Breast cancer survivors have changes in their body composition and in handgrip strength six months after surgery; however, the interaction between the type of surgery and its impact is unclear. Furthermore, women who developed lymphedema in this period showed more significant changes in the body composition, but they were not enough to cause impairment in handgrip strength.

OBJECTIVE To analyze the effects of a 20-week concurrent training on the variables of body composition, lipid profile, and fatty liver diagnosis in obese adolescents. METHODS An open clinical trial was carried out with 34 obese adolescents aged between 12 and 15 years. Total body fat, trunk fat mass, total cholesterol and its fractions (HDL, LDL and VLDL), and triglycerides were analyzed; an upper abdominal ultrasound was performed in order to diagnose fatty liver. The participants underwent concurrent training (association of weight training with aerobic training) three times per week, lasting one hour for 20 weeks. Statistical analysis included paired Studentâ€(tm)s t-test and frequency analysis in order to verify the relative and absolute reductions of fatty liver diagnosis, being significant p<0.05. RESULTS The studied adolescents showed statistically significant improvement in body composition, with a decrease of total body fat percentage, total fat mass, trunk fat, and an a increase in the lean body mass. They also presented reduced size of liver lobes, decrease in total cholesterol and in LDL-cholesterol, with a lower prevalence of fatty liver. CONCLUSIONS The concurrent training was effective for promoting significant improvements in body fat composition and lipid profile variables, besides reducing fatty liver prevalence rate.

Resumo -A monitoração dos níveis de prática de atividade física em segmentos da população jovem tem se tornado importante tema de interesse entre especialistas da área. O Objetivo do estudo foi verificar o nível de atividade física de escolares, baseando-se em duas recomendações vigentes, e analisar a existência de associações entre a quantidade de passos/dia e diferentes indicadores de adiposidade corporal. A casuística foi composta por 162 indivíduos de dez a 18 anos (65 do sexo masculino e 97 do sexo feminino NL-2000) based on the following recommendations: Duncan et al. (male: 16,000 steps/day and female: 13,000 steps/day) and 000 steps/day and female: 12,000 steps/day Abstract -Monitoring physical activity levels in segments of the young population has become an important topic among specialists. The objective of this study was to analyze the physical activity level of schoolchildren based on two current recommendations and to examine the association between the number of steps/day and different indicators of adiposity. The sample consisted of 162 subjects aged 10 to 18 years (65 boys and 97 girls). Body mass index and body fat percentage were calculated. The level of physical activity was quantified with a pedometer (New Lifestyles
