Wearable in-shoe pressure systems are widely used to measure GRF because they are not space restricted and allow for participants’ free movement (Fuchs et al., 2022). To facilitate clinical application, researchers attempted to develop a simplified system with a reduced number of sensors without impacting data validity (Fuchs et al., 2022). Previous study showed that the simplified in-shoe pressure system with 11 sensors was the optimal compromise between simplification and measurement performance (Fuchs et al., 2022). However, the study only validated eight layouts with different number of sensors (3-17 sensors). It was unclear whether there were better layouts with same of sensors (11 sensors). Furthermore, the validity of simplified in-shoe pressure system with 11 sensors in flat foot has not been verified.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S37 - S38"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44273376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every individual has a habitual motion path (HMP) defined by their bone structure, ligament laxity, muscular strength, and injury history (Trudeau et al., 2019). The rationale behind the HMP as an injury paradigm is that moving away from your HMP will increase joint loading in non-adapted areas, potentially increasing injury risk. Therefore, it is advantageous to decrease one’s deviation from their HMP. One tool for reducing movement deviations while running is footwear. This has been biologically supported, with research showing reductions in cartilage volume loss after a run in a shoe that decreased HMP deviations (Willwacher et al., 2020). A method (Run Signature 1.0) was developed to quantify one’s individual HMP and how much their joints move differently between habitual movements and when running, referred to as a deviation (Trudeau et al., 2019). One limitation of this method was the use of a single movement, the shallow squat, to quantify someone’s HMP. A second limitation was the calculation of a deviation on the run from the habitual motion at a single point in time, the point of maximum knee flexion during the stance phase. While this first method was a pivotal moment in quantifying human movement on an individual basis, we strive to advance this method by (1) capturing more habitual movements, and (2) use more than a single timepoint to quantify deviations.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S161 - S163"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44300417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, until recently, most studies quantified physiological and biomechanical variables in the VP4 alongside previously established running shoes. This approach has not enabled researchers to explain the specific effects of each unique feature of the shoe. In order to understand how and by how much specific feature of the VP4 affect running performance, one must first quantify, how and how much the specific feature of interest affects the biomechanics during running. In a second step one would have to determine the contributions of the mechanical adaptations to running performance using lab based running economy measurements.

This sex-based disparity is associated with differences in neuromuscular control, joint laxity, and anatomical alignment, altering kinetic and kinematic performance profiles (Decker et al., 2003). These differences widen with fatigue, furthering the risk of injury in females (Kernozek et al., 2007). Despite mechanical differences between sex, soccer footwear is designed for male users. With known sex differences in movement patterns and joint loading, it should not be assumed that females are able to withstand the same amount of traction as males. High traction footwear may exacerbate female susceptibility to torsional injury mechanisms, such as those of ACL injury, if rotational resistance exceeds ligament loading capacity (Butler et al., 2012). Cleat outsole properties, such as stud shape, are moderators of rotational resistance at the shoe-surface interface (Butler et al., 2012). However, the effect of stud shape on female mechanics remains unknown.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S199 - S200"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45437220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
