This study investigated the effects of perceived groove on cycling performance and explored underlying neuromuscular control mechanisms.
Repeated-measures design.
Twenty-four university students completed the cycling task under three conditions: metronome, low-groove music, and high-groove music. Each task included 3 min of low-torque and 3 min of high-torque cycling. Measurements included pedal cadence, pedal cadence variability, work output, and intermuscular coherence between the trunk and lower limbs.
In low-torque cycling, pedal cadence variability was significantly lower in metronome than in low-groove music and high-groove music; coherence areas (A) in the γ band for the erector spinae and soleus were significantly higher in high-groove music than in low-groove music (ps < 0.05). In high-torque cycling, pedal cadence was significantly higher in high-groove music than in low-groove music and metronome, and higher in low-groove music than in metronome, pedal cadence variability was significantly lower in high-groove music and metronome than in low-groove music, and work output was significantly higher in high-groove music than in low-groove music and metronome (ps < 0.05). The A values in the α and γ bands for the rectus abdominis and gastrocnemius lateralis and the erector spinae and gastrocnemius medialis and in the γ band for the erector spinae and gastrocnemius lateralis were significantly higher in high-groove music than in low-groove music (ps < 0.05).
Perceived groove during high-torque cycling increased pedal cadence and work output, potentially due to increased cortical and subcortical drive shared between trunk and lower limb muscles.
本研究调查了感知节奏对骑行表现的影响,并探索其潜在的神经肌肉控制机制。
重复测量设计。
24名大学生在三种条件下完成骑行任务:节拍器、低节奏音乐和高节奏音乐。每个任务包括3分钟的低扭矩骑行和3分钟的高扭矩骑行。测量指标包括踏板节奏、踏板节奏变异性、功输出以及躯干和下肢之间的肌间协调性。
在低扭矩骑行中,节拍器条件下的踏板节奏变异性显著低于低节奏音乐和高节奏音乐条件;竖脊肌和比目鱼肌在γ频段的相干面积(A)在高节奏音乐条件下显著高于低节奏音乐条件(p<0.05)。在高扭矩骑行中,高节奏音乐条件下的踏板节奏显著高于低节奏音乐和节拍器条件,低节奏音乐条件下的踏板节奏高于节拍器条件;高节奏音乐和节拍器条件下的踏板节奏变异性显著低于低节奏音乐条件,高节奏音乐条件下的功输出显著高于低节奏音乐和节拍器条件(p<0.05)。腹直肌和外侧腓肠肌、竖脊肌和内侧腓肠肌在α和γ频段的A值以及竖脊肌和外侧腓肠肌在γ频段的A值在高节奏音乐条件下显著高于低节奏音乐条件(p<0.05)。
高扭矩骑行过程中的感知节奏增加了踏板节奏和功输出,这可能是由于躯干和下肢肌肉之间共享的皮层和皮层下驱动增加所致。
