Cardiac Adaptations to Sprinting

[Charlie_Francis]

@RyanH

Does anyone know of any work looking at cardiac muscle adaptations to sprint training specifically?

I’m curious if the adaptations are more like those from strength training, endurance training or a mix of the two looking at factors like stroke volume, ejection fraction, systolic and diastolic function (and the accompanying ventricular hypertrophy or dilation).

Thanks.

My experience when looking at sprinters has been that they have the capacity to accelerate the HR rapidly up to high numbers and to recover back down rapidly as well, verses the distance adaptation of bigger stroke vol
