项目摘要

We evaluated effects of age and rowing on cardiovascular function, blood lipid-lipoprotein profile and muscle mass. Although older oarsmen possessed a lower Vo2max than the young oarsmen, they showed a Vo2max similar to that of the young sedentary men but a higher value than obtained from the older sedentary men. The index of risk factors for CHD in the older oarsmen (LDL-C/HDL-C) was lower than that in the sedentary older men. The results suggest that rowing is an appropriate type of exercise for the promotion of health.We also evaluated the effects of rowing on the morphology and function of the leg muscle in older people. The leg extensor muscle area (CSA) of the oarsmen was larger that that of the sedentary men. Also the bilateral leg extension power of the oarsmen was larger than that of the sedentary men. Thus, the leg extensor power per CSA was not different between the two groups. The results suggest that rowing prevents age-related muscle wasting and weakness.This study evaluated oxygen uptake (Vo2) and heart rate (HR) during ergometry rowing (combined arm and leg ; sitting exercise) and treadmill running (leg ; upright exercise) for older people. The HR was lower during ergometry rowing than during treadmill running at a blood lactate concentration of 4mM (151±4 bpm vs. 160±5 bpm) and at a maximal effort (171±7 bpm vs. 177±7 bpm). This was the case although the Vo2 was higher during ergometry rowing than during treadmill running both at a blood lactate concentration of 4mM (3.0±0.4 /min vs. 2.7±0.4 L/min) and at a maximal effort (3.4±0.4 L/min vs. 3.1±0.3 L/min). The results suggest that, in prescription of rowing for older people, the relation between HR and Vo2 for rowing and the attenuated HR response to rowing should be taken into consideration.

我们评估了年龄和划船对心血管功能、血脂-脂蛋白谱和肌肉质量的影响。虽然年长的桨手拥有较低的Vo 2 max比年轻的桨手，他们表现出Vo 2 max类似的年轻久坐的男人，但更高的价值比从老年人久坐的男人。老年赛艇运动员的冠心病危险因素指数（LDL-C/HDL-C）低于久坐的老年男性。结果表明，划船运动是一种适合于促进健康的运动，我们还评估了划船运动对老年人腿部肌肉形态和功能的影响。划桨运动员的腿部伸肌面积（CSA）大于久坐的男子。划桨运动员的双腿伸展力量也大于久坐者。因此，两组之间根据CSA的腿部伸肌力量没有差异。结果表明，划船防止年龄相关的肌肉消耗和weaken.This研究评估摄氧量（Vo 2）和心率（HR）在测力划船（结合手臂和腿;坐着锻炼）和跑步机运行（腿;直立锻炼）为老年人。在血乳酸浓度为4 mM（151±4 bpm vs. 160±5 bpm）和最大努力（171±7 bpm vs. 177±7 bpm）时，测力划船期间的HR低于跑步机跑步期间。尽管在血乳酸浓度为4 mM（3.0±0.4 /min vs. 2.7±0.4 L/min）和最大努力（3.4±0.4 L/min vs. 3.1±0.3 L/min）时，测力划船期间的Vo 2高于跑步机跑步期间，但情况确实如此。结果提示，在老年人划船运动处方中，应考虑划船运动的HR与Vo 2的关系以及划船运动的HR反应衰减。
