Okay so, Andrea is wanting to improve flexibility. The question is asking what would NOT compliment her present work out. She is already doing flexiblity and strength buliding exercises.
Biking- This is a cardio exercise and will work on her endurance
Cross Country Skiing- I am not really sure what all this has to deal with but I assume cardio and strength buliding
Swimming- This is as well a cardio and can be for strength training.
Weightlifting- is a strength buliding exercise.
I am going on a whim here, but I believe the answer is Biking because biking is the only one that is normally only used as a cardio exercise, and Andrea is wanting to improve her flexiblity.
The process of heart contraction stimulates by the initiation of an electrical impulse. This electrical impulse starts in the SA node.
<h3>What is the Heart contraction?</h3>
Heart contraction may be defined as a type of physiological activity that stimulates electrical impulses which are initiated by the sinoatrial node. Systole is significantly the contraction phase of the cardiac cycle.
The SA node is a small bundle of specialized cells that is remarkably located in the right atrium. The electrical activity escalates through the walls of the atria and induces them to contract. This action finally forces blood into the ventricles.
Therefore, the SA node is responsible for the initiation of impulses that stimulates heart contraction.
