Summary
# Muscle Modes of the Equestrian Rider at Walk, Rising Trot and Canter The horse-rider dyad represents a complex biomechanical system, yet most research has focused solely on equine locomotion whilst largely neglecting the neuromuscular demands placed on the human partner. González Marc and Šarabon addressed this gap by comparing upper body, core and lower limb muscle activation patterns between six recreational riders and nine professional riders from the Spanish Classical School of Riding (Lipica) during walk, rising trot and canter, using surface electromyography synchronised with inertial motion capture of the horse's limbs. Principal component analysis revealed a striking distinction: novice riders demonstrated five distinct muscle activation modes including one reciprocal pattern characterised by simultaneous dorsal and ventral muscle contraction, whilst advanced riders exhibited only three modes with notably superior core engagement and intermuscular coordination. The hallmark of advanced horsemanship appears to be the ability to activate muscles contralaterally whilst avoiding reciprocal (antagonistic) dorsal-ventral patterns, combined with refined independent muscle control and the capacity to rapidly deactivate musculature during transitions. These findings have important implications for rider coaching and rehabilitation: training protocols might usefully emphasise core stability work and conscious suppression of reciprocal muscle patterns, whilst physiotherapists working with riders could employ this framework to identify compensatory movement strategies that impede performance or predispose to injury.

Practical Takeaways
- •Training should focus on developing independent muscle control and contralateral activation patterns rather than whole-body reciprocal movements, which distinguishes advanced from novice riders
- •Core stability and engagement are hallmarks of advanced horsemanship; coaching should emphasize core strength and coordination training
- •Novice riders can benefit from feedback targeting muscle efficiency and coordination, as their activation of more simultaneous muscle modes suggests unnecessary co-contraction that fatigues the rider
Key Findings
- •Advanced riders demonstrated 3 muscle modes compared to 5 modes in novice riders, indicating more efficient neuromuscular organization
- •Novice riders exhibited reciprocal dorsal-ventral muscle contraction patterns whereas advanced riders showed contralateral activation without reciprocal patterns
- •Advanced riders demonstrated significantly higher core muscle engagement and better intermuscular coordination than recreational riders
- •Advanced riders possessed the ability to activate individual muscles independently at varying levels and rapidly decrease overall muscle activity
