Star Destroyers: Ship List. There were at least several tens of thousands of star destroyers in the Imperial Starfleet. A complete listing is therefore impossible. I do not pretend that this list even approaches comprehensive status; there are far too many references for any writer to pursue.
The pulse raiser is the first part of a warm-up and can be any activity which can be used to gradually increase the heart rate. Jogging is a good example because it requires no equipment at all and can begin at a very slow speed and gradually increase.Other good choices are cycling and skipping. Gradually lower heart rate. 2  Circulate blood and oxygen to muscles, restoring them to the condition they were in before exercise. 3  Reduce the risk of blood pooling by maintaining muscle action and heart rate to pump blood back to the heart. 4  Remove waste products such as lactic acid. 5  Reduce the risk of muscle soreness.
How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.Medications and some medical conditions may affect how fast your heart-rate is at rest and with exercise.ou can tell how fast your heart is beating (your heart rate) by feeling your pulse. Your heart-rate is the amount of times your heart beats in one minute.
