Field-based IMU/force-plate framework for tennis serve kinetic chain
Key Questions
What is the field-based framework for assessing the tennis serve kinetic chain?
The framework, published in Frontiers, uses IMUs and portable force plates to evaluate lower-upper body coordination during the tennis serve. It introduces new indices like KCEI, Coupling Ratio, and Coverage Index to quantify kinetic chain efficiency and measurement coverage.
How does this framework bridge the lab-practitioner gap in tennis?
It enables on-court quantitative assessments that align with wearable sensors and motion capture systems. This innovation supports practical analysis of serve mechanics and injury risk identification outside traditional lab settings.
What role does markerless motion capture play in this highlight?
Markerless motion capture derives mechanical work as a valid indicator of acute neuromuscular fatigue. It complements the IMU/force-plate framework by providing fatigue insights during serves.
Frontiers framework for lower-upper body assessment in serve (KCEI, Coupling Ratio, Coverage Index); on-court quant innovation bridges lab-practitioner gap, aligns with wearables/mocap for serve mechanics/injury ID. Complemented by new markerless fatigue hit.
