PURPOSE To examine the associations of age, lifestyle and work-related factors, and particularly work engagement with the work ability index (WAI) and its sub-dimensions. METHODS Step-wise regression analysis with a sample of Finnish firefighters (n = 403) was used. The outcome variables were the WAI and its six sub-dimensions. The independent variables(More)
INTRODUCTION Firefighters must work on roofs, in smoky places, and on slippery surfaces while using fire-protective clothing and a self-contained breathing apparatus (SCBA), together termed "fire-protective equipment" (FPE). The aim of this study was to investigate the effects of FPE on the functional and postural balance abilities of younger and older(More)
The biomechanical load of a rescue-clearing task (lifting a power saw from the floor up to the ceiling level) was evaluated with six older (47 +/- 5 years) and seven younger firemen (32 +/- 2 years). The mean dynamic compressive force at the L5/SI disc was 5998 N for the older subjects and 6392 N for the younger subjects. The peak torques for the back and(More)
The job demands on physical work capacity and the frequency of the firefighting and rescue tasks were rated by 156 professional firefighters (age range, 22 to 54 years) who responded to a questionnaire. Smoke-diving requiring the use of personal protective equipment was considered to demand most aerobic power. The clearing of debris with heavy manual tools,(More)
A study was made of the appraisers' effect on the estimation of metabolic rate with the Edholm scale and a table of the ISO 7243 heat stress standard. The appraisers, five experienced and five inexperienced persons, estimated the metabolic rate of three different work tasks from videotapes. Analysis of variance indicated significant ( [Formula: see text] )(More)
While wearing a self-contained breathing apparatus and fire-protective clothing, 35 healthy firefighting students aged 19-27 years performed smoke-diving (entry into a smoke-filled room) during a simulated shipboard fire. The mean (+/- SD) ambient temperature inside the simulator was 119 +/- 12 degrees C, and the task lasted 17 +/- 4 min. All subjects were(More)
OBJECTIVE To investigate the change trajectories of positive and negative moods and their relationship to work ability, self-rated health, and life satisfaction in a three-wave 13-year follow-up study. METHODS The data, consisting of Finnish firefighters (n = 360), were collected via questionnaires in 1996, 1999, and 2009. RESULTS Four distinct mood(More)
OBJECTIVE The importance of balance abilities for firefighting and rescue work has already been recognized, but there are no valid balance tests available in the test batteries for the physical work capacity of firefighters. Moreover, few studies have examined the associations between balance and work ability in general. Valid work-related balance tests are(More)
PURPOSE Monitoring cardiovascular risk factors is important in health promotion among firefighters. The assessment of arterial stiffness (AS) may help to detect early signs of atherosclerosis. The aim of this study was to analyze associations between aerobic fitness, cognitive symptoms and cardio-ankle vascular index (CAVI) as a measure for AS among Finnish(More)
OBJECTIVE To investigate developmental paths in multisite musculoskeletal pain (MPS) and depressive symptoms (DPS) and the effects of job demands (JD), job resources (JR), optimism and health-related lifestyle on these paths. We expected to find four trajectories--Low Symptoms, High Pain, High Depression and High Symptoms--and hypothesised that high JDs,(More)
