OBJECTIVES
Explore the correlation between cardiorespiratory fitness (CRF) and execution function (EF) of Chinese Tibetan adolescents at high altitude (HA) areas.
DESIGN
A cross-sectional survey was used to study 1138 participants aged 13-18 (47.72% boys) at baseline.
METHODS
Lhasa (3650 m), Nagqu (4500 m), Qamdo (3500 m), and Nyingchi (3100 m) in China were chosen. CRF was measured by the 20 m shuttle run test (20mSRT) and a subsequent estimation of their maximal oxygen consumption (V̇O) was calculated using the Léger equations. The three core EFs (inhibition, working memory, and cognitive flexibility) were tested by a modified Eriksen flanker, N-back, and a more-odd shifting. The association between CRF and EF was explored by Pearson correlation, one-way ANOVA, and stratified regression.
RESULTS
The reaction time (RT) of 1-back, cognitive flexibility with V̇O showed a declining trend, (F = 34.475, 27.498, P < 0.01). Interestingly, 2-back RT went up and then went down with V̇O (F = 29.55, P < 0.01). After increasing V̇O as a variable, a stratified regression analysis with the RT for 1-back, 2-back, and cognitive flexibility showed that ΔR equaled 0.107 ms, 0.071 ms, and 0.091 ms, respectively (P < 0.01). With V̇O increased by 1 mL/kg/min, the RT of 1-back, 2-back, and cognitive flexibility shortened 14.697 ms, 15.689 ms, and 11.771 ms, respectively.
CONCLUSIONS
CRF was positively associated with working memory, and cognitive flexibility development among Chinese Tibetan adolescents living at HA areas, respectively.
目的
探讨中国藏族青少年在高海拔（HA）地区心肺功能（CRF）与执行功能（EF）的相关性。
设计
采用横断面调查研究，在基线时对 1138 名年龄在 13-18 岁（47.72%为男性）的参与者进行研究。
方法
选择中国拉萨（3650m）、那曲（4500m）、昌都（3500m）和林芝（3100m）。CRF 通过 20m 穿梭跑测试（20mSRT）测量，随后使用 Léger 方程计算最大摄氧量（V̇O）的估计值。采用改良的 Eriksen 侧翼、N-back 和更多奇数转移测试来测试三个核心 EF（抑制、工作记忆和认知灵活性）。通过 Pearson 相关、单向方差分析和分层回归探索 CRF 和 EF 之间的关联。
结果
1-back 的反应时间（RT）、认知灵活性与 V̇O 呈下降趋势（F=34.475，27.498，P<0.01）。有趣的是，2-back RT 随着 V̇O 的增加而先上升后下降（F=29.55，P<0.01）。在增加 V̇O 作为变量后，1-back、2-back 和认知灵活性的 RT 进行分层回归分析显示，ΔR 分别为 0.107 ms、0.071 ms 和 0.091 ms（P<0.01）。当 V̇O 增加 1 mL/kg/min 时，1-back、2-back 和认知灵活性的 RT 分别缩短 14.697 ms、15.689 ms 和 11.771 ms。
结论
CRF 与中国藏族青少年在高海拔地区的工作记忆和认知灵活性发展呈正相关。
