Mechanisms of Exercise Intolerance
Background—A decreased ratio of early to late diastolic mitral inflow velocities (E/A 1.0) reflects slowing of left ventricular (LV) relaxation. This finding is widely believed to indicate significant diastolic dysfunction. However, E/A 1.0 is common during normal aging and often is not associated with symptoms of heart failure. We asked (1) whether slowed LV relaxation is associated with exerc...

BACKGROUND A decreased ratio of early to late diastolic mitral inflow velocities (E/A <1.0) reflects slowing of left ventricular (LV) relaxation. This finding is widely believed to indicate significant diastolic dysfunction. However, E/A <1.0 is common during normal aging and often is not associated with symptoms of heart failure. We asked (1) whether slowed LV relaxation is associated with exe...
متن کاملMechanisms of orthostatic intolerance following very prolonged exercise.
Nine men completed a 24-h exercise trial, with physiological testing sessions before (T1, approximately 0630), during (T2, approximately 1640; T3, approximately 0045; T4, approximately 0630), and 48-h afterwards (T5, approximately 0650). Participants cycled and ran/trekked continuously between test sessions. A 24-h sedentary control trial was undertaken in crossover order. Within testing sessio...
