摘要

简介服兵役期间的体能和脑力训练负荷可能会很高。因此,根据体能评估结果量身定制的预调计划可以提高服兵役的准备程度,尤其是那些体能基线水平较低的人。本研究旨在调查自我评估的健康行为、体力活动和肌肉健康状况如何预测年轻男女军人的体能:方法:通过问卷调查了解服兵役前的人口统计学、健康行为和日常体育锻炼情况。之后,通过 12 分钟跑步、1 分钟俯卧撑和仰卧起坐测试评估服兵役期间的体能。下肢爆发力通过最大立定跳远进行研究。人体测量包括体重、身高和腰围:结果:客观测量的 12 分钟跑步距离的两个最强的个体预测因素是男性和女性的自我报告体育活动和身体准备情况。自我报告的体力活动、服兵役准备情况、久坐时间、教育程度、吸烟和身体人体测量共解释了男性 12 分钟跑步测试结果变异的 52%(R2=0.52,平均绝对百分比误差(MAPE)8.8%,平均绝对误差(MAE)207 米),而对女性的预测值较弱。在调整后的回归模型中加入肌肉健康结果进一步改善了模型,该模型解释了男性应征者 12 分钟跑步测试结果中 59% 的变异(R2=0.59,MAPE 7.8%,MAE 181 m):在本研究中,自我报告的体力活动、肌肉健康状况、服兵役的身体准备情况、久坐时间、教育程度、吸烟和身体人体测量指标对新兵耐力能力的测量结果预测不足。目前以问卷为基础的变量不能准确预测新兵的体能,因此既不适合实际用于入伍前的预调计划,也不适合入伍前的预选。

Aerobic fitness predicted by demographics, anthropometrics, health behaviour, physical activity and muscle fitness in male and female recruits entering military service.

Introduction: The physical and mental training load can be high during military service. Therefore, tailored preconditioning programmes based on assessment of physical fitness could increase readiness for military service, especially among those ones with lower baseline fitness level. The purpose of present study was to investigate how self-assessed health behaviour, physical activity and muscle fitness can predict physical fitness in young male and female military cohorts.

Methods: Demographics, health behaviour and daily physical activity preceding military service were surveyed by a questionnaire. Thereafter, physical fitness was assessed during the military service by the tests of 12 min running, 1 min push-ups and sit-ups. Explosive power of the lower extremities was studied by maximal standing long jump. Measurements of body anthropometry consisted of body mass, height, and waist circumference.

Results: The two strongest individual predictors of objectively measured running distance in 12 min were self-reported physical activity and physical readiness in both men and women. Self-reported physical activity, readiness for military service, sitting time, education, smoking and body anthropometrics together explained 52% of the variance in the 12 min running test result (R2=0.52, mean absolute percentage error (MAPE) 8.8%, mean absolute error (MAE) 207 m) in men, while for women the predictive values were weaker. Addition of muscle fitness results to the adjusted regression model further improved the model, which explained 59% of the variance in the 12 min running tests result of male conscripts (R2=0.59, MAPE 7.8%, MAE 181 m).

Conclusion: In the present study, self-reported physical activity, muscle fitness, physical readiness for military service, sitting time, education, smoking and body anthropometrics predicted inadequately the measured endurance capacity among recruits. The present questionnaire-based variables do not accurately predict physical fitness of recruits and thus, they are not either suitable for practical use for preconditioning programmes or preselection before entering the military service.
