(1) Background: The aim of this study was to conduct a systematic literature review and meta-analysis on the effects of virtual reality (VR) and traditional (TR) physical activity programs, analyzing their impact on the physical, health, and cognitive aspects of participants. The study sought to identify the advantages and limitations of both methods, taking into account previous research and potential areas for future studies. (2) Methods: The study protocol for this systematic review was registered at the International Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY202530015). The review followed PRISMA guidelines, and studies were selected based on their relevance to the research objectives using the PICOS model criteria. The authors applied a meta-analysis in addition to a systematic review to further ensure the accuracy of the results. Primary outcomes included physical and cognitive performance, while secondary outcomes encompassed participant perceptions and psychological effects. (3) Results: The findings indicate that VR training significantly enhances flexibility, motivation, and cognitive abilities, particularly in populations with limited access to traditional exercise methods. The most pronounced effects were observed in programs lasting 8 to 12 weeks with a moderate to high intensity. In contrast, TR showed superiority in developing strength, endurance, and cardiorespiratory functions. (4) Conclusions: VR offers significant benefits as an adjunct or alternative to TR, especially for individuals with limited resources or physical accessibility. However, variations in methodological approaches, short program durations, and sample heterogeneity highlight the need for further longitudinal research. Standardizing VR training duration and intensity is essential to ensure consistent and reliable outcomes.

Background: Clubfoot is a congenital deformity that can affect one or both of a newborn’s lower extremities. The main objective of the study is to evaluate and compare the outcomes of the Ponseti method for the management of different types of clubfoot. Methods: A retrospective analysis of 151 children with 253 clubfeet (idiopathic untreated, idiopathic recurrent, and syndromic) with at least one year of follow-up was conducted in four months after ethical approval. Data were collected with a structured proforma after the consent of the parents. An independent sample t-test was applied to show the comparison between the groups, and a p-value of 0.05 was considered significant. Results: Out of 151 patients, 76% were male and 24% were female. Out of a total of 235 feet, 96 (63%) were idiopathic untreated, 40 (26.5%) were idiopathic recurrent, and 15 (9.5%) were syndromic clubfoot. The average number of casts was higher in syndromic clubfoot (9 casts per foot). There was no significant difference in the baseline Pirani score of the three groups (p-value > 0.05); but after one year of follow-up, there was a significant difference in the Pirani score of idiopathic and syndromic clubfoot (p-value ≤ 0.05) and between recurrent clubfoot and syndromic clubfoot (p-value = 0.01). Conclusions: The aetiology of syndromic clubfoot affects the outcomes of the Ponseti method and leads to relapse. In idiopathic (untreated and recurrent) clubfoot, the Ponseti method does not produce a significant difference in outcome. Poor brace compliance and a lack of tenotomy lead to orthotic (ankle foot orthosis AFO and foot orthosis FO) use in the day time and the recurrence of clubfoot deformity in these three types of clubfoot.

(1) Background: The relationship between physical activity (PA) and mental health remains a topic of significant interest, particularly in populations recovering from COVID-19. This study aimed to examine the differences in PA levels and mental health parameters (anxiety, depression, and stress) across sex and age groups following COVID-19 recovery; (2) Methods: The sample of participants (n = 288) was selected using a random sampling method and consisted of participants of different ages and both sexes. Participants’ self-reported PA was assessed using the International Physical Activity Questionnaire (IPAQ), while the Depression, Anxiety, and Stress Scale (DASS) was used to measure negative emotional states. The influence of COVID-19 recovery on PA and mental health (depression, anxiety, stress) was analyzed using MANOVA and follow-up univariate tests by age and sex. Statistical significance was set at p < 0.05, with SPSS (v23.0) used for data analysis; (3) Results: A statistically significant difference was observed between the initial and final measurements in PA levels (Wilk’s Lambda = 0.95; p = 0.000) and mental health (Wilk’s Lambda = 0.96; p = 0.000) with older individuals—particularly women—demonstrating improved PA levels and better mental health outcomes. In contrast, younger women exhibited a decline in both domains, with increased anxiety, depression, and stress symptoms. While younger men showed increased PA, their mental health parameters were slightly elevated, though still within normal ranges; (4) Conclusions: Our findings suggest that older individuals were better adapted to post-COVID challenges due to maturity and life experience, while younger populations may require additional support. The study underscored the complexity of the PA–mental health relationship and highlighted the need for further research, particularly among younger individuals recovering from COVID-19.

(1) Background: The aim of this study is to investigate whether the application of adaptive sports programs, initially designed for children with disabilities, can have a positive effect on physical fitness and body composition in healthy primary school children; (2) Methods: The sample comprised 80 participants, equally divided by gender (50% male, 50% female), with a mean age of 11.5 (SD = 0.03). They were divided into two groups, an experimental and a control group, with an even gender distribution. The research lasted 12 weeks, with additional classes allocated for the initial and the final measurements. The Eurofit test battery assessed physical fitness; (3) Results: ANCOVA revealed significant group differences in body composition variables within the total sample and gender distribution (p < 0.001). Significant differences were observed in handgrip strength (HGR), flamingo balance test (FBL), shuttle run 10 × 5 m (SHR) (p < 0.001), and also hand tapping (HTP) (p = 0.01). Participants in the experimental group outperformed the control group, highlighting the effectiveness of the intervention program. Specifically, boys in the experimental group showed significant improvements in HGR and SHR (p < 0.001), while girls improved significantly in HGR, FBL, and SHR (p < 0.001); (4) Conclusions: The experimental program, which incorporates sports elements for disabled individuals, led to significant improvements in the physical fitness parameters of children.

Shockwave therapy is a noninvasive treatment technique used in multidisciplinary fields, such as sports medicine, physical therapy, and orthopedics. This method of treatment is recommended for medical conditions, such as muscle contractions, intramuscular hematoma, or Dupuytren’s contracture. The shockwaves are high-energy pressure waves characterized by nonlinearity, high frequency, and peak pressure followed by low-pressure amplitude which are transmitted through an applicator to the affected tissue. In the case of spinal muscles, the conventional applicator can only be used on one side of the spinal cord at a time. Taking this into consideration, the approach suggested in this paper involves the design of a dedicated dual-tip applicator. This process implied predesign, finite element analysis, statistical analysis of the data, and optimization. We analyzed the input factors, such as frequency, pressure, applicator tip distance, shape, flatness, and material along with their effects, namely induced stress, tissue contact pressure, total strain energy, and propagation velocity. The proposed final design of the applicator uses geometric features suggested by the optimization analysis and also mechanical design features.

(1) Background: Physical inactivity is a major public health concern in modern society. Group fitness programs are widely used to promote physical activity, combining choreographed movements with various dance steps and music. This study aimed to examine the effects of Zumba and MoFit group fitness programs on body composition parameters in women. (2) Methods: The study included 98 female participants (Mean age = 27.8 ± 2.9 years), divided into three groups: E1 (n = 33), which followed the experimental Zumba program; E2 (n = 31), which followed the experimental MoFit program; and a control group (n = 34), which continued with their usual daily activities for 10 weeks. Body composition was assessed using 14 variables measured with the InBody 270 analyser. Statistical analyses included paired t-tests, MANCOVA, and ANCOVA. (3) Results: The findings confirmed the positive effects of both group fitness programs on most body composition parameters in women (p < 0.001). However, Bonferroni post hoc test results indicated that the Zumba program led to significantly greater improvements in most body composition variables compared to the MoFit program. (4) Conclusions: Both Zumba and MoFit programs were effective in reducing body fat, increasing muscle mass, total body water, and mineral content, whereas the control group did not achieve positive changes.
