At the onset of a muscle contraction, the presence of calcium triggers the opening of the Na-K channels in the membrane. Potassium is a calcium inhibitor, so as the potassium flows out of the cell, it eventually reduces the presence of calcium. This causes the closure of the Na-K channel (negative feedback mechanism). In a hypokalemic state, the lack of sufficient K doesn't inhibit the calcium channel, and in turn doesn't properly terminate the muscle contraction at the cellular level.
Great question. Cardiovascular endurance is how efficiently you heart, blood vessels, and lungs to supply oxygen rich blood to working muscles during physical activity (aerobic activity like walking, running, cycling or playing a sport) for a prolonged period of time or for more than 90 seconds.
Hope this helps!
