[QUOTE="bubbles, post: 2630023, member: 210601"] Hikers often complain of a painful swelling in their fingers after a long day hiking. Others have indicated that they no longer experience this problem if they use trekking poles. What is probably going on here? A) Blood is pooling in the extremities after being on their feet all day. Using poles helps generate the muscle contractions that return blood to the heart. B) This is probably a side effect of high altitude sickness. Using the poles works the lungs better. C) The circulation to the fingers is restricted to conserve energy. D) Too much blood is pumping through their extremities as they exert the energy to hike. Please help? [/QUOTE]
