The physical demands of firefighting require both cardiovascular and muscular fitness, which both decline with age. While much has been published on age-related changes among male firefighters (FFs), data on female FFs are lacking.
To describe cardiorespiratory fitness (CRF) and muscular fitness in a sample of female career FFs ranging in age from 25 to 60 years and determine whether ageing affects their achievement of the current recommended professional CRF standards of 12 metabolic equivalents (METs).
Data were collected on female FFs over an 11-year period. A cross-sectional analysis using one-way analysis of variance with Bonferroni post hoc comparisons was used to compare age groups.
There were 96 study participants. Maximum METs was significantly higher (P < 0.01) in the 25- to 34-year age group (14.6 ± 2.1) compared with the 35-44 age group (12.9 ± 2.0 METs) and the 45-54 age group (12.2 ± 1.8 METs, P < 0.001). While the mean values of all measured age groups met or exceeded the 12-MET profession standard, as many as one-third of FFs <45 years of age and 43% of FFs >45 years of age fell below the benchmark of 12 METs. Muscular fitness as measured by maximum number of push-ups, sit-ups and back endurance was not significantly different between age groups.
Fire departments should recognize and take steps to ensure all female FFs maintain CRF and muscular fitness throughout their careers.
消防工作对心血管和肌肉健康都有较高的要求,而这两者都会随着年龄的增长而下降。虽然已经有很多关于男性消防员年龄相关变化的研究,但关于女性消防员的数据却很少。
描述年龄在 25 至 60 岁之间的女性职业消防员的心肺功能(CRF)和肌肉力量,并确定年龄是否会影响她们达到当前推荐的 12 代谢当量(MET)的专业 CRF 标准。
在 11 年的时间里,对女性消防员进行了数据收集。使用单向方差分析和 Bonferroni 事后比较的方法对年龄组进行了比较。
共有 96 名研究参与者。25 至 34 岁年龄组的最大 MET 值(14.6 ± 2.1)明显高于 35-44 岁年龄组(12.9 ± 2.0 METs)和 45-54 岁年龄组(12.2 ± 1.8 METs,P < 0.001)。虽然所有测量年龄组的平均值都达到或超过了 12-MET 的职业标准,但仍有三分之一的 45 岁以下女性消防员和 43%的 45 岁以上女性消防员未达到 12 METs 的基准。通过最大俯卧撑次数、仰卧起坐次数和背部耐力来衡量的肌肉力量在不同年龄组之间没有显著差异。
消防部门应该认识到这一点,并采取措施确保所有女性消防员在整个职业生涯中保持心肺功能和肌肉力量。
