Effects of Exercise on the HeartSlide2
Training= heart to get bigger like any other muscleHypertrophy (Cardiac)
Athletes heartIncrease in thickness of muscle and ventricle wall
Effects of Exercise on the HeartSlide3
Increased diastolic fillingIncreases in strength of contraction
Increased Stroke Volume
What does this mean for the heart?Slide4
When we train we see an increase in blood volumeSo increase in venous return
Starlings lawGreater contraction more blood ejected per beat
Heart rate will decrease
What does this mean for the heart?Slide5
Reduction in resting heart rate as a result of training Below 60 beats per minute
Bradycardia
Slide6
Q= SV x HRTraining increases Stroke volume so heart rate goes down
Less demand for oxygen by the heart as less energy required to beatMORE O2 available to muscles
Bradycardia

How can an untrained performer have the same cardiac output as the fit performer for a given workload?
