[Physical efficiency of women employed in the knitting industry].
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.
