To verify the glycemic safety of a maximal cardiorespiratory test (V?O2max) in T1D and correlate the maximum oxygen uptake values obtained with metabolic control parameters such as glycaemia, glycated hemoglobin, time of diagnosis (TD) and fat (body [GC] and visceral [GV]). The cross-sectional study evaluated 10 T1DM (3 women) (age 24.9 ± 7.5 years; time of diagnosis 11.5 ± 7.4; body mass index 22 ± 2 kg/m2). Metabolic glycemic control variables (before and after), glycated hemoglobin (HbA1c), time since diagnosis and total and visceral fat were collected. The CENESP maximum test protocol was used on the treadmill with direct maximal oxygen uptake (V?O2max). Normality test, paired t-test and correlations (p

Introduction: During the aging process, significant changes in the pattern of distribution of morphological and structural variables such as body fat and muscle mass can be observed. Objective: To analyze the distribution of total and appendicular muscle mass in women in different age groups. Methods: The sample consisted of 129 women, aged between 50 and 80 years. The study was divided into two stages, composed of the anthropometric measures, total body mass (kg) and height (m) and body composition evaluation using DEXA. Results: There was a significant reduction in muscle mass with the advancement of age, and from age 60 and older, the age group showed a significant increase when compared to subjects of lower age, with a decrease of 1.65 kg in their total muscle mass. It should be noted that in our study, this progression increased in subjects older than 72 years, with a decrease of 2,10 kg in their total muscle mass. Conclusions: The reductions of muscle mass in the lower limbs presented greater amplitudes in comparison with the other regions of the analyzed human body, being an area with greater focus of analyzes with the objective of identifying and assisting the diagnosis of sarcopenia in future studies.

Introdução: O consumo máximo de oxigênio é uma variável que apresenta associação com a performance esportiva dos atletas. Seus valores podem ser diferentes de acordo com a posição tática. Objetivo: O objetivo do presente estudo foi comparar a potência aeróbia máxima de jogadoras de futebol de acordo com suas diferentes posições do sistema de jogo. Materiais e métodos: Participaram do estudo 18 atletas de futebol do sexo feminino (três zagueiras, quatro laterais, cinco meio-campistas e seis atacantes), com idade média de 19,1 (1,4) anos. Trata-se de um estudo de corte transversal. Foram realizadas as avaliações antropométricas (massa corporal e estatura) e da potência aeróbia máxima (Yo-yo test). Resultados: De acordo com a comparação realizada, não houve diferença estatisticamente significante sobre a potência aeróbia máxima das atletas. Conclusão: Não foram identificadas diferenças significativas quanto ao consumo máximo de oxigênio entre as jogadoras de futebol profissional, independentemente das posições de jogo.
