有氧运动对“煤工尘肺”的影响

Influence of aerobic exercises on coal worker's pneumoconiosis

我国煤矿职业病防治近年来虽取得较大进展,但形势依然严峻。经常从事有氧运动,能使心脏总体积指增大,心脏出现增大的趋势,不仅在心脏容量和心室壁厚度上有所增加,而且心室腔也显著扩大,心室扩大有助于增加心室充盈量,提高心脏的功能储备。通过有氧运动,吸氧量明显增加,能有效增强心肺功能。

At present,China coal miner pneumoconiosis morbidity situation is serious,and prevention and control of the disease is grim.Engage in regular aerobic exercises,can make the total cardiac volume increasd and heart appear increasing trend,not only increase of the heart volume but also ventricular wall thickness.The ventricular cavity was significantly expanded,ventricular enlargement contributes to increased ventricular filling volume,improve cardiac functional reserve.Through the aerobic exercise,oxygen consumption increased significantly,can effectively improve the cardiopulmonary function.
