Article Synopsis
- * The main causes of sarcopenia include aging, chronic diseases, lack of exercise, and inadequate nutrition, particularly low protein intake, which affects the balance between muscle growth and breakdown.
- * Nutritional strategies like animal and plant-based protein supplements, along with other compounds like leucine and creatine, have shown promise in improving sarcopenia outcomes, though the effectiveness of some other supplements is still uncertain.
Purpose: Central and peripheral chemoreceptors are hypersensitized in patients with heart failure with reduced ejection fraction. Whether this autonomic alteration occurs in patients with heart failure with preserved ejection fraction (HFpEF) remains little known. We test the hypothesis that the central and peripheral chemoreflex control of muscle sympathetic nerve activity (MSNA) is altered in HFpEF.

It is unclear whether muscle blood flow (MBF) is altered in long-term Hodgkin lymphoma (HL) survivors. We tested the hypothesis that ) MBF response during mental stress (MS) is impaired in long-term HL survivors and ) aerobic exercise training combined with local strength exercise (ET) restores MBF responses during MS in these survivors. Eighteen 5-year HL survivors and 10 aged-paired healthy subjects (HC) were studied.

The aim of this study was to determine if physical capacity increase in patients HFrEF is associated with muscle sympathetic nerve activity (MSNA) reduction and muscle blood flow (MBF) increase.
Methods: The study included 124 patients from a 17-year database, divided according to exercise training status: 1) exercise-trained (ET, n = 83) and 2) untrained (UNT, n = 41).
