Special Issue Information

Dear Colleagues,

Motion data collection during sports is crucial for athletes, coaches, and healthcare professionals to gather valuable information. Detailed data on athletes and their workout habits is vital for improving training programs and optimizing athletic performance. The recent surge in the use of motion monitoring devices has driven technological advancements in this field, offering innovative solutions. Motion monitoring systems integrate these devices with advanced back-end processing solutions to expedite the analysis and identification of exercise data, streamlining the motion monitoring process. This Special Issue aims to present a comprehensive examination of the latest developments in motion monitoring systems, encompassing technological innovations, practical applications, and future prospects. The Editorial Board welcomes researchers from various fields and disciplines to submit original research, reviews, case studies, and technical reports.

Continuous monitoring of the Stand-to-Sit (STS) transition serves as a critical indicator of lower-limb frailty in the elderly, for which millimeter-wave radar provides an ideal privacy-preserving, device-free sensing solution.

Continuous monitoring of the Stand-to-Sit (STS) transition serves as a critical indicator of lower-limb frailty in the elderly, for which millimeter-wave radar provides an ideal privacy-preserving, device-free sensing solution. However, robustly distinguishing between safe Controlled Sits (CSs) and dangerous Uncontrolled Descents (UDs) is severely hindered by the prohibitive cost of subjective expert scoring for fine-grained labels, alongside the pervasive “Clever Hans” effect where existing deep models overfit static environmental clutter rather than learning intrinsic human kinematics. To circumvent these bottlenecks, we formulate STS evaluation as a dynamic boundary detection problem and propose SCA-BiMamba, a linear-complexity bidirectional State-Space Model that utilizes actual fall events as extreme kinematic surrogates for UDs. This forces the network to learn a strict physical boundary between CS and physiological failure without subjective grading. Furthermore, we establish a stringent Real-to-Sim diagnostic audit as a core methodological contribution. By projecting models trained on noisy real-world data onto pure-kinematics simulations—incorporating stochastic temporal phase shifts, kinematic overlaps, and unified physiological tremors—we explicitly quantify feature disentanglement. This protocol serves as a formal ‘probing test’ to expose the ‘Clever Hans’ effect, ensuring the model relies on invariant human physics rather than transient environmental artifacts. Extensive experiments demonstrate that SCA-BiMamba achieves highly robust classification on real-world data (averaging 94.2% Macro F1 with 100.0% Uncontrolled Descent Recall), and achieves a highly robust 99.4% ± 1.1% Macro F1 in the simulated zero-shot transfer. We emphasize that this optimal performance reflects the successful abstraction of extreme kinematic boundaries, rather than a flawless resolution of all clinical complexities. Concurrently, it exhibits strict resistance to shortcut learning and sustains robust real-world scalability using merely 20% of the training data, thereby establishing a promising privacy-preserving boundary-based radar motion classification framework for distinguishing controlled sitting from extreme instability surrogates.

The triboelectric nanogenerator (TENG), which converts mechanical energy into electrical energy through the coupled effect of triboelectrification and electrostatic induction, has garnered significant interest among researchers due to its portability and self-powered characteristics. Despite its evident development potential, TENG continues to face challenges, including the necessity to enhance its triboelectric performance through the optimization of structures, materials, and manufacturing techniques to improve energy conversion efficiency. Additionally, its environmental stability and durability also need to be improved. TENGs designed inspired by non-human animals and plants offer feasible solutions to address these limitations. These bio-inspired TENGs optimize the structural design of TENGs and the materials of the triboelectric layers by imitating the structures, functions, and behaviors of organisms, thereby further improving the energy conversion efficiency, sensitivity, wear resistance, adaptability to special environments, biocompatibility, and wearing comfort of TENGs. This paper expounds on the progress of TENGs inspired by non-human animals and plants applied in environmental energy harvesting, human health and motion monitoring. It also discusses the current challenges, with a view to providing insights for the interdisciplinary integration and development of bionics and TENGs. Full article

This systematic review aimed to evaluate the tests used to assess neuromuscular performance in adult female basketball players and to provide evidence-based recommendations for practice and future research. Following PRISMA guidelines and registered in PROSPERO (CRD42025638889), four databases were systematically searched from inception to April 2026. A total of 62 studies were included in the qualitative synthesis and 39 in the quantitative analysis. The most frequently reported assessments examined anthropometry, muscular power, linear speed, change-of-direction (COD) performance, strength, anaerobic capacity, and aerobic capacity. However, substantial variability was observed in testing protocols, outcome variables, and reporting methods. Across studies, performance outcomes showed considerable overlap between competition levels, suggesting that competitive standard alone is not a reliable indicator of neuromuscular performance. Differences in anthropometric characteristics and physical performance were largely influenced by playing position and contextual factors. A key finding was the predominant reliance on outcome-based metrics (e.g., jump height, sprint time), with limited use of force–time variables that provide deeper insight into neuromuscular function. In addition, important methodological limitations were identified, including inconsistent testing procedures, lack of standardized reporting, and the absence of female-specific considerations such as menstrual cycle status. To address these limitations, this review proposes a practical testing framework that integrates reliable, sport-specific, and time-efficient assessment methods. Future research should prioritize the implementation of standardized protocols, the inclusion of force–time analysis, and the development of large-scale descriptive datasets specific to female basketball players. These advances are essential to improve performance monitoring, optimize training prescription, and enhance injury risk management in this population. Full article
