Instrumentation in sports biomechanics
2007
La biomecánica deportiv emplea una serie de herramientas y técnicas de instrumentación paara el análisis de las diferentes disciplinas físico-deportivas, así como también para el desarrollo de nuevos materiales y equipamiento deportivo. Sin embargo, estas herramientas empleadas actualmente, poseen su cuerpo de conocimientos teóricos en los conocidos como "precursores de la biomecánica". Aristóteles, Da Vinci, Galileo, Descartes, Borelli, Newton, etc... El documento, presenta diferentes técnicas instrumentales desarrolladas para evaluar y aportar información relevante en la ejecución físico-deportiva, así como contribuir en la disminución de la epidemiología deportiva. Entre las principales …
Technological advancements in the analysis of human motion and posture management through digital devices
2021
Technological development of motion and posture analyses is rapidly progressing, especially in rehabilitation settings and sport biomechanics. Consequently, clear discrimination among different measurement systems is required to diversify their use as needed. This review aims to resume the currently used motion and posture analysis systems, clarify and suggest the appropriate approaches suitable for specific cases or contexts. The currently gold standard systems of motion analysis, widely used in clinical settings, present several limitations related to marker placement or long procedure time. Fully automated and markerless systems are overcoming these drawbacks for conducting biomechanical…
Markerless 2D kinematic analysis of underwater running : A deep learning approach
2018
Kinematic analysis is often performed with a camera system combined with reflective markers placed over bony landmarks. This method is restrictive (and often expensive), and limits the ability to perform analyses outside of the lab. In the present study, we used a markerless deep learning-based method to perform 2D kinematic analysis of deep water running, a task that poses several challenges to image processing methods. A single GoPro camera recorded sagittal plane lower limb motion. A deep neural network was trained using data from 17 individuals, and then used to predict the locations of markers that approximated joint centres. We found that 300–400 labelled images were sufficient to tra…
Effects of Minimalist Footwear and Foot Strike Patterns on Plantar Pressure during a Prolonged Running
2022
The use of minimalist shoes (MS) in running involves changes in running mechanics compared to conventional shoes (CS), but there is still little research analysing the effects of this footwear on plantar pressure, which could help to understand some risk injury factors. Moreover, there are no studies examining the effects of a prolonged running and foot strike patterns on baropodometric variables in MS. Therefore, the aim of this study was to analyse the changes produced using MS on plantar pressure during a prolonged running, as well as its interaction with the time and foot strike pattern. Twenty-one experienced minimalist runners (age 38 ± 10 years, MS running experience 2 ± 1 years) ran…
