This project aims to develop, validate and implement a system based on nonlinear techniques to analyze movement variability under fatigue conditions. Inertial mass sensors (IMUs), including those in smartphones, will be used to democratize access to advanced nonlinear analysis tools in sports and educational contexts.
The impact of the project is broad. From a scientific perspective, it will allow us to advance our knowledge of fatigue and movement variability, as well as propose new evaluation metrics. At a technological level, the application of low-cost sensors and accessible software will contribute to the democratization of movement analysis, allowing coaches and educators to access advanced tools without the need for expensive equipment. At a sports level, the results will help optimize training and recovery strategies, reducing the risk of injury and improving performance. In addition, the use of nonlinear techniques in movement evaluation will transform the teaching of motor learning and biomechanics, facilitating their integration into the training of professionals in sports sciences.
This project seeks to have a significant impact on sports science, motor learning and technological innovation. From a technical point of view, a free web tool will be developed to assess coordinative fatigue in sport, using open source software, which will facilitate its adoption without relying on expensive equipment. This aspect represents an advance in knowledge about the effects of fatigue on movement variability through nonlinear analysis techniques, improving the understanding of neuromuscular adaptations and fatigue. This advance has the potential to democratize access to sports technologies, benefiting coaches and researchers.
The expected social and economic impact is significant, with the potential reduction of injuries and optimization of training loads, which could reduce rehabilitation costs and improve sports longevity. This would benefit clubs, health institutions and sports policies. The dissemination and transfer plan, as well as the data management plan, are sufficiently detailed and adequate.
The proposal integrates a clear gender perspective in its objectives, methodology, results and applications. The physiological and biomechanical differences between men and women in fatigue and movement variability are taken into account, and the equitable representation of both sexes in the proposed studies is envisaged. The digital tool that will be developed will be accessible to everyone, and the results will promote the health of female athletes, improving their access to advanced technologies without gender bias.
