Association Between Maternal Physical Activity, Gestational Weight Gain And Birth Weight In A Cohort Of 118 Pregnant Women In Campina Grande, Northeast Of Brazil [associação Entre O Padrão De Atividade Física Materna, Ganho Ponderal Gestacional E Peso Ao Nascer Em Uma Coorte De 118 Gestantes No Município De Campina Grande, Nordeste Do Brasil]

Objective: This survey evaluated the effects of physical activity on gestational weight gain and birth weight of pregnant women attended by the Family Health Program in Campina Grande, Northeast of Brazil. Methods: A cohort study enrolling 118 pregnant women was conducted between 2005 and 2006. Evaluation of the initial nutritional status was performed following Atalah's criteria and gestational weight gain was evaluated according to the Institute of Medicine. The pattern of physical activity was evaluated according to METs (metabolic equivalent) and its association with weight gain and birth weight was determined. Results: The predominant physical activity pattern at 16 weeks was mild, in 85.6% of pregnant women. An important reduction of physical activity levels was observed with evolution of pregnancy and 98.3% of pregnant women were sedentary at 24 weeks and 100% at 32 weeks. In the initial evaluation of nutritional status 50% were normal, 23% had low weight and 27% had overweight/obesity. At second and third trimesters about 45% of pregnant women had excessive weight gain. Adequate birth weight for gestational age was found in 85.6% of neonates but macrosomia was highly frequent (8.5%). A significant association between METs at 24 weeks and gestational weight gain was found in the second trimester (p=0.045). cOnclusiOn: All the pregnant women were sedentary in the third trimester and a significant association between physical activity pattern and gestational weight gain was found in the second trimester, but there was no association between this pattern and birth weight.553335341Caspersen, C.J., Kriska, A.M., Dearwater, S.R., Physical activity epidemiology as applied to elderly populations (1994) Baillieres Clin Rheumatol, 8, pp. 7-27(2002) The optimal duration of exclusive breast-feeding a systematic review, , World Health Organization (WHO), Geneva: World Health organizationClapp, J.F., Kim, H., Burciu, B., Lopez, B., Beginning regular exercise in early pregnancy: Effect on fetoplacental growth (2000) Am J obstet Gynecol, 183, pp. 1484-8Exercise during pregnancy and the postpartum period (1994) Washington (DC): ACoG Technical Bulletin, p. 189. , ACOG.

Effects Of Long-term Creatine Monohydrate Supplementation On Anaerobic Performance Of Trained Young Adults [efeitos Da Suplementação Prolongada De Creatina Mono-hidratada Sobre O Desempenho Anaeróbio De Adultos Jovens Treinados]

The objective of the present study was to investigate the impact of eight weeks of creatine monohydrate (Crm) supplementation on the anaerobic performance of young trained adults. Twenty-six healthy male physical education students were randomly divided in creatine group (CrG, n = 13; 22.5 ± 2.7 years; 74.9 ± 6.8 kg; 178.5 ± 4.8 cm) and placebo group (PlG, n = 13; 22.9 ± 3.2 years; 71.9 ± 11.3 kg; 178.6 ± 4.0 cm). The subjects received in a double-blind system a Crm or placebo-maltodextrin dose (20 g.d-1 for 5 days and 3 g.d-1 for 51 subsequent days). Both groups had their eating habits and levels of physical fitness previously controlled. The Wingate anaerobic test (WT) was used to evaluate the anaerobic performance before and after the ingestion period of Crm or placebo. The performance indexes assessed were: relative peak power (RPP), relative mean power (RMP), relative total work (RTW) and index of fatigue (IF). ANOVA followed by Tukey post hoc test were used when P<0.05 for statistical treatment. No significant difference in RPP, RMP, RTW or IF was observed after the period of supplementation of Crm (P>0.05). The results of the present study suggest that Crm supplementation does not seem to be an efficient ergogenic resource in high-intensity and short-duration efforts involving a single set.163186190Mesa, J.L., Ruiz, J.R., Gonzalez-Gross, M.M., Gutierrez-Sainz, A., Garzon, M.J.C., Oral creatine supplementation and skeletal muscle metabolism in physical exercise (2002) Sports Med, 32, pp. 903-944Branch, J.D., Effect of creatine supplementation on body composition and performance: A meta-analysis (2003) Int J Sport Nutr Exerc Metab, 13, pp. 198-226Persky, A.M., Rawson, E.S., Safety of creatine supplementation (2007) Subcell Biochem, 46, pp. 275-289Brudnak, M.A., Creatine: Are the benefits worth the risk?
