Objective: To analyze the compliance to antiretroviral therapy among HIV/AIDS patients. Method: 99 HIV-positive volunteers undergoing treatment responded to a semi-structured sociodemographic interview and to a questionnaire that assessed compliance to antiretroviral treatment. Results: In the sample analyzed, 52.5% of the volunteers presented good/adequate treatment compliance, while 33.3% presented low/insufficient compliance. There was no significant difference between men and women in the questionnaire score, nor between groups with different levels of education. Conclusion: The main items of the questionnaire that contributed to good/adequate compliance were: positive impact of treatment on health and quality of life, few side effects after initiation of therapy, and positive self-evaluation of participants regarding their compliance to antiretroviral therapy. The main barriers detected for compliance to antiretroviral therapy were the lack of knowledge about current medications and the lack of information on antiretroviral therapy drugs.

PurposeThe aim of this study was to investigate the effect of self-paced active recovery (AR) and passive recovery (PR) on blood lactate removal following a 200 m freestyle swimming trial.Patients and methodsFourteen young swimmers (with a training frequency of 6–8 sessions per week) performed two maximal 200 m freestyle trials followed by 15 minutes of different recovery methods, on separate days. Recovery was performed with 15 minutes of passive rest or 5 minutes of passive rest and 10 minutes of self-paced AR. Performance variables (trial velocity and time), recovery variables (distance covered and AR velocity), and physiological variables (blood lactate production, blood lactate removal, and removal velocity) were assessed and compared.ResultsThere was no difference between trial times in both conditions (PR: 125.86±7.92 s; AR: 125.71±8.21 s; p=0.752). AR velocity was 69.10±3.02% of 200 m freestyle trial velocity in AR. Blood lactate production was not different between conditions (PR: 8.82±2.47 mmol L−1; AR: 7.85±2.05 mmol L−1; p=0.069). However, blood lactate removal was higher in AR (PR: 1.76±1.70 mmol L−1; AR: 4.30±1.74 mmol L−1; p<0.001). The velocity of blood lactate removal was significantly higher in AR (PR: 0.18±0.17 mmol L−1 min−1; AR: 0.43±0.17 mmol L−1 min−1; p<0.001).ConclusionSelf-paced AR shows a higher velocity of blood lactate removal than PR. These data suggest that athletes may be able to choose the best recovery intensity themselves.

The aim of this study was to analyze the acute metabolic response to exercise in fasting and postprandial. For this, ten individuals were submitted to an incremental treadmill test, with an initial speed of 5 and 1 km/h increments every minute, with no inclination, and a body composition assessment. After this 1st day, all volunteers were submitted to two experimental procedures (fasting and postprandial), with an aerobic exercise performed for 36 minutes at 65% of maximal oxygen consumption. At postprandial procedure, all subjects ingested a breakfast containing 59.3 g of carbohydrate (76.73%), 9.97 g of protein (12.90%), 8.01 g of lipids (10.37%), with a total energy intake of 349.17 kcal. An analysis of plasma concentration of triglycerides, lactate, and glucose was performed in two stages: before and after exercise. The Shapiro–Wilk test was used to verify the normality of the data. For analysis of glucose concentration, plasma lactate, and triglycerides, we used a repeated measures analysis of variance factorial 2×2, with Bonferroni multiple comparison test. The significance level of P<0.05 was adopted. The results indicated a maintenance level of glucose at fasting and a decrease in glucose concentration at postprandial exercise. Both conditions increase plasma lactate. Triglycerides also increased in the two experimental conditions; however, after exercise fasting, the increase was significantly higher than in the postprandial exercise. These data suggest that both exercises could increase plasma lactate and triglycerides. However, exercise performed in fasting condition decreases glucose concentration and increases triglycerides, even more than postprandial exercise.

A educação física escolar como agente da prevenção e do tratamento do sobrepeso e obesidade infantil* The physical education as agent of prevention and tratment from childhood obesity and overweight ResumoEste estudo analisou se as aulas contribuem para prevenção da obesidade infantil e o Índice de Massa Corporal (IMC) dos alunos. A amostra foi constituída por 44 crianças e um professor. Verificou-se o IMC para classificação da obesidade e aplicado um questionário para o professor para avaliar o conhecimento do mesmo sobre o assunto obesidade. Foram observadas aulas para verificar se este executava alguma ação para tratar o quadro de obesidade de seus alunos. 65,9% das crianças foram classificadas como eutróficas, enquanto 34,1% apresentavam sobrepeso ou obesidade. Não houve diferença entre meninos e meninas na massa corporal (p = 0,523), na estatura (p = 0,352) e no IMC (p = 0,897). O professor avaliado abordou que a intervenção feita por ele é, apenas, uma conscientização dos males causados pela obesidade. As intervenções realizadas pelo professor nas aulas não eram efetivas para combate ou prevenção da obesidade, devido à falta de aulas disponíveis para um trabalho dessa proporção. Palavras-chave: Sobrepeso. Obesidade Infantil. Educação Física Escolar. AbstractThis study examined if the teacher made some intervention on the class to prevent childhood obesity. The sample was built by 44 children and one teacher. Was measured the BMI, to rating the children of obesity and applied a questionnaire to the teacher to assess his knowledge about the subject obesity. Were observed classes to verify if the teacher performs some activity to deal with the status of obesity of students. 65.9% from the children were eutrophic, while 34.1% were overweight or obesity. Did not has difference between boys and girls in body mass (p= 0.523), in height (p= 0.352) and BMI (p= 0.897). The teacher evaluated addressed that the intervention made by him, it is only an awareness about the illnesses, caused by obesity. The interventions made by the teacher in the classes were not effective in fighting against overweight and obesity, due a lack of classes available to a program with this proportion.
