Background and Objectives: This study evaluated and compared the cognitive function (CF) and aerobic fitness (AF) of 15 normal-weight (NW) and 15 overweight (OW) children, aged 6−12 years. In addition, the relationship between CF and AF was evaluated. Materials and Methods: The ANAM4 battery was used to evaluate CF, and a constant treadmill walking exercise (6 km/h for 6 min) and a progressive treadmill exercise (modified Balke test) were used to assess pulmonary oxygen uptake (VO2). Results: The OW children displayed worse attention and visual tracking (88.95 ± 4.45% and 93.75 ± 3.16%), response inhibition (90.27 ± 1.54% and 93.67 ± 2%), and speed of processing (93.65 ± 1.5% and 94.4 ± 1.54%) than the NW children (p < 0.05). The VO2 max was higher and the time constant of VO2 kinetics was shorter in NW children (56.23 ± 3.53 mL/kg/min and 21.73 ± 1.57 s, respectively) than in OW children (45.84 ± 1.89 mL/kg/min and 33.46 ± 2.9 s, respectively; p < 0.05). Conclusion: The OW children aged 6−12 years demonstrated poorer CF and lower AF than their NW peers. An association between AF and CF indicators was identified in both groups.
本研究评估和比较了 15 名正常体重（NW）和 15 名超重（OW）儿童的认知功能（CF）和有氧适能（AF）。此外，还评估了 CF 与 AF 的关系。材料与方法：采用 ANAM4 电池评估 CF，采用恒定跑步机步行运动（6km/h 持续 6 分钟）和渐进式跑步机运动（改良 Balke 测试）评估肺摄氧量（VO2）。结果：OW 组儿童注意力和视觉追踪表现更差（88.95±4.45%和 93.75±3.16%），反应抑制能力更差（90.27±1.54%和 93.67±2%），速度加工能力更差（93.65±1.5%和 94.4±1.54%），而 NW 组儿童表现更好（p<0.05）。NW 组儿童的 VO2 max 更高，VO2 动力学时变的时间常数更短（分别为 56.23±3.53mL/kg/min和 21.73±1.57s），OW 组儿童则更低（分别为 45.84±1.89mL/kg/min和 33.46±2.9s；p<0.05）。结论：6-12 岁的 OW 儿童的 CF 比 NW 儿童差，AF 也较低。在两组儿童中均发现了 AF 和 CF 指标之间的相关性。
