Abstract Cardiac function is a major determinant of cardiopulmonary fitness. This study aimed to determine if novel echocardiographic myocardial and efficiency parameters at rest can predict exercise performance during different types prolonged high‐intensity endurance exercise. Echocardiography was performed before in 40 healthy (75% males) 50.3 ± 9.1‐year‐old recreational athletes. Echocardiographic were compared with assessed by power output two exercises: A lactate threshold test (La‐CPET) 91‐km mountain bike sport cycling race. The La‐CPET had median duration 43 (40, 45) minutes mean 2.9 0.5 W/kg. race 236 (214, 268) 2.1 There moderate left ventricular (LV) dilatation individuals the highest performance. parameter, global wasted work (GWW), positively correlated (rho = 0.42, p 0.008) negatively both −0.43, 0.007) −0.44, 0.005).

Endurance athletes have a high prevalence of atrial fibrillation (AF), probably caused by exercise-induced cardiac remodelling. Athletes diagnosed with AF are often advised to reduce the intensity and amount training but efficacy this intervention has not been investigated in endurance AF.

Objective: Olympic athletes (OAs) represent a unique subset of highly trained subjects achieving extraordinary performance. Differences between OAs and elite/national (EAs), defined as not qualified for the Olympics, are investigated. Design: Therefore, we compared with EAs enrolling 1472 (63.6% OAs; 56.9%, men, mean age 25.8 ± 5.1 years) power (24.7%), skills (12.5%), endurance (20.8%), mixed (37.4%) disciplines performing clinical, anthropometric, echocardiographic, exercise stress, blood test analysis. Results: were older (power: 25.9 4.6 vs 24.1 4.7, P = 0.0002; skills: 28.6 6.5 25.2 6.5, 0.0003; endurance: 27.2 4.5 23.7 3.9, 0.001; mixed: 27.9 4.7 22.8 4.4, 0.001) more hours 26.1 10.9 19.9 7.5, < 0.0001; 29.1 9.4 21 9.4, 0.0004; 26.4 8.7 19.4 8.5, 28.4 9.5 22.2 9.2, EAs. No morphological cardiac differences observed. At test, maximum watt reached was similar (except that in power, 0.004). showed statistically significant lower serum calcium, thyroid stimulating hormone, relatively higher total low-density lipoprotein cholesterol. Conclusions: older, have larger body mass, can sustain training volume than elite athletes. However, no major remodeling or clinical laboratory parameters differentiate these 2 groups.

Of the 364 included, 36.5% were female. Compared with males, achieved lower VO2peak (51 (40-57) vs 59 (41-65) mL/kg/min, p<0.001), had smaller absolute body surface area (BSA)-indexed left right end-diastolic volumes (LVEDV, respectively) similar when indexed fat-free mass. Both sexes showed strong association LVEDV (r=0.60-0.66) coefficient describing linear relationship (Females: VO2peak(mL/min)=12.1×LVEDV+963.9; males: VO2peak=15.3×LVEDV+806.8, p=0.100) BSA-indexed (females: (mL/kg/min)=0.37×LVEDV/BSA+12.5; VO2peak=0.51×LVEDV/BSA-1.2, p=0.059). There was no difference ventricular (RV) VO2peak; however, males 3.8 times higher odds reduced RV ejection fraction. Prevalent myocardial scar both (14.2%) (19.9%) (p=0.180). Female demonstrate scar. The athlete's heart can show profound adaptation, previous assertions that hearts have lesser capacity should be reappraised.

In athletes, left ventricular hypertrophy (LVH) criteria based on electrocardiograms (ECG) have been validated almost exclusively in men using echocardiography. Sex-specific cardiac magnetic resonance (CMR) validation is lacking. To evaluate ECG-LVH against contrast-enhanced CMR male and female elite athletes. Cross-sectional study healthy Eight of voltages products as well QRS duration were quantified automated ECG analysis, compared to CMR-derived LVH indicators (indexed mass (LVM) maximum wall thickness (maxLVWT)). Primary metrics interest sex-specific correlations (ρ) between LVM/maxLVWT. Secondary included discriminative performance (AUROC) sensitivity at 95%-specificity level for detecting increased LVM or maxLVWT. Among 209 athletes (median age 25, 45% female), more frequently met one voltage than women (64% vs. 45%, p=0.010). men, no showed meaningful Only demonstrated (AUROC: 0.67; maxLVWT 0.74). women, all product correlated with (ρ=0.25-0.45) acceptable discrimination 0.63-0.73).
