Hello dear, I have gone through your post in which you have expressed your concerns regarding jumping rope and uterus dislocation. The Uterus is a very important organ of the female body. So nature has kept it secure & well protected with strong supports (called ligaments) inside the body. Dislocation of uterus(prolapse) occurs due to injury to these ligaments caused by trauma during complicated cases of child birth or gynecological surgeries. There are no chances of its dislocation on rope jumping. In fact jumping rope will help improving your fitness & keep you strong and active. There is no need to worry. Wishing you a Healthy Life. Take care.
