Exploring predictive ability of fitness test data relative to fire academy graduation in trainees: Practical applications for physical training

International Journal of Exercise Science 15(4): 1274-1294, 2022. This study investigated the predictive abilities of fitness tests relative to academy graduation in firefighter trainees. Archival fitness test data from 305 trainees were analyzed, including: Illinois agility test (IAT); push-ups; pull-ups; leg tucks; multistage fitness test; 4.54-kg backwards overhead medicine ball throw (BOMBT); 10-repetition maximum deadlift; and a 91.44-m farmers carry with 18-kg kettlebells. Within the department, trainees were allocated points for each test. Trainees were split into graduated (245 males, 16 females) or released (29 males, 15 females) groups. Independent samples t-tests and effect sizes calculated between-group fitness test differences (raw and scaled points). To provide a binary definition for the sensitivity/specificity analysis, trainees were defined as those scoring 60+ points for a test, and those scoring 0 points. For each test, the binary result (graduated/released) was plotted against the trainee’s test performance (60+ Points/0 Points). Receiver operating curves were plotted for each fitness test, and the area under the curve (AUC) determined accuracy. Trainees who graduated performed more push-ups, pull-ups, and leg tucks than released trainees, and scored more points in all tests (p≤0.005; d=0.34-1.41). Pull-ups, BOMBT, leg tuck, and the farmer’s carry had high sensitivity (\u3e80% true positive rate); the IAT had high specificity (83.3% for the true negative rate). Metronome push-ups, BOMBT points, and total points had fair accuracy for predicting academy graduation (AUC=0.709-0.754). While the data demonstrated that trainees who graduated tended to have better total-body muscular strength, endurance, and power, fitness tests may not be appropriate as a sole predictor for academy graduation

Exploring Predictive Ability of Fitness Test Data Relative to Fire Academy Graduation in Trainees: Practical Applications for Physical Training

A Preliminary Comparison of Firefighter Candidates\u27 Biddle Physical Ability Test Performance and Success Based on Training Class Participation

International Journal of Exercise Science 15(4): 1627-1640, 2022. The Biddle Physical Ability Test (BPAT) was developed to identify candidates who possess the physical ability to become structural firefighters. The test must be completed in ≤ 9:34 min:s before a candidate is admitted to an academy. Some community colleges offer semester-long training classes for candidates. This study analyzed whether candidates who completed a training class could perform the BPAT more effectively. Retrospective analysis of 30 males and 2 females who attempted the BPAT was conducted. BPAT tasks were: dry and charged hose drag; halyard raise, roof walk, and attic crawl; roof ventilation and victim removal; ladder removal and carry; stair climb with hose bundle; crawling search and tower exit; stair climb with air bottles; hose hoist; and return to ground floor with air bottles. Independent samples t-tests or Mann-Whitney U tests (p \u3c 0.05) and effect sizes calculated BPAT time differences between candidates who completed a training class or not. Twenty-nine candidates passed the BPAT; 6 completed a training class. The 3 candidates (2 males, 1 female) who failed did not complete a class. There were no significant between-group differences in BPAT times (p = 0.054-0.829). There were moderate effects for faster roof ventilation and victim removal, ladder removal and carry, and hose hoist times for candidates who attended a class (d = 0.74-0.95). While training classes may not be necessary for all candidates, physically demanding BPAT tasks were finished faster by candidates who completed a class. For candidates who find the BPAT physicality difficult, participation in a task-specific fitness and skills class may prove beneficial

Differences in fitness between Firefighter trainee academy classes and normative percentile rankings

Fire academy training classes may have trainees with a range of different fitness capabilities. Documentation of trainee fitness could indicate the need for flexibility in physical training emphases. Therefore, data from six academy classes (males = 274; females = 31) were analyzed, including: Illinois agility test (IAT), push-ups, pull-ups, leg tucks, multistage fitness test, backwards overhead 4.54 kg medicine ball throw (BOMBT), 10-repetition maximum deadlift, and 18 kg kettlebell farmers carry. A one-way ANOVA, with the Bonferroni post hoc test, calculated between-class fitness differences. Normative fitness test data were produced via percentile ranks. Classes 5 and 6 had the most females (n = 15). Class 1 completed the IAT faster than all classes (p ≤ 0.009). Classes 1 and 4 had a further BOMBT distance than Classes 5 and 6, and Class 3 outperformed Class 6 (p ≤ 0.044). Class 4 completed more leg tucks than Class 5 (p = 0.047). Class 1 had a greater deadlift than Classes 3, 4, and 6, and Class 2 outperformed Classes 3–6 (p ≤ 0.036). Class 3 was slower in the farmers carry compared to all classes (p ≤ 0.002). Percentile rankings showed that most females (48–100%) were in the 0–29% rank. Staff should implement individualized programs where appropriate for trainees as cohort fitness differences exist. Female trainees may need targeted maximal strength and power development
