Why you get shortness of breath when climbing stairs:
So what's the deal with shortness of breath after taking the steps? We talked to top experts to find out.What’s going on in your body when you run is different from what happens when you climb stairs, and it has to do with slow-twitch versus fast-twitch muscle fibers, explains, professor of exercise science at Western Michigan University and a certified exercise physiologist.
“The slow-twitch fiber is high in endurance and fatigue resistance but low in power and strength. While climbing stairsbe an endurance activity, to propel your body vertically takes more strength and power, thus requiring more fast-twitch fibers to be recruited to accomplish the task.” And if you're breaking a sweat, that doesn't mean you're out of shape. Fit people actually sweat sooner and longer than those who don't work out regularly. Sweating is your body’s way of cooling itself off, according to Wyatt. “If you are a fit person, the sweating response to aid in cooling the body is quicker and more prolonged when compared to an unfit person.”Running is a forward-motion activity, but you have to work against gravity to lift yourself up a flight of stairs.
