INTRODUCTION AND MOTIVATION
The use of inertial technologies in climbing enables the analysis of movement dynamics, impact forces and technique variability during ascent and falls.
To improve measurement accuracy in high-impact situations, the IMU system has been reconfigured to extend its acceleration range up to ±16g. This allows reliable recording of sudden movements such as falls and dynamic rope interactions.
RESULTS AND CONCLUSIONS
Controlled drop tests were carried out to analyze the behavior of different types of climbing ropes under repeated falls. Three rope types were evaluated (dynamic, static and safety), using a 20 kg mass equipped with an IMU dropped from a height of 2 m. Acceleration was recorded at 200 Hz and transmitted via Bluetooth for analysis.
The results show how impact forces evolve across consecutive falls, providing useful information about rope performance and contributing to the development of safer practices in climbing activities involving fall scenarios
