What effect do you think a program of lifting weights would have on the bones of the skeleton? How would you design an experiment to test your prediction?

To review:

The effect of program of lifting weights would have on the bones of the skeleton. Design of an experiment to test prediction.

Introduction:

Bone contains osteocytes embedded in a collagen matrix hardened by mineral deposits. Osteoblasts secrete collagen and minerals for the extracellular matrix (ECM); osteoclasts remove minerals and recycle them into bloodstream. Vital at every age for healthy bones, Exercise is crucial for treatment and prevention of osteoporosis. Exercise improves bone health, and increases muscle strength, coordination, and balance, and lead to better overall health.

The program of lifting weights is dedicated to training of persons with, or at risk of metabolic diseases (osteoporosis, obesity, diabetes). The reduced bone strength and high propensity to fractures is called as osteoporosis. Anatomically and physiologically, muscle and bones are interconnected, differences in muscle mass and force explain most of the differences in bone mass and strength in both children and adults of any age. Ultimately, intervention aimed at increasing bone strength should be primarily focused at improving muscle force and power, not directly delivering mechanical loads on the skeleton. Program of lifting weights come under resistance training. Resistance training on a regular basis can be beneficial to people suffering from chronic joint pain such as arthritis...
