青春期是人体剧烈变化的时期，此外，参加体育运动被视为男性青少年运动员身体活动的主要形式。本研究的目的是研究在最大生长期间身体成分和骨组织的个体内变化，以及12个月参与运动的影响，与机械冲击相比。样本包括40名年龄为12.57 ± 0.37岁的男性青少年运动员（足球：n = 20;游泳：n = 20），随访12个月。测量身高和体质量，用DXA评估骨矿物质含量（BMC）、面骨矿物质密度（aBMD）、瘦软组织和脂肪组织。食物摄入量估计使用调查问卷和培训课程单独监测。重复测量ANOVA测试运动和12个月个体内变异之间的差异（时刻：TM 1，TM 2）。控制基线时身高的变化，重复进行全身和全身减去头部的aBMD分析。足球运动员完成了63 ± 31次训练（95 ± 47小时）。游泳运动员的相应值为248 ± 28次和390 ± 56小时。总体而言，aBMD作为因变量的分析证明了运动相关变化（F = 5.254，p < 0.01; η2 = 0.35）和12个月增量的显著影响，特别是在下肢（F = 97.238，p < 0.01; η2 = 0.85）。aBMD的相应平均值为SCCTM 1 = 0.885 g.cm−2，SWMTM 1 = 0.847 g.cm−2，SCCTM 2 = 0.939 g.cm−2，SWMTM 2 = 0.880。关于瘦软组织，个体内差异的影响幅度非常大（F = 223.043，p < 0.01; η2 = 0.92），运动间中度（F = 7.850，p < 0.01; η2 = 0.41）：SCCTM 1 = 30.6 kg，SWMTM1 = 34.9 kg，SCCTM 2 = 35.8 kg，SWMTM2 = 40.5 kg）。最后，d-cohen值报告足球运动员和游泳运动员之间aBMD个体内变化的百分比对于转子来说很大（d = 1.2;年增量：SCC = 8.1%，SWM = 3.6%）。青春期是瘦软组织和骨矿物质密度发生显著个体内变化的时期。随着训练经验的不断积累，我发现运动与机械冲击之间的平均差异越来越明显，尤其是在下肢。在线版本包含补充材料，可通过10.1186/s12887-022-03321-2获得。
Puberty is a period of intense changes in human body and, additionally, participation in sports is viewed as prominent form of physical activity among male adolescent athletes. The current study was aimed to examine the intra-individual changes in body composition and bone tissue during years of maximal growth and the effect of 12-month participation in sports contrasting in mechanical impact. The sample included 40 male adolescent athletes (soccer: n = 20; swimming: n = 20) aged 12.57 ± 0.37 years who were followed for 12 months. Stature and body mass were measured, bone mineral content (BMC), areal bone mineral density (aBMD), lean soft and fat tissues assessed using DXA. Food intake was estimated using a questionnaires and training sessions individually monitored. Repeated measures ANOVA tested the differences between sports and 12-month intra-individual variation (time moments: TM1, TM2). The analyses on aBMD for total body and total body less head were repeated controlling for variation in stature at baseline. Soccer players completed 63 ± 31 sessions (95 ± 47 h). Respective values for swimmers were 248 ± 28 sessions and 390 ± 56 h. In general, the analysis of aBMD as dependent variable evidenced significant effect of sport-associated variation (F = 5.254, p < 0.01; η2 = 0.35) and 12-month increments, particularly at lower limbs (F = 97.238, p < 0.01; η2 = 0.85). Respective mean values for aBMD were SCCTM1 = 0.885 g.cm−2, SWMTM1 = 0.847 g.cm−2, SCCTM2 = 0.939 g.cm−2, SWMTM2 = 0.880. Regarding the lean soft tissue, the magnitude of effects was very large for intra-individual variation (F = 223.043, p < 0.01; η2 = 0.92) and moderate between sports (F = 7.850, p < 0.01; η2 = 0.41): SCCTM1 = 30.6 kg, SWMTM1 = 34.9 kg, SCCTM2 = 35.8 kg, SWMTM2 = 40.5 kg). Finally, d-cohen values reporting percentage of intra-individual changes in aBMD between soccer players ad swimmers were large for the trochanter (d = 1.2; annual increments: SCC = 8.1%, SWM = 3.6%). Puberty appeared as a period of significant intra-individual changes in lean soft tissue and bone mineral density. With increasing accumulated training experience, mean difference between sports contrasting in mechanical impact tended to me more pronounced in particular at the lower limbs.
