Opis:
Type A is widely treated as a risk of diseases (mostly coronary heart diseases) and stress, including occupational stress. The purpose of the study was to evaluate the efficiency of intervention in modifying Type A in 25 managers in comparison with 38 Type A controls, who did not participate in the intervention. Additionally, the usefulness of the intervention was analysed when reactivity, as a temperamental dimension of Type A participants, was taken into account. High reactivity of Type A persons was assumed here as the presumed cause of the negative consequences in their health and well-being. The results showed a significant reduction in stress-related emotional symptoms, like depression, anxiety, anger, self-esteem, positive affects due to the intervention. These changes with the reduction in work ambiguity were greater in high reactive Type As than in low reactive ones.

Opis:
The study determined physiological and psychophysical responses to fire fighters’ typical activities. Selfreported assessment of the most demanding fire fighting/rescue tasks were collected with a questionnaire. Then 19 voluntary fire fighters performed 3 simulated fire fighting/rescue tasks in protective clothing. Heart rate (HR), blood pressure and energy expenditure were measured; the rating of perceived exertion (RPE) was assessed with the Borg scale. The questionnaires showed that carrying out victims, fire suppression and resuscitation were classified as heavy load; climbing stairs with a hose as moderate load. According to RPE the subjects considered their effort during ladder climbing fairly light and only somewhat harder during stair climbing and carrying out injured people. The study demonstrated that typical fire fighting/rescue tasks were associated with high energy expenditure and imposed considerable cardiovascular stress. The Borg scale appeared not suitable for assessing perceived exertion in fire fighters during simulated tasks.

Opis:
The purpose of this study was to assess the effect of external load at varying hand positions on discomfort, and to provide a new classification of external load. An experiment was carried out in which 16 postures with an external load of 0, 1.5, 3 kg were tested. The postures were controlled by 2 independent variables of hand distance and hand height. The subjects were instructed to rate their perceived discomfort with magnitude estimation after holding a given posture for 1 min. Analysis of variance (ANOVA) exhibited that the main effects of the 3 independent variables were statistically significant for discomfort. Discomfort increased linearly with external load and hand distance. Hand height showed a quadratic relation with discomfort, which exhibited a slightly different trend from hand distance and external load. Based on the results, a new classification of external load was proposed with 3 classes grouped by perceived discomfort.
