, SD = 1.59) and 325 to the control group (51.1% girls; age M = 14.94, SD = 1.83). Data were collected at two timepoints, pre- and the post-intervention data. Data collection: The Spanish version of the European Bullying Intervention Project Questionnaire (EBIPQ) was used to measure the incidence of bullying. To measure cyberbullying, the Spanish version of the European Cyberbullying Intervention Project Questionnaire (ECIPQ) scale was used. Data analysis: The Student t-test was performed to compare possible differences between the experimental and control groups in the pre-test. To compare the means of the factors obtained based on the variables and the instruments used, as well as the scores obtained from the subjects of the experimental and control groups at the two timepoints, linear models of repeated measurements have been established comparing the pre- and post-intervention moments and the experimental and control groups, introducing sex and grade variables to compare the effectiveness of the programme based on them. Results: There were no differences in the pre-test measurements in any of the variables. After the intervention programme in the quasi-experimental group, the bullying victimisation (F = 16,951; p = .000) and bullying aggression (F = 5,215; p = .023) rates decreased significantly more than they did the control group. Likewise, victimisation in cyberbullying (F = 6,234; p = .013) decreased significantly differently, but aggression in cyberbullying did not (F = 0,099; p = .753). Conclusion: The implementation of a specific intervention to prevent bullying inserted into the physical education curriculum seems to have decreased bullying and cyberbullying victimisation.

Fitness in adolescence is closely related to health even in adulthood. Fitness can be improved with the practice of physical activity however other factors cannot be modified as in the case of birth weight or breastfeeding. In this study we measured fitness of 233 students 14.76 (± 0.84) years through tests of the Eurofit battery such as 20 meter shuttle run test, horizontal jump, sit and reach, sit up 30 seconds, handgrip strength agility (4 × 10) and anthropometric data. Furthermore, we asked the birth weight and breastfeeding time. The results showed no significant differences in terms of breastfeeding, there were only differences in the boys in the sit up test (breastfeeding was related with better scores) and girls in flexibility (breastfeeding was related with lowers scores). Regarding the boys birth weight, a positive relationship was found between the anthropometric data and the dynamometry test; and the weight at birth. In girls, however, differences were found in several physical fitness tests with positive relationships in the aerobic endurance, hand grip strenght, sit up and horizontal jump tests. In conclusion birth weight was related with better fitness scores in girls. Additionally, for boys we found relationship with anthropometric variables. On the other hand, the time of breast milk intake did not seem to show a clear association with any of these variables. La forme physique durant l’adolescence est intimement liée à la santé, et ce même durant l’âge adulte. La forme physique peut être améliorée grâce à la pratique d’une activité physique. Cependant, d’autres facteurs ne peuvent pas être modifiés, comme c’est le cas pour le poids de naissance ou l’allaitement au sein. Lors de cette étude, nous avons mesuré la forme physique de 233 collégiens de 14,76 (± 0,84) ans à travers des essais issus de la batterie de tests Eurofit: le test de course navette sur 20 mètres, le saut à l’horizontale, le sit and reach (flexions du tronc), les redressements sur 30 secondes, l’agilité et la force de poigne (4 × 10) ainsi que des données anthropométriques. D’autre part, nous avons demandé le poids de naissance et la durée de l’allaitement au sein. Les résultats démontrent qu’il n’y a pas de différences significatives en ce qui concerne l’allaitement au sein, mais qu’il existe seulement des différences chez les garçons durant le test de sit up (l’allaitement au sein est lié à de meilleurs résultats) et chez les filles durant le test de souplesse (l’allaitement est lié à de moins bons résultats). En ce qui concerne le poids des garçons, un rapport positif a été démontré entre les données anthropométriques et le test de dynamométrie, et le poids de naissance. Cependant, chez les filles, nous avons pu trouver des différences parmi plusieurs tests de forme physique avec les rapports positifs dans les tests d’endurance aérobie, la force de poigne, le sit up et le...

Tissue damage resulting from oxidative stress induced by a pathological condition might have more serious consequences in children than in adults. Researchers have not yet identified particular markers — alone or in combination with others — of oxidative stress, or their role in pediatric diseases. The aim of this study was to identify gender-based biomarkers for measuring oxidative stress. Oxidative biomarkers were studied in 138 healthy Spanish children (85 boys, 53 girls) 7 to 12 years of age, at the prepubertal (Tanner I) stage, independent of body mass index (BMI), age, fitness (measured by 20-m shuttle run test), and physical activity (measured by participation in an after-school exercise program). The oxidative biomarkers measured were lipid peroxidation products, total nitrites, protein carbonyls, and oxidized glutathione (GSSG). The antioxidant biomarkers measured were total glutathione (TG), reduced glutathione (GSH), superoxide dismutase activity (SOD), and glutathione peroxidase activity. In the study population, height, weight, waist circumference, and BMI were lower in girls than in boys. For oxidative biomarkers, boys had higher levels of protein carbonyl than girls (p < 0.001). In spite of this, girls had higher levels of GSSG (p < 0.001) and TG (p = 0.001), and a lower GSH/GSSG ratio (p < 0.001) than boys. For the antioxidant response, girls had higher levels of SOD (p = 0.002) than boys. All analyses were adjusted for BMI, age, fitness, and physical activity. In conclusion, prepubertal girls had higher oxidative stress than boys, in addition to higher levels of SOD, independent of age, BMI, fitness, and physical activity.

To assess the impact of fitness status and physical activity on oxidative stress in prepubertal children, we measured selected biomarkers such as protein carbonyls (PC), lipid peroxidation products, and total nitrites, as well as the antioxidant system: total glutathione (TG), oxidized glutathione (GSSG), reduced glutathione (GSH), superoxide dismutase activity, and glutathione peroxidase. A total of 132 healthy children ages 7–12, at prepubertal stage, were classified into two groups according to their fitness level: low fitness (LF) and high fitness (HF). They were observed while engaged in an after-school exercise program, and a questionnaire was created to obtain information on their physical activity or sedentary habits. Plasma and red blood cells were obtained to analyze biomarkers. Regarding oxidative stress markers, the LF group and the sedentary group showed higher levels of TG and GSSG and a lower GSH/GSSG ratio than the HF group and the children engaged in physical activity. A negative association was found between PC and GSSG and TG and between TG and the GSH/GSSG ratio. Moreover, a negative correlation was found between GSSG and fitness, with a positive correlation with the GSH/GSSG ratio. TG, GSSG, and the GSH/GSSG ratio seem to be reliable markers of oxidative stress in healthy prepubertal children with low fitness or sedentary habits. This research contributes to the recognition that an adequate level of fitness and recreational physical activity in childhood leads to better health and oxidative status.

ObjectiveTo assess classical and non-classical metabolic risk biomarkers in prepubertal children with different levels of cardiorespiratory fitness (CRF).DesignCRF was assessed by the 20 m shuttle run test. To estimate physical activity, participants were observed while engaged in an after-school programme. Additionally, a short test based on a validated questionnaire was used to obtain information about physical activity practice and sedentary habits. Anthropometric parameters, blood pressure, and classical and non-traditional metabolic risk biomarkers – plasma lipid profile, glucose and insulin, homeostasis model assessment–insulin resistance index (HOMA-IR), plasma uric acid, transaminases and C-reactive protein (CRP) – were measured.SettingThe study was conducted in local elementary schools in Córdoba, Spain.SubjectsOne hundred and forty-one healthy children (eighty-eight boys, fifty-three girls) aged 7–12 years, in Tanner stage I, were recruited. They were divided into two groups after they performed the 20 m shuttle run test: equal or higher cardiovascular fitness (EHCF) group and low cardiovascular fitness (LCF) group.ResultsThe LCF group displayed significantly higher TAG (P = 0·004) and lower HDL cholesterol levels (P = 0·001), as well as significantly lower values for the non-traditional lipid marker apo-A1 (P = 0·001) compared with the EHCF group. The LCF children displayed higher plasma glucose (P = 0·003) and insulin levels, higher HOMA-IR scores (P < 0·001) and higher plasma uric acid and CRP levels (P < 0·05). After adjustment for BMI, age and sex, no statistically significant differences were found between groups for the biomarkers analysed.ConclusionsThe study provides new information to understand the role not only of weight status but also of the level of CRF on the metabolic health profile of prepubertal children.

ResumenEl ejercicio físico puede producir estrés oxidativo en el individuo lo que pueden condicionar el riesgo cardiovascular en niños y adolescentes. Este estudio pretende analizar el estrés oxidativo según la fuerza muscular isométrica de las extremidades superiores en la edad pediátrica. Se estudiaron 70 niños sanos con edades entre 10 y 14 años, y se analizaron en saliva los lipoperóxidos (LPO), el glutatión reducido (GSH), la ratio GSH/LPO y la catalasa, como marcadores de estrés oxidativo. La muestra se dividió en dos grupos según una condición física superior o inferior medida a través de dinamometría manual (TKK 5110); se diferenció la serie en sujetos prepuberales y puberales. Se encontraron niveles significativamente inferiores de GSH y GSH/LPO en el grupo de niños con fuerza superior, y en los puberales con la mismas características; estos resultados podrían indicar la existencia de un mayor estrés oxidativo en esta situación. En conclusión, los mayores niveles de fuerza músculo esquelética, medida a través de dinamometría manual, posiblemente pueden estar asociados a un mayor estrés oxidativo en niños púberes con condición física musculoesquelética superior.AbstractPhysical exercise can produce oxidative stress, this situation could contribute cardiovascular risk in children and adolescents. The following study tries to evaluate the oxidative stress produced according to the handgrip strength in infancy. 70 healthy male subjects, ages 10 to 14 years, were studied. In the saliva samples, lipoperoxides (LPO), reduced glutathione (GSH), glutathione/lipoperoxides ratio and catalase were analyzed as biomarkers of oxidative stress. Children were divided into two groups according to their handgrip strength (high or low) measured by handgrip strength (TKK 5110). The groups were also divided into prepubertal and pubertal subjects. We found GSH’s significantly low levels and of GSH/LPO in pubertal group with high handgrip strength. We could possibly conclude that the higher levels of handgrip strength could be associated with more oxidative stress in pubertal group with high fitness.doi:10.5232/ricyde2011.0220

Evaluate the influence of puberty in oxidative stress. The study included 38 prepubescent males with Tanner G(1)-P(1) and 32 healthy pubescent boys with Tanner G(3-4)-P(3-4). Weight, height and body mass index, heart rate, blood pressure values were within the 50 percentile 50+/-1SD for their age. The biomarkers were measured in saliva, as a good correlation between saliva and plasma levels has been reported in lipoperoxidation products, reduced glutathione and catalase. Pubescent boys had significantly higher levels of lipoperoxidation products (P<0.001) compared with the prepubertal group, with no significant differences in the other parameters measured. There was a significant positive correlation between lipoperoxides and reduced glutathione in these children. It is the first time that an increase of lipoperoxidation products has been reported in pubertal boys and this biomarker could play a role in the development of oxidative stress in this stage of life.

Intense aerobic exercise has been found to prompt changes in oxidative stress, but in children remains almost unexplored. The aim was to investigate the effect of intense physical exercise on reduced glutathione (GSH as a biomarker of oxidative stress) and adrenocortical response (to verify a certain level of stress after exercise) in 38 prepubescent and 32 pubescent non-athlete boys. Four subgroups were established as puberty stage and physical fitness. Saliva samples were taken before and after incremental exercise testing to measure GSH, and cortisol levels. Saliva reduced glutathione levels were lower in all subgroups after exercise except in the prepubescent average fit group, significance being greater in the pubescent (P P < 0.01). Saliva cortisol increased after exercise in all except in the prepubescent “average fit” group. Physical exercise may give rise to oxidative stress and adrenocortical response in pubescent and prepubescent boys, depending on the duration and intensity of the test.
