After the cessation of physical activity for six or more years, processes start to occur in previously active sportsmen that cause aerobic capacity to reach the values observed in people of the same age who have never participated in sport. However, the physical capacity of these people remains above the average level for the same age group. The important factors related to the aerobic capacity of ex-elite sportsmen are the age, current physical activity and body weight. There is no relationship between their maximal aerobic capacity and the type of sport discipline practiced by the ex-athlete in the past.

Exercise intolerance, a hallmark of heart failure with preserved ejection fraction (HFpEF) exacerbated by obesity, involves unclear mechanisms related to skeletal muscle metabolism. In a "2-hit" model of HFpEF, we investigated the ability of exercise therapy (voluntary wheel running) to reverse skeletal muscle dysfunction and exercise intolerance. Using state-of-the-art metabolic cages and a multiomic approach, we demonstrate exercise can rescue dysfunctional skeletal muscle lipid and branched-chain amino acid oxidation and restore exercise capacity in mice with cardiometabolic HFpEF.

Background: HIV-associated neurocognitive disorder (HAND) affects an individual's capacity for independence and engagement in everyday activities, posing challenges in environments with limited resources and low social support.
Objectives: To ascertain the efficacy of exercise (AE) for activity and participation (AP) level in people with HAND.
Method: This is a randomised controlled trial that is parallel-group in nature, with intention-to-treat analysis and disguised allocation.

Exercise is a well-documented, nonpharmacologic treatment for individuals with autonomic dysfunction and associated orthostatic intolerance, such as postural tachycardia syndrome and related disorders. Exercise has been shown to increase blood volume, reverse cardiovascular deconditioning, and improve quality of life. Current first-line standard of care treatment for autonomic dysfunction combines graded approaches to exercise with medications and lifestyle modifications.

Background: Tracheal extubation failure after cardiac surgery is associated with diminished cough strength, albeit the information on cough strength in post-cardiac surgery patients is limited.
Aim: To investigate the cough strength in patients after cardiac surgery before tracheal extubation and the related influencing factors.
Study Design: A cross-sectional study was designed, with adherence to the STROBE guidelines.
