Roller Speed Skating Kinematics and Electromyographic Analysis: A Methodological Approach.

Area of Science:

• Biomechanics
• Sports Science
• Rehabilitation Medicine

Background:

• Roller speed skating lacks specific biomechanical protocols for athlete rehabilitation and performance enhancement.
• Existing protocols from similar sports like hockey and ice skating do not fully address the unique demands of roller speed skating.

Observation:

• A novel functional, kinematic, and electromyographic protocol was developed using a world champion roller speed skater.
• Data collection involved an inertial sensor, electromyographic probes on lower limbs, and high-definition video analysis.
• The protocol captured muscle activation, agonist/antagonist co-activation, and body accelerations.

Findings:

• Detailed electromyographic activity and muscle activation levels relative to maximum voluntary isometric contraction (MVIC) were recorded.
• Agonist/antagonist muscle co-activation patterns were analyzed.
• Three-dimensional body accelerations were quantified.

Implications:

• The developed protocol serves as a foundational tool for future research in roller speed skating biomechanics.
• Findings will inform physiotherapy interventions and sport-specific training programs for roller speed skaters.
• Future research will establish normative ranges through elite athlete analysis, aiding in the targeted treatment of common injuries like groin strains.
