Purpose
Considering that the decrease in strength can be observed with ageing and that muscular endurance and strength are essential factors for firefighting effectiveness in critical situations, the purpose of this study was to evaluate the Upper Body Strength and Lower Limb Power of Professional of Italian Firefighters of 229 Italian male firefighters (age 32 ± 8 years, height 177 ± 6 cm, weight 79 ± 9 kg, BMI 24.5 ± 2.4 kg/m2) and to compare the results in relation to the age (<30-year-old group; 31- to 35-year-old group; 36- to 40-year-old group; 41- to 45-year-old group; >45-year-old group).
Methods
Upper body strength (1RM bench press), lower limb power (counter movement jump—CMJ, and sprint ability—20 m) were analysed. Descriptive statistics and an Analysis of Variance (ANOVA) were applied to anthropometric and physical fitness values to assess significant difference between age groups. When a significant effect was found, Bonferroni’s post hoc analysis was used.
Results
Between age groups, anthropometric values showed an age effect (p < 0.05) for BMI with 34 % of all firefighters in overweight and high prevalence (52 %) in >45 compared to the other age group categories. Performances values showed differences for 1RM bench press [F
(4,223) = 6.17; p < 0.001], CMJ [F
(4,223) = 3.04; p < 0.05], 20 m [F
(4,224) = 8.47; p < 0.001] among age groups. A decrease of 12 % for bench press, 13 % for CMJ and 5 % for 20 m between <30 and >45-year-old groups was found.
Conclusions
Considering that the ability to produce strength and power movements are very important qualities to firefighters in each age, individuals and “job specific” training programs should be planned with functional work activities to improve neuromuscular function at any age.
