Background Physical inactivity and low cardiorespiratory fitness (CRF) are associated with higher risk of heart failure. However, the independent contributions of objectively measured sedentary time, physical activity, and CRF toward left ventricular (LV) structure and function are not well established. Methods and Results We included 1368 participants from the DHS (Dallas Heart Study) (age, 49 years; 40% men) free of cardiovascular disease who had physical activity and sedentary time measured by accelerometer, CRF estimated from submaximal treadmill test, and cardiac magnetic resonance imaging performed using 3‐T magnetic resonance imaging. A series of linear regression models were constructed to evaluate the associations of sedentary time, moderate physical activity, vigorous physical activity, and CRF with LV parameters after adjustment for established cardiovascular risk factors. We observed a modest correlation between CRF levels and objectively measured moderate (correlation coefficient, 0.17; P <0.001) and vigorous physical activity (correlation coefficient, 0.25; P <0.001) levels. In contrast, sedentary time was not associated with CRF. In adjusted analysis, both vigorous physical activity and higher CRF were significantly associated with greater stroke volume, LV mass, LV end‐diastolic volume, and lower arterial elastance, independent of other confounders. Sedentary time and moderate physical activity levels were not associated with LV parameters. Conclusions Vigorous physical activity and CRF are significantly associated with cardiac structure and function parameters. Future studies are needed to determine if interventions aimed at improving CRF levels may favorably modify cardiac structure and function.

Introduction: Physical activity (PA) is associated with cardiovascular health benefits including prevention of age related cardiac remodeling, systolic and diastolic dysfunction, and adaptive pro-hypertrophic effect. In this study we aim to measure the associations between PA and LV structure and function in a diverse Hispanic/Latino population. Methods: Participants included 1,818 self-identified Hispanic/Latino men and women, age 45-74 from the Echocardiographic Study of Latinos (ECHO-SOL). Standard echo measures included M-mode, two-dimensional (2-D), spectral, tissue Doppler and color flow. Participants wore an Actical hip accelerometer for 1 week. Multivariable regression models were completed to relate PA to echocardiographic parameters. Results: The mean ± SE age for the cohort was 56 ±0.4, 57% were female, the prevalence of diabetes was 28%, hypertension 50%, hypercholesterolemia 49%, and coronary heart disease 7%. Average moderate to vigorous PA (MVPA) was 20.9 ± 1.1 min/day and sedentary time ±SE was 736.5 ± 8.1 min/day. In multivariable models adjusted for age, gender, diabetes, hypertension, hypercholesterolemia, coronary heart disease, alcohol and cigarette use we found the following: left atrium volume index (LAVI) decrease by quartiles of MVPA (p-value<0.001). Global circumferential strain (GCS) decreased across these quartiles of MVPA. Moreover, LAVI decreased by 0.3 per 100 min/day of sedentary time (p-value<0.01) and GCS also decreased across quartiles of sedentary time. Conclusion: MVPA was significantly associated with lower LAVI. There was also a significant association with sedentary behavior. Our findings illustrate the complex relationship between PA, sedentary time and cardiac structure and function.

Very high results, the achievement of which is possible only with long systematic train-ing with the use of large and sometimes excessive physical activity characterizes modern sports. The preparation process from beginner to master of sports takes an average of 5–10 years. During this time, the athlete must develop and improve special physical and mental qualities, as well as master certain motor skills specific to this sport. Therefore, children's and youth's organisms of athletes are subject to increased loads, especially in classes that develop endurance. But not always physical activity contributes to the strengthening of the body, sometimes excessive loads, especially with the wrong approach, lead to complications from the cardiovascular system, in particular, to changes in heart rate. Therefore, the issue of adapting the functions of the heart of young athletes to muscle loads becomes increasingly important. The purpose of the work was to study the activities of the cardiovascular system of skiers-riders in the preparatory period of the one-year cycle. Currently, various methods of functional diagnosis of the cardiovascular system are used. We considered the results obtained during electrocardiographic examination of skiers-riders. We investigated electrical activity of the heart and presented model characteristics according to the considered indicators.
