“…Some studies suggest that a DCOF in the range of 0.2-0.4 is safe and not conducive to falls. Other researchers have reported that at DCOF levels below 0.3-0.35, people may modify their gait to avoid slipping [16]. Therefore, a safe coefficient of friction at the footwear-floor interface is assumed to be approximately 0.4 [34].…”

“…In summary, according to the literature guidelines and recommendations concerning the effects of different types of footwear on the risk of slipping and falling, older persons should wear footwear with short heels (less than 2.5 cm) to avoid the undesirable impact of high-heeled footwear on maintaining the optimum posture and balance [16,21,30,34,38,47].…”

Foot slippage is the most widespread unforeseen event causing falls on the same level, and a potentially contributing factor to falls from height and falls to a lower level. Statistical data on the number of slip-related accidents at work show the importance of the problem of slipping and indicate the need to continuously improve preventive measures designed to reduce injuries related to slipping, tripping, and falling (STF) on the same level. It is therefore necessary to continuously and insightfully analyze the causes of falls and undertake efforts to eliminate the occurrence of slip- and trip-induced workplace accidents. The occurrence of slips and trips is primarily related to the type and quality of floor surfaces, but it also depends on the biomechanical characteristics of the lower limbs in the transitional phases of walking gait, sole material and tread, human factors such as age, weight, and motor and vision function, the ability to adapt to the floor surface conditions, as well as on a number of factors linked to the workplace environment and work organization. This problem is going to escalate as a result of the higher retirement age, due to which many persons over the age of 60 will have to continue working, often in hazardous conditions.

“…These large variations in test devices make a direct comparison of results unreliable. Although studies have been conducted comparing the results of differing methodologies, both for sports situations and pedestrian slip [13][14][15][16][17][18][19] there is little evidence which device most clearly predicts the traction likely to be experienced by a human [20][21].…”

“…There is therefore a requirement for improved scientific understanding of shoesurface interactions in sport and the tribological mechanisms at play [13]. In clean, dry conditions, the traction developed between a viscoelastic tennis shoe outsole and a hard solid substrate (such as an acrylic hard court) will depend on the contribution of adhesion and hysteresis friction mechanisms [16,25,[30][31]. The traction provided by an artificial clay court will be dependent on the contact between the shoe and the clay particles and by inter-particle friction.…”

Abstract:The traction developed at the shoe-surface interface can have a significant influence on a player's injury risk and performance in tennis. The purpose of this study was to investigate shoe-surface traction on a dry acrylic hard court and two artificial clay court tennis surfaces in dry and wet conditions. A laboratory-based mechanical test rig was developed to measure the traction force developed at the shoe-surface interface. Linear regression analysis was used to examine the relationship between normal force and three measures of traction: initial stiffness, peak traction force and average dynamic traction force. The normal force did not significantly influence the initial stiffness for the shoe-surface system on the acrylic hard court but did on the artificial clay surfaces. The infill particle size and the addition of moisture influenced the traction developed on the artificial clay surfaces. Small, dry particles developed greater traction, and with a sufficiently high applied normal force will provide traction comparable to that on an acrylic hard court. However, increased particle size and/or the presence of moisture generally reduced traction. Strong and significant positive linear relationships were found between peak traction force and average dynamic traction force for all surface types and conditions. This study improves the understanding of the influence surface characteristics have on shoe-surface traction mechanisms. Once traction mechanisms are understood, surface properties and/or footwear can be effectively changed to maximise performance and/or minimise injury risk.
