Almstedt, HC, Canepa, JA, Ramirez, DA, and Shoepe, TC. Changes in bone mineral density response to 24 weeks of resistance training college-age men women. J Strength Cond Res 25(4): 1098-1103, 2011-Osteoporosis is a chronic disease major public health concern. Characterized by low mass increasing risk for fracture, osteoporosis occurs greater extent Resistance mode exercise that can be used build peak during youth, thereby preventing later life. Our aim was evaluate the effectiveness protocol designed apply loads hip spine We recruited recreationally active (n = 12) women 12), ages 18-23. An additional 10 participants (5 men, 5 women) served as controls. Volunteers completed questionnaires assess history, physical activity, dietary intake, menstrual history. The program performed weeks, on 3 nonconsecutive days per week, including exercises upper, lower, core musculature, marked an undulating periodization varying between 67 95% 1 repetition maximum (1RM) multijoint bench press, squats, deadlifts. Dual energy X-ray absorptiometry (Hologic Explorer, Waltham, MA, USA) (BMD, g·cm−2). A 2-tailed analysis covariance, controlling body index, revealed comparison women, had significantly increases BMD at lateral femoral neck. Male exercisers were found increase 2.7-7.7%, whereas percent change ranged from −0.8 1.5%, depending site. Both male female controls demonstrated about 1% any Results indicate training, squat deadlift exercises, effective young healthy men. Similar benefits not derived who followed same protocol.
