چکیده
Abstract Funding Acknowledgements Type of funding sources: None. Introduction Endurance training may cause atrial remodeling and arrhythmias in professional athletes. However, there is a lack data on the right (RA) adaptation to half marathon run amateur runners. Recently introduced deformation strain analysis allows assess RA function more precisely. Purpose The study aims influence ten-weeks parameters non-elite It also investigates whether these changes affect runner’s competitive performance. We hypothesized that 21.0975 kilometers itself functional recreational Methods group consisted 45 runners with mean age 32.96 ± 5.12 years, 27 men. Two-dimensional, Doppler speckle tracking echocardiography was performed before period (stage 1), 48 hours 2) within after 3) run. measured volumes, ejection fraction during reservoir, conduit contraction phases at all stages (Figure). Training intensity expressed declared per week. Results There were no significant volumes between stages. did not notice differences strains Athletes who trained intensively had significantly higher maximum volume stage 1 (r = 0.32; p 0.033) 3 0.44; 0.003). They larger area 0.030). Runners whose larger, achieved better finishing race time -0.49; 0.001). Higher correlated performance -0.32; 0.039). Conclusions Ten-weeks participation associated dilatation or based we observed physical enlargement surface atrium, which resulted time.

On site assessment of cardiac function and neural regulation in amateur half marathon runners
OBJECTIVE Strenuous exercise variably modifies cardiovascular function. Only few data are available on intermediate levels of effort. We therefore planned a study in order to address the hypothesis that a half marathon distance would result in transient changes of cardiac mechanics, neural regulation and biochemical profile suggestive of a complex, integrated adaptation. METHODS We enrolled 3...
متن کاملBronchial epithelial damage after a half-marathon in nonasthmatic amateur runners.
High neutrophil counts in induced sputum have been found in nonasthmatic amateur runners at rest and after a marathon, but the pathogenesis of airway neutrophilia in athletes is still poorly understood. Bronchial epithelial damage may occur during intense exercise, as suggested by investigations conducted in endurance-trained mice and competitive human athletes studied under resting conditions....
متن کاملAcute Changes in Inflammatory Biomarker Levels in Recreational Runners Participating in a Marathon or Half-Marathon
BACKGROUND Strenuous physical activity activates the participant's immune responses; however, few studies exist, observing exercise-induced simultaneous changes in mediators of inflammation. METHODS We examined individual responses in soluble urokinase-type plasminogen activator receptor (suPAR), a marker of immune activation, soluble endocytic receptor for haptoglobin-hemoglobin complexes (C...
متن کاملReduction in Post-Marathon Peak Oxygen Consumption: Sign of Cardiac Fatigue in Amateur Runners?
BACKGROUND Prolonged aerobic exercise, such as running a marathon, produces supraphysiological stress that can affect the athlete's homeostasis. Some degree of transient myocardial dysfunction ("cardiac fatigue") can be observed for several days after the race. OBJECTIVE To verify if there are changes in the cardiopulmonary capacity, and cardiac inotropy and lusitropy in amateur marathoners a...
