short laymen answer:
the diaphragm:a muscular partition separating the abdomin and thoracic cavities and the intercostal muscles.. they contract during inspiration. some neck muscles function in respiration and abdominal muscles assist to pull down the rib cage
long drawn out answer:
there are 7 muscles that assist in inhalation when running up the stairs and they are;
The lungs can be expanded and contracted in two ways:
by downward and upward movement of the diaphragm to lengthen or shorten the chest cavity, and by elevation and depression of the ribs to increase and decrease the anteroposterior diameter of the chest cavity.
Normal quiet breathing is accomplished almost entirely by the first method, that is, by movement of the diaphragm. During inspiration, contraction of the diaphragm pulls the lower surfaces of the lungs downward. Then, during expiration, the diaphragm simply relaxes, and the elastic recoil of the lungs, chest wall, and abdominal structures compresses the lungs and expels the air.
During heavy breathing, such that as in your question, however, the elastic forces are not powerful enough to cause the necessary rapid expiration, so that extra force is achieved mainly by contraction of the
Abdominal muscles, which pushes the abdominal contents upward against the bottom of the diaphragm, thereby compressing the lungs.
The second method for expanding the lungs is to raise the rib cage. This expands the lungs because, in the natural resting position, the ribs slant downward thus allowing the sternum to fall backward toward the vertebral column. But when the rib cage is elevated, the ribs project almost directly forward, so that the sternum also moves forward, away from the spine, making the anteroposterior thickness of the chest roughly 20 per cent greater during maximum inspiration than during expiration. Therefore, all the muscles that elevate the chest cage are classified as muscles of inspiration, and those muscles that depress the chest cage are classified as muscles of expiration.
The most important muscles that raise the rib cage are the
External intercostals, but others that help are the:
Sternocleidomastoid muscles, (promanant muscles of the neck) which lift upward on the sternum;
Anterior Serrati, muscles that in addition to other things elevate the rib cage; and
Scaleni, which lift the first two ribs.
The muscles that pull the rib cage downward during expiration are mainly
the
Abdominal recti, which have the powerful effect of pulling downward on
the lower ribs at the same time that they and other abdominal muscles also com-
press the abdominal contents upward against the diaphragm, and
Internal intercostals.
Running up stairs will build the quads, upper front of the legs and the calves from the pushing while running up on the toes. Over all tone will be the results. Adding the return of going down the stairs will balance the musle groups. going up will equal doing lunges.
The reason my heart beat changed is because when you exert your muscles they need extra oxygen so your heart beat increases to pump the requires oxygen amount to the muscles. So by running up and down stairs (or running on the spot as I have no stairs) you require more oxygen for your muscles. When you stop working your muscles they don't need the extra oxygen so your heart stops pumping the blood so fast around the body which then slows down your pulse to what it was to start with.
the longest time running up stairs is 10 min
running, climbing stairs
Your leg muscles work together to help you walk up stairs.
Mainly your leg muscles.
No, there is no official world record for running up the stairs of the Burj Khalifa. The Burj Khalifa has 2,909 stairs, but it is not a regular event or competition for individuals to attempt to climb the tower in record time.

Lower extremity needs most blood supply when climbing the stairs. This supply goes to the muscles.
sure it is excersice makes as much sense as running or joggin around a circular track
