Impact of Neural network-quantified musical groove on cyclists' joint coordination and muscle synergy: a repeated measures study.
Haojie Li, Xinyu Lin, Xie Wu
PMID 41204282WHAT IT FOUND
High-groove music increased hip-ankle and pelvis-trunk coordination and added a fifth muscle synergy pattern during high-torque cycling compared to low-groove music or metronome.
These findings suggest rhythmic auditory cues can refine neuromuscular control, but this was a lab study on healthy cyclists.
Key findings
01During high-torque riding, hip-ankle in-phase coordination was significantly higher in both high-groove and low-groove music conditions compared to the metronome control, with high-groove music showing significantly higher coordination than low-groove music.
02High-groove music significantly increased the total number of muscle synergy patterns compared to low-groove music, with clustering revealing a unique fifth synergy pattern in the high-groove condition involving the erector spinae and gastrocnemius lateralis.
03Pelvis-trunk in-phase coordination in the vertical plane was significantly higher during high-groove music compared to both low-groove music and the metronome control during high-torque riding.

What it does not show
The sample consisted of only 24 healthy university students, which limits generalizability to clinical populations or older adults. The study measured short-term effects of music on coordination and muscle synergy but did not assess actual cycling performance outcomes like power output, efficiency, or fatigue. Participants' familiarity with and personal preference for the selected pop songs were not controlled, which could influence groove perception and motor synchronization. Psychological states such as motivation and fatigue were not monitored, potentially confounding the motor control results. The metronome condition was not used for muscle synergy comparisons, limiting the ability to distinguish between general rhythmic entrainment and specific groove effects on neural control.
The easy way to misread this
Do not interpret the changes in muscle synergy patterns and joint coordination as evidence that high-groove music improves cycling performance or reduces injury risk. The study measured neuromuscular control strategies in a laboratory setting but did not record actual performance metrics like power output, efficiency, or fatigue, and the participants were healthy young adults, not patients or competitive athletes.
