The human hip joint is a phenomenal piece of engineering; the pelvic bone forms a beam separating the left and right femur which join the hip bone either side via a spherical cup joint. The ball is at the top of the femur and the cup is either side of the pelvic bone; the spine joins the structure at the centre. This scope of movement and rotation allow us to walk, run, jump as the femur rotates in the hip socket. Problems arise as we age due to arthritis, loss of bone density, wear and tear and old sporting injuries and accidents which haunt us with their consequences as we head down the path of life.
As with most bone structural issues we may experience, it is even more necessary to exercise these joints. Very often as we exercise joints the supporting soft tissue both connective and muscle, support the joints easing the load and improving the lubricating and cushioning effects (use it or lose it).
A walk of just 30 minutes 3 times a week can make a significant difference to joint comfort; gardening and light work around the house an extra trip or two up and down steps and stairs may also be very beneficial.
Heavy lifting, running, jumping and shock loads of any sort should be avoided if you have joint issues as this may aggravate them.
