虽然经常报告身体活动的积极影响，但仍然存在关于这些活动的类型，强度，持续时间和频率的不确定性，这些活动对青年时期的骨量（重新）建模最有效。在阿姆斯特丹生长和健康纵向研究中，对182名男性和女性的13至29岁的日常身体活动和健身进行了监测。在平均年龄为28岁时，采用双能X线吸收法（DXA）测量三个部位的骨密度（BMD）：（腰椎BMD）、股骨颈（髋关节BMD）和桡骨远端（手腕骨密度），身体活动（PA）是从交叉检查活动访谈中估计的，考虑到过去3个月内的所有日常身体活动; PA采用两种不同的方法进行评分：（1）代谢体力活动评分（METPA），采用强度加权法（基础代谢率[MET]的倍数）和持续时间（每周分钟数）;（2）机械体力活动评分（MECHPA）（地面反作用力为身体质量的倍数），而与身体活动的频率和持续时间无关。身体健康通过神经运动健康测试（由六项力量、柔韧性和速度测试组成）和心肺健康（最大摄氧量）进行测量。在两个年龄段计算身体活动和健康评分：青春期（13-16岁）和成年期（21-27岁）。标准偏回归系数（经性别、生物学年龄、身体成分和钙摄入量校正）显示，（METPA和MECHPA）、青春期和青年期的神经运动适应性与腰椎BMD显著正相关（β = 0.11-0.40）和髋关节BMD（β = 0.18-0.26），在平均年龄28岁时测量。但心肺功能的情况并非如此。没有发现与手腕骨密度的显著相关性，手腕骨密度是一个与身体活动和健康关系不大的骨骼部位。结果表明，青少年期和青壮年期的日常体力活动与男性和女性28岁时腰椎和股骨颈的BMD显著相关。在青春期和青年期，只有神经运动健康而不是心肺健康与28岁男性和女性的BMD有关。(C)2000年，Elsevier Science Inc.

Although positive effects of physical activity are often reported, there are still uncertainties about the type, intensity, duration, and frequency of these activities that are most effective for (re)modeling bone mass during youth. In the Amsterdam Growth and Health Longitudinal Study, daily physical activity and fitness were monitored from age 13 to 29 years in a group of 182 males and females. At a mean age of 28 years, bone mineral density (BMD) was measured at three sites with dual X-ray absorptiometry (DXA): in the lumbar region (lumbar BMD), the femoral neck (hip BMD), and the distal radius (wrist BMD), Physical activity (PA) was estimated from a cross-check activity interview taking in consideration all daily physical activities during the last 3 months; PA was scored in two different ways: (1) metabolic physical activity score (METPA) by weighting the intensity (multiples of basic metabolic rate [METs]) and duration (minutes per week); and (2) mechanic physical activity score (MECHPA) by weighting the peak strain (ground reaction forces as multiples of body mass) irrespective of frequency and duration of the physical activities. Physical fitness was measured with a neuromotor fitness test (composite of six strength, flexibility, and speed tests) and as cardiopulmonary fitness (maximal oxygen uptake). The physical activity and fitness scores were calculated over two age periods: during adolescence (13-16 years) and during adulthood (21-27 years). The standardized regression coefficients (corrected for gender, biological age, body composition, and calcium intake) show that weight, physical activity (both METPA and MECHPA), and neuromotor fitness during adolescence and in young adulthood are significantly and positively related with the lumbar BMD (beta = 0.11-0.40) and hip BMD (beta = 0.18-0.26), measured at the mean age of 28 years. This was not the case for cardiorespiratory fitness. No significant correlations at all are found with wrist BMD, a bone site that is less involved in physical activity and fitness. It can be concluded that daily physical activity during adolescence and in the young adult period is significantly related to the BMD at the lumbar spine and femoral neck at age 28 of males and females. Only neuromotor fitness and not cardiopulmonary fitness during adolescence and young adulthood is related to the BMD of males and females at age 28 years. (C) 2000 by Elsevier Science Inc.
