“…While our and previous studies agree on normal systolic function (15,17), previous studies have been conflicting with regard to diastolic function in athletes. Doppler-echocardiography and tissue Doppler imaging studies have shown either normal (12,17,(31)(32)(33)(34)(35) or augmented diastolic function (36 -39). A disadvantage of some of the previous studies is the lack of age-and sex-matched groups of sedentary controls (31,36,38).…”

Purpose: To study young adult elite athletes with age-and sex-matched sedentary controls to assess sex-specific differences for left ventricular (LV) and right ventricular (RV) volumes and mass as well as for LV contraction and relaxation. Materials and Methods:A total of 23 male athletes (mean age 25 Ϯ 4 years, training 22 Ϯ 7 hours/week in rowing, swimming, or triathlon) and 20 female athletes (mean age 24 Ϯ 4 years, training 19 Ϯ 5 hours/week in rowing, swimming, or triathlon) and age-and sex-matched sedentary controls (21 male/17 female) underwent cardiovascular magnetic resonance (CMR) imaging (1.5 Tesla). Cardiac phase contrast imaging using a black-blood k-space segmented gradient echo sequence was used for analysis of cardiac contraction and relaxation and steady-state freeprecession cine images were acquired for determination of cardiac volumes and mass.Results: Male and female athletes showed similar increases in LV and RV volume and mass indices when compared to controls (ranging between 15% and 42%). No sexspecific differences in training effect on LV and RV volumes, mass indices, and ejection fractions, as well as LV to RV ratios of these volume and mass indices (parameters of balanced LV and RV dilatation and hypertrophy) were observed (all P for interaction Ͼ0.05). Similarly, no sex-specific differences in training effect on cardiac contraction and relaxation were found (all P for interaction Ͼ0.05). Conclusion:Young adult elite athletes do not show sexspecific adaptive structural and functional changes to exercise training in accordance with the benign nature of the hypertrophy associated with athlete's heart.

Hypertrophic cardiomyopathy (HCM) is the number one cause of sudden cardiac death in elite athletes. This project used resting 12-lead electrocardiography (ECG) and ballistocardiography (BCG) to assess cardiac cycle timing events as simple screening techniques to rule out cardiac abnormalities for the safety of a group of elite ice hockey players. Clinical cardiac (ECG) and physiological (maximal aerobic power [VO 2 max], anaerobic [Wingate peak power, Watts] and musculoskeletal strength) data is presented here on an elite group of ice hockey players (n=34; age=17-18 yrs) that participated in a professional medical and fitness evaluation. Subsequently one subject was diagnosed with #1 Apical HCM and his cardiac data is compared with the group. The HCM subject performed all fitness testing and was determined to be physically fit (%BF=7.2%; VO 2 max=59.4 mL•kg -1 •min -1 ; Wingate peak power output=15.1 Watt•kg -1 ; Heart Rate max=200 beats•min -1 ). However, the ECG showed extreme voltage and deeply inverted T-waves, and the BCG showed abnormal waveform complexes and cardiac timing events in comparison to the group means. Mean BCG systolic timing events for isovolumic contraction time ) and LV ejection fraction (62%). Cardiac magnetic resonance imaging (MRI) showed apical septal wall thickness (24-25 mm) in the HCM player. In conclusion, BCG was able to corroborate a cardiac abnormality that was later confirmed with echocardiography and MRI, suggesting that BCG is a potential technology to detect anomalies that alter cardiac timing and amplitude.

Usefulness of Doppler echocardiographic assessment of diastolic filling in distinguishing "athlete's heart" from hypertrophic cardiomyopathy

Abstract: Doppler echocardiographic indices of left ventricular filling may aid in distinguishing between pronounced physiological hypertrophy due to athletic training and pathological hypertrophy associated with hypertrophic cardiomyopathy.
