The aim was to assess dual- versus single-task training for motor performance and cognitive performance in adolescents. Two experiments were performed. In the first, 30 adolescents were randomized to three groups to determine the effect of dual-task difficulty on postural control: α-scaling and root mean square (RMS). In the second, 20 adolescents were randomized to two groups to determine the effect of dual-task practice to improve working memory. RMS in the post-test was lower than the pre-test in both dual-task groups, while α-scaling was lower in post-test than pre-test only in the high-difficulty dual-task group. A practice effect was observed on the percentage of correct answers only in the dual-task group (p = 0.035). Thus, dual-task training could enhance motor and cognitive performance more than single-task training.

双任务干预对青少年姿势控制和认知能力的影响。

目的是评估青少年运动能力和认知能力的双任务训练与单任务训练。进行了两个实验。首先，将30名青少年随机分为三组，以确定双重任务难度对姿势控制的影响：α缩放和均方根（RMS）。在第二阶段中，将20个青少年随机分为两组，以确定双重任务练习对改善工作记忆的效果。两个双任务组的测试后均方根值均低于预测试，而仅高难度双任务组的测试后均方根值均低于测试前。仅在双任务组中观察到了练习答案对正确答案的百分比的影响（p = 0.035）。因此，双任务训练比单任务训练更能增强运动和认知能力。
