A firefighting simulation was developed in order to assess the physical work capacity of firefighters. The simulation consisted of eight common firefighting tasks, including walking with radiant heat for 3 min while wearing full personal protective equipment (PPE). Nine professional firefighters performed the test a total of three times with a 5 min rest interval between each session. The entire series of tests took approximately 30 min to complete (381 ± 30 s). Rectal temperatures were found to increase from 37.4 ± 0.3 o C to 38.5 ± 0.4 o C, while heart rates were found to increase from 92 ± 18 bpm to 185 ± 13 bpm during testing. Time to completion of the test drills and non-modified physical fitness values showed a significantly negative correlation (r = −0.728, p < 0.05). Firefighters who had longer periods of firefighting service had longer duration time and also recorded higher scores using an integrated scoring system of time to completion (TTC) and physiological strain index (PhSI). The results indicated that the determination of TTC alone can be a misrepresentation of capability, as it neglects to account for accumulated heat strain. The simulated firefighting test provided a useful insight into physical fitness level, but also the comprehensive work capacity of the firefighters when assessed based on TTC and PhSI.

“…The high level of cardiovascular diseases (CVD) and mortality in the firefighters depends on the interaction of several factors such as sympathetic activation [3,16], physical workload [41][42][43], heat [5,11,44], dehydration [11,12,22], inadequate physical activity [45,46], dietary habits [47][48][49][50], shift work [47,[51][52][53], smoke exposure [54,55], noise [56] and psychological stress [12-14, 57, 58].…”

Firefighters perform strenuous muscular works in hazardous environments and chaotic conditions, under time pressure and psychological stress. Various studies have shown high values of oxygen uptake, heart rate, blood lactate concentrations and salivary cortisol and A-Amylase in laboratory test, in real-life and simulated interventions of firefighters. These high values have been attributed to the combined effect of the metabolically active muscle, thermoregulatory strain and fatigue resulting from the protective gear and a self-contained breathing apparatus in addition to further supplementary overweight (i.e., lifting weights, rescuing victims). In order to protect health and safety of firefighters and victims during emergencies, high levels of cardiovascular endurance and strength in firefighters are strongly recommended. In fact, high levels of physical fitness showed to increase firefighters' work ability, safety and decreased risk of injury.

“…In some studies the measuring equipment was clumsy and uncomfortable; therefore it interfered with the subject's normal activities or it could not be worn for the whole work day (Abdelhamid & Everett, 1999;Abdelhamid & Everett, 2002;I. Åstrand, 1967;Elsner & Kolkhorst, 2008;Richmond et al, 2008). In other studies the techniques selected to evaluate the physical demands were suitable for only a small number of subjects or they could not monitor the subjects continuously (Myrtek et al, 1999;Perkiö-Mäkelä & Hentilä, 2005;Rodahl et al, 1974;Turpin-Legendre & Meyer, 2003).…”

“…Several authors focused their attention on workers in light and heavy manufacture industry, teachers and lifeguards (Durnin & Passmore, 1967;Myrtek, Fichtler, Strittmatter, & Brügner, 1999). Other studies focused on fishing activities (Biswas & Samanta, 2006;Rodahl, Vokac, Fugelli, Vaage, & Maehlum, 1974), iron and steel industry (Kang, Woo, & Shin, 2007), miners (Palenciano, Gonzalez, Santullano, Rodriguez, & Montoliu, 1996), firefighters (Elsner & Kolkhorst, 2008;Richmond, Rayson, Wilkinson, Carter, & Blacker, 2008), choker setters (Kirk & Sullman, 2001), and farmers (Perkiö-Mäkelä & Hentilä, 2005).

Safety issues impact construction workforce and industry, for example by generating extra costs and delays. Achieving planned levels of productivity is crucial for the overall success of a construction project. Despite improvements in equipment and workplace ergonomics, the construction industry is still characterized by physically demanding activities and stressful environments. Excessive physical strain on the workers leads to decreased productivity, inattentiveness, poor quality work, accidents, and injuries. Therefore, a Physical Demand Monitoring System (PDMS) able to assess physical strain through a combined analysis of workers' physiological parameters (e.g., heart rate) and environmental conditions (e.g., temperature) may be an important step towards better safety and productivity management. In previous studies of physiological demands in construction the instrumentation hindered the workers' activities. However, now less invasive technologies are available for this purpose. The scope of this project is to establish the framework of a PDMS able to operate in real construction situations.
