To examine neurocognitive and balance performance in recreational athletes, prior to and following a dual-task training intervention compared to single-task controls in order to assess the utility and feasibility of these interventions in the clinical setting.
Controlled laboratory study.
Thirty healthy, physically active recreational athletes (dual-task group = 15; single-task group = 15; age: 20.3 ± 1.9 years) completed neurocognitive and balance assessments before and after a four-week intervention. Sensory Organization Test composite score and ratio scores, Balance Error Scoring System total score, and nine CNS Vital Signs composite scores served as outcome measures. Mixed model analyses of variance were used to examine each measure.
The single-task group showed greater improvement for complex attention (F1,26 = 5.48, p = .027) following the training period. Both groups improved their performance on the complex attention domain (F1,26 = 6.73, p = .015), the Balance Error Scoring System score (F1,26 = 42.34, p < .001), and the Sensory Organization Test vestibular ratio score (F1,28 = 6.55, p = .016) following the intervention.
Our findings suggest combining cognitive and balance tasks as performed does not provide additional benefit to performing these tasks independently among healthy individuals, but appear to be feasible in this setting. Future research should examine integration of single-task and dual-task exercises for concussed patients.
在双任务训练干预前后，对业余运动员的神经认知和平衡能力进行检测，并与单任务对照组进行比较，以评估这些干预措施在临床环境中的实用性和可行性。
对照实验室研究。
30名健康、积极运动的业余运动员（双任务组 = 15人；单任务组 = 15人；年龄：20.3 ± 1.9岁）在为期四周的干预前后完成了神经认知和平衡评估。感觉组织测试综合评分和比率评分、平衡误差评分系统总分以及九项中枢神经系统生命体征综合评分作为结果指标。采用混合模型方差分析来检验各项指标。
训练期后，单任务组在复杂注意力方面有更大改善（F1,26 = 5.48，p = .027）。两组在干预后，复杂注意力领域的表现（F1,26 = 6.73，p = .015）、平衡误差评分系统得分（F1,26 = 42.34，p < .001）以及感觉组织测试前庭比率评分（F1,28 = 6.55，p = .016）均有所提高。
我们的研究结果表明，在健康个体中，将认知任务和平衡任务结合起来进行，并不会比单独执行这些任务带来额外的益处，但在这种情况下似乎是可行的。未来的研究应探讨单任务和双任务练习对脑震荡患者的整合情况。
