Abstract

The purpose of the study is to explore the energy system contributions and determinants of performance in 400-meter military obstacle course (400m-MOC), and establish a model for predicting the performance in 400m-MOC. 50 male cadets participated in this study. Using portable gas analyzers and a blood lactate test, the energy system contributions were calculated during 400m-MOC test. Correlation analysis was conducted to ascertain the relationships between the performance of the 400m-MOC and the contributions of three different energy systems, as well as body morphology and various physical fitness components. A linear regression model was developed to predict the performance outcomes in 400m-MOC. The contributions of three different energy systems during 400m-MOC test were: phosphagen system (17.94±1.23%), glycolytic system (27.94±2.48%), and aerobic oxidative system (54.12±2.76%). Completion time for the 400m-MOC test correlates significantly with military service length, strength, BMI, speed, speed endurance, and aerobic endurance capability. The regression equation was formulated as: estimated 400m-MOC completion time=22.556 + 0.065 × 5000-meter running time-52.677 × (pull-up reps/body weight) + 0.582 × 400-meter running time. The 400m-MOC is primarily powered by the aerobic oxidative system, with aerobic endurance, upper body strength, and speed endurance being particularly crucial factors affecting its performance.

能量系统对400米军用障碍赛成绩的影响及决定因素。

本研究旨在探讨400米军事障碍赛（400m-MOC）中能量系统对成绩的贡献及其影响因素，并建立400m-MOC中成绩预测模型。50名男学员参加了本研究。利用便携式气体分析仪和血乳酸测试，计算了400m-MOC测试期间能量系统的贡献。通过相关分析，确定了400 - moc的表现与三种不同能量系统的贡献以及身体形态和各种体质成分之间的关系。建立了一个线性回归模型来预测400m-MOC的性能结果。在400m-MOC试验中，3种不同能量体系的贡献分别为：磷体系（17.94±1.23%）、糖酵解体系（27.94±2.48%）和有氧氧化体系（54.12±2.76%）。400m-MOC测试完成时间与服役期、力量、BMI、速度、速度耐力和有氧耐力能力显著相关。回归方程为：预计400m-MOC完成时间=22.556 + 0.065 × 5000米跑时间-52.677 ×（引体向上次数/体重）+ 0.582 × 400米跑时间。400m-MOC主要由有氧氧化系统提供动力，有氧耐力、上身力量和速度耐力是影响其性能的关键因素。

期刊介绍： The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence. Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
