Document Summary
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. Perichondrium is vacularized how water is transported. 80% made up of water endure great stress. External capsule cover soft organs protection. 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. 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. Strength training- results in higher cross sectional area of muscles that are used. Uses type 2 fibers more than type 1.
