Pairing high-intensity interval training (HIIT) with motor skill acquisition may improve learning of some implicit motor sequences (albeit with some variability), but it is unclear if HIIT enhances learning of motor sequences. We asked whether a single bout of HIIT after non-musicians learned to play a piano melody promoted better retention of the melody than low-intensity interval training (LIIT). Further, we investigated whether HIIT facilitated transfer of learning to a new melody. We generated individualized exercise protocols by having participants ( = 25) with little musical training undergo a graded maximal exercise test (GXT) to determine their cardiorespiratory fitness (VO ) and maximum power output (W). In a subsequent session, participants practiced a piano melody (skill acquisition) and were randomly assigned to a single bout of HIIT or LIIT. Retention of the piano melody was tested 1 hour, 1 day, and 1 week after skill acquisition. We also evaluated transfer to learning a new melody 1 week after acquisition. Pitch and rhythm accuracy were analyzed with linear mixed-effects modeling. HIIT did not enhance sequence-specific retention of pitch or rhythmic elements of the piano melody, but there was modest evidence that HIIT facilitated transfer to learning a new melody. We tentatively conclude that HIIT enhances explicit, task-general motor consolidation.
将高强度间歇训练（HIIT）与运动技能习得相结合，可能会改善某些内隐运动序列的学习（尽管存在一定变异性），但尚不清楚HIIT是否能增强运动序列的学习。我们探讨了在非音乐专业人士学会弹奏一段钢琴旋律后，单次HIIT是否比低强度间歇训练（LIIT）能更好地保持该旋律。此外，我们还研究了HIIT是否有助于将学习迁移到新旋律上。我们通过让25名几乎没有音乐训练的参与者进行分级最大运动测试（GXT）来生成个性化运动方案，以确定他们的心肺适能（VO ）和最大功率输出（W）。在随后的一次训练中，参与者练习一段钢琴旋律（技能习得），并被随机分配到单次HIIT或LIIT组。在技能习得后1小时、1天和1周对钢琴旋律的保持情况进行测试。我们还在习得1周后评估了对学习新旋律的迁移情况。使用线性混合效应模型分析音高和节奏准确性。HIIT并未增强钢琴旋律音高或节奏元素的序列特异性保持，但有适度证据表明HIIT有助于迁移到学习新旋律上。我们初步得出结论，HIIT可增强明确的、任务通用的运动巩固。
