title: Left ventricular structure and function, assessed by imaging and Doppler echocardiography, in athletes engaged in throwing events.
abstract: Ten male athletes engaged in throwing events and ten control subjects, matched for age, height, and weight, were investigated with echocardiography and Doppler velocimetry to assess cardiac structure and systolic and diastolic left ventricular function at rest. Left ventricular (LV) internal diameter, wall thickness, LV mass, and systolic LV function were not different between athletes and nonathletes. The possibility that strength training could alter LV diastolic function was further investigated. Both early diastolic function, estimated from the velocity of LV relaxation and the LV inflow pattern, and late diastolic function, assessed by Doppler velocimetry, were similar in throwers and controls. The unchanged ratio of the peak velocities of LV filing during atrial contraction and early filling suggests that LV distensibility is unaltered in these athletes. In conclusion, the amount and type of training performed by these throwers was not associated with changes in LV structure and function.
