The aim of this study was to find out how individually prescribed moderate physical training influences aerobic power and body weight in obese middle-aged men and women. 210 persons with poor physical fitness and body mass index (BMI) over 25 kg/m2 were accepted. Of these 169 persons were without regular medication and in this group 95 persons trained actively for the complete follow-up period of 17 months while 74 persons dropped out during the study. Maximal oxygen consumption was estimated indirectly before training and after 2, 5, 11 and 17 months of training. The exercise physiologist prescribed an individual training program, which was checked every six weeks. The most popular sports were walking and skiing. Initial aerobic power was poor in both sexes (3.1 +/- 0.1 l/min in men and 2.3 +/- 0.1 l/min in women, mean +/- SE). In the actively training group it increased significantly after two months and remained on this improved level for the rest of the observation period (total increase 14% in men and 11% in women). Initial BMI was 29.8 +/- 0.5 kg/m2 in men and 29.1 +/- 0.4 kg/m2 in women. The greatest change in body weight in the actively training group also took place during the first months. The mean decrease of body weight was 4.8 +/- 0.8 kg in men and 3.3 +/- 0.6 kg in women after 17 months. In conclusion, obese middle-aged men and women initially in poor physical condition can benefit from an individually prescribed training program resulting in significantly increased aerobic power and a minor loss of overweight.
本研究的目的是了解针对肥胖的中年男性和女性个体制定的适度体育锻炼如何影响有氧能力和体重。接受了210名身体健康状况不佳且体重指数（BMI）超过25kg/m²的人。其中169人未服用常规药物，在该组中，95人在为期17个月的整个随访期内积极锻炼，而74人在研究期间退出。在训练前以及训练2、5、11和17个月后间接估计最大耗氧量。运动生理学家制定了个性化的训练计划，每六周检查一次。最受欢迎的运动是步行和滑雪。两性的初始有氧能力都很差（男性为3.1±0.1l/min，女性为2.3±0.1l/min，平均值±标准误）。在积极训练组中，两个月后有氧能力显著提高，并在观察期的剩余时间内保持在这一改善水平（男性总体增加14%，女性增加11%）。男性的初始BMI为29.8±0.5kg/m²，女性为29.1±0.4kg/m²。积极训练组体重的最大变化也发生在最初几个月。17个月后，男性体重平均下降4.8±0.8kg，女性下降3.3±0.6kg。总之，最初身体状况不佳的肥胖中年男性和女性可以从个性化的训练计划中受益，该计划可显著提高有氧能力并轻微减轻超重。
