Research on Health Promotion of MIddle aged and Elderly Working women

本研究的目的是：（1）评估中老年职业女性的饮食习惯，（2）观察腰椎骨密度，（3）阐明体育锻炼（游泳）对女性耐力和血脂谱的影响。结果表明，妇女的能量摄入量与对照组相近，而蛋白质和脂肪的摄入量高于对照组。他们的酒精摄入量不是这样的（大约一杯啤酒）。腰椎和股骨颈的骨密度略高于对照组。游泳训练1年后，每周参加游泳训练1.5次以上的妇女，其乳酸阈（LT）显著提高，而每周参加游泳训练1.5次以下的妇女，其LT无明显变化。女性的血液HDL胆固醇浓度在一年中没有变化，而每月参加培训超过6次的女性中观察到LDL胆固醇的增加显著减少。提示老年妇女每周参加1.5次以上的游泳训练可以改善耐力和血脂水平。

The purposes of this study were (1) to evaluate eating habit of working middle to elderly women, (2) to observe lumber bone mineral density, (3) to clarify effects of physical training (swimming) on endurance and blood lipid profile of the women. The results showed that energy intake of the women was similar to that of their counterparts, while protein and fat intake ws more than that of their counterpart. Their alcohol intake was not such (about a glass of beer). Bone mineral density of both lumber and femoral neck was a little bit higher than their counterparts. after the 1-year swimming training, Lactate threshold (LT) increased significantly for the women who participated the training more than 1.5 times a week, while no change in LT was observed for the member who participated the lesson less than 1.5 times a week. Blood HDL cholesterol concentration of the women did not change during the year, while significantly less increase in LDL cholesterol was observed i the women who participated the training more than 6 times a month. These results may suggest that endurance and blood lipid profile can be improved if the elderly women participate the swimming training more than 1.5 times a week.
