Fitness tends to decline, whereas body fat increases, with age, which could impact firefighter occupational performance later in their careers. Health and wellness program participation could reduce these age-related changes. Archival data from 270 firefighters (258 men and 12 women) from a health and wellness program were analyzed. Data included body mass index; body fat percentage (BF%); waist circumference (WC); waist-to-hip ratio (WHR); sit and reach; grip strength; absolute and relative predicted 1 repetition maximum (1RM) leg press; crunches; push-ups; and estimated maximal aerobic capacity (Vo2max). Firefighters were grouped by age ≤29 (n = 29); 30-34 (n = 44); 35-39 (n = 38); 40-44 (n = 39); 45-49 (n = 48); 50-54 (n = 42); and 55+ (n = 30) years. A univariate analysis of covariance, with sex as a covariate and Bonferroni's post hoc adjustment, determined between-group differences. Effect sizes (d) were calculated. Key results included that the 55+ group had higher BF% and WC compared with the 3 youngest groups (p ≤ 0.002; d = 0.86-1.08). The 50-54 group had higher BF% than the 30-34 group (p = 0.010; d = 0.77). The 55+ group had a greater WHR, lower grip strength, and completed fewer crunches and push-ups than most younger groups (p ≤ 0.05; d = 0.60-1.32). The 50-54 and 55+ groups had a lower 1RM leg press and ...o2max compared with the younger groups (p ≤ 0.009; d = 0.77-1.79). The program appeared generally effective, with limited differences in groups below 49 years of age. Greater disparities in fat mass and fitness tended to occur in the older groups (50-54, 55+ groups). The data highlighted that older firefighters were participating in the optional program, which could lead to better health outcomes. [ABSTRACT FROM AUTHOR] |
