Ben Adams Long and short term effects of exercise on the skeletal system Short term Increased Synovial Fluid Production Our bones and joints are avascular (without blood supply). To keep our joints healthy, stop our cartilage from drying out and keep our cartilage lubricated and nourished, our joints produce an oil-like substance called synovial fluid. Synovial fluid is produced by the synovial membrane within our joints and is a short term or acute response to exercise. This means that our joints require regular exercise to stay lubricated, nourished and healthy. Increased Joint Range of Movement Exercise increases the production of synovial fluid which keeps our joints lubricated and makes them supple (bend and move easily and gracefully). Synovial fluid production increases the range of movement available at your joints in the short term. Often, after long periods of immobility (long periods of time not moving), our joints “dry out” stiffen up and lose some of their movement range. Exercise increases the range of movement available at our joints as more lubricating synovial fluid is released into them. Mobility exercises such as arm circles and knee bends keep our joints supple by ensuring a steady supply of synovial fluid. Ben Adams Long Term Increased Bone Density Weight-bearing exercise such as strength training and running put stress through your bones. In response to this stress our bodies produce cells called osteoblasts (a cell that secretes the matrix for bone formation) which build new bone and makes our bones stronger and denser. Increased bone density can prevent a condition called osteoporosis ( a medical condition in which the bones become brittle and fragile from loss of tissue) which is the weakening of bone and an increased probability of suffering fractures. Osteoporosis is more common in older females but can affect either
