Our aim was to analyze the association between somatic maturation and alterations in metabolic syndrome (METs) risk and C-reactive protein (CRP), focusing on the effect of changes in trunk fat and sports practice. This was a longitudinal study with a one-year follow-up. The sample was composed of 139 adolescents (46 without sports participation and 93 young athletes), aged 10-17 years. As outcomes, we adopted CRP and METs risk (triglycerides, HDL-c, fasting glucose, and mean blood pressure). Somatic maturation was estimated using Mirwald's method. Structural equation models were used. Somatic maturation was not associated with sports practice, trunk fat, METs risk neither CRP. Sports practice was associated with a reduction in METs risk (β = -0.926; 95%CI:-1.773, -0.080) and reduction in trunk fat (-10.957; -19.630, -2.283), which was associated with increases in METs risk (0.020; 0.004, 0.036). In the CRP model, sports practice was associated with a reduction in trunk fat (-10.324; -18.637, -2.010), which in turn was associated with a reduction in CRP (0.007; 0.001, 0.013). Sports practice and lower trunk adiposity were associated with reductions in trunk fat, METs risk, and CRP through direct and indirect pathways. Our findings highlight the role of sports practice in attenuating the negative effect of trunk adiposity.
我们的目的是分析躯体成熟度与代谢综合征（METs）风险和 C 反应蛋白（CRP）变化之间的关系，重点关注躯干脂肪变化和运动实践的影响。这是一项为期一年的纵向研究。样本由 139 名青少年（46 名无运动参与和 93 名年轻运动员）组成，年龄在 10-17 岁之间。作为结果，我们采用 CRP 和 METs 风险（甘油三酯、HDL-c、空腹血糖和平均血压）。躯体成熟度采用 Mirwald 法估计。采用结构方程模型。躯体成熟度与运动实践、躯干脂肪、METs 风险和 CRP 均无相关性。运动实践与 METs 风险降低（β=−0.926；95%CI：-1.773，-0.080）和躯干脂肪减少（-10.957；-19.630，-2.283）相关，这与 METs 风险增加相关（0.020；0.004，0.036）。在 CRP 模型中，运动实践与躯干脂肪减少（-10.324；-18.637，-2.010）相关，这反过来又与 CRP 减少相关（0.007；0.001，0.013）。运动实践和较低的躯干脂肪含量与通过直接和间接途径降低躯干脂肪、METs 风险和 CRP 有关。我们的研究结果强调了运动实践在减轻躯干脂肪负面效应中的作用。
