The aim of this study was to compare the power outputs of the intermittent critical power (CPi) with the intermittent maximal lactate steady state (MLSSi) and to compare the physiological and perceptual responses exercising at CPi and MLSSi. Ten subjects performed intermittent trials on a cycle ergometer to determine CPi and MLSSi using 30:30 seconds of(More)
INTRODUCTION We aimed to gather knowledge on the cardiac autonomic modulation in patients with fibromyalgia (FM) in response to exercise and to investigate whether this population suffers from chronotropic incompetence (CI). METHODS Fourteen women with FM (age: 46 ± 3 years; body mass index (BMI): 26.6 ± 1.4 kg/m2) and 14 gender-, BMI- (25.4 ± 1.3 kg/m2),(More)
Chronic inflammation is a common feature shared by several autoimmune rheumatic diseases, such as rheumatoid arthritis, systemic lupus erythematosus, idiopathic inflammatory myopathies, systemic sclerosis, and ankylosing spondylitis. Therefore, blocking or reducing inflammation is one of the major treatment strategies in these diseases. In this context,(More)
This study tested the concurrent and construct validity of a newly developed OMNI-Kayak Scale, testing 8 male kayakers who performed a flatwater load-incremented "shuttle" test over a 500-m course and 3 estimation-production trials over a 1,000-m course. Velocity, blood lactate concentration, heart rate, and rating of perceived exertion (RPE), using the(More)
The purpose of this study was to evaluate a novel procedure, based on the perceived exertion threshold (PET) concept, involving non-exhaustive tests (PET14-17) to estimate critical power (CP), as well as to examine the reproducibility of these indices. Twenty young men performed 2 trials (Trial 1 and Trial 2) of 4 exhaustive predictive tests to estimate CP,(More)
OBJECTIVE To evaluate the efficacy of a 3-month exercise training program in counteracting the chronotropic incompetence and delayed heart rate recovery in patients with systemic lupus erythematosus (SLE). METHODS A 12-week randomized trial was conducted. Twenty-four inactive SLE patients were randomly assigned into 2 groups: trained (T; n = 15, 3-month(More)
OBJECTIVES A growing number of studies have suggested that exercise may promote therapeutic effects in patients with idiopathic inflammatory myopathy. This prospective case series study aimed to report on the effects of exercise in patients with persistent active myositis. METHODS Three patients with persistent active polymyositis were submitted to a(More)
Primary antiphospholipid syndrome (PAPS) is associated with increased risk of cardiovascular disease and mortality. Aerobic capacity and cardiac autonomic control are also associated with these risks. The aim of our study was to assess aerobic capacity and cardiac autonomic control in PAPS patients. Thirteen women with PAPS and 13 healthy controls matched(More)
The aim of the present study was to evaluate the effects of an exercise training program on lipid profile and composition of high-density lipoprotein (HDL) subfractions in systemic lupus erythematosus (SLE) patients and healthy controls. A 12-week, randomized trial was conducted. Thirty-three physically inactive SLE patients were randomly assigned into two(More)
INTRODUCTION Our aim was to evaluate the safety and efficacy of a low-intensity resistance training program combined with partial blow flow restriction (BFR training) in a cohort of patients with polymyositis (PM) and dermatomyositis (DM). METHODS In total, 13 patients with PM and DM completed a 12-week twice a week low-intensity (that is, 30%(More)
