Recently my dance partner and I have ventured into the acrobatic end of dance to expand our repertoire. We are both in our 40s and athletic builds. I am 160 lbs. She is 140 lbs.. The first injury happened to her. She dislocated a rib during a maneuver where I lift her body horizontally and move her around (you could actually see the rib sticking out of her back). After a month off from acrobatics, visits to the chiropractor and daily exercises, it was put back in place. It still pops, but the chiro recommended continuing unless it hurts. The other day we were trying another maneuver whereby she dangles upside down gripping my shoulder with one knee, then I lift her . . . . anyway, the following two days I have been experiencing a couple different types of pain associated with my hip area - pain in the rear of the join, and short sharp pains in the upper groin areas (close to where the femur connects to the pelvic bone). So I'm taking a few days off. We live in a dance center with many qualified people, and have spent months trying to engage coaches to help us out with aerial work, but it seems no one is interested or returns our calls. I guess they're too busy making $millions. So in the meantime we're left to work on our own. I'm interested to know if anyone has experienced similar problems from lifting people and what you did to prevent injuries? Thanks for any advice you can offer!
