The results indicated that the muscle strength and muscle endurance of middle-aged employees was systematically lower among those with high muscular load compared to those with low load at work.Īndersen LB, Henckel P (1987) Maximal voluntary isometric strength in Danish adolescents 16–19 years of age. Muscle strength and muscle endurance was, however, not a discriminating factor between the group classifications of static and dynamic work. No other statistically significant differences in muscle strength or muscle endurance between the high and low work load groups were found, although the high work load group had systematically the lowest muscle strength and muscle endurance in almost all comparisons. These differences in strength among women between the high and low load groups were statistically significant ( P < 0.05). The women with high intensity in static work had a grip strength of 86% of those with low intensity. The maximal isometric hand grip strength of women with a load classified as long duration of static or dynamic load on the hands at work was 86 and 88%, respectively of the strength of those with a load of short duration. According to the job analysis, the subjects were classified into groups with low or high muscular load at work. ![]() A job analysis was done with the AET method including the assessment of intensity, duration and type of muscular work of each subject. Isometric grip and trunk strength were measured on dynamometers, and dynamic muscle endurance by sit-ups. The mean age of the subjects was 52.0 ± 3.4 years. Muscle strength and muscle endurance in groups with different occupational muscular load was studied among 60 women and 69 men. ![]()
