“…Similarly, in several studies, no differences were seen between the athletes and non-athletes in the RVFAC (6). If there were any, smaller RV changes seemed to be in athletes than in non-athletes: La Gerche et al (11) and Teske et al (23) found smaller RV ejection fraction in endurance athletes; Poh et al (20) found a smaller RVFAC in elite speed-skaters than in non-athletes.…”

Characteristics of the athlete's heart have been investigated mostly in the left ventricle (LV); reports referring to the right ventricle (RV) have only appeared recently. The aim of the present study was to compare the training effects on RV and LV in elite male endurance athletes. To this end, echocardiography was conducted in 52 elite endurance athletes (A) and in 25 non-athletes (NA). Differences between A and NA in the morphology was more marked in the RV (body-size-matched (rel.)) long axis diastolic diameter (RVLADd): 63.4 ± 6.3 vs. 56.4 ± 6.3; rel. short axis diastolic diameter (RVSADd): 27.3 ± 3.6 vs. 23.6 ± 2.7 mm/m, RV diastolic area 28 ± 5.0 vs. 21.3 ± 4.3 cm 2 in all cases, p < 0.001) than in the LV (rel. LVLADd: 63.8 mm/m ± 5.6 vs. 60.7 mm/m ± 6.6, p < 0.05, rel.LVSADd 37.8 ± 3.1 vs. 35.3 ± 2.4, no difference). In the athletes ratios of peak early to late diastolic filling velocity (2.07 ± 0.51 vs. 1.75 ± 0.36, p < 0.01), the TDI-determined E'/A' ratio in the septal (1.89 ± 0.55 vs. 1.62 ± 0.55, p < 0.05) and lateral (2.62 ± 0.72, vs. 2.18 ± 0.87, p < 0.001) walls were significantly higher than in NA only in the LV. Results indicate that in male endurance athletes morphologic adaptation is similar or slightly stronger in the RV than in the LV, functional adaptation seems to be stronger in the LV.

“…21,22 supported by recent prospective studies, have stimulated interest in RV adaptation to exercise. 23,24 Additional data have provided further insights into RV adaptation by showing that the RV has to endure a disproportionately higher increase in hemodynamic afterload compared to the LV during intense exercise. 25 Right ventricular structure in collegiate endurance-trained (rowing) and strength-trained (football) athletes was recently assessed before and after 90 days of team-based exercise training.…”

Athletic heart syndrome refers to the physiological and morphological changes that occur in a human heart after repetitive strenuous physical exercise. Examples of exercise-induced changes in the heart include increases in heart cavity dimensions, augmentation of cardiac output, and increases in heart muscle mass. These cardiac adaptations vary based on the type of exercise performed and are often referred to as sport-specific cardiac remodeling. The hemodynamic effects of endurance and strength training exercise lead to these adaptations. Any abnormalities in chamber dilatation and left ventricular function usually normalize with cessation of exercise. Athletic heart syndrome is rare and should be differentiated from pathologic conditions such as hypertrophic cardiomyopathy, left ventricular noncompaction, and arrhythmogenic right ventricular dysplasia when assessing a patient for athletic heart syndrome. This paper describes specific adaptations that occur in athletic heart syndrome and tools to distinguish between healthy alterations versus underlying pathology.

“…Cardiac function has also been assessed using echocardiography and a global decrease in both systolic and diastolic RV (Neilan et al, 2006;Poh et al, 2008) and LV (Banks et al, 2011;George et al, 2009) function in recovery from prolonged endurance exercise reported in conjunction with the acute structural adaptations. The right-sided ECG changes evident in the current study may represent an electrical adaptation linked to these structural and functional changes and provide further insight into the acute electrical adaptations in response to a bout of ultra-endurance exercise.…”
