Trail running has become popular and is characterized by running on rough terrain with positive and negative elevation changes throughout the course. Downhill running is associated with increased eccentric muscle contraction and increased peak tibial acceleration (Chu and Caldwell, 2004), which has been correlated with tibial stress fractures in runners (Milner et al., 2006). Although biomechanical differences during downhill running have been described, these effects have been mainly reported on treadmills, where the subjects typically run at a controlled speed. However, this is not a reality in trail running as the subjects change their pace due to various uphill and downhill slopes. To address this issue and to provide “realworld” data, inertial measurement units (IMUs) have been employed. Indeed, the literature has encouraged the use of IMU sensors to perform biomechanical analysis of running patterns in the natural environment (Reenalda et al., 2016). To improve running performance, running shoe technology such as the incorporation of increased longitudinal bending stiffness (LBS) and curved carbon-fiber plates has been adopted by the footwear industry. Although a carbon plate seemed not to influence the tibial acceleration in a previous study, this was conducted on the treadmill at a constant speed and only 1% of inclination (Kiesewetter et al., 2022). Purpose of the study
越野跑已经流行起来，其特点是在崎岖的地形上跑步，整个过程中都有正负海拔变化。下坡跑步会增加偏心肌收缩和胫骨加速峰值(Chu和Caldwell, 2004)，这与跑步者的胫骨应力性骨折有关(Milner等，2006)。虽然在下坡跑步时的生物力学差异已经被描述过，但这些影响主要是在跑步机上报道的，在跑步机上，受试者通常以受控的速度跑步。然而，这在越野跑中是不现实的，因为受试者会因各种上坡和下坡而改变他们的速度。为了解决这个问题并提供“真实世界”的数据，惯性测量单元(imu)已经被采用。事实上，文献鼓励使用IMU传感器对自然环境中的跑步模式进行生物力学分析(Reenalda et al.， 2016)。为了提高跑步性能，鞋类行业采用了诸如增加纵向弯曲刚度(LBS)和弯曲碳纤维板等跑鞋技术。虽然在先前的研究中，碳板似乎不会影响胫骨加速度，但这是在跑步机上以恒定速度进行的，只有1%的倾斜(Kiesewetter et al.， 2022)。研究目的

Running is one of the most popular leisure activities due to its low costs, easy accessibility and associated health benefits. Most of the runners are recreational runners who run at (very) slow speeds. Unfortunately, half of these runners develop a running related injury (RRI). These injuries are predominantly determined by the load that is exerted on the body. Whereas the internal load exerted on tissue level is difficult to quantify, external forces and kinematics are not. As such, ground reaction forces (GRFs) and joint moments are often used as operational measure to provide insights in this internal loading. Running style spatiotemporal defined by duty factor (DF; the product of contact time with stride frequency) and stride frequency (SF) determines the external loading that a runner experiences. Given that recreational runners show a high interindividual variation in DF and SF, establishing the relationship between these parameters themselves but also with external and internal load measures provide deeper understanding of how running style can be used to identify runners’ with a higher risk for the development of a RRI.

Slipping-related falls are a prevalent source of injuries that have driven the development of various experimental devices to assess the slip resistance of footwear products. These devices are useful for testing existing solutions and identifying the most suitable products for a specific use. During a slip event, the mechanical loadings undergone by the outsole material are generally strongly heterogeneous, leading to a coupling between the stud geometry and the material mechanical behaviour (Jones et al., 2018). Most of the previous studies emphasize the role of the viscoelastic properties on the slip resistance but the experiments are often performed using commercially available footwear products with a large range of outsoles geometry and materials; making the conclusion difficult to generalize. More specifically, the exact solicitations frequencies applied on the outsole are still unknown, hindering the identification of the targeted material properties for optimizing the slip resistance of the outsoles. Among the challenges to overcome to optimize the slip resistance of the shoes, finely identifying the aforementioned properties is a critical issue and requires isolating the contribution of the material from the geometry of the outsole.

Forefoot bending stiffness has been shown to influence both injury and performance. Regarding performance, specifically sprinting, research has shown increased bending stiffness resulted in improved performance (Stefanyshyn and Fusco, 2004). However, there is evidence suggesting increased bending stiffness has detrimental effects on performance during the acceleration phase of sprinting (Willwacher et al., 2016). Previous research has suggested a carbon fibre plate with a non-linear bending stiffness profile might negate the detrimental effects during sprint acceleration (Wannop et al., 2017).

The emergence of advanced footwear technology (AFT) has dramatically altered the world of distance running. Shoes featuring precise combinations of materials and geometry, centering around a stiff curved carbon fibre plate with a thick midsole comprised of highly compliant and resilient foam, have been shown to influence running economy. For instance, the Nike Vaporfly 4% was so named because of findings by Hoogkamer et al. (2018) that showed a 4% improvement in running economy. Further, the 4% improvement in running economy has resulted in a 2.3% improvement in elite marathon performance in men and women (Senefeld et al., 2021). However, previous literature has not been able to distinguish between shoe features while comparing across different shoes leaving the magnitude and mechanism behind the improvement in running performance unclear.

Minimal shoes and shoes incorporating advanced technology are at opposite ends of the spectrum in several regards, such as their degree of minimalism, cushioning, and heel height. Yet, both shoes can appeal to runners in terms of potential for injury risk reduction or performance enhancement. In recent years, technologically enhanced shoes have drawn attention in media and science. Much of the research focuses on highly trained runners and treadmills; but most runners are recreational and run outdoors. This discrepancy limits our ability to make informed decisions and evidence-based shoe recommendations. In addition to injury risk and performance considerations, comfort is a key factor in shoe selection, but is multifactorial in nature. Limited data exist on what factors affect shoe selection and comfort in recreational runners.

A recent RCT study has shown that a low-friction lateral patches (Spraino#) prevents 53% of severe ankle injuries in division level athletes and decrease injury time by two-thirds (Lysdal et al., 2021). This patch solution has been developed into a shoe with Spraino elements built in. This makes it an attractive method in primary prevention, with no hassle for the athlete, and for secondary prevention, where first line methods such as taping and rehabilitation, have poor adherence. The shoe integration also allows the solution the fine tune positive effects and avoid adverse effects. The shoes were constructed not to impact lateral forefoot traction in non-injury situations. In shoe research, the 100mm VAS scale has been used as reliable measure of comfort and we therefore recorded perception of stability using this scale (Menz & Bonanno, 2021). Movements such as side hop and jumping with a lateral direction creates a lateral centre of pressure and can cause lateral ankle sprains, making them relevant for testing lateral shoe friction perception.

The foot ankle system is an important component of human locomotion. The footwear mechanical properties such as insole stiffness was reported to influence foot ankle biomechanical patterns and locomotion performance (Ray & Takahashi, 2020; Stefanyshyn & Fusco, 2004). The foot segment can be regarded as the triceps surae muscles’ lever arm during locomotion (Ortega et al., 2021). Increasing footwear bending stiffness was reported to move the centre of pressure (COP) more anterior (Takahashi et al., 2016), and the ground reaction force gear ratio would tend to increase as well (Ortega et al., 2021). While most of the studies were focusing on running gait analysis. Additionally, the findings of changing footwear insole stiffness on ankle joint moment were mixed so far.

Foot and lower leg pronation is a universal movement occurring during locomotion (Nigg et al. 2019). Pronation is still cited as a risk factor in the apparition of some running-related overuse injuries although high evidence is lacking (Willwacher et al. 2022). Studying the influence of external loadings on internal loadings could help to understand the aetiology of tissue injury (Paquette and Miller, 2018). Such an approach could challenge the relevance of the pronation-related kinematic variables classically used in biomechanical studies, especially when an intervention like motion control footwear is assessed.
足部和小腿内旋是运动过程中普遍发生的动作(Nigg et al. 2019)。尽管缺乏充分的证据，但内翻仍被认为是一些与跑步相关的过度使用损伤出现的风险因素(Willwacher et al. 2022)。研究外负荷对内负荷的影响有助于了解组织损伤的病因(Paquette and Miller, 2018)。这种方法可能会挑战生物力学研究中经典使用的旋前相关运动学变量的相关性，特别是在评估运动控制鞋等干预措施时。

Such an approach could challenge the relevance of the pronation-related kinematic variables classically used in biomechanical studies, especially when an intervention like motion control footwear is assessed.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S12 - S13"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46993036","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}
