The regulation of erythropoiesis via hemodynamic stimuli such as reduced central blood volume (CBV) remains uncertain in women and elderly individuals. This study assessed the acute effects of lower body negative pressure (LBNP) on key endocrine biomarkers regulating erythropoiesis, that is, erythropoietin (EPO) and copeptin, in young and older women and men (n = 87). Transthoracic echocardiography...

The contribution of body composition to sex differences in strong prognostic cardiorespiratory variables remains unresolved. This study aimed to elucidate whether body composition determines sex differences in cardiac and oxygen (O2) uptake responses to incremental exercise.
Methods
Healthy, moderately active women and men (n = 60, age = 60.7 [12.3] years) matched by age and cardiorespiratory...
