FIELD MEASURES OF STRENGTH AND FITNESS PREDICT FIREFIGHTER PERFORMANCE ON PHYSICALLY DEMANDING TASKS
研究测量消防学员在训练中的力量和耐力，发现力量是预测消防任务表现的主要因素，加入有氧能力可提高预测准确性，并验证了力量和耐力的构念效度。
Recruits from 9 consecutive fire academy classes were assessed on a battery of strength and endurance measures at Weeks 1, 7, and 14 of training. Regression analyses using Week 1 measures indicated that strength variables were the primary predictors of performance on physically demanding firefighting tasks assessed at the completion of training. Incremental validity was obtained with the addition of aerobic capacity, which produced more accurate performance distinctions among recruits with high strength levels. Results showed predictive validity and linearity throughout the upper range of strength and endurance levels, but evidence of an increased drop‐off in performance for recruits with strength levels below the male 25th percentile. Structural equation modeling, a more powerful and comprehensive approach to validation than traditional regression, provided strong support for the construct validity of general strength and endurance as predictors of firefighter performance on physically demanding fire suppression and rescue tasks.
