Document Summary
Exercise results in mechanical force which cause strength increase in some skeletal body regions. Osteoblasts make and let got of collagen that are made into fibers to build bone matrix. Bone matrix becomes strong with solid minerals. Specificity of loading- exercise that target one muscle or muscle group. Program variation- exercises should vary in order to benefit different body parts at once and increase bone strength. Injury is result of too much intensity/ volume on tissue. Tissue damage possible though one workout or multiple workouts. Happens on bone"s periosteum and trabecular bone (thin and internal) Trabecular bone acts faster than cortical bone. Collagen deposit know up to 12 weeks. Osteoporosis- diseases due to low bone mineral density. Bone mineral density is most built during early adult years. Body tolerates high level exercise at young age. Structural exercise- workout that involves heavy loads that target different areas of body. Mechanical force applied to spine and hips.
