The effect of incremental endurance exercise training on left ventricular mechanics: a prospective observational deformation imaging study.
OBJECTIVE Exercise training has been known to cause structural and functional alterations in the heart called athletes heart. We aimed to investigate the effects of incremental endurance exercise training (IEET) on the left ventricular (LV) mechanics in healthy subjects. METHODS This prospective observational study included 34 healthy young men who participated in competitive sports. The part...
متن کاملEffect of ultra-endurance exercise on left ventricular performance and plasma cytokines in healthy trained men.
The purpose of this study was to investigate the effect of ultra-endurance exercise on left ventricular (LV) performance and plasma concentration of interleukin (IL)-6, IL-10, IL-18 and tumour necrosis factor alpha (TNF-α) as well as to examine the relationships between exercise-induced changes in plasma cytokines and those in echocardiographic indices of LV function in ultra-marathon runners. ...
متن کاملAltered ventricular mechanics after 60 min of high-intensity endurance exercise: insights from exercise speckle-tracking echocardiography.
Transient reductions in myocardial strain coupled with cardiac-specific biomarker release have been reported after prolonged exercise (>180 min). However, it is unknown if 1) shorter-duration exercise (60 min) can perturb cardiac function or 2) if exercise-induced reductions in strain are masked by hemodynamic changes that are associated with passive recovery from exercise. Left ventricular (LV...
متن کاملLeft ventricular mechanics and arterial-ventricular coupling following high-intensity interval exercise.
High-intensity exercise induces marked physiological stress affecting the secretion of catecholamines. Sustained elevations in catecholamines are thought to desensitize cardiac beta receptors and may be a possible mechanism in impaired cardiac function following strenuous exercise. In addition, attenuated arterial-ventricular coupling may identify vascular mechanisms in connection with postexer...
متن کاملThe impact of endurance exercise training on left ventricular systolic mechanics.
Although exercise training-induced changes in left ventricular (LV) structure are well characterized, adaptive functional changes are incompletely understood. Detailed echocardiographic assessment of LV systolic function was performed on 20 competitive rowers (10 males and 10 females) before and after endurance exercise training (EET; 90 days, 10.7 +/- 1.1 h/wk). Structural changes included LV ...
