Exercise Prevents Osteoporosis Essay -- Healthy Lifestyle Essay

DiSilvestro et al., 2007, conducted an 8-week study; examining increased micronutrient intake in young adult women would enhance exercise-induced changes in bone metabolism that could lower the risk of osteoporosis later in life. Subjects were 24 female students 18-24 years old that were overall healthy and assigned to either the PG (Placebo group, n=12) or MG (micronutrient group, n=12). Fasting blood and urine samples were taken before and after the 8-week study to determine changes in: 25-OH-vitamin D, parathyroid hormone (PTH), bone specific alkaline phosphatase (BAP), Urine deoxypyridinoline (DPD) and helical peptide (AHP). A resistance exercise program consisting of: (3 sets/8-12 reps) bench press, bicep curl, shoulder press, seated row, leg extensions, hamstring curl, (1 set/failure) calf raises and abdominal crunches were conducted 3 d/wk for the 8-week study.
