Physical efficiency in 184 spinners of a modern knitting plant has been examined by determining a maximum absorbtion of oxygen (VO2 max) using an indirect method of Astrand--Ryhming. A significant effect of age and consequently duration of employment on the decrease in physical efficiency level has been found. The distribution of efficiency index according to Astrand's classifications is not equal, which may result from a particular stereotype of motorial activity, especially non-occupational one.
通过采用阿斯特兰德-赖明间接法测定最大摄氧量（VO2 max），对一家现代针织厂的184名纺纱工的身体效率进行了检测。研究发现年龄以及由此导致的工作年限对身体效率水平的下降有显著影响。根据阿斯特兰德分类法得出的效率指数分布并不均匀，这可能是由于运动活动的特定模式，尤其是非职业性运动模式所致。
