Technique-Dependent Relationship between Local Ski Bending Curvature, Roll Angle and Radial Force in Alpine Skiing

Autor: Christoph Thorwartl, Andreas Tschepp, Michael Lasshofer, Helmut Holzer, Martin Zirkl, Matthias Hammer, Barbara Stadlober, Thomas Stöggl

Publikováno v: Sensors, Vol 23, Iss 8, p 3997 (2023)

Skiing technique, and performance are impacted by the interplay between ski and snow. The resulting deformation characteristics of the ski, both temporally and segmentally, are indicative of the unique multi-faceted nature of this process. Recently,

Chapter 10 A life-long quest for biochemical regulation (Helmut Holzer, 1921–1997)

Autor: Karl Decker

Publisher Summary Helmut Holzer was born in the little town of Neuenburg on June 14, 1921. He was a pioneer in the area of enzyme regulation. He made his mark in classical biochemistry by the elucidation of the structure of active acetaldehyde as hyd

Validation of a Sensor-Based Dynamic Ski Deflection Measurement in the Lab and Proof-of-Concept Field Investigation

Autor: Christoph Thorwartl, Josef Kröll, Andreas Tschepp, Helmut Holzer, Wolfgang Teufl, Thomas Stöggl

Publikováno v: Sensors, Vol 22, Iss 15, p 5768 (2022)

Introduction: Ski deflection is a performance-relevant factor in alpine skiing and the segmental and temporal curvature characteristics (m−1) along the ski have lately received particular attention. Recently, we introduced a PyzoFlex® ski deflecti

Curvature Detection with an Optoelectronic Measurement System Using a Self-Made Calibration Profile

Autor: Christoph Thorwartl, Thomas Stöggl, Wolfgang Teufl, Helmut Holzer, Josef Kröll

Publikováno v: Sensors, Vol 22, Iss 1, p 51 (2021)

So far, no studies of material deformations (e.g., bending of sports equipment) have been performed to measure the curvature (w″) using an optoelectronic measurement system OMS. To test the accuracy of the w″ measurement with an OMS (Qualisys), a

A Novel Sensor Foil to Measure Ski Deflections: Development and Validation of a Curvature Model

Autor: Christoph Thorwartl, Josef Kröll, Andreas Tschepp, Philipp Schäffner, Helmut Holzer, Thomas Stöggl

Publikováno v: Sensors, Vol 21, Iss 14, p 4848 (2021)

The ski deflection with the associated temporal and segmental curvature variation can be considered as a performance-relevant factor in alpine skiing. Although some work on recording ski deflection is available, the segmental curvature among the ski

Classification of Alpine Skiing Styles Using GNSS and Inertial Measurement Units

Autor: Christina Neuwirth, Cory Snyder, Wolfgang Kremser, Richard Brunauer, Helmut Holzer, Thomas Stöggl

Publikováno v: Sensors, Vol 20, Iss 15, p 4232 (2020)

In alpine skiing, four commonly used turning styles are snowplow, snowplow-steering, drifting and carving. They differ significantly in speed, directional control and difficulty to execute. While they are visually distinguishable, data-driven classif
