Abstract

The use of custom-made foot orthoses has been associated with numerous benefits, such as decreased impact accelerations. However, it is not known whether this effect could be due to better customisation. The present study analysed the effects of the first generation of a microwavable prefabricated self-customised foot orthosis vs. a prefabricated standard one on impact accelerations throughout a prolonged run. Thirty runners performed two tests of 30-min running on a treadmill, each one with an orthosis condition. Impact acceleration variables of tibia and head were recorded every 5 min. Microwavable self-customised foot orthosis increased the following variables in the first instants compared to the prefabricated standard one: tibial peak (min1: 6.5 (1.8) vs. 6.0 (1.7) g, P =.009, min5: 6.6 (1.7) vs. 6.2 (1.7) g, P =.035), tibial magnitude (min1: 8.3 (2.6) vs. 7.7 (2.4) g, P =.030, min5: 8.5 (2.6) vs. 7.9 (2.5) g, P =.026) and shock attenuation (min1: 61.4 (16.8) vs. 56.3 (16.3)%, P =.014, min5: 62.0 (15.5) vs. 57.2 (15.3)%, P =.040), and tibial rate throughout the entire run (504.3 (229.7) vs. 422.7 (212.9) g/s, P =.006). However, it was more stable throughout 30-min running (P <.05). These results show that the shape customisation entailed by the thermoformable material does not provide impact acceleration improvements. [ABSTRACT FROM AUTHOR]

Abstract

ABSTRACTSmall skin temperature asymmetries are claimed to indicate injuries, but the influence of measurement conditions and technical aspects of image acquisition are concerns for determining temperature asymmetries. This research determines whether distance and camera specifications affect thermal asymmetries detection. We simulated thermal asymmetries filling two glasses with water at different temperatures measured at two distances (0.7 and 1.5 m) using four different infrared cameras (T1020, E60BX, C2 and FLIR ONE). Linear regression verified the similarity between each camera and the T1020 camera (gold standard). The intraclass correlation coefficient assessed the inter-camera reproducibility. Linear regression reported increasing adjustment using mean temperature, with lower values at 1.5 m between the T1020 and FLIR ONE (0.7 m, r = 0.58; 1.5 m, r = 0.34), C2 (0.7 m, r = 0.90; 1.5 m, r = 0.62) and E60BX (0.7 m, r = 0.96; 1.5 m, r = 0.68). Higher inter-camera reproducibility was observed at 0.7 m than 1.5 m. It is preferable to take thermal images with shorter distances and to prioritise cameras with superior hardware characteristics. The portability of FLIR ONE and C2 may be an advantage in studies investigating expected differences greater than 0.05ºC and larger regions of interest.

Abstract

[EN] The use of rubrics can be an especially useful tool to align the teaching, learning and evaluation processes of oral presentation. Its validity is essential to assess academic performance and may be influenced by student self-regulation. The objective of the study was to determine the perception of validity and utility of a rubric for students of the Physical Education and Sports Sciences degree, as well as to identify the relationship between this perception, their academic performance and their self-regulation. 123 students participated in the study. The teacher of the subject provided the rubric to evaluate oral presentations. After oral presentations, students answered two questionnaires: one about the perception of the validity of the rubric and the other about self-regulation. In addition, their academic performance was recorded. The students positively assessed the rubric’s validity as a method of preparing and evaluating the oral presentation. Self-regulation presented a clearer direct relationship with the perception of rubric’s validity than academic performance, however, this relationship was weak and needs to be verified in future studies., [ES] La utilización de rúbricas puede ser una herramienta especialmente útil para alinear los procesos de enseñanza, aprendizaje y evaluación de la exposición oral. Su validez es fundamental para valorar el rendimiento académico y puede estar influenciada por la autorregulación del alumnado. El objetivo del estudio ha consistido en determinar la validez y utilidad que el alumnado de la titulación de Ciencias de la Actividad Física y el Deporte conceden a una rúbrica desarrollada al efecto, así como identificar la relación entre esta percepción, su rendimiento académico y su autorregulación. En el estudio participaron un total de 123 estudiantes. El profesor de la asignatura facilitó la rúbrica para evaluar exposiciones orales. Una vez realizadas las exposiciones orales, el alumnado respondió a dos cuestionarios: uno de percepción de validez de la rúbrica y otro de autorregulación. Además, se tuvo constancia de su rendimiento académico. El alumnado valoró positivamente la validez y utilidad de la rúbrica como método de preparación y evaluación de la exposición oral. La autorregulación presentó una relación directa más clara con la percepción de validez de la rúbrica que el rendimiento académico, sin embargo, dicha relación resultó débil y necesita ser contrastada en futuros estudios.

Abstract

Amateur runners usually run carrying implements in their hands (keys, a mobile phone, or a bottle of water). However, there is a lack of literature about the effects of different handloads on impact accelerations. Thus, this study aimed to analyse the effects of carrying different objects in the hand on impact accelerations during running. Nineteen male recreational runners (age 24.3 ± 6.8 years, training volume of 25 ± 7.38 km/week) performed twenty minutes of running on a treadmill at 2.78 m/s with four different conditions: no extra weight, with keys, with a mobile phone, and with a bottle of water. Impact acceleration and spatio-temporal parameters were analysed through a wireless triaxial accelerometry system composed of three accelerometers: two placed in each tibia and one placed on the forehead. A higher tibia acceleration rate in the dominant leg was observed when participants ran holding both a mobile phone (p = 0.027; ES = 0.359) and a bottle of water (p = 0.027; ES = 0.359), compared to no extra weight. No changes were observed in peak acceleration, acceleration magnitude, and shock attenuation in any other conditions. Likewise, neither stride frequency nor step length was modified. Our results suggest that recreational runners should not worry about carrying objects in their hands, like a mobile phone or a bottle of water, in short races because their effect seems minimal.
