Neuromuscular strategies contributing to faster multidirectional agility performance

Area of Science:

• Biomechanics
• Sports Science
• Neuromuscular Physiology

Background:

• Agility is crucial in sports like basketball.
• Understanding neuromuscular strategies can optimize performance.
• Elite female athletes' specific adaptations require investigation.

Purpose of the Study:

• Determine neuromuscular strategy differences between faster and slower agility.
• Compare muscle activation strategies during sequential agility movements.
• Identify biomechanical factors influencing agility performance in female basketball players.

Main Methods:

• Recruited elite female basketball players.
• Measured quadriceps muscle cross-sectional area via ultrasound.
• Assessed muscle activation, rate of force development, and timing via reactive isometric mid-thigh pull.
• Analyzed muscle activation patterns during multidirectional agility tests.

Main Results:

• Faster agility correlated with higher pre-heel strike muscle activity.
• Greater anterior muscle activation during stance phase enhanced propulsive impulse.
• Differences between directional changes linked to processing speed and delayed refractory times, impacting muscle activation and deceleration.

Conclusions:

• Elite female basketball players exhibit distinct neuromuscular strategies for faster agility.
• Pre-strike and stance phase muscle activation patterns are key determinants of propulsive impulse.
• Neuromuscular responses to sequential directional changes are influenced by processing speed and motor control.
