(1) Medical training is changing, especially for surgeons. Virtual reality simulation is an excellent way to train surgeons safely. Studies show that surgeons who train with simulation have demonstrated improved technical skills in fundamental surgical procedures. The purpose of this study is to determine the overall impact of virtual reality training on laparoscopic cholecystectomy performance and to explore whether specific training protocols or the addition of feedback confer any advantages for future surgeons. (2) MEDLINE (PubMed), Embase (Ovid SP), Web of Science, Google Scholar, and Scopus were searched for the literature related to virtual reality training, immersive simulation, laparoscopic surgical skills training, and medical education. Study quality was assessed using the Cochrane Risk of Bias Tool and NIH Quality Assessment Tool. (3) A total of 55 full-text articles were reviewed. Meta-analysis showed that virtual reality training is an effective method for learning cholecystectomy surgical skills. (4) Conclusions: Performance, measured by objective structured assessments and time to task completion, is improved with virtual reality training compared with no additional training. Positive effects of simulation training were evident in global rating scores and operative time. Continuous feedback on movement parameters during laparoscopic cholecystectomy skills training impacts skills acquisition and long-term retention. Full article

The reliability and validity of the Jumpster app was assessed via a comparison to the Vertec during a countermovement jump. Using both tools simultaneously, 36 participants completed 100 total jump trials. Validity was assessed using correlation and tolerance analyses. Reliability was assessed using 95% predictive intervals (PI₉₅) and tolerance limits (TL₉₅) between the measures, comparing the standard error of the measure (SEM) and coefficients of variation (CVs) for each tool and by examining the intraclass correlation coefficient (ICC 2,K; upper and lower 95% CI) comparing both tools. The Jumpster app was weakly related to the Vertec (r = 0.24; p < 0.01). The tolerance analysis showed a moderately strong proportional bias of the Jumpster app to the Vertec (r = 0.45; p < 0.01). While all data fell within the calculated PI₉₅ ± TL₉₅, the Jumpster app SEM (14.7 cm) and CV (40.30%) exceeded the Vertec SEM (3.57 cm) and CV (7.22%), and the ICC was 0.55 [0.79, −0.08]. These results paired with an overall app failure rate of 15.97% indicate that the Jumpster app is neither reliable nor valid for measuring the countermovement jump. Full article

Background: Motor competence (MC) plays a critical role in shaping children’s physical activity, health-related fitness, and weight status. However, few studies have explored these interrelationships during middle childhood. Objectives: The current study aimed to examine the relationships between MC and physical activity (PA), health-related fitness (HRF), and weight status (WS) in children during middle childhood (9–10 years). Simultaneously, the study aimed to find possible differences in PA, HRF, and WS between children with different levels of MC. Methods: In this cross-sectional study, the TGMD-2 (MC), UNIFITTEST 6–60 (HRF), ActiGraph GT3X (PA), and anthropometry (WS) were administered to 86 children (59 boys, age range of 9–10 years and mean age of 10.1 ± 0.6 years). Results: A significant strong association was observed between MC and HRF (p < 0.01, Cramer‘s V = 0.42). Significant moderate associations were observed between MC and WS (p < 0.05, Cramer’s V = 0.34) and between MC and PA (p < 0.05, Cramer‘s V = 0.25). Children with high MC proficiency demonstrated significantly higher levels of HRF (p < 0.01; large ES) and PA (p < 0.05; moderate ES) and a healthier WS (p < 0.01; moderate ES) than those with low MC proficiency. Similarly, children with moderate MC proficiency outperformed children with low MC in terms of HRF and WS. Conclusions: The strong associations between MC and key health indicators such as PA, HRF, and WS suggest that movement proficiency in middle childhood should be viewed as a cornerstone of health promotion. Although no causal claims can be made, the results emphasize the practical importance of integrating targeted motor skill development—especially FMSs—into school-based physical education and extracurricular programs. Supporting MC at this age may be a decisive step toward fostering long-term engagement in physical activity and improving children’s overall health trajectories. Full article

Strong competencies in actual motor competence (AMC) and perceived motor competence (PMC) support lifelong physical activity. However, assessing MC is time-consuming, requiring multiple AMC and PMC evaluations. Streamlining these assessments would improve efficiency at a national level. This study used machine learning (ML) classification to (1) identify AMC assessments that can be accurately predicted in an Irish context using other AMC and PMC assessments, and (2) examine prediction accuracy differences between genders. AMC was measured using the Test of Gross Motor Development (3rd Edition) and the Victorian Fundamental Motor Skills Manual, while PMC was assessed with the Pictorial Scale of Perceived Movement Skill Competence. Five ML classification models were trained and tested on an Irish MC dataset (n = 2098, mean age 9.2 ± 2.04) to predict distinct AMC assessment outcomes. The highest prediction accuracies (>85%) were found for the Catch (female and gender-combined subsets) and Bounce (male subset) AMC assessments. These assessments could potentially be removed from the current Irish testing battery for their respective gender groups. Our findings highlight the effectiveness of ML classification in optimising Irish MC assessment procedures, reducing redundancy, and enhancing efficiency. Full article

Background: Childhood obesity is a global health concern. Early development of fundamental movement skills (FMS) and adherence to the Mediterranean diet (MD) are key modifiable factors for prevention. This study assessed the effectiveness of a multidisciplinary, school-based intervention for childhood obesity prevention. Methods: Children aged 3–5 years from a preschool in Messina, Italy, participated in a 9-month intervention integrating nutritional education and physical activity. FMS were evaluated using the MOBAK test. Anthropometric measurements and MD adherence (through the Kid-Med questionnaire) were collected. Caregivers completed an online survey reporting lifestyle changes. Results: Significant improvements were observed in FMS: object control (score 1) increased from 2.67 ± 1.78 to 4.28 ± 1.82, locomotor skills (score 2) from 4.69 ± 1.96 to 5.83, 5.83 ± 1.70, and total MOBAK score (score 3) from 7.35 ± 3.09 to 10.11± 2.94. (p < 0.001 for all). Kid-Med scores significantly improved from (3.79 ± 2.31 vs. 5.03 ± 2.69) (p = 0.0027), indicating enhanced MD adherence. Post-intervention, adherence was classified as poor (27.4%), moderate (53.2%), and optimal (19.4%). Although only a minority of parents reported lifestyle changes, over 50% noted increased fruit and vegetable intake in their children. Males showed higher FMS scores and waist circumference compared to females. Conclusions: A school-based multidisciplinary intervention significantly improved motor competence and dietary habits in preschool children. These findings underscore the importance of early, integrated strategies involving families and educators to support healthy development and prevent childhood obesity. Full article

This study examined the temporal relationship between fundamental movement skills (FMSs) and sport-specific skills (SSSs) in children aged 7 to 10. Based on the premise that FMSs are the basis for sport skills, we implemented a 10-week intervention program targeting two FMSs (running and stationary dribbling) and one SSS (speed dribbling), followed by immediate and long-term assessments. Using a path-modeling approach, we tested two models: one examining whether FMSs were associated with sport skill performance at the same time point and another exploring whether this influence emerged over time. Results revealed significant FMS and SSS improvements immediately after the intervention program. However, significant associations between the FMSs and SSS emerged only at later time points (8 to 20 months post-intervention), suggesting the delayed influence of the FMSs on the SSS. These findings support that while FMSs are essential for developing more complex skills, their effect may not be immediately observable, emphasizing the importance of long-term follow-up. The results also align with theoretical models contending that proficiency in FMS and sustained practice opportunities are key to integrating fundamental and sport-specific motor skills and may represent an important foundation for public health initiatives advocating early FMS interventions as a strategy to promote lifelong physical activity and sustained engagement in sports.

Running enjoys worldwide popularity across age groups and sexes. Because of this, it serves as an excellent benchmark to compare male and female performance across the lifespan with respect to developmental progression, peak athletic performance, and age-related regression. The purpose of this review is to examine and discuss how sex and aging affect running performance in sprints, middle-distance running, and long-distance running. Based on the scientific literature and running world records from age 5–99, male running performance exceeds that of females across the lifespan, with the greatest divide beginning at puberty, which remains through old age. However, there appear to be few differences in the rate of progression in youth and the age of peak performance, but it is unclear whether the rate of decline, beginning in middle age, differs by sex and sport for record performances. Future analyses should examine changes in all running performances across the lifespan. Full article

Background/Objectives: Global levels of physical activity are in decline, accompanied by low levels of competence in fundamental movement skills (FMSs) required to meaningfully participate in lifelong physical activity. This study aimed to explore the effects of an 8-week pilot program on the development of FMSs for children in a lower socioeconomic area through a game-based physical activity approach. Methods: Children (N = 30) were recruited from a lower socioeconomic area to participate in a community-offered PA program. This 8-week pilot program focused on game-based intervention, with weekly 1.5 h sessions to promote active play and development of FMSs. Each session was structured to ensure at least one FMS based on the Test of Gross Motor Development—Third Edition (TGMD-3) was emphasized to promote practice in these skills. The TGMD-3 was employed as a pre- and post-test measure of motor competence. Results: Children who completed both the pre- and post-test assessments (N = 11) demonstrated improvements in both locomotor (p = 0.166) and ball skill (p = 0.184) scores, though these were not significant. Additional analyses at baseline with all participants (N = 22; 8 not present at baseline testing) were insignificant, but descriptive statistics demonstrated that boys scored higher in ball skill scores, while girls scored higher in locomotor skill scores. Older children at baseline were found to score significantly higher than younger children in ball skill scores. Conclusion: The results highlighted that the game-based intervention did demonstrate some improvements for FMSs, highlighting a need for further development of the program and the participation of more children for more strongly powered analysis and to account for program withdrawal or dropout.

Background: Fundamental movement skills (FMS)—including muscular strength, endurance, and mobility—are linked to better health-related quality of life and higher physical activity in children. Rural children often score lower on FMS tests than urban peers due to resource limitations rather than ability. Thus, increasing access to FMS activities in under-resourced rural areas is essential. The primary objective was to test the feasibility of Hoosier Strength in a rural middle school sample, and the secondary objective was to observe the preliminary changes in FMS-related outcomes pre- to post-intervention and at follow-up. The exploratory objective was to explore how participants responded to different coaches on the Hoosier Strength coaching team (i.e., gender, coaching style during activities). Methods: This study used a Hybrid Type 3 design to evaluate feasibility and FMS outcomes, integrating qualitative and quantitative data. The four-week intervention included a test group (n = 24; 14 females, 10 males; mean age: females 12.4 ± 0.5 years, males 12.7 ± 0.4 years) and a control group (n = 12; 8 females, 4 males; mean age: females 12.9 ± 0.3 years, males 12.7 ± 0.3 years). Data analysis included descriptive statistics for feasibility indicators (Acceptability of Intervention Measures [AIM], Intervention Appropriateness Measure [IAM], and Feasibility of Intervention Measure [FIM]), linear regression for mobility and muscular endurance changes, t-tests for psychological need satisfaction and frustration, and regression analysis for squat knowledge and post-intervention confidence. Results: (1) There was high feasibility across the 4-week Hoosier Strength intervention and at follow-up; (2) there were no statistically significant changes in squat performance; (3) participants’ confidence in their ability to squat at the end of the intervention was significantly predicted by their squat knowledge at baseline; and (4) participants prioritized leadership and team management over tactical analysis, highlighting a preference for coaches who foster teamwork. Conclusions: The findings offer a transparent approach for evaluating the feasibility and preliminary outcomes of the Hoosier Strength intervention in an under-resourced rural middle school, thereby encouraging further investigation into strength training interventions in rural schools.

Background: Active play has been proposed to complement school-based physical activity (PA) and promote increased movement-related activities relevant for the development of motor competence. Guided active play (GAP) paired with cooperative games provides sufficient moderate-to-vigorous physical activity (MVPA) to improve motor competence for younger children. Whether guided active play exhibits physical activity outputs that are related to motor competence is uncertain. This study assessed the strength of relationships between play-based physical activity and movement skills by comparing linear regression and chi-square analyses. Methods: Forty-two children (Mage = 8.8 ± 0.8 years) participated in a community center program. PA was measured via accelerometry for GAP, alongside assessments of anthropometrics, fitness (leg power, strength, VO₂max), and FMS (Test of Gross Motor Development-2). Multiple linear regression analysis examined reciprocal relationships. Chi-square and cross-tabulations analyzed categorical variables based on lab percentiles (low < 33%, high > 66%) for PA energy expenditure (PAEE), intensity (MVPA), FMS, and fitness. Results: GAP MVPA and object control skills (OC) showed positive reciprocal pathways (β = 0.308, β = 0.394; p ≤ 0.05). VO₂max predicted MVPA (β = 0.408; p < 0.01), with leg power related to PAEE (β = 0.456; p ≤ 0.01). Chi-square analysis revealed significant associations between high OC skills and high PAEE (X² = 15.12, p ≤ 0.05), and high individual average scores of OC with high MVPA (X² = 11.90, p < 0.05. The high performance of AP and LP was associated with MVPA and PAEE, respectively. Conclusions: Findings support a positive feedback loop between MVPA and OC skills for GAP. GAP is an effective strategy for program interventions for children 8 to 10-year old. Full article

This paper proposes a theoretical model of meaning-making grounded in proprioceptive awareness and embodied imagination, arguing that human cognition is inherently multimodal, anticipatory, and sensorimotor. Drawing on Peircean semiotics, Lotman’s model of cultural cognition, and current research in neuroscience, we show that readiness to act—a proprioceptively grounded anticipation of movement—plays a fundamental role in the emergence of meaning, from perception to symbolic abstraction. Contrary to traditional approaches that reduce language to a purely symbolic or visual system, we argue that meaning arises through the integration of sensory, motor, and affective processes, structured by axial proprioceptive coordinates (vertical, horizontal, sagittal). Using Peirce’s triadic model of interpretants, we identify proprioception as the modulatory interface between sensory stimuli, emotional response, and logical reasoning. A study on skilled pianists supports this view, showing that mental rehearsal without physical execution improves performance via motor anticipation. We define this process as proprioceptive resonance, a dynamic synchronization of embodied states that enables communication, language acquisition, and social intelligence. This framework allows for a critique of linguistic abstraction and contributes to ongoing debates in semiotics, enactive cognition, and the origin of syntax, challenging the assumption that symbolic thought precedes embodied experience.

Background/Objectives: Trajectories of fundamental movement skill (FMS) development start diverging in females and males in early childhood, with determinants of this divergence spanning from individual to social and environmental factors. The present cross-sectional study focuses on the role of free outdoor play and aims to investigate whether sex differences in FMS typically observed in early childhood are associated with participation in free outdoor play. Methods: One hundred and forty-two children aged 4.3 ± 0.8 yrs were evaluated for locomotor and object control skills (TGMD-3), weight status (BMI), and free outdoor play (parent-reported). Motor skill competence scores were submitted to moderated regression analyses to evaluate the individual and joint effects of sex, outdoor play, age, and BMI; interrelations among these variables were also estimated with network analysis. Results: Results of the moderated regression showed, beyond the expected prediction of motor skill competence (overall and object control skills) by sex and age, also a significant sex x outdoor play interaction, with higher motor skills being predicted by more frequent outdoor play in males only. The network analysis confirmed a positive association between outdoor play and motor skill competence in males but not in females. Conclusions: Males might capitalize on free outdoor play opportunities as early as preschool age to engage in activities that promote their motor and especially object control skill development. Longitudinal studies are needed to test causality and derive practical indications for enabling both males and females to fully exploit the opportunities provided by free outdoor play to exercise both locomotor and object control skills.

Background: The open-stance forehand is a fundamental technique in tennis, playing a crucial role in competitive performance. Its execution depends heavily on lower limb coordination and neuromuscular control. Athletes of different skill levels often display distinct muscle activation strategies. This study employs non-negative matrix factorization (NMF) to analyze lower limb muscle synergy patterns during the forehand open stance across skill levels and explores their potential influence on stroke performance. Methods: A total of 30 tennis players, including 15 elite and 15 amateur athletes, participated in this study. Surface electromyography (sEMG) was used to record the activity of major lower limb muscles during the forehand open stance. Muscle synergy patterns were extracted using NMF, and K-means clustering was applied to classify synergy patterns. Independent sample t-tests were conducted to examine differences between muscle synergies. Results: Significant differences (p < 0.05) were observed in the spatial characteristics of each synergy component across different movement phases. However, temporal characteristics showed a significant difference only in Syn2 during the mid-phase of the backswing (BS) (56.2–60.4%) (p = 0.033). Conclusions: Elite athletes exhibited more optimized and stable muscle activation patterns, enabling more efficient coordination of major muscle groups. Based on sEMG decomposition and muscle synergy analysis, these activation patterns may contribute to improved stroke efficiency and energy transfer and potentially reduce the risk of sports-related injuries.

The aim of this study was to verify the effects of laboratory learning on children’s fundamental movement skills (FMS) through an intervention designed and implemented by specially trained generalist teachers. A total of 114 children attending 1st and 2nd grade of primary school (6.7 ± 0.8 yo) and 28 children attending preschool (4.1 ± 0.9 yo) in Naples (Italy) participated in the study. To assess FMS, the Movement ABC-2 (MABC-2) was administered. A two-way ANOVA for repeated measures was used to compare data. The laboratory was effective in improving coordination in primary school children, with a significant reduction in medium/severe movement difficulties from 23.7% to 12.4%. The results showed significant changes in the execution time of several MABC-2 tests, indicating an improvement in FMS, particularly hand-eye coordination and dynamic balance. However, the intervention was less effective in preschool children, with a limited improvement of 2.9%, highlighting that the intervention only had an impact on some specific skills. Targeted interventions can be effective in improving FMS, providing a basis for educational programs that respond to movement needs of students. Full article

Reaching is a fundamental motor skill essential for daily living, with over 50% of daily activities involving reaching movements. Understanding the development of postural adjustments made during reaching in early childhood is crucial for motor development. This study investigated the developmental characteristics of postural adjustments made by children aged 3–6 years during reaching tasks. A total of 135 typically developing children from Chinese kindergartens participated in this study. Kinematic and electromyographic (EMG) data were collected using an infrared motion capture system and surface electromyography, respectively. A two-way ANCOVA was performed to examine the effects of age and gender on kinematic and electromyographic parameters. Post hoc analyses revealed that completion time and shoulder angle showed a linear decreasing trend (p < 0.05). The variable wrist joint had an increasing trend in the high-touch task, while the elbow joint showed a nonlinear decreasing trend (p < 0.05). EMG results regarding Extensor Carpi Ulnaris (ECU) showed a decreasing trend at all phases (p < 0.05). The developmental patterns observed suggest that children progressively utilize more distal (wrist) and fewer proximal (elbow and shoulder) joints during reaching, indicating the maturation of motor patterns. However, the mechanisms of anticipation and compensation for children aged 3–6 are not yet fully understood. Full article
