NIVEL DE CONDICIÓN FÍSICA Y SU RELACIÓN CON EL ESTATUS DE PESO CORPORAL EN ESCOLARES

OBJECTIVE To explore and establish possible relationships between body weight status and fitness level in a sample of primary school children. METHODS Descriptive and cross-sectional study. A total of 216 students (125 women 8-11 years) participated in the assessment of weight, height and physical condition. The body weight status (normal-weight, overweight and obesity) was categorized according to international standards. RESULTS males have on average higher values in the running test 4x10 meters, manual dynamometry, longitudinal jump and Course-Navette. Women show a higher tendency to exceed healthy weight. The analysis showed that a high level of fitness is directly associated with normal weight status (p <.01). CONCLUSIONS The results of this study suggest that students who have higher fitness levels are more likely to have a body weight status within normal parameters. Programs promoting physical activity, aimed to improve fitness, and thus the body status need to be implemented. Increasing physical education time at school or conducting educational programs focused on nutrition can be effective measures to improve overall health.

Relación entre el estatus de peso corporal y el autoconcepto en escolares

Body weight status has been linked to other health parameters. The aim of this study was to evaluate the relationship between body weight status and self-concept in a sample of 216 students (9.26 ± 1.26 years) from schools of the Southeast of Spain. BMI (Body-mass index) was used to evaluate the body weight status. Subjects were classified into normal weight, overweight and obesity according to international standards. The six dimensions of self-concept (intellectual, behavioral, physical, lack of anxiety, social and life satisfaction) were assessed using the Piers-Harris Self-Concept Scale. The results showed significant associations between BMI and intellectual self-concept, life satisfaction, global self-concept and physical self. Subjects categorized as overweight or obese were those who showed lower scores on the self-concept scale. Interventions focused on improving the body weight status are needed in order to achieve better self-concept levels and health among young people.

Estado nutricional y calidad de vida relacionada con la salud en escolares del sureste español

INTRODUCTION AND OBJECTIVE Analyze the level of Life Quality (LQ) in relation to nutritional status in a sample of primary school children. MATERIAL AND METHODS Cross sectional study with 298 participants (53.35% female) of 8-12 years. LQ was assessed by the KIDSCREEN-10 questionnaire . Measures of weight and size were taken. The BMI (normal-weight, overweight and obesity) was categorized using standard criteria. To establish the relationship between the different statistical variables was performed the Kolmogorov- Smirnov test and analysis of variance. RESULTS Nutritional status was significantly correlated with LQ (F = 5.096; p =, 007). School children with a normal- weight state showed higher LQ levels compared to those overweight (p = .015) and obese (p =, 013). CONCLUSIONS The results show that nutritional status acts as a differentiating factor in LQ. Adopting active lifestyle behaviours that promote a healthy nutritional status not only can have benefits over health biological parameters (such as physical condition) but can also contribute to improve other LQ indicators and mental health .

Capacidad aeróbica y calidad de vida en escolares de 8 a 12 años

Aerobic capacity is a powerful physiological indicator of the overall health status. The objective of this study was to analyse the relationship between aerobic capacity and quality of life in a sample of 298 (159 girls) school children aged 8-12 years. Aerobic capacity was tested using the Course-Navette test. Quality of life was assessed using the KIDSCREEN-10 Index scale. Males showed higher performance in the Course-Navette test and highest values of VO2max (P<.001 for both). ANOVA statistical analysis showed that the quality of life was significantly higher in school children with increased level of aerobic capacity compared to those with a low level (P=.001). Children with high aerobic capacity showed higher quality of life scores in relation to their peers with low scores (P<.001). As for the females, significant differences were found among those with high aerobic capacity level and their peers low levels (P<.031). The results of this study suggest that school children with higher level of aerobic capacity show better results in the quality of life index. Long-term intervention studies are needed to verify if an aerobic capacity development programme may upgrade the quality of life of children and adolescents.

Influencia de un programa de ejercicio físico terapéutico sobre el consumo máximo de oxígeno en adultos con factores de riesgo cardiovascular

OBJECTIVE The aim of the study was to assess the influence of a physical exercise program on VO2max in sedentary subjects with cardiovascular risk factors. MATERIALS AND METHODS The sample was composed of 214 patients (80 males, 134 females) with an average age of 52 years, who were referred to a physical exercise program from 2 primary care centres of Spanish southeast. It was implemented a 10 week program (3 training×1h/week) combining strength with cardiorespiratory fitness. TheVO2max was analyzed through the Rockport Walk Test (RWT) comparing the pre and post program measurements. RESULTS The results show significant improvements on VO2max for both genders (p<0,05). The most pronounced increase in VO2max was among males in the highest age band (56-73 years). CONCLUSIONS Prescribing and referral exercise programs from primary care centers must be considered as a resource for improving cardiorespiratory fitness in the population studied.

Capacidad aeróbica, estado de peso y autoconcepto en escolares de primaria

OBJETIVES To analyze the relationship between self-concept, aerobic capacity and weight status in schoolchildren. MATERIAL AND METHOD Relational descriptive design in which was assessed the weight status and aerobic capacity of 256 schoolchildren among 8-11 years. Aerobic capacity (low vs high) and the body mass index (normal-weight vs overweight-obesity) were categorized using standard criteria. The self-concept was assessed through the Piers Harris self-concept scale for children. RESULTS Schoolchildren with normal-weight and high fitness level showed better levels of conductual self-concept (P=.030), physical (P<.001), lack of anxiety (P=.048), and global self-concept (P=.002). The schoolchildren with normal-weight show higher levels of conductual self-concpt (P=.016), intellectual (P=.050), physical (P<.001), life satisfaction (P=.036), and global self-concept (P=.001). The schoolchildren with a higher fitness level showed better conductual self-concept (P=.024), physical (P=.004), lack of anxiety (P=.011), social (P=.024), and global (P=.003). CONCLUSIONS The results of the study strengthen the importance to transmit to the educative community the knowledge of the relationship between the variables analyzed aiming to improve the schoolchildren self-concept.

The relationship between segmental coordination, agility and physical activity in adolescents

A competencia motora (CM) pode estar relacionada com o nivel de atividade fisica (PA) dos jovens. Nos ultimos anos, a CM infantil tem sido estudada como possivel determinante do nivel de AF, mas ainda nao foi extensivamente estudada em adolescentes. Para analisar a relacao entre o nivel de AF e competencia motora foram avaliados 533 adolescentes (271 homens e 261 mulheres), no sudeste de Espanha. Para registar a AF semanal empregou-se o Questionario Internacional de Atividade Fisica (IPAQ), e para a CM quatro testes de coordenacao, incluindo lancamento e recepcao, coordenacao oculo manual e oculo pedal e um percurso de agilidade. Os dados foram analisados usando a analise de variância e a analise de regressao logistica binaria. A competencia global motora revelou-se consistentemente relacionada com o nivel de AF. O teste de coordenacao olho-mao e o teste de agilidade sao os que definem mais precisamente uma tendencia regular de alto nivel de atividade fisica. Programas voltados para aumentar a coordenacao segmentar e agilidade devem ser incentivados desde tenra idade nas escolas.

Relationship between the Self-Concept and Muscular Strength in Southern Spanish Children

Objetive: The purpose of this study was to analyze the relationship between self-concept and muscular strength in elementary schoolchildren. Design: Ex post facto cross-sectional design and descriptive court. Method: 256 schoolchildren (142 females) aged 8 to 11 participated in the handgrip strength and longitudinal jump assessment to calculate the muscular strength index. Self-concept was assessed by the Self-Concept Scale Piers-Harris. Results: In both genres, higher muscular strength levels were significantly associated with the behavioral (p=0,002), physical (p<0,001), lack of anxiety (p=0,022) and social self-concept dimensions. A positive correlation (p=0,004) was found between muscular strength and global self-concept, showing significant differences in favor of males in all the dimensions analyzed and the global self-concept. Conclusion: The results of this study suggest that muscular strength is a distinctive element in the schoolchildren self-concept. Further longitudinal studies are needed to analyze the complex relationship between self-concept and physical fitness, considering the results emerged from this study.
