项目摘要

The purpose of this study was to examine the effect of regular training on physical fitness of elderly persons. Our previous studies (1987,1988) have revealed that the physical fitness of elderly people gradually improved as the average life span extended but the significant reduction in physical fitness was observed over seventy years.In this year, twenty subjects (8 men and 12 women) between 65 and 80 years of age voluteered to train two days each week for six months (from May to November). The physical training in every week consisted two programs. Subjects participated one day in Program I : recreational ball games Involving mini-tennis and table tennis, and other day in Program II: endurance training involving bicycle ergometer exercise and treadmill walking. Before training period (pre-test), middle of training period (mid-test) and after six months of training (post-test), the subjects performed physical fitness test involving exhaustive test on a bicycle orgonoter so as to determine the limited work load. Tbo ECG and blood pressure were examined in detail during exhaustive test. V02max did not change between pretest and mid-test but significant increase occurred between pretest and post-test. It was considered that muscle power or flexibility might improve relatively rather than endurance capacity or agility. We concluded that exercise heart rate (160 beat per minute) and systolic blood pressure (200mmHg) could be an index for limited work load of elderly people, although their individual physical fitness was considerably different from each other. Furthermore it is desirable to examine ECG during exercise to observe PVC or S-T segment depression.

本研究旨在探讨定期运动对老年人体能的影响。我们在1987、1988年的研究中发现，老年人的身体素质随平均寿命的延长而逐渐提高，但在70岁以后，身体素质明显下降，本研究对20名65 ~ 80岁的老年人（男8名，女12名）进行了为期6个月（5 ~ 11月）的每周两天的锻炼。每周的体能训练包括两个项目。受试者参加了一天的程序I：休闲球类运动，包括迷你网球和乒乓球，和其他一天的程序II：耐力训练，包括自行车测力计运动和跑步机行走。在训练前（前测）、训练中期（中测）和训练六个月后（后测），分别进行体能测试，包括自行车运动员力竭测试，以确定极限工作负荷。在力竭试验中详细检查心电图和血压。V02 max在测试前和测试中没有变化，但在测试前和测试后显著增加。认为肌肉力量或柔韧性可能相对提高，而不是耐力或敏捷性。结论：运动心率（160次/min）和收缩压（200 mmHg）可作为老年人有限负荷工作的指标，但老年人个体体能差异较大。此外，在运动过程中检查ECG以观察PVC或S-T段压低是可取的。
