Evaluation of an Occupational Exercise Training Program for Firefighters: Mixed Methods Pilot Study (Preprint)

Abstract

Occupational exercise training programs can improve overall health and fitness in firefighters, but evidence beyond clinical and performance outcomes is needed before fire departments invest in and successfully adopt health promotion programs.

This mixed methods pilot study sought to pair clinical and performance outcomes with participants’ qualitative feedback (eg, participants’ enjoyment, lifestyle behavior changes, and team structure) with the goal of informing recommendations for future programs.

Professional firefighters participated in a 14-week occupational exercise training program with assessments conducted pre- and posttraining. Clinical outcomes included weight, BMI, body fat percentage, resting heart rate, systolic blood pressure, and diastolic blood pressure. Performance outcomes included the sharpened Romberg balance test, 1-repetition maximum leg press and bench press, graded exercise test (estimated VO_2max), knee range of motion, shoulder flexibility, and hamstring flexibility. Self-administered surveys (Short Form-36, International Physical Activity Questionnaire, Barriers Self-Efficacy Scale, and Barriers to Being Active Quiz) were completed. In 3 private focus groups of 3 to 4 participants, firefighters' experiences in the training program and their health behaviors were explored.

Male firefighters (n=14; age: mean 36.4, SD 2.6 years) completed 20 training sessions. There were no significant changes to weight (<i>P</i>=.20), BMI (<i>P</i>=.15), body fat percentage (<i>P</i>=.16), systolic blood pressure (<i>P</i>=.12), estimated VO_2max (<i>P</i>=.34), balance (<i>P</i>=.24), knee range of motion (left: <i>P</i>=.35; right: <i>P</i>=.31), or hamstring flexibility (<i>P</i>=.14). There was a significant decrease in diastolic blood pressure (<i>P</i>=.04) and significant increases in shoulder flexibility (<i>P</i>&lt;.001) and leg press 1-repetition maximum volume (<i>P</i>=.04). Participants reported improvements in overall health, endurance, flexibility, and mood as well as improvements to team environment and health behaviors around the station; however, there was a decline in overcoming barriers to physical activity.

A 14-week program of exercise training in firefighters elicited improvements in clinical, performance, and self-reported physical activity outcomes. This occupational exercise training program for firefighters increased time spent exercising, improved team building, and led to physical and mental health benefits. Results from this pilot study set a broad, informed, and meaningful foundation for future efforts to increase firefighter participation in occupational fitness programs.
