Dynamic load monitoring in skating

loadsol insole provides accurate measurements of the forces exerted by skaters during activities such as roller-ski skating. It can accurately capture temporal events and inner-cycle parameters, which are essential for understanding the dynamics of skating. By recording force data with high precision, these insoles offer valuable insights into the biomechanics of skating, enabling a detailed analysis of skating techniques and performance. This is crucial for both training and research purposes.

Pressure distribution measurement for skating utilizing pedar system

Skating is a fundamental movement in ice hockey and many sports. pedar is a gold standards tool to analyze the biomechanics of players. pedar used to measure plantar pressure distribution within the skate boot. The system equipped with instrumented insoles containing 99 pressure sensors, plays a crucial role in the study by providing detailed data on plantar force distribution and dynamics during skating. This information is key to understanding the biomechanical differences between high and low-caliber hockey players, particularly in analyzing their skating technique, force application, and overall performance.

As an example The Orthopedic Specialty Hospital (TOSH) of Salt Lake City performed a study examining kinetic and kinematic aspects of long track speed skating. In-skate pressures and forces were recorded using a pedar system.These data were collected simultaneously with a 3D motion capture system.

To collect in-skate pressures and forces, each Olympic skater was instrumented with a pair of pedar insoles and a telemetry (wireless) transmitter/receiver.Data collection began at the start position and continued until the skater completed just over one lap.The telemetered novel system delivered data at 50 Hz to a laptop computer while the skater circled the 400 meter oval at speeds over 15 m/s.  The pressure and force data were synchronized with the motion capture data.Together, these data can provide valuable information about athletic performance.The Orthopedic Specialty Hospital’s objective was to provide individual skater profiles that correlate 3D kinematics with in-skate pressure and force recordings. Analysis of these data have been used to develop a real-time testing and training tool for US Speed Skating coaches and athletes.
