What anatomical adaptations/changes occur in the heart with an appropriate endurance training programme
Homework Answers
Following adaptations/ changes occurs in the heart with an appropriate endurance training program:
1. Size of the heart increases which allows more stretching in left ventricle and thus fill with more blood resulting into increased stroke volume, increased cardiac output.
2. The heart muscles wall thickness is increased which enhances the contractility of the heart resulting into increased blood supply to the body tissues.

Which statement concerning cardiovascular changes to endurance training is not correct? Left ventricular mass is approximately 45% greater in highly trained athletes Resting bradycardia is often seen after prolonged endurance training Maximal heart rate will increase, but only after years of training Decreases in hematocrit are a result of plasma volume expansio

Is resting HR, Q, or SV influenced by endurance training? If yes, what is/are the mechanism(s) for training-induced alterations in SV (SV = EDV – ESV) and HR? Does endurance training influence submaximal and maximal SV or Q? If yes, how does this occur and to what extent? Is maximal HR influenced by...

Name two physiological changes that occur in the muscle due to exercise training which allow an individual to improve their fitness (VO2max)? Why do these changes result in a change in overall fitness? Does max HR change with training? Are there any cardiac adaptations to long-term exercise training?

3) In what ways do aerobic training adaptations lead to glucose sparing as well as preferential fat oxidation at sub- maximal workloads? 4) How do acrobic training adaptations lead to faster transition from rest to steady state (less oxygen deficit) as well as less production of lactate? 5) During Aerobic exercise there are increases in intracellular Ca2+, increased AMP/ATP ratio, as well as oxidative stress (free radicals). These are primary signals within the muscle cells. What are the secondary signals...
