The ventilatory component of the muscle metaboreflex is overstimulated in transthyretin cardiac amyloidosis patients with poor aerobic capacity.

The exercise pressor reflex, i.e., metabo- and mechano-reflex, partially regulates the control of ventilation and cardiovascular function during exercise.

Effect of 9 weeks continuous vs. interval aerobic training on plasma BDNF levels, aerobic fitness, cognitive capacity and quality of life among seniors with mild to moderate Alzheimer's disease: a randomized controlled trial.

Background: Evidence suggests that aerobic-type training confers physical benefits and appears to contribute positively to brain health. This study aims to compare the effect of 9-weeks continuous (CAT) to interval aerobic training (IAT) on brain derived neurotrophic factor (BDNF) plasma level, aerobic fitness, cognitive performance, and quality of life among senior with Alzheimer's disease (AD).

Methods: 52 participants were randomly allocated into three groups (CAT  = 14; IAT  = 17; and Controls  = 21).

Epicardial fat accumulation is an independent marker of impaired heart rate recovery in obese patients with obstructive sleep apnea.

Background: Sympathetic nervous system activation plays a pivotal role in obese patients with obstructive sleep apnea (OSA), contributing to increased cardiovascular risk. Epicardial adipose tissue (EAT) activates cardiac autonomic nervous system. Our main study objective was to investigate effects of these autonomic dysfunction factors on post-exercise heart rate recovery (HRR).

Effect of Interval and Continuous Aerobic Training on Basal Serum and Plasma Brain-Derived Neurotrophic Factor Values in Seniors: A Systematic Review of Intervention Studies.

The purpose of this systematic review was to provide a comprehensive analysis of the available clinical trials analyzing, in seniors, the effect of interval aerobic training (IAT) and continuous aerobic training (CAT) on peripheral brain-derived neurotrophic factor (BDNF) concentration. We identified 14 randomized or not-randomized intervention studies published up to January 2017 through a computer-assisted search (PUBMED, Pedro, and Science direct data bases). The five trials considering IAT and the nine considering CAT totalized 988 individuals (age range: 58.

Relationship between lower limb muscle strength and 6-minute walk test performance in stroke patients.

Objective: The aim of this study was to determine if lower limb muscle strength and/or spasticity are related to performance in the 6-min walk test (6MWT) in stroke patients.

Methods: A total of 24 patients (12 males and 12 females) participated in the study. Muscle strength (Medical Research Council (MRC) scale) and spasticity (modified Ashworth scale) were assessed prior to the 6MWT.
