ABSTRACT
The aim of this study was to compare the effects of exercise intensity on appetite control: relative energy intake (energy intake minus the energy expenditure of exercise; REI), hunger scores, and appetite-regulating hormones in men and women. Eleven men and 9 women were submitted to 4 experimental sessions: high-intensity intermittent all-out exercise (HIIE-A) for 60 × 8 s interspersed by 12 s of passive recovery; high-intensity intermittent exercise (HIIE) at 100% of maximal load attained in incremental test; steady-state exercise at 60% of maximal load, matched by work done; and a control session. Exercise was performed 1.5 h after a standardized breakfast, and an ad libitum lunch was offered 4 h after breakfast. Blood concentration of insulin, cortisol, acylated ghrelin, peptideYY3-36, glucose, and hunger scores were measured when fasting, and at 1.5, 2, 3.25, and 4 h of experiment. REI was lower in all exercises than in the control, without differences between exercises and sex showing no compensation in energy intake because of any exercise; the hunger scores were lower only in the exercises performed at higher intensity (HIIE and HIIE-A) compared with the control. The area under the curve of acylated ghrelin was lower in the HIIE-A when compared with the control. PeptideYY3-36 was higher in men than women and cortisol higher in women than men independently of the condition. Although high-intensity exercises promoted a little more pronounced effects in the direction of suppressing the appetite, no differences were observed in REI, demonstrating that these modifications were not sufficient to affect energy intake.
ABSTRACT
O objetivo do presente estudo é analisar a associação entre as recomendações recebidas durante o atendimento pré-natal com a prática de atividade física na gestação. Trata-se de um estudo transversal com 290 puérperas. Apenas 9% das mulheres atingiam a recomendação (≥150 minutos) de atividade física semanal para manutenção da saúde e 18% praticaram alguma atividade física no lazer (AFL)/exercício físico na gestação. A prática de atividade física anterior à gestação estava associada ao nível de AFL. Adicionalmente, a percepção da presença de recomendação do profissional para a prática de AFL no pré-natal triplicou a chance da mulher ser ativa, ainda que não suficientemente ativa. Ações junto aos profissionais de saúde podem promover modificações no nível de AFL durante a gestação.
The aim of this study is to analyze the association between the recommendations received during the prenatal care with the practice of physical activity during pregnancy. This is a cross-sectional study of 290 postpartum women. Only 9% of women reached the recommendation (≥150 minutes) of weekly physical activity for health maintenance and 18% practiced some physical activity in leisure (LPA) / exercise during pregnancy. The practice of previous physical activity before pregnancy was associated with LPA level. In addition, the perception of professional recommendation of presence to the practice of LPA in the prenatal tripled the chance of women being active, although not sufficiently active. Actions with health professionals can promote changes in LPA level during pregnancy.
El objetivo es analizar la asociación entre las recomendaciones durante la atención prenatal y la práctica de la actividad física durante el embarazo. Este estudio transversal con 290 mujeres en el posparto. Sólo 9% de las mujeres llegó a la recomendación (≥150 minutos) de actividad física semanal para mantener la salud y el 18% practico alguna actividad física en el tiempo libre (LPA)/ejercicio durante el embarazo. La práctica de actividad física previa antes del embarazo se asoció con la LPA. Además, la percepción de la recomendación profesional para LPA en el prenatal se triplicó la probabilidad de que las mujeres ser activa, aunque no suficientemente activa. Acciones con profesionales de la salud pueden promover cambios en el nivel LPA durante el embarazo.

Avaliar as modificações na prática de atividade física (AF) e as barreiras para adoção de um estilo de vida saudável em mulheres que receberam orientações nutricionais e de AF durante a gestação e no primeiro ano após o parto. MÉTODOS: estudo de coorte com 57 mulheres (Grupo Controle = 29 e Grupo Intervenção = 28), e idade média igual a 28 (±6) anos. As informações foram obtidas através de entrevistas em visita domiciliar (durante a intervenção) e inquérito telefônico (um ano após o término da intervenção), utilizou-se questionário de AF. Para análise das barreiras foi realizada uma entrevista semiestruturada com questões abertas, as quais foram codificadas e agrupadas para análise dos dados. Foram realizados testes de qui-quadrado, Mann-Whitney U e Friedman. RESULTADOS: aos seis meses, apenas 30 por cento das mulheres do grupo Intervenção realizavam AF no lazer pelo menos 120 minutos por semana, contra 10 por cento do grupo Controle, reduzindo para 18 por cento e 4 por cento, respectivamente, dois anos após o parto. As principais barreiras à prática de AF regular foram: falta de tempo (44 por cento), cuidado com os filhos (37 por cento), trabalho (21 por cento), afazeres domésticos (21 por cento) e comodismo (26 por cento). CONCLUSÕES: futuros programas devem priorizar a aquisição de conhecimento, visando à adoção de um estilo de vida ativo no pós-parto, considerando as barreiras maternas...
To evaluate changes in the practice of physical activity (PA) and the barriers to adopting a healthy lifestyle among women who have received guidance on nutrition and PA during pregnancy and in the first year after giving birth. METHODS: cohort study with 57 women (Control Group = 29 and Intervention Group = 28), and mean age 28 (±6) years. The information was obtained through home visit interviews (during intervention) and telephone interviews (one year after the end of intervention), using the PA questionnaire. To analyze the barriers a semi-structured interview with open questions was carried out, these being codified and grouped for data analysis. Chi-square, Mann-Whitney U and Friedman tests were carried out. RESULTS: at six months, only 30 percent of the women in the Intervention Group were practicing leisure-time PA at least 120 minutes per week, as opposed to 10 percent from the Control Group, decreasing to 18 percent and 4 percent respectively two years after giving birth. The principal barriers to practicing PA regularly were: lack of time (44 percent), taking care of children (37 percent), work (21 percent), domestic chores (21 percent) and laziness (26 percent). CONCLUSIONS: future programs should prioritize the acquisition of knowledge, with a view to adopting an active lifestyle after giving birth, considering the maternal barriers...
