In humans, psychic and motor skills are interdependent, and therefore, cannot fail to take into account the influence of a good psychomotor development in the prevention of learning difficulties. Another factor that interferes with the learning process is the social. Family problems, socioeconomic status of the child, among others, may be associated with learning difficulties and, consequently, the student's performance. Therefore, the aim of this study was to investigate through the elements of psychomotor, if a delay in neuropsychomotor development may be related to the presence of learning problems in children entering elementary school. Also, determine whether there were differences regarding the presence or absence of these difficulties in students from middle and low social class and have family problems or not. For this, we analyzed two classes of 49 students from 1 year of elementary education at a public school in the city of Bauru/SP, aged between 6 and 7 years. These students were tested for the ENE proposed by Lefèvre (1976) to assess the maturity of the nervous system. A pre-designed questionnaire was answered by the teachers of classes to know students' academic performance, learning difficulties presented by them, social status and the presence of family problems. All students participating in the survey had the term sheet signed by the parents, allowing participation in the study. To reach the results, we applied the Anova and Tukey test for comparison analysis of mean age in the performance of ENE. To investigate the existence of a relationship between performance in the ENE and learning difficulties, we used the calculation of Pearson correlation. To analyze the difference in average scores of learning disabilities in students from different social classes and among those who had family problems or not, comparative graphs were used with the averages obtained from the questionnaire answered by the teachers for each learning...

INTRODUÇÃO: Um dos benefícios promovidos pelo exercício físico parece ser a melhora da modulação do sistema nervoso autônomo sobre o coração. No entanto, o papel da atividade física como um fator determinante da variabilidade da frequência cardíaca (VFC) não está bem estabelecido. Desta forma, o objetivo do estudo foi verificar se há correlação entre a frequência cardíaca de repouso e a carga máxima atingida no teste de esforço físico com os índices de VFC em homens idosos. MÉTODOS: Foram estudados 18 homens idosos com idades entre 60 e 70 anos. Foram feitas as seguintes avaliações: a) teste de esforço máximo em cicloergômetro utilizando-se o protocolo de Balke para avaliação da capacidade aeróbia; b) registro da frequência cardíaca (FC) e dos intervalos R-R durante 15 minutos na condição de repouso em decúbito dorsal. Após a coleta, os dados foram analisados no domínio do tempo, calculando-se o índice RMSSD, e no domínio da frequência, calculando-se os índices de baixa frequência (BF), alta frequência (AF) e razão BF/AF. Para verificar se existe associação entre a carga máxima atingida no teste de esforço e os índices de VFC foi aplicado o teste de correlação de Pearson (p < 0,05). RESULTADOS: Características demográficas, antropométricas, fisiológicas e carga máxima atingida no teste ergométrico: idade = 63 ± 3,0 anos; IMC = 24 ± 2kg/m²; FC = 63 ± 9bpm; PAS = 123 ± 19mmHg; PAD = 83 ± 8mmHg; carga máxima = 152 ± 29 watts. Não houve correlação entre os índices de VFC com os valores de FC de repouso e carga máxima atingida no teste ergométrico (p > 0,05). CONCLUSÃO: Os índices de variabilidade da frequência cardíaca temporal e espectrais estudados não são indicadores do nível de capacidade aeróbia de homens idosos avaliados em cicloergômetro.

The development of populations of gastrointestinal parasites resistant to antihelmintics has led to seeks new alternatives its control. Stimulation of natural immunity by means of animal nutrition has shown promising results in controlling nematodes in sheep. The addition of protected fat sources, containing essential fatty acids, may be an alternative due to many effects, among them, regulation of immunity expression and regulation of the inflammatory response by immune effectors. The aim of this study was to estimate correlations between haematological and parasitological patterns, animal performance through weight and body condition, under the influence of protected fat in ewes. Fifty Santa Ines sheep, in the final third of pregnancy or postpartum, in paddocks of Panicum maximum, received, individually, 200 g per day of concentrate, isonitrogenous and isocaloric diets, with or without the addition of protected fat. In general, except for total leukocytes and eosinophils, almost all of Pearson correlation coefficients of other variables were significant. However, the protected fat, in the amount offered, had no antihelmintic effect.

This study aimed to investigate the relation between physical activity levels (PAL) of hypertensive patients, seeing different do- mains, and, to compare anthropometric variables and blood pressure (BP). The survey was conducted with 192 patients, mean age 63 ± 11 years. The anthropometric variables were body weight, body mass index (BMI) and waist circumference (WC). PAL was estimated using Baecke ́s questionnaire and categorized in four domains (OPA = occupational; leisure time = LTPA; locomotion = LPA and Total PA). Student t test unpaired was applied for comparisons between active and insufficiently active. Differences between active and sedentary in relation to anthropometry and resting blood pressure were observed for the LTPA, LPA and Total PA and significant negative correlations were observed between LPA and Total PA with systolic BP (p<0,05). Conclusion: the LPA and LTPA were associated with resting BP in hypertensive. No differences in BMI and WC among physically active and insuffi- ciently active were found.

The actual study goal is to test the Ellestad and Weltman protocol concordance in the prediction of VO2max in Futsal athletes. There was no significant difference between the two protocols, there was significant correlation between methods, but the Bland & Altman plotting shown very high amplitude in the Confident Interval at 95%.
