This prospective investigation was done to evaluate five strength and fitness measurements and the subsequent occurrence of back injuries in 1652 firefighters for the years 1971 to 1974. The prospective measurements included flexibility, isometric lifting strength, bicycle ergometer exercise measurements of two-minute recovery heart rate, diastolic blood pressure at a heart rate of 160 beats per minute and watts of effort required to sustain heart rate at 160. Three fitness and conditioning groups were established by multivariate ranking and regression techniques (259 high, 266 low, and 1127 middle) and the subsequent back injuries were tabulated for the three groups. The results showed a graded and statistically significant protective effect for added levels of fitness and conditioning (least fit, 7.1% injured; middle fit, 3.2% jured; and most fit, 0.8% injured). It was concluded that physical fitness and conditioning of firefighters are preventive of back injuries and that further investigations are warranted to study other injuries and physical fitness in this physically active occupational group.
这项前瞻性调查旨在评估1971年至1974年间1652名消防员的五项力量和体能指标，以及随后背部受伤的情况。前瞻性测量包括柔韧性、等长举重力量、自行车测力计运动测量两分钟恢复心率、心率为160次/分钟时的舒张压以及将心率维持在160所需的努力瓦特数。通过多变量排序和回归技术建立了三个体能和训练组（259名高水平组、266名低水平组和1127名中等水平组），并将三组随后的背部受伤情况制成表格。结果显示，体能和训练水平的提高具有分级且具有统计学意义的保护作用（最不适合组，7.1%受伤；中等适合组，3.2%受伤；最适合组，0.8%受伤）。得出的结论是，消防员的体能和训练可预防背部受伤，并且有必要进行进一步调查，以研究这个体力活动职业群体中的其他伤害和体能情况。
