Abstract

Introduction: Firefighting is amongst jobs that require high physical strength and high aerobic capacity. These are required because of the nature and the physical demands of the job. The maximum aerobic capacities of firefighters were investigated using the step test.

Methods: This cross-sectional descriptive-analytical study was conducted on 73 firefighters. At first, demographic information was collected by a questionnaire. Then, the step was built with adjustable height, for step testing, and using the Francis method, maximum aerobic capacity of the participants, was studied. The results of the questionnaire and step test were analyzed by the SPSS 16 software.

Results: maximum aerobic capacity of firefighters was calculated as 3.65 L/min and 47.4 mL/kgmin. Moreover, the results of statistical analysis revealed a significant relationship between body mass index and exercise, and maximum aerobic capacity (P ˂ 0.05). Also no significant relationship was found between maximum aerobic capacity, age, smoking and work-related fatigue (P > 0.05).

Conclusions: Studying the firefighters cardiorespiratory capacity, to reduce the probability of firefighters injuries is very important due to occupational sensitivity and having to perform difficult tasks under demanding circumstances. The results of this study showed that maximal oxygen uptake (vo2 max) and cardiopulmonary capacity of examined firefighters are greater than the minimum amount recommended by the international association of firefighters, which can be due to regular physical fitness programs conducted by the organization.

Abstract
Background and Objectives: Assessing the workability of employees is very important, and firefighting is one of the critical jobs. Therefore, the aim of this study was to evaluate the work ability index (WAI), and identify some effective factors among firefighters.
Methods: This cross-sectional study was carried out with participation of 101 firefighters in Zahedan, Iran in 2018. Subjects were included in the study by census method. Data were collected using a two-part questionnaire (demographic information and WAI items), and data analysis was performed using SPSS 24.
Results: The mean of age and work experience of the subjects were 34.18±6.70 and 8.47±6.79 years, respectively. Only 18 individuals (17.8%) were single, and most of them exercised at least once a week. The mean score of WAI was 44.33±3.56 and most of the subjects were in the excellent range. With increasing age and work experience, WAI decreased, and there was also a significant relationship between marital status and weekly exercise with WAI.
Conclusions: In general, the condition of the firefighters was favorable in terms of workability. However, due to the relationship between personal characteristics and WAI, it is necessary to adjust the duties of older people with more work experience.
