The COVID-19 pandemic was an unprecedented situation that raised concerns about the physical and mental health of adolescents. Several surveys demonstrated that post-lockdown, women reported more complaints and lower perceived quality of life compared to men. The aim of this study was to analyze gender differences in self-reported physical and mental health immediately after the second lock-down restrictions (July 2020 to December 2020) were suspended and physical exercise classes resumed after a break of several months. This was achieved using a comparative cross-sectional survey of over-18-year-old students from the faculties of Sports Science and Physical Therapy at the University of Cadiz (UCA) in Spain. Quality of life was assessed using two types of questionnaires. The first covered quality of nutrition (PREDIMED), and the second assessed emotional impact (SF12). Physical activity level was estimated using the International Physical Activity Questionnaire (IPAQ). Of the 166 participants in this study, about two-thirds were men. Men had a better perception of their overall health quality than women. In addition, men had significantly fewer limitations in performing activities of daily living than their female counterparts. In contrast, female university students had better coping strategies, that is, they were better able to handle the problems of daily life and did so with more composure, attention, and concentration. These findings highlight the differences in post-release recovery between men and women and can be used to develop programs to promote better living standards and services to reduce gender disparities, which can ultimately improve quality of life.

Background/Objectives: Non-invasive radiofrequency (NIRF) therapy is increasingly used in physical rehabilitation. However, its efficacy across different lower limb pathologies remains unclear. This study aimed to evaluate the effects of NIRF on pain intensity and functional status in patients with musculoskeletal, neurological, and vascular conditions of the lower limb. Methods: A systematic review with meta-analysis of randomized controlled trials (RCTs) was conducted following PRISMA guidelines. The PubMed, Scopus, Web of Science, PEDro, and Cochrane Library databases were searched for RCTs comparing NIRF with sham, standard care, or other physical modalities. Methodological quality was assessed using the PEDro scale. Statistical analysis was performed using RevMan 5.4 to calculate Mean Differences (MD) and Standardized Mean Differences (SMD). Results: Nineteen RCTs comprising 911 participants were included in the qualitative review, of which 14 were included in the quantitative meta-analysis. The mean methodological quality was 7.78/10. The meta-analysis revealed favorable results for NIRF in reducing pain intensity compared to control groups (MD = −2.04; 95% CI = −3.14 to −0.93; p = 0.0003; I² = 96%). Functional outcomes also showed significant improvement in favor of the experimental group (SMD = −0.51; 95% CI: −0.85 to −0.16; p = 0.004; I² = 78%). Additionally, narrative synthesis indicated benefits for spasticity management (stroke) and limb volume reduction (lipedema/lymphedema). Conclusions: The results suggest a trend favoring NIRF for reducing pain and improving function in lower limb musculoskeletal conditions, particularly when used as an adjunct to active therapy. Evidence also suggests preliminary beneficial effects for neurological and vascular disorders. However, these findings must be interpreted with caution due to the high statistical heterogeneity observed, the broad diversity of the clinical populations included, and the wide variability in the treatment protocols applied. Further rigorous research with standardized protocols is highly recommended.

Introduction: First aid training within Physical Education provides an opportunity to develop essential competencies related to safety, prevention, and emergency response in school settings. The Organic Law 3/2020 (LOMLOE), which regulates the Spanish national education system, together with the Andalusian regional regulations, includes risk management as part of the subject’s learning standards and assessment criteria. This proposal presents a progressive didactic model for teaching first aid in Lower and Upper Secondary Education. Method: A didactic proposal was designed based on active methodologies and practical experiences, incorporating playful activities, simulations, workshops, and cooperative dynamics. The learning sequence was structured progressively, adjusting task complexity according to each educational level and integrating the required curricular learning standards. Evaluation followed a formative approach through rubrics, checklists, self-assessments, and learning portfolios. Results: The proposal supports the acquisition of key competencies such as the PAS protocol (Protect, Alert, Aid), basic cardiopulmonary resuscitation (CPR), the use of automated external defibrillators (AED), and intervention in common school emergencies. It also promotes transversal skills such as decision-making, effective communication, teamwork, and critical reflection on safety during motor practice. These elements contribute to meaningful learning and facilitate the transfer of knowledge to real-life situations. Conclusions: The implementation of this proposal helps foster a culture based on prevention and mutual care. Furthermore, it provides students with transferable skills applicable to everyday life and future professional contexts related to health, physical activity, and community intervention. This approach reinforces the role of Physical Education as a promoter of life skills.

The variables determining performance under different wind conditions in Olympic RS:X class sailors have not yet been fully clarified. The aim of this study was to examine the relationship between race performance (final ranking) and GPS-derived variables, including velocity made good (VMG), distance covered, and number of maneuvers, under different wind conditions in Olympic RS:X class sailors. Fifty-four Olympic RS:X class sailors (26 women and 28 men) who competed in a World Cup event were analyzed. Using GPS devices, the first-leg ranking, VMG, number of maneuvers, and distance covered in each segment (upwind, beam reach, and downwind) of every race were evaluated under three wind conditions (light wind: ≥8 to ≤12 knots; moderate wind: >12 to ≤15 knots; strong wind: >15 knots). A total of nine races were analyzed for both the men’s and women’s groups. For both groups and under all wind conditions, first-leg ranking was the variable most strongly associated with overall performance. VMG in upwind and downwind legs was among the most decisive variables in moderate wind conditions for both men and women. In strong wind conditions, VMG during the beam reach was a key variable influencing performance in both groups. In the women’s group, regardless of wind speed, VMG during the first upwind leg was the determining factor for achieving a better first-leg position. In the men’s group, particularly in medium wind conditions, a favorable first-leg position was mainly determined by VMG during the first upwind leg.
