This may be explained by the decreased peak dorsiflexion angle, increased Achilles tendon moment arm and reduced force requirement to move the ankle (Sobhani et al., 2015). Besides kinematic differences, changes in electromyography (EMG) data were also found (Hoitz et al., 2020). Previous studies showed that a certain amount of time is required for EMG to adapt while running (Mohr et al. 2022). However, since EMG data may also be associated with changes in joint velocities, it is still unknown if kinematic data also requires adaptation time for rocker footwear. It is of even greater importance for rocker shoe studies to investigate the kinematic adaptation due to the large change in outsole geometry from a conventional shoe.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S144 - S145"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45430613","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}

The typical boxer stance includes the boxer’s stance and fighting stance, which is asymmetrical. A boxing punch is the main offensive weapon that uses a throw of mass of the whole body in the direction of the punch. Only because of stability of the combat stance, with a relatively large area of support, effective blows are delivered by rotational movement of the torso, with the center of gravity moving from one leg to the other.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S171 - S173"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41817220","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}

A softer or looser boot could dissipate the transfer of power, resulting in less responsive turning. Boot flexion stiffness is affected by boot materials, user anthropometrics, and the skier’s boot closure preferences (Immler et al., 2019). As a result, boot fit is a critical component of performance. Tight-fitting boots result in high foot pressures, which can impair motor control and temperature regulation. In athletic shoes, alternative fit systems result in a more uniform pressure distribution under the foot, including lower peak pressures under the heel and toes (Harrison et al., 2021). Reduced pressure may alleviate symptoms of pain and coldness associated with ski boots (Fontanella et al., 2021), which could improve performance. Ski performance can be parameterized as a set of force attributes during carving turns; specifically, greater force on the downhill foot, force under the forefoot and rate of force development during turn initiation are associated with expert skiers relative to novices.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S97 - S98"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47945772","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}

The pressure generated in the shoe occurs on the plantar and dorsal area of foot depending on the various physical activity. This pressure occurs repeatedly during high-intensity activities and causes damage to skin tissue and deformation of the musculoskeletal system (Mei et al., 2014; Mey et al., 2018).

Here, we divide the human functions to be expanded into four: physical motor function, sensory perception function, cognitive analysis function, and communication function. Human Augmentation research can be divided into two: one is to enhance each human function, the other is to realise remoteness by connecting to cyberspace, or those that use cyberspace to remove various physical restrictions and expand the scale. Human augmentation research includes development of technologies related to wearable sensing technology that comprehends people and situations, human digital twin that instantly converts that data into human evaluation indicators, and intervenes with the results through VR (virtual reality)/AR (augmented reality), audiovisual presentation, and haptic presentation. In the keynote speech, I will introduce Human Augmentation systems with wearable-sensing, digital human modelling, and intervention for concrete applications, such as healthcare services and sports training. Through these Human Augmentation systems, physical and/or mental abilities were improved temporarily. Moreover, continuous intervention with Human Augmentation systems, human physical and/or mental abilities were improved permanently. In order to develop digital human models and intervention systems, it is required to estimate human functions and context from sensing data with artificial intelligence technologies. Here, both deep data that is detailed human functional data corrected in laboratories and big data corrected through actual business services are required. Therefore, the Human Augmentation Research Centre focuses on not only technologies on sensing, modelling, and intervention, but also on services and design. This research framework directs to Servitization, such as changing the business model from selling the Human Augmentation systems to provision of services using the systems. I will introduce a concrete project on servitization with Human Augmentation system in this keynote. Human Augmentation research also focuses on cyberspace. I will introduce case studies of skill training and remote care services using cyberspace (Metaverse). These services are realised remotely by utilising VR/AR technology. In Human Augmentation using cyberspace, it is important not only to value co-creation in the cyberspace (Metaverse) but also to value transfer to the real space (Universe). Namely, services with Human Augmentation systems should change the bodybuild of a user’s avatar in the Metaverse and the real body of the user in the Universe both.
