“…A incapacidade para exercitar-se numa bicicleta ergométrica aumenta em cinco e sete vezes, respectivamente, as taxas de morbidade e mortalidade de idosos submetidos a procedimentos cirúrgicos eletivos do tipo abdominal ou torácico não cardíaco. Testes aeróbicos de estresse, como subir escadas, podem ser mais efetivos para estratificação do risco do que a abordagem de cada órgão específico, pois traduzem a reserva do sistema cardiopulmonar 33 . Existe forte correlação entre pneumopatia e complicação pulmonar pós-operatória quando a doença pulmonar é avançada e está associada a VEF 1.0 menor que 35% da prevista 34 , a idade do paciente é superior a 75 anos 35 , ou o local do procedimento cirúrgico é o tórax 36 .…”

Body composition and pulmonary function in the elderly: a 7-year longitudinal study

et al. 2008

Objective: To evaluate over a 7-year follow-up period the relationships between changes in body composition, fat distribution and pulmonary function in a sample of elderly men and women. Design: Longitudinal clinical study. Subjects: A total of 47 women and 30 men aged 71.6±2.3 and 71.7±2.2 years, respectively, at baseline with body mass index (BMI) values of 24.96 ± 3.28 and 27.04 ± 3.35 kg m À2 were followed for 7 years. Measurements: Body weight, waist circumference, sagittal abdominal diameter (SAD), fat-free mass (FFM) and fat mass as measured by dual energy X-ray absorptiometry (DXA) and forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) by spirometry were evaluated at baseline and after a 7-year mean follow-up. Results: In women as in men there were no significant changes in weight, SAD and BMI. A significant decrease in height and FFM was observed in both women and men. Height-adjusted FEV1 and FVC decreased significantly in women and men over the 7-year follow-up. Changes in SAD were the most powerful predictors of 7-year follow-up of FEV1 and FVC after taking into account, respectively, baseline FEV1 and FVC. Linear regression analysis, performed by using 7-year follow-up lung function variables as dependent variables and changes in body composition variables as independent variables, showed that 1 cm SAD increase predicted a decrease in FEV1 and FVC of 31 and 46 ml, respectively, and 1 kg FFM decrease predicted a decrease in FVC of 38 ml. After subdividing our study population into four categories of change in FFM and SAD, patients with decreased FFM and increased SAD showed the highest probability of having a worsening in FEV1 and FVC. Conclusion: Increase in abdominal fat and FFM decline are significant predictors of lung function decline in the elderly. Old subjects developing both abdominal fat gain and FFM loss show the highest probability of developing worsening in lung function.

Abstract. The aim of this study was to estimate the correlation between the function parameters of the respiratory system and the amount of physical activity, body mass index and aerobic and physical fitness in Daugavpils University students. The study involved a group of 191 students of both sexes from Daugavpils University aged 20-36 years.Students (n = 191, 123 females and 68 males, mean age 24.02 ± 0.24 years) underwent measurement of anthropometric values (height, weight), physical (PWC170 index) and aerobic fitness (predicted VO2max), spirometry (tidal volume, breathing frequency (BF), minute ventilation (MV), expiratory reserve volume (ERV) and vital capacity (VC) and filled in International Physical Activity Questionnaire (IPAQ).Both MV and VC were directly and statistically significantly associated with aerobic fitness, physical fitness and amount of physical activity. Vigorous PA independently was directly and statistically significantly associated with physical fitness and aerobic fitness. After adjusting for sex, BF was inversely and statistically significantly associated with physical activity amount in female. Both female and male had inverse and statistically significant association of BMI and relative VO2max.Reduced lung volumes were associated with lower aerobic fitness, lower physical fitness and lower amount of weekly physical activity. Healthier body mass index was associated with higher aerobic fitness (relative VO2max) in both female and male.
