With increased levels of obesity and the associated health concerns, exercise is being actively promoted across the population, resulting in an increased requirement for provision of sports facilities. One approach to this provision is through increased access to safe, high quality sports surfaces. Recent initiatives by governments as well as national and international sports governing bodies have led to increased funds being available for sports surfaces to be installed. In the UK, many of the new sports surfaces are synthetic. Advantages over natural sports surfaces, such as grass or cinder, include a reduced impact of weather conditions, lower levels of maintenance, and greater tolerance of multi-sport use. However, an increase in exercise and sport on artificial surfaces, as opposed to natural surfaces, has been suggested to have resulted in an increase in sport and exercise related injuries. For exercise to be a successful strategy for improving the health of the nation, it is important that quality, safe sports surfaces are provided. The proposed project takes a multidisciplinary approach to improving understanding of shoe-surface interaction, combining mechanical and biomechanical techniques. The project aims to improve the quality and safety of sports surfaces through an improved understanding of the factors associated with shoe-surface traction when performing on synthetic playing surfaces, with a specific focus on surfaces used in tennis and multi-sports surfaces utilised by a range of sports.The level of traction between the shoe and surface is the most frequently cited factor influencing injury occurrence and player performance. For example, a high percentage of injuries requiring medical treatment have been attributed to uncontrolled slipping as a result of low traction. In addition, ankle inversion injuries and anterior cruciate ligament (ACL) tears have been associated with a high level of traction between the shoe and the surface. An adequate amount of linear and rotational traction is required to allow stopping and turning movements, but extreme levels of traction may increase the loads on the body to intolerable levels. In addition to high levels of traction increasing injury risk, it is likely that unexpected levels of traction are dangerous. Within reason, if high traction is expected, the participant is likely to adapt their movement pattern to maintain loads at a tolerable level. However, if surfaces are not sufficiently uniform, then the participant may not adapt adequately and injury risk will be increased. To ensure player safety and thus encourage continued safe participation in exercise, increased understanding of the influence of artificial surfaces on human biomechanics is required. The planned project will address the problem of traction-related injuries in sport and exercise by considering the specific characteristics of shoes and surfaces that influence their translational and rotational traction behaviour under loads applied during sporting applications. To achieve this aim, a multidisciplinary approach will be used. Mechanical test methods will be developed to characterise playing surfaces, using biomechanical data to provide boundary conditions. Engineering approaches will be used to determine specific material characteristics influential on traction behaviour. Human testing will be used to validate the results of mechanical tests and to investigate relationships between human biomechanics and perception and the material properties of tennis surfaces and footwear. As well as improving understanding of the physical interaction between player-shoe combinations and sports surfaces, this work has the potential to lead to improving standard test procedures for surfaces, both integral to ensuring a high level of performance and comfort (to encourage participation), and reducing the likelihood of injury.

随着肥胖症和相关健康问题的增加，正在积极推动全民锻炼，从而增加了对提供体育设施的需求。实现这一目标的一种方法是增加获得安全、高质量运动场地的机会。政府以及国家和国际体育管理机构最近的举措已经导致可用于安装运动表面的资金增加。在英国，许多新的运动场地都是合成的。与天然运动表面（如草地或草皮）相比，其优点包括减少天气条件的影响，降低维护水平，以及更大的多运动使用容忍度。然而，与天然表面相反，在人造表面上锻炼和运动的增加已经被认为导致了运动和锻炼相关损伤的增加。为了使运动成为改善国民健康的成功策略，提供优质、安全的运动场地是很重要的。该项目采用多学科方法，结合机械和生物力学技术，提高对鞋表面相互作用的理解。该项目旨在提高运动场地的质量和安全性，通过更好地了解在合成运动场地上进行比赛时与鞋面牵引力相关的因素，特别关注网球场地和各种运动所使用的多项运动场地。鞋与场地之间的牵引力水平是影响受伤发生和运动员表现的最常见因素。例如，很高比例的需要医疗的损伤归因于由于低牵引力而导致的不受控制的滑动。此外，踝关节内翻损伤和前交叉韧带（ACL）撕裂与鞋和表面之间的高水平牵引有关。需要足够的线性和旋转牵引力来允许停止和转向运动，但是极端水平的牵引力可能会将身体上的负荷增加到无法忍受的水平。除了高水平的牵引力会增加受伤的风险外，意外的牵引力水平也可能是危险的。在合理范围内，如果预期高牵引力，参与者可能会调整其运动模式以将负荷维持在可容忍的水平。然而，如果表面不够均匀，那么参与者可能无法充分适应，受伤的风险将增加。为了确保运动员的安全，从而鼓励继续安全地参与运动，需要增加对人造表面对人体生物力学影响的理解。计划中的项目将解决运动和锻炼中与牵引力相关的损伤问题，方法是考虑运动鞋和表面的具体特性，这些特性会影响运动应用中施加的载荷下的平移和旋转牵引力行为。为实现这一目标，将采用多学科方法。将开发机械测试方法，使用生物力学数据提供边界条件，以模拟比赛场地。工程方法将用于确定影响牵引性能的具体材料特性。人体测试将用于验证机械测试的结果，并调查人体生物力学和感知与网球表面和鞋类材料特性之间的关系。除了提高对运动鞋组合和运动表面之间的物理相互作用的理解外，这项工作还可能导致改进表面的标准测试程序，这对于确保高水平的性能和舒适度（以鼓励参与）以及减少受伤的可能性都是不可或缺的。
