“…To compare the EMG signals to body movement, each movement cycle is divided into eight phases in the following discussion with folding hands in front of the chest as the cycle start point (Figure 4f). [46] BB and TB signals are generated by elbow bending and relaxation, [42] which closely match the insweep and outsweep motions in the Movie S3 (Supporting Information). The swimmer has BB signals from 6/8 T in the prior cycle to 1/8 T in the present cycle and TB signals appear at 1/8-4/8 T. No EMG signal is observed at 4/8-6/8 T as this is the gliding stage of each cycle and all muscles are in a relaxed state.…”

“…The function of the AT is to bend the ankle joint and turn the foot inward. [ 42 ] It contracts twice in a walking cycle. The first contraction occurs before the heel touches the ground, which is to ensure that the heel rather than the sole of the foot touches the ground first.…”

“…ST and BF signals reflect the bending of the calf and stretching of the thigh, respectively. [ 42 ] The GT's function is to bend the knee and assist in flexing the calf. [ 42 ] The combination of the above three signals can provide the information on leg motion.…”

“…These muscles were selected because of their location in the limbs and their crucial role in swimming activities. [42] They undergo more significant motion and experience more intense water flow impact compared to muscles in the trunk, such as the pectoralis major and latissimus dorsi. The EMG signals were normalized by dividing the maximum EMG signal of each muscle for better comparison, [3,45] (Figure 4e).…”

The quality of electrophysiological (EP) signals heavily relies on the electrode's contact with the skin. However, motion or exposure to water can easily destabilize this connection. In contrast to traditional methods of attaching electrodes to the skin surface, this study introduces a skin‐integration strategy inspired by the skin's intergrown structure. A highly conductive and room‐temperature curable composite composed of silver microflakes and polydimethylsiloxane (Ag/PDMS) is applied to the skin. Before curing, the PDMS oil partially diffuse into the stratum corneum (SC) layer of the skin. Upon curing, the composite solidifies into an electrode that seamlessly integrated with the skin, resembling a natural extension. This skin‐integration strategy offers several advantages. It minimizes motion artifacts resulting from relative electrode‐skin displacement, significantly reduces interface impedance (67% of commercial Ag/AgCl gel electrodes at 100 Hz) and withstands water flushes due to its hydrophobic nature. These advantages pave the way for promising advancements in EP signal recording, particularly during motion and underwater conditions.

Background and Study Aim. Biomechanics is a fundamental component of Kinesiology, offering critical insights into the mechanics of human movement. As the demand for comprehensive educational programs in Kinesiology grows, understanding the role and effectiveness of biomechanics within these programs becomes increasingly important. The aim of the study is to investigate and highlight the role and importance of biomechanics in the context of higher education, with an emphasis on the discipline of Kinesiology. Material and Methods. This study involved 71 students from the Department of Physical Education and Sport at Pitești University Center. It included 43 students specializing in Physical Education and Sport (PES) and 28 in Sports and Motor Performance (SMP). The research utilized the university's e-learning platform to monitor teaching and evaluation activities within the Kinesiology discipline. The evaluation of fundamental Kinesiology knowledge was assessed through various indicators. Google Forms-Questionnaire sought to gauge student opinions on the thematic content of Biomechanics as applied to Kinesiology and to evaluate the teaching staff. The nonparametric Kruskal-Wallis Test was employed to analyze differences in means across the groups. Results. The study revealed a diverse interest in sports across the Physical Education and Sport (PES) and Sports and Motor Performance (SMP) programs. Soccer, basketball, and handball were the most popular among students. Comparative analysis of academic performance showed no significant differences between the groups in various assessments (p>0.05). The overall student feedback on the "Fundamentals of Biomechanics of Physical Activities and Sports" course was predominantly positive. Over 50% of the students rated it as very good. Areas for improvement in teaching methods were also identified to enhance the academic experience. Conclusions. This study highlights the effective integration of biomechanics within the Kinesiology discipline at the higher education level. Findings suggest that well-structured educational programs can enhance students' understanding and application of biomechanics. This contributes positively to their academic and professional development in sports sciences. Continuous curriculum assessment and refinement are crucial for maintaining the relevance and effectiveness of such programs.

Sub-acromial Impingement Syndrome (SIS) is a prevalent shoulder pathology characterized by pain, muscle weakness, and altered joint position sense (JPS). This prospective study aimed to comprehensively assess the relationship between shoulder muscle strength, JPS, and pain in individuals with SIS. A total of 100 participants, including 50 with SIS and 50 healthy controls, underwent shoulder muscle strength testing and JPS evaluation in various directions (flexion, abduction, medial rotation, and lateral rotation). Pain intensity was quantified using a visual analog scale. Correlation analyses were conducted to explore the associations between muscle strength, JPS, and pain, with Cohen’s d values indicating the effect size. Individuals with SIS exhibited significantly lower shoulder muscle strength and greater JPS errors compared to the healthy controls (p < 0.001, Cohen’s d = 0.51 to 0.84). The results showed strong positive correlations between muscle strength and JPS in all assessed directions (p < 0.001, with r values ranging from 0.35 to 0.62). Mediation analysis revealed that pain partially mediated the relationship between muscle strength and JPS in all directions (p < 0.005). This study highlights the multifaceted nature of SIS, emphasizing the coexistence of muscle weakness, proprioceptive impairments, and pain. The findings underscore the importance of addressing these factors in the comprehensive rehabilitation of individuals with SIS to optimize functional outcomes and enhance their quality of life.
