The Effects Of Resistance Training And Protein Supplementation On Bone Mineral Density In Untrained Women, Jessica Smith Nov 2022

The Effects Of Resistance Training And Protein Supplementation On Bone Mineral Density In Untrained Women, Jessica Smith

International Journal of Exercise Science: Conference Proceedings

Peak bone mass has been found to plateau at approximately 30 years of age; therefore, is it important to develop a higher peak bone mass early in life. Resistance exercise has been shown to improve bone mineral density (BMD) based on a great enough strain and mechanical load to promote bone formation. Resistance exercise is known to stimulate muscle protein synthesis, which can thereby raise individual protein needs above the recommended daily allowance (RDA). Resistance training (RT) combined with a protein intake above the RDA (> 0.8 g/kg/day) may be superior in promoting greater changes in BMD compared to RT …
