Does not alter human practice; leaves open whether endurance training enhances LV performance in patients with heart disease.
Does endurance training improve myocardial performance in a canine model?
p-value: p=<0.001
Endurance training in a canine model improves left ventricular pump performance through both heterometric autoregulatory adjustments and extracardial adaptations.
RÄMÖ et al. (1987) studied Healthy (canine) (n=14). Endurance training (treadmill running) vs. Control group was evaluated on Slope of the regression line between stroke work and end-diastolic volume (p=<0.001). Endurance training by treadmill running for 6-7 weeks in beagle dogs significantly increased the slope of the stroke work to end-diastolic volume relationship (P<0.001).
