This study's primary objective was to examine the differences in body composition, abdominal strength, absolute and relative power, handgrip strength, one repetition maximum for squat and bench press, and the maximum count of push-up and sit-up repetitions executed within a minute across different age cohorts of firefighters. Furthermore, this study aimed to evaluate the age-related differences in firefighters' completion times of six firefighting tasks. Eighty-four male volunteer firefighters (age 33.79 ± 6.97 years) were grouped into three age categories, 20-30 years, 31-40 years, and 41-50 years, and underwent the aforementioned evaluations. One-way analysis of variance (MANOVA) revealed that age exerts a statistically significant influence ( < 0.001) on body fat percentage, waist circumference, and waist-to-hip ratio. Furthermore, age significantly affected the overall time of the ability test ( < 0.001) and the duration required to accomplish each individual task ( < 0.001). Additionally, age significantly affected abdominal strength, relative power (as measured by the step test), and the maximum count of push-up and sit-up repetitions performed within a minute. These outcomes support earlier research indicating an age-associated decrement in physical fitness parameters among firefighters. It is recommended that firefighters prioritize maintaining strength and endurance of the abdominal muscles, upper body muscular endurance, and a healthy body weight. The emphasis on specific muscular groups is essential for improving task performance within this profession.
本研究的主要目的是考察不同年龄组消防员在身体成分、腹部力量、绝对和相对力量、握力、深蹲和卧推的一次最大重复次数,以及一分钟内俯卧撑和仰卧起坐的最大重复次数方面的差异。此外,本研究旨在评估消防员完成六项灭火任务的时间与年龄相关的差异。84名男性志愿消防员(年龄33.79±6.97岁)被分为三个年龄组,20 - 30岁、31 - 40岁和41 - 50岁,并接受了上述评估。单因素方差分析(MANOVA)显示,年龄对体脂百分比、腰围和腰臀比具有统计学上的显著影响(<0.001)。此外,年龄对能力测试的总时间(<0.001)以及完成每项单独任务所需的时间(<0.001)有显著影响。此外,年龄对腹部力量、相对力量(通过台阶测试测量)以及一分钟内俯卧撑和仰卧起坐的最大重复次数有显著影响。这些结果支持了早期的研究,表明消防员的体能参数存在与年龄相关的下降。建议消防员优先保持腹部肌肉的力量和耐力、上身肌肉耐力以及健康的体重。对特定肌肉群的重视对于提高该职业的任务表现至关重要。
