We studied 11 healthy untrained volunteers (aged 28.9±4.6 years) during 60 minutes of
aerobic ergometric exercise with constant heart rates of 130 to 140 beats/minute. We found …

The purpose of this study was to examine, in male adolescents, the effects of long-term
endurance training on cardiac structure and function, by adopting a cross-sectional …

We aimed to clarify the myocardial adaptation to short-term high-intensity exercise among
trained athletes. We screened 17 participants in the 2004 World Indoor Rowing …

It is unclear whether cardiovascular responses to heavy isometric exercise are changed by
intensive training. We evaluated the effects of this type of exercise on left ventricular (LV) …

Despite an abundance of early clinical descriptions of the athlete's heart, an understanding
of the alterations in cardiac mechanics induced by intensive exercise participation awaited …

A number of cardiac variables have been reported to be influenced by long-term isotonic
exercise training (2, 3, 6, 7, 15, 17, 20). Echocardiographic parameters, especially left-sided …

The effect of extremely exhaustive exercise on left ventricular performance was studied
echocardiographically in 13 experienced male ultramarathon runners who took part in a …

Gilbert et al.[1] compared M-mode echocardiographic measurements of 20 endurance
runners to 26 young sedentary subjects. A modest degree of right and left ventricular …

A protocol which combines the noninvasive measurement of cardiac output, systolic time
intervals (STIs), and blood pressure was used to evaluate the effects of jogging on cardiac …

To assess left ventricular structure and function at rest and during exercise in endurance
athletes, 10 elite marathon runners, aged 28 to 37 years, and 10 matched nonathletes were …
