Ventilatory inefficiency (high volume of expired air/volume of carbon dioxide eliminated [Ve/Vco2] slope), and impaired exercise tolerance (low peak volume of oxygen consumption) obtained from cardiopulmonary exercise testing (CPX) strongly predict mortality in heart failure (HF) patients; however, other CPX variables may also contain prognostic information. Therefore, the purpose of ...

Recently a larger hippocampus was found in exercising mice and men. Here we studied the morphological underpinnings in wheel running mice by longitudinal magnetic resonance imaging. Voxel-based morphometry revealed that running increases hippocampal volume by inhibiting an early age-related gray matter loss. Disruption of neurogenesis-related neuroplasticity by focalized irradiation is ...

Numerous studies have reported that the hippocampus in schizophrenia patients is reduced in volume compared to the normal population. Antipsychotic medications have had mixed benefits in maintaining hippocampal volume or reversing volume loss. Recent evidence indicates that routine aerobic exercise represents a promising intervention for reversing hippocampal loss and cognitive ...
