【摘要】：目的探讨相同负荷强度的抗阻力量训练对青年和老年女性骨密度的影响。方法身高、体重相匹配的青年组(n=36)和老年组(n=34)进行16w躯干、上下肢的抗阻力量训练。测试受试者腰椎(L_2~L_4)、股骨近端(股骨颈、Ward三角区、大转子)骨密度,拉力和下肢肌力。结果 (1)(3)干预后青年组股骨颈、Ward三角区和腰椎(L_2~L_4)BMD和拉力显著增大(P0.05),大转子BMD无显著变化;老年组股骨颈、Ward三角区和腰椎(L_2~L_4)BMD、拉力和下肢肌力显著增大(P0.05),大转子BMD无显著变化。(2)拉力与腰椎(L_2~L_4)、股骨颈、Ward三角区和大转子BMD呈显著正相关(r=0.642、0.686、0.600、0.781)、下肢肌力与腰椎(L_2~L_4)和Ward三角区BMD呈显著正相关(r=0.526,r=0.619)。结论 16 w力量训练改善了青年和老年女性腰椎和股骨近端的骨密度且无年龄差异,但对大转子骨密度改善不显著。
[Abstract]:Objective to investigate the effect of resistance strength training with the same load intensity on bone mineral density (BMD) in young and elderly women. Resistance strength training of upper and lower extremities. Bone mineral density (BMD) of the proximal femur (femoral neck Ward triangle, trochanter) was measured. Results after the intervention, the femoral neck Ward Ward triangle area and the lumbar spine L2L 4 BMD and the tensile force of the young group increased significantly (P 0.05), but the BMD of the great trochanter did not change significantly. In the elderly group, there was a significant positive correlation between the tension and lower limb muscle strength and the BMD of the greater trochanter, and the L2 / L + L4 / L4 / L2 / L + T / L + T / L / L + T / T group. There was a significant positive correlation between the tensile strength and the L2 / L _ 4 / L _ 4 of the lumbar spine, r _ (0.642) ~ 0.6860.600 / 0.600 / 0.781A, the muscle strength of the lower extremity and the L2T / L4 / L _ 4) and the L2T / L _ 4 / L _ 4) and the L2T / L _ 4 / L _ 4 / L _ 4, respectively. There was a significant positive correlation between BMD and BMD in the Ward triangle. Conclusion the bone mineral density of lumbar vertebrae and proximal femur in young and aged women was improved by 16w strength training, and there was no age difference between them. But the bone mineral density of the trochanter was not improved significantly.
