Objectives:
This study investigated the effects of perceived groove on cycling performance and explored underlying neuromuscular control mechanisms.
Design:
Repeated-measures design.
Methods:
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.
Results:
In low-torque cycling, pedal cadence variability was significantly lower in metronome than in low-groove music and high-groove music; coherence areas (AZ) 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 AZ 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).
Conclusions:
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.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:25Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
