BACKGROUND: Different protocols for the sit-to-stand test (STS) are available for assessing functional capacity in COPD. We sought to correlate each protocol of the STS (ie, the 5-repetition [5-rep STS], the 30-s STS, and the 1-min STS) with clinical outcomes in subjects with COPD. We also aimed to compare the 3 protocols of the STS, to verify their association and agreement, and to verify whether the 3 protocols are able to predict functional exercise capacity and physical activity in daily life (PADL)...

BACKGROUND: A normal heart rate reflects the balance between the sympathetic and parasympathetic autonomic nervous system. When the difference between heart rate at the end of an exercise test and after 1 min of recovery, known as the 1-min heart rate recovery, is ≤ 12 beats/min, this may indicate an abnormal delay. We sought to compare physical activity patterns and subjects' functional status with COPD with or without delayed 1-min heart rate recovery after the 6-min walk test (6MWT)...

BACKGROUND: May patients with interstitial lung disease (ILD) require supplementary oxygen (O2 ) therapy to maintain normoxia. However, ambulatory O2 delivery devices are constraining and cumbersome. The physiologic and symptomatic impact of these devices on ILD patients is unknown. METHODS: We conducted a prospective study of 30 clinically stable ILD patients (with varying disease severity), half of whom used O2 at baseline. Each subject completed two six-minute walk tests (6MWTs); for O2 users, one walk was completed while wearing a backpack (weight 7...

BACKGROUND CONTEXT: To fully understand the extent of limitations associated with symptomatic lumbar spinal stenosis (LSS) and the functional outcome of its treatment, not only function during daily activities (e.g. using the 6-minute walk test (6MWT)) but also the quality of function should be objectively assessed. PURPOSE: To test the hypothesis that the Oswestry Disability Index (ODI) score, the walking distance during the 6MWT (6MWD) and gait quality (spatiotemporal parameters and gait asymmetry) will improve postoperatively and achieve normal values; changes in gait parameters correlate with changes in ODI score; and patients' gait quality will diminish during the 6MWT reflected by changes in gait parameters during the 6MWT...

INTRODUCTION/PURPOSE: Inflammation contributes to heart failure (HF) progression and the interleukin (IL)-1 cytokine IL-1β is implicated in this process. The adaptor protein ASC is necessary for inflammasome activation of IL-1β. Lower ASC methylation is associated with worse outcomes in HF. The purpose of this study was to examine the effects of exercise on changes in ASC methylation and activation of the interleukin-1 family cytokine IL-1β in persons with HF. METHODS: Participants (N=54) were randomized to receive exercise intervention (n=38) or attention control (n=16) for 3 months...
