To examine the association between aerobic performance and body composition changes by body mass index (BMI).
6-12 months' follow-up during military service.
Conscripts entering military service in 2005 in Sodankylä Jaeger Brigade (Finland).
945 men (19 years, SD 1 years).
Height, weight, waist circumference, BMI, and aerobic performance (Cooper test) were recorded. Body composition was measured by bioelectrical impedance analysis (BIA). The measured parameters were fat mass (FM), fat free mass (FFM), and visceral fat area (VFA). All the measurements were performed at the beginning and end of service.
On average, the military training period improved the running distance by 6.8% (169 m, p < 0.001) and the improvements were more pronounced in overweight (223.9 m/9.5%, p < 0.001) and obese (273.3 m/13.6%, p < 0.001) conscripts. A strong inverse correlation between aerobic performance and body composition changes was observed, especially for weight (r = -0.305, p < 0.001) and VFA (r = -0.465, p < 0.001). A significant association between aerobic performance and changes in weight (p < 0.001), waist circumference (p < 0.001), FM (p < 0.001), and VFA (p < 0.001) by BMI was detected. The associated decrease in weight, waist circumference, FM, and VFA with improved aerobic performance was more substantial between overweight and obese compared with normal-weight subjects.
Favourable changes in body composition are associated with improved aerobic performance during a physical training period such as military service. These findings are pronounced among overweight and obese men and can be applied at the population level in reducing obesity and co-morbidities.
通过体重指数（BMI）研究有氧能力与身体成分变化的相关性。
在服役期间进行 6-12 个月的随访。
2005 年在 Sodankylä Jaeger 旅（芬兰）入伍的新兵。
945 名男性（19 岁，标准差 1 岁）。
记录身高、体重、腰围、BMI 和有氧能力（库珀测试）。身体成分通过生物电阻抗分析（BIA）进行测量。所测量的参数包括脂肪量（FM）、去脂体重（FFM）和内脏脂肪面积（VFA）。所有测量均在服役开始和结束时进行。
平均而言，军事训练期使跑步距离提高了 6.8%（169 米，p<0.001），超重（223.9 米/9.5%，p<0.001）和肥胖（273.3 米/13.6%，p<0.001）新兵的改善更为明显。有氧能力与身体成分变化之间存在强烈的负相关关系，尤其是体重（r=-0.305，p<0.001）和 VFA（r=-0.465，p<0.001）。还发现有氧能力与体重变化（p<0.001）、腰围（p<0.001）、FM（p<0.001）和 VFA（p<0.001）变化之间存在显著关联，这与 BMI 有关。在超重和肥胖人群中，与正常体重人群相比，有氧能力改善与体重、腰围、FM 和 VFA 的相关下降更为明显。
在军事服役等身体训练期间，身体成分的有利变化与有氧能力的提高相关。这些发现对超重和肥胖男性更为明显，可应用于人群水平以减少肥胖和合并症。
