This study sought to compare the kinetics and kinematics data in a group of habitual shod runners when running in traditional running shoes and newly designed minimalist shoes with lug platform. This novel footwear design claims to simulate barefoot running and reduce energy loss during impact. We compared footstrike angle (FSA), vertical average (VALR) and instantaneous (VILR) loading rates, energy loss and initial vertical stiffness between two shoe conditions. Runners demonstrated a decreased FSA while running in minimalist shoes with lug platform than traditional shoes (P = 0.003; Cohen’s d = 0.918). However, we did not observe a landing pattern transition. VALR and VILR between two footwear conditions showed no significant difference (P = 0.191–0.258; Cohen’s d = 0.304–0.460). Initial vertical stiffness (P = 0.032; Cohen’s d = 0.671) and energy loss (P = 0.044; Cohen’s d = 0.578) were greater when running in minimalist shoes with lug platform. The results show that minimalist shoes with lug platform reduce the FSA but may not lead to a landing pattern switch or lower vertical loading rates. Interestingly, the new shoe design leads to a greater energy loss than traditional running shoes, which could be explained by a higher initial vertical stiffness. 相似文献

Art and movement are motivating forces in, through, and beyond education. As populations age, there is an increasing need to support physical and social well-being. Yet, since the onset of the COVID-19 pandemic, there has been a reported exponential increase in feelings of loneliness across generations. Complex challenges require trans-disciplinary solutions, and this paper represents a joint effort within and across disciplines, communities and cultures to find ways to ameliorate this silent epidemic. In this paper, we propose a cross-disciplinary conceptual framework where Aboriginal Artists and Knowledge Holders, Teacher Educators, and Physical and Occupational Therapists come together to explore theoretical and pedagogical insights that encompass intergenerational art–moving–well-being practices, reducing feelings of loneliness and improving social connections across generations. There are two main aims of this paper; first, to better understand current studies that report on integrating art–moving–well-being practices, and the effect this has on health and well-being of intergenerational participants (under 10-year-olds, 20+ year olds and 50+ year olds). Second, based on community needs, the long-term aim is to propose a flexible art–moving–well-being conceptual model that is scalable, sustainable and based on social and relational support systems. We propose a model that is flexible and adaptable within and across our local community and beyond. We argue that feelings of loneliness are unique to each individual, and there is a need to connect specific intergenerational programmes with art–moving–well-being practices that readily engage and integrate varied communities and cultures in sustainable ways and thus, contribute to thriving communities. 相似文献

This paper describes a vision-based system for blind spot detection （BSD） in intelligent vehicle applications. A camera is mounted in the lateral mirror of a car with the intention of visually detecting cars that are located in the so-called blind spot and cannot be perceived by the vehicle driver. The detection of cars in the blind spot is carried out using computer vision techniques, based on optical flow and a double-stage data clustering technique for robust vehicle detection. 相似文献

ABSTRACTLibraries face many challenges in making electronic resources accessible and discoverable. In particular, the exponentially incre-asing number of licensed and open access electronic resources and the dynamic nature of consortial collections (platform changes, title transference between packages, and package overlap) present challenges for cataloging and discovery. From March 21 to April 10, 2017, the authors performed a selected review of library literature and conducted a survey of library consortia worldwide to ascertain the cataloging models, strategies, and advanced technological tools used to ensure discovery of consortial collections. The findings from the literature review and survey are summarized in this article. 相似文献

In this article, we report the findings of an exploratory empirical study that investigated the relationship between English Language Proficiency (ELP) on performance on the Woodcock‐Johnson Tests of Cognitive Abilities‐Third Edition (WJ III) when administered in English to bilingual students of varying levels of ELP. Sixty‐one second‐grade students, identified as Limited English Proficient, were recruited from a suburban public school district and were given the WJ III in addition to their annual state standardized assessment of ELP. The findings of this study provide evidence to support a linear, inverse relationship between ELP and performance on tests that require higher levels of English language development and mainstream cultural knowledge. The implications of the findings of the present study suggest that practitioners must consider an examinee's level of developmental language proficiency and cultural knowledge acquisition as continuous variables when determining the impact of such factors on test performance and evaluation regarding whether scores obtained from tests administered in English are indeed valid for interpretation. 相似文献

Gait retraining using visual biofeedback has been reported to reduce impact loading in runners. However, most of the previous studies did not adequately examine the level of motor learning after training, as the modified gait pattern was not tested in a dual-task condition. Hence, this study sought to compare the landing peak positive acceleration (PPA) and vertical loading rates during distracted running before and after gait retraining. Sixteen recreational runners underwent a two-week visual biofeedback gait retraining program for impact loading reduction, with feedback on the PPA measured at heel. In the evaluation of PPA and vertical loading rates before and after the retraining, the participants performed a cognitive and verbal counting task while running. Repeated measures ANOVA indicated a significant interaction between feedback and training on PPA (F = 4.642; P = 0.048) but not vertical loading rates (F > 1.953; P > 0.067). Pairwise comparisons indicated a significantly lower PPA and vertical loading rates after gait retraining (P < 0.007; Cohen’s d > 0.68). Visual feedback after gait retraining reduced PPA and vertical loading rates during distracted running (P < 0.033; Cohen’s d > 0.36). Gait retraining is effective in lowering impact loading even when the runners are distracted. In dual-task situation, visual biofeedback provided beneficial influence on kinetics control after gait retraining. 相似文献

This study examined trunk muscle activation, balance and proprioception while squatting with a water-filled training tube (WT) and a traditional barbell (BB), with either closed (CE) or open eyes (OE). Eighteen male elite Gaelic footballers performed an isometric squat under the following conditions: BB-OE, BB-CE, WT-OE and WT-CE. The activity of rectus abdominis (RA), external oblique (EO) and multifidus (MF) was measured using electromyography, along with sway of the centre of pressure (CoP) using a force platform. Only the EO and the MF muscles exhibited an increased activity with WT (p < 0.01). In the medio-lateral direction both the velocity and range of the CoP increased significantly with WT (p < 0.01). Interestingly, the range of the CoP for the WT-CE condition was significantly lower than WT-OE (p < 0.05, d = 0.44), whilst the velocity of the CoP was marginally reduced (d = 0.29). WT elicited a greater level core muscle activation and created a greater challenge to postural stability when compared to a BB. It appears that WT does not benefit from vision but emphasises the somatosensory control of balance. The use of WT may be beneficial in those sports requiring development of somatosensory/proprioceptive contribution to balance control. 相似文献

Advances in three‐dimensional (3D) printing allow for digital files to be turned into a “printed” physical product. For example, complex anatomical models derived from clinical or pre‐clinical X‐ray computed tomography (CT) data of patients or research specimens can be constructed using various printable materials. Although 3D printing has the potential to advance learning, many academic programs have been slow to adopt its use in the classroom despite increased availability of the equipment and digital databases already established for educational use. Herein, a protocol is reported for the production of enlarged bone core and accurate representation of human sinus passages in a 3D printed format using entirely consumer‐grade printers and a combination of free‐software platforms. The comparative resolutions of three surface rendering programs were also determined using the sinuses, a human body, and a human wrist data files to compare the abilities of different software available for surface map generation of biomedical data. Data shows that 3D Slicer provided highest compatibility and surface resolution for anatomical 3D printing. Generated surface maps were then 3D printed via fused deposition modeling (FDM printing). In conclusion, a methodological approach that explains the production of anatomical models using entirely consumer‐grade, fused deposition modeling machines, and a combination of free software platforms is presented in this report. The methods outlined will facilitate the incorporation of 3D printed anatomical models in the classroom. Anat Sci Educ 10: 383–391. © 2017 American Association of Anatomists. 相似文献

The present article describes an exploratory study regarding the preferred cognitive assessment practices of current school psychologists. Three hundred and twenty‐three school psychologists participated in the survey. The results suggest that the majority of school psychologists endorsed that they base their assessment practices on an underlying theoretical framework, specifically Cattell‐Horn‐Carroll (CHC) theory. Despite this finding, the majority of those sampled continue to engage in traditional assessment practices that are not consistent with CHC theory. Furthermore, the majority of those sampled reported that they assess culturally and linguistically diverse students and modify their practices when doing so. Unfortunately, the modifications endorsed by those surveyed might be discriminatory. The implications of these findings are discussed herein. 相似文献
