![]() Indeed, pressure insoles are placed inside the shoe and are thin and light. Pressure insoles are a useful measurement system to assess kinetic parameters during posture, gait or dynamic activities in field situations, since they have a minimal influence on the subject’s skill (e.g. These results suggest a differentiated role played by each foot in alpine skiing turns: the outside foot has an active role in the turning process, while the inside foot may only play a role in stability. ![]() Moreover, under the outside foot was significantly greater than under the inside foot.RelPTI under different foot regions of the outside foot revealed a global shift from forefoot loading during initiation phase, toward heel loading during steering2 phase, but this was dependent on the slope studied. three other phases), although such modifications were observable only on the outside foot. flat sections), and the turn phase (higher during steering2 vs. ![]() Results indicated that under the total foot surface differed significantly depending on the slope (higher in steep sections vs. Component of the averaged Ground Reaction Force normal to the ski’s surface(, /BW), and Pressure Time Integral relative to the entire foot surface (relPTI, %) parameters were calculated for each turn phases based on plantar pressure data. Turns were divided according to kinematic criteria into four consecutive phases: initiation, steering1, steering2 and completion both steering phases being separated by the gate passage. Runs were recorded synchronously using a video camera in the frontal plane and pressure insoles under both feet’s plantar surface. Eleven skiers performed one giant slalom course at race intensity. Moreover, the outside foot was divided into different plantar regions to see whether those parameters affected the plantar pressure distribution. Specifically, this study investigated how turn phases and slope steepness affected the whole foot normal GRF pattern while performing giant slalom turns in a race-like setting. ![]() The purpose of this study was to investigate the evolution of ground reaction force during alpine skiing turns.
