Comparative Analysis of Kinetic Responses and Injury Risk During Landing from 45 cm Height: A Study of Barefoot vs. Sports Shoes Conditions

Jumping and landing biomechanics are closely related to the risk of acute injury due to prolonged exposure to high-ground reaction forces in basketball-like sports, which can lead to lower-limb musculoskeletal injuries in the hip, knee, and ankle. Footwear greatly impacts jumping mechanics, but going barefoot provides a unique perspective on how the human body interacts with the ground. This study aims to find out the kinetic responses during drop landing from 45 cm height with and without sports shoe conditions. Twenty-five healthy young adults were volunteers for this study. Kinetic parameters were recorded and processed by using Quattro Jump force plat and Mars Quarter performance analysis software. Data were presented as mean ± SD values and statistical analysis was performed using statistical software package SPSS-26. The drop landing data of with and without shoe shows scattered parameters with maximum forces of 4706.12N and 5393.04N at 45 cm height, indicating a 66% and 75% risk of metatarsal injury. The stabilization force was 632.64N and 623.64N at 45 cm, reached at 0.58s and 0.66s respectively. Time from Max Force to MFBS Regression analysis indicated a low R-squared value and a random fit plot. In barefoot (without shoe) conditions, the initial contact force, and maximum force were 85.71% and 13.60% higher (250N and 5393.04N respectively) compared to landing with shoes (100N and 4706.12N). However, the stabilization force was higher (632.64N) when landing with shoes compared to landing barefoot (623.64N). As a result, the risk of musculoskeletal injuries and joint stress was higher when landing barefoot due to the higher initial contact force and maximum force. On the other hand, landing with shoes enhances balance and stability due to the higher stabilization force.

A Reliability Study of the Load Distribution Percentage While Walking Using Curalgia Feet Sx Smart Insoles.

Background Gait analysis has evolved through many years of research. Many methods are used to analyze the gait of a subject. Recent times have showna high demand for wearable sensor-based insoles integrated with smartphone-based devices used for gait analysis due to ease of use. This study utilized Curalgia Feet Sx Smart Insoles and its software toolset, Gait Analysis+, designed and manufactured in India making it an accessible and cost-effective option. The Curalgia Feet Sx Smart Insoles allow for a broad range of biofeedback-based rehabilitation and recovery training for several patients and have many applications, such as sports performance enhancement and neurological disorder rehab (e.g., brain stroke rehab). The system also significantly delays the onset of neurodegenerative illnesses by providing balance and proprioceptive training. The smart insole can help the athlete, the coach, and the sports medicine team get the on-field data in real-time, which will help them understand if any technical or biomechanical alterations are required. This may help in performance enhancement. This study aimed to determine the interrater reliability of the load distribution percentage parameter of the Curalgia Feet Sx Smart Insole for both feet while walking in a controlled setting. Methodology A total of 120 subjects were enrolled in the study. In total, 90 subjects were randomly selected using Research Randomizer which included male and female students and staff at Sardar Bhagwan Singh University. The subjects were asked to come to the research lab of the physiotherapy department wearing their sports shoes. Curalgia Feet Sx insoles were inserted into the shoe firmly to fit properly. Two assessors took two readings after the smart insole was connected to the smartphone-based application, GaitAnalysis+, via Bluetooth. The dynamic analysis option was selected, and each subject's analysis was done one after another with a desirable break in between. Each subject walked for three minutes at their normal speed after pressing "Start Analysis." At the three-minute mark, the subjects were asked to press "Stop Analysis" and the investigator downloaded the report on the smartphone. The data collected was compiled as the cumulative weight in kg (load distribution) borne and the % weight (load distribution %) borneby each foot for the duration of the walk. Statistical analysis was done using Karl Pearson's test and interclass correlation calculation. Results Assessor 1 and Assessor 2 collected readings for the left foot as "L" and the right foot as "R." Assessor 1 readings were L1-R1 for load distribution and L1% and R1% for load distribution %. Assessor 2 readings were L2-R2 for load distribution and L2% and R2% for load distribution %. The r value (correlation coefficient) was calculated using the load distribution. The mean value of L1 was 337.46 (SD=94.16). The mean L2 was 313.6 (SD=104.40). The R1 mean was 229.03 (SD=112.88), and the R2 mean was 233.011 (SD=79.84). The r was 0.7171 for the left foot and 0.7502 for the right foot, suggesting an excellent correlation. The ICC was calculated for load distribution %. The means of L1% was 55.94, L2% was 57.59, R1% was 44.06, and R2% was 42.41. The ICC was found to be 0.91 for both feet, suggesting high interrater reliability for the tested parameter. Conclusions The findings confirmed that the Curalgia Feet Sx Smart Insoles presented good interrater reliability for the load distribution % parameter.

Analisis Rasio Profitabilitas Dan Rasio Aktivitas Sebagai Dasar Penilaian Kinerja Keuangan PT. Sepatu Bata Tbk

PT Shoes Bata Tbk is a company engaged in the manufacture of leather shoes, canvas shoes, casual and sports shoes, injection/slop sandals and industrial footwear safety mats. Financial performance is a description of the financial condition of a company which is analyzed using financial analysis tools, usually the measure used is the ratio. Research conducted by the author to analyze the financial performance of PT Shoes Bata Tbk based on profitability ratios and activity ratios. The profitability ratio can be measured by Gross Profit Margin, Net Profit Margin, and Return on Investment. Where Gross Profit Margin and Net Profit Margin are ratios that measure the company's ability to earn profits on sales, Return on Investment is a ratio that measures the company's ability to use all assets owned to generate profits after tax. The activity ratio can be measured by Receivable Turnover, which is a ratio that measures the company's ability to quickly manage the level of accounts receivable turnover. Inventory Turnover is a ratio that shows how quickly inventory turns over in sales activities. And Total Asset Turnover is a ratio that measures a company's ability to create sales using all the assets it owns. The aim of this research is to find out and analyze the financial performance of PT SEPATU BATA Tbk during 2016-2021 based on the two ratios. This research uses a descriptive qualitative approach method. The data source used is secondary data in the form of profit/loss financial report data and balance sheet reports. The results of this research indicate that the financial performance of PT Shoes Bata Tbk for the 2016-2021 period based on GPM is considered very good because the company was able to reduce the cost of goods sold, resulting in high sales and high gross profit. NPM is considered not good because the net profit generated is less with quite high sales. ROI is considered very poor because the high total assets are not commensurate with the net profit generated. RT is considered very good because it increases every year. IT is considered very poor due to the decrease in cost of goods sold and increase in average inventory each year. TAT is considered quite good because the company is able to manage its assets well. Financial performance as measured by the profitability ratio and activity ratio can be said to be less efficient, because the components of the profitability ratio and activity ratio are still low and do not reach good company standards.

How an In-Store Self-Service Technology Impacts Customer Shopping Experience, Satisfaction and WOM Intentions

Retailers are increasingly using self-service technologies (SSTs) in-store. However, their impacts are not well known. The objective of this study is to establish whether the use of SST and its key characteristics (perceived ease of use (PEOU) and perceived usefulness (PU)) has a significant effect on the customer experience (i.e., cognitive, affective, sensory, behavioral and social dimensions). The effect of these dimensions on satisfaction and positive word-of-mouth (WOM) intent were also investigated. We conducted an in-store experiment in which half of the 102 participants chose sports shoes using an interactive wall while a salesperson exclusively assisted the other half. The results demonstrate that the cognitive/positive affective and sensory dimensions of the experience are positively influenced by use of SST while the social dimension is diminished. Further, when SST was used, the negative affect increased. For customers who used the SST, PEOU and PU contribute to enhance all dimensions of the experience, except for PEOU which lowers the social experience. Customer experience positively impact consumer’s satisfaction and WOM intent.

Country-of-Origin Effect in the Marketing of Sports Shoes among University Students

The aim of this study is to examine the Country-of-Origin (COO) effect in the marketing of sports shoes among university students. 156 university students were randomly distributed into three groups and exposed to a fictitious sports shoes’ advertisement. COO information was not provided in the Control Group (n = 53). The experimental groups were provided information on COO from either a country with high COO scores (n=50) or low COO scores (n=53). A one-way ANCOVA found that there was a significant difference in Perception of Quality of the sports shoes between groups, F(2,152) = 2.98, p <.10 with respondents exposed to the advertisement featuring a country with high COO scores reporting the highest level of perceived quality. However, there was no significant difference across the groups for purchase intention. This suggests that COO effect exists for perception of quality but does not translate to purchase intention. Keywords: perception of quality, purchase intention, advertising, sports, footwear

A Systematic Review of Effects on ACL Injury of Soccer Shoe Outsoles, Soccer Playing Field Surfaces, and Outsole–Surface Interface

Soccer is a sport with a high incidence of injuries. The most common injury occurs when the anterior cruciate ligament of the knee has undergone a sprain, strain, or partial or total rupture. Besides fitness factors (e.g., proprioception, balance and strength capabilities), a principal cause of ACL injuries is sport shoes and playing surfaces. Especially with the emergence of artificial surfaces (rubbers, turfs, concrete, asphalt, red turf), the ACL injuries dramatically increase. The cost of ACL injuries is high both in terms of career termination and in social and economic costs. Thus, it is necessary to understand the impact of sport shoes and playing surfaces on the ACL and how it can be mitigated. The present literature review followed the PRISMA methodology to identify the major biomechanical factors influencing the behavior of surfaces and shoes in relation to the ACL damage. Fifty-eight papers were identified. After reviewing the mechanism of injuries, we identified several distinct factors: type of outsole and mechanical arrangement of the outsoles; shear forces; characteristics of artificial turf surfaces; effect of weather on artificial surface aging and change in mechanical characteristics; outsole/ground interface; and the frictional, tractional and rotational forces in the pathogenesis of ACL injuries in soccer.

Fuzzy Evaluation Model for Products with Multifunctional Quality Characteristics: Case Study on Eco-Friendly Yarn

Numerous advanced industrial countries emphasize green environmental protection alongside athletic healthcare. Many world-renowned sports brands are actively developing highly functional, environmentally friendly, and aesthetically pleasing products. For example, in the production of sports shoes, the eco-friendly yarn process is one of the important processes. This process involves multiple crucial larger-the-better quality characteristics closely tied to the functionality of sports shoes. Facing green environmental regulations and external competitors, it is evidently an imperative issue for enterprises to consider how to improve the quality of newly developed products, increase product value, and lower rates of both rework and scrap to accomplish the goals of saving energy and minimizing waste. Aiming to solve this problem, this study proposed a fuzzy evaluation model for products with multifunctional quality characteristics to assist the sporting goods manufacturing industry in evaluating whether all functional quality characteristics of its products meet the required quality level. This study first utilized the larger-the-better Six Sigma quality index concerning environmental protection for evaluation and then proposed product evaluation indicators for the eco-friendly yarn. Since the parameters of these indicators have not yet been determined, sample data need to be used for estimation. Enterprises require rapid response, so that the sample size is relatively small. Sampling error will increase the risk of misjudgment. Therefore, taking suggestions from previous studies, this study constructed the fuzzy evaluation model based on confidence intervals of quality indicators for the eco-friendly yarn. This method incorporated previous experience with data, thereby enhancing assessment accuracy.

Assessment of rheumatoid arthritis patients' knowledge about foot problems related to their illness and foot care practice.

Foot problems are very common in rheumatoid arthritis (RA). Podiatric intervention through therapeutic education of RA patients on the different potential foot problems could improve patients' knowledge and management of their foot problems. This study aimed to evaluate the knowledge of RA patients on podiatric problems related to their illness and foot care practices. This was a cross-sectional study including patients diagnosed with RA and aged older than 18years. Sociodemographic data, disease characteristics, and therapeutic data were collected. RA foot problems knowledge and foot care practice were assessed using a questionnaire combining questions developed from the literature search and a pretested validated questionnaire. Overall, 103 patients were included of whom 94 were female. The mean age was 56years (±10years) and the mean disease duration was 15years (±10years). Over 77% of patients reported never having received foot-health-related education. With regard to their knowledge about RA foot involvement, patients were aware that RA can affect the feet similarly to the hands (83%), lead to deformation of the foot (86%), lead to walking difficulties and falling (68%), and produce skin lesions of the foot (31%). Regarding participant's knowledge of appropriate footwear, 65% agreed that it would be beneficial to wear quality standard sports shoes. However, less than one-third of patients know the podiatrist's skills. Our study showed an awareness of the repercussions of RA on feet but a lack of knowledge on proper foot care, thus identifying a need for foot health therapeutic education.

Assessment of Public Awareness and Practices Regarding Tinea Pedis Among the Saudi Arabian Population.

Tinea pedis, commonly known as athlete's foot, is a fungal infection affecting the skin of the feet, primarily between the toes. Despite being a common condition, there may be gaps in knowledge and practices regarding its transmission, risk factors, and treatment options among the general population. This study adopted a cross-sectional research design. The study involved 2371 adult population in Saudi Arabia. The questionnaire was distributed online through social media means. Data was analyzed using IBM SPSS Statistics for Windows, Version 27 (Released 2020; IBM Corp., Armonk, New York, United States). A significant portion (66.1%) of respondents reported not examining their feet regularly. The majority (80.7%) of the respondents reported regular use of nail scissors as the common practice. The results further revealed that the majority of respondents (71.7%) were not aware of tinea pedis. Similarly, a large proportion (77.3%) of respondents were unaware of the risk factors associated with tinea pedis. However, among those aware, the most recognized risk factor was diabetes mellitus (82.3%), followed by peripheral arterial disease (37.1%), and immunocompromised conditions like HIV (31.3%). There was a significant association (p = 0.001) between regular foot examination practices and awareness of tinea pedis. In conclusion, there is low awareness regarding tinea pedis among the Saudi Arabian population. Only a small proportion demonstrated good knowledge of the condition and its symptoms. However, there is a relatively higher awareness of specific risk factors such as diabetes mellitus and peripheral arterial disease. Hence, it is imperative to enhance education and awareness campaigns to address the gaps in understanding tinea pedis, its associated risk factors, and symptoms, particularly among individuals engaged in physical activities and those who regularly wear sports shoes.

Assessing the Influence of Unstable Footwear on Lower Limb Lymphedema

Introduction: Unstable shoes may benefit lower limb lymphedema patients by reducing foot volume and relieving symptoms. Objective: The objective of this study was to evaluate and compare the effectiveness of unstable shoes versus conventional sports shoes in managing lower limb lymphedema, focusing on changes in foot volume, circumference, and symptom relief. Methods: We conducted an 8-week clinical trial, recruiting patients with lower limb lymphedema. Participants were divided into 2 groups: one using unstable shoes and the other using conventional sports shoes. Measurements of foot volume and circumference were taken at the beginning and end of the trial. Additionally, participants were asked to report any changes in leg cramps and paraesthesia during the study period. Results: The results indicated a nonstatistically significant tendency toward a decrease in foot volume and circumference in the intervention group using unstable shoes. In contrast, the control group using conventional sports shoes showed a tendency toward an increase in foot volume and a statistically significant increase in foot circumference. Moreover, participants in the unstable shoes group reported a decrease in leg cramps and paraesthesia, indicating potential symptom relief. Conclusions: This study suggests that unstable shoes have the potential to offer benefits to individuals with lower limb lymphedema, particularly in terms of foot volume reduction and symptom relief. The use of unstable shoes may be suitable for activities such as walking and extended periods of standing. However, further research is necessary to explore their full potential and effectiveness in managing lymphedema symptoms comprehensively.

Identifying distinctions in the perception of fast food and sport shoes brands by children and adolescents based on the brand meaning model

The article makes an effort to evaluate the influence of a brand meaning on the perception of popular products by children and adolescents on the example of junk food and sport shoes. The study involved 703 pupils of secondary schools from 11 to 18 years old. The proposed approach is based on the use of the Saaty's method, which allows to assess the influence of different factors on the perception of brands by children and adolescents and to determine the distinctions in their perception of brands of various types of products. Based on the analysis, a hierarchical structure of brand perception by children was built. It includes the brand awareness, brand logo recognition, consumer impression of brand advertising. The weighting coefficients of the hierarchical model for fast food and sport shoe brands were estimated and the results were compared, distinctions and similarities were identified in the perception of brands of various types of goods by children and adolescents. For fast food brands, perception of brand quality plays a major role, whilst for sport shoe the brand attractiveness is the most important factor.

Supercritical foaming of novel poly(ether‐b‐amide) elastomer and compression property characterization

AbstractLightweight foam made of poly(ether‐b‐amide) (PEBA) elastomer has been widely used in sport shoes due to its superior rebounding and supporting properties. Novel PEBA with polyamide 1012 as hard segments and poly(tetramethylene oxide) (PTMO) as soft segments was foamed by supercritical CO2. The influence of foaming process parameters, that is saturation temperature, pressure on the morphology of cellular structure was systematically studied by scanning electron microscopy (SEM) and wide‐angle x‐ray diffraction (WAXD). By controlling the viscoelastic behavior of PEBA at certain temperatures and pressures, foams with low density and energy loss coefficient can be fabricated. The cell density of 4.5 × 109 cells/cm3and expansion ratio of 16.0 of the foams can be obtained respectively. Cyclic compression performance of foams was systematically studied. For the foams with the highest expansion ratio, the energy loss coefficient of 11.9% in the first cycle and 3.5% after equilibrium were observed, which were less than those of former reported PEBA foams. The relationship between the Young's modulus and expansion ratio is in line with the Gibson–Ashby relationship.

Human-Robot Joint Misalignment, Physical Interaction, and Gait Kinematic Assessment in Ankle-Foot Orthoses.

Lower limb exoskeletons and orthoses have been increasingly used to assist the user during gait rehabilitation through torque transmission and motor stability. However, the physical human-robot interface (HRi) has not been properly addressed. Current orthoses lead to spurious forces at the HRi that cause adverse effects and high abandonment rates. This study aims to assess and compare, in a holistic approach, human-robot joint misalignment and gait kinematics in three fixation designs of ankle-foot orthoses (AFOs). These are AFOs with a frontal shin guard (F-AFO), lateral shin guard (L-AFO), and the ankle modulus of the H2 exoskeleton (H2-AFO). An experimental protocol was implemented to assess misalignment, fixation displacement, pressure interactions, user-perceived comfort, and gait kinematics during walking with the three AFOs. The F-AFO showed reduced vertical misalignment (peak of 1.37 ± 0.90 cm, p-value < 0.05), interactions (median pressures of 0.39-3.12 kPa), and higher user-perceived comfort (p-value < 0.05) when compared to H2-AFO (peak misalignment of 2.95 ± 0.64 and pressures ranging from 3.19 to 19.78 kPa). F-AFO also improves the L-AFO in pressure (median pressures ranging from 8.64 to 10.83 kPa) and comfort (p-value < 0.05). All AFOs significantly modified hip joint angle regarding control gait (p-value < 0.01), while the H2-AFO also affected knee joint angle (p-value < 0.01) and gait spatiotemporal parameters (p-value < 0.05). Overall, findings indicate that an AFO with a frontal shin guard and a sports shoe is effective at reducing misalignment and pressure at the HRI, increasing comfort with slight changes in gait kinematics.
