What is Ageing and Work - 1620a How to promote health and work ability of firefighters using computer-based assessment method of physical work capacity about?

Methods 378 pushing and pulling test sessions were organised. Forces were measured by means of a computerised dynamometer (200 Hz, 120 Kg scale). 3 health operators (OH) and 2 very trained technicians (T) moved 2 types of hospital beds carrying simulated loads of patients weighting 70, 90 and 110 Kg, on a maximum distance of 300 m. To assess the speed limit (1 m/second) compliance, a 20 m pushing test was repeated multiple times by each tester. The same 20 m test provided individual threshold to compute initial and sustained forces. Initial force was defined as value lying above the threshold, the hysteresis curve and only for coherent data. To compare the speed suggested by the methods with the real speed performed by operators, a 2 months analysis of the patient transportation recorded missions was carried out. Then the accumulated delay-times were estimated with reference to the mean travel time measured at the suggest speed. Results Initial forces resulted 43% (32%-112%) and sustained forces 37% (23%-101%) higher and statistically significant for OH compared to T. Increased speed saves only 25% (12%-56%) of the travel time, due to elevators waiting, doors opening etc. Conclusio
