Abstract

Background

Motor function and weight status are components of physical fitness that have been implicated in childhood motor and cognitive development. The lateralized readiness potential (LRP), an index of motor planning and action, can provide context surrounding relationships between fitness and brain activity underlying cognitive and motor functions. This study evaluated the relationship between the LRP and motor skills, as well as associations between weight status and neural and behavioral motor functions.

Methods

Children aged 7–13 (n = 35) participated in a cross-sectional study, using the Movement Assessment Battery for Children 2nd edition (MABC-2) to assess balance, manual dexterity, and aiming/catching. The stimulus- (LRP-S) and response-locked (LRP-R) LRPs were elicited from a modified flanker task. Stepwise regressions tested the association between LRPs and MABC-2 components. Linear regressions were conducted to examine BMI and %Fat in relation to LRPs and MABC-2 components.

Results

Analyses revealed that LRP-S mean amplitude difference (β = 0.401, P = 0.042) and reaction time interference scores (β = 0.545, P = 0.004) were positively associated with balance, after adjusting for covariates. The LRP-S and interference scores did not predict other MABC-2 outcomes and LRP-R did not predict any MABC-2 components. Further, %Fat (β = −0.439, P = 0.044), not BMI (β = −0.364, P = 0.082), only predicted balance.

Conclusion

We found that changes in the LRP-S amplitude were positively associated with balance, and %Fat was negatively related to balance. This evidence is that fitness components such as weight status and coordination are related to neural markers of motor function which may be useful in intervention designs aimed to improve brain function via improvements in physical fitness and health behaviors.

运动前规划的神经电指数和肥胖与儿童平衡的选择性关系

背景运动功能和体重状况是体能的组成部分，与儿童的运动和认知发展息息相关。侧向准备潜能（LRP）是运动规划和动作的一项指标，可为体能与大脑活动之间的关系提供基础认知和运动功能的背景。本研究评估了 LRP 与运动技能之间的关系，以及体重状况与神经和行为运动功能之间的关联。方法7-13 岁的儿童（n = 35）参加了一项横断面研究，使用儿童运动评估电池第 2 版（MABC-2）评估平衡、手的灵活性和瞄准/捕捉。刺激锁定（LRP-S）和反应锁定（LRP-R）LRP是从一项改良的侧翼任务中激发出来的。逐步回归测试了 LRP 与 MABC-2 成分之间的关联。结果分析表明，在调整协变量后，LRP-S 平均振幅差（β = 0.401，P = 0.042）和反应时间干扰得分（β = 0.545，P = 0.004）与平衡呈正相关。LRP-S和干扰得分不能预测MABC-2的其他结果，LRP-R不能预测MABC-2的任何成分。此外，只有脂肪百分比（β = -0.439，P = 0.044）而非体重指数（β = -0.364，P = 0.082）能预测平衡。这些证据表明，体重状况和协调性等体能要素与运动功能的神经标记相关，这可能有助于旨在通过改善体能和健康行为来改善大脑功能的干预设计。

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
