Introduction: The aim of this study was to investigate the effect of an 8-week resistance exercise program on balance, walking speed, and muscle strength in elderly women.   Methods: This randomized controlled trial was performed on 50 elderly women aged 60-66 years who were assigned to two groups of experimental and control. The Time Up and Go test, was used to measure dynamic balance, Rombe...

We report a case of improved cardiopulmonary exercise (CPX) test outcomes measured 48 h after initial CPX testing and immediately after alterations were made to the settings of a dual chamber, dual sensing pacemaker with exercise detection. The changes allowed successful abdominal surgery to be completed.

this study was conducted to compare of inflammatory markers response in serum and saliva of healthy men following an exhaustive exercise test. twenty two volunteer healthy men (aged 20-30 years and body fat 10-16%) in a quasi-experimental, single group design participated in bruce exercise test. serum and saliva samples were collected immediately before and after the exercise test. c-reactive p...

The purpose of this study was to develop a standardized and externally paced field test (15-m Incremental Shuttle Walk and Run Test [15mISWRT]), incorporating an incremental and progressive structure, to assess aerobic fitness in middle-aged adults. 68 middle-aged men performed three tests in random order between one to two week intervals: 15-m ISWRT, cardiopulmonary exercise test (CPX), and 15...

BACKGROUND The rest-exercise-rest transition is accompanied by rapid and slow heart rate (HR) changes modulated by the branches of the autonomic nervous system. Vagal participation seems to be distinct in these different transitions. Additionally, it is methodologically difficult to determine the best moment and how to measure resting HR. OBJECTIVE To determine the association between initial...

OBJECTIVE To determine the prevalence of exercise-induced bronchoconstriction among elite long-distance runners in Brazil and whether there is a difference in the training loads among athletes with and without exercise-induced bronchoconstriction. METHODS This was a cross-sectional study involving elite long-distance runners with neither current asthma symptoms nor a diagnosis of exercise-ind...

The aim of this study was to determine the accuracy of midregional pro-A-type natriuretic peptide (MR-proANP) for the identification of a cardiocirculatory exercise limitation (CL) as assessed by cardiopulmonary exercise testing (CPET) and to compare it to B-type natriuretic peptide (BNP). Among 94 patients with CPET data fulfilling criteria for appropriate effort and sufficient diagnostic cert...

The effect of exercise on ventilation heterogeneity has not been investigated. We hypothesized that a maximal exercise bout would increase ventilation heterogeneity. We also hypothesized that increased ventilation heterogeneity would be associated with exercise-induced arterial hypoxemia (EIAH). Healthy trained adult males were prospectively assessed for ventilation heterogeneity using lung cle...
