SUMMARY OBJECTIVES: The present study compared cardiorespiratory capacity between cirrhotic patients and healthy subjects. METHODS: Nineteen cirrhotic patients and 19 healthy subjects, paired by age and gender, participated in the study. Volunteers performed an incremental cardiopulmonary test with a ramp protocol, a ventilatory and metabolic variables were obtained and analyzed. The recovery was analyzed by calculating the time needed for 50% of oxygen consumption (VO2) recovery to occur as the median between the peak of the exercise and the end of recovery on the VO2 curve (T1/2). The VE/VCO2 slope were performed by the linear regression of ventilation (VE) and carbon dioxide production (VCO2) data. RESULTS: During resting condition, cirrhotic patients presented significantly higher levels of VO2 compared to healthy subjects. The VE/ VO2 and VE/ VCO2 values were significantly higher in the control group at the anaerobic threshold and at the peak of the test compared to cirrhotic patients. Time under effort was significantly higher for healthy subjects. CONCLUSIONS: Based on these findings, it is possible to conclude that liver cirrhosis can compromise the patients’ quality of life, mainly by inducing metabolic alterations which can impair functional capacity and lead to a sedentary lifestyle.

OBJETIVO: Verificar a influência de diferentes sequências de exercícios no desempenho do número de repetições máximas em mulheres idosas. MÉTODOS: Doze mulheres idosas (65,7 ± 5,6 anos, 66,9 ± 9,5 kg, 1,56 ± 0,67 m; 27,4 ± 3,6 kg/m2) foram submetidas a diferentes sequências de exercícios no Treinamento Resistido. Na primeira visita, as voluntárias foram submetidas à anamnese, avaliação antropométrica e teste de 10 RM. Na segunda visita, foi feito um re-teste de 10RM. Na terceira e quarta visita, as voluntárias realizaram as duas sequências: SEQ A - supino horizontal, puxador alto fechado, rosca bíceps e rosca tríceps e, SEQ B - a ordem foi inversa. O desempenho foi medido pelo número de repetições em cada exercício. A fim de verificar as diferenças nos dados obtidos no desempenho em diferentes sequências e séries, foram realizadas medidas repetidas pela ANOVA two-way seguido do teste post-hoc de Tuckey. RESULTADOS: Os resultados demonstraram que o número de repetições de cada exercício variou significativamente entre as sequências nos exercícios de supino horizontal, rosca bíceps e rosca tríceps. CONCLUSÕES: A ordem dos exercícios realizada em uma sessão de treinamento resistido pode afetar o desempenho no número de repetições em mulheres idosas.

OBJECTIVE: Verify the influence of different exercise orders on the performance of the number of maximal repetitions in older women. METHODS: Twelve older women (65.7 ± 5.6 years, 66.9 ± 9.5 kg, 1.56 ± 0.67 m, 27.4 ± 3.6 kg/m2) underwent four nonconsecutive visits and two different orders of Resistance Training. At the first visit, the volunteers were submitted to anamnesis, anthropometric evaluation and a 10RM test. On the second visit, a re-test of 10RM was performed. On the third and fourth visits, the volunteers performed two exercise sequences: sequence A: bench press, latissimus pulldown close grip, biceps curl, triceps extension; for sequence B the order was inverted. Performance was measured by the number of repetitions in each exercise. To determine differences in performance for sequence A vs. sequence B, repeated measures were performed by two-way ANOVA followed by the Tuckey post-hoc test. RESULTS: The number of repetitions of each exercise varied significantly for the bench press, biceps curl and triceps extension between the exercise sequences. CONCLUSIONS: The order of the exercises performed in a resistance training session can affect the performance in the number of repetitions in older women.
