Introduction: Submaximal strength testing appears to be valid to prescribe the intensity for strength training protocols that reduce the risk of injuries and testing time. Objective: This study aimed to assess the predictive ability of body mass parameters to estimate 4-6 repetitions maximum (4-6 RM) of Leg press 45°, Chest press, and Pull-down exercises. Methods: Eleven male bodybuilders (age 38.27 ± 10.48 years) participated in this study. Participants completed an incremental external load up to find the load allowing them to perform 4 to 6 maximal repetitions for each exercise in random order. The starting load was 50% of body mass for chest press and pull-down exercises and 100% for leg press. The load increment after each set was 20 kg for lower limb exercises and 10 kg for upper body exercises. Results: Results revealed that body mass had good to optimal relationships with 4-6 RM for all three exercises. Results showed that body mass had a good prediction ability for all three criterion measures. Conclusion: The prediction equations suggested in this study may allow coaches to estimate the 4-6 RM of leg press 45°, chest press, and pull-down performances. Evidence Level IV; Case series.

The complex approach represented by the physical training and especially by the explosive force, in the case of a handball team must be approached with professionalism, especially during the training period by customizing the training program for each athlete. During the study we found that this concept of muscle training in explosive force is not fully understood, the forms of response showed that it does not appear in training programs insofar as it can have a significant influence, implicitly neither coaches considers it a priority to increase the share of these software packages. Correlated with the low share of explosive force training is the players' perception of future confrontations, the forms of response to these requests do not include strategies for solving field tasks by using procedures or technical elements that require explosive force, so their tasks have been partially or inefficiently fulfilled. The research showed that jumping on soft surfaces (sand, mattresses) in training lessons for the development of explosive force of the lower limbs are included for 27,29% of subjects and more often included for 0%, this result being only one of the eight sets. The need to work and introduce the training program in the favorable periods of the explosive force training programs for handball players is part of the complex process of achieving sportsmanship and obtaining the desired results in future confrontations.

Introduction: The holistic approach to the educational process involves, in addition to the transmission of theoretical notions, the development of students’ social, emotional and physical skills. These dimensions are fundamental for a healthy and balanced development. In this context, extracurricular activities (EA) at the university level create the premises of an extended framework, in which students explore, cooperate, improve their self-image and achieve better results in exams. In a competence-oriented educational system, EA provide relevant contexts for experiential learning, for character formation and for the development of transversal skills: teamwork, responsibility, communication skills. Unlike curricular activities, which have clearly defined objectives, EA offer students a greater degree of freedom, choice and voluntary involvement, which favors intrinsic motivation and the assumption of an active role in the learning process. Objective: to present the relationship between students’ involvement in EA and different aspects of their lives. Materials and methods: A systematic review of the scientific literature was conducted for 21 articles, selected from the Google Scholar platform, in which the impact/effect of EA on students was presented. Results: Following the analysis, positive correlations were found between the participation of students from different fields in EA and the improvement of indicators such as self-confidence, collaboration, academic performance, etc. Conclusions: The involvement of students in EA is not only a goal of international forums in terms of education, but also represents a way to improve the academic, physical and emotional situation of students.

Background: Academic stress is highly prevalent among healthcare students and is frequently associated with impaired sleep quality and maladaptive eating behaviours. Universities are increasingly recognised as settings that can actively support student wellbeing through curriculum-embedded health practices, giving structured exercise programmes both clinical and educational relevance. Objective: To evaluate the effects of a 7-week kinesioprophylactic exercise programme on perceived stress, sleep quality, and eating behaviour in healthcare students, and to assess its potential as a feasible wellbeing strategy within health-professional curricula. Method: A prospective randomised controlled study with two parallel groups involved 50 second-year students (mean age 20.84 ± 0.61 years), randomly allocated to an experimental group following a supervised 7-week exercise programme (3 sessions/week, 50–60 min each) or a control group maintaining usual lifestyle. Assessments used the PSS-10, PSQI, and DEBQ at baseline and post-intervention. Results: Significant within-group reductions in perceived stress were observed in both groups (p < .001). A significant improvement in sleep quality was found within the experimental group only (p = .016). No significant between-group differences were found at post-test for any outcome. Eating behaviour remained stable across both groups. Adherence was 93%. Conclusions: A short-term kinesioprophylactic programme is feasible, safe, and well accepted by healthcare students, supporting positive trends in stress and sleep outcomes. These findings support embedding structured physical activity within health-professional curricula as part of institutional wellbeing strategies, while underscoring the need for longer interventions, larger samples, and educational outcome measures in future research.

RESUMO Introdução: O teste de força submáxima parece ser válido para prescrever a intensidade nos protocolos de treinamento de força, reduzindo o risco de lesões e duração dos testes. Objetivo: Avaliar a capacidade preditiva dos parâmetros de massa corporal para estimar o exercício de 4-6 repetições máximas (4-6 RM) nos exercícios de Leg press 45°, Chest press e Pull-down efetuados por fisiculturistas. Métodos: Onze fisiculturistas masculinos (38,27 ± 10,48 anos) participaram do estudo. Eles completaram a carga externa incremental até encontrar a carga que lhes permitia realizar de 4 a 6 repetições máximas para cada exercício, em ordem aleatória. A carga inicial foi fixada em 50% da massa corporal para os exercícios de Chest press e Pull-down, e 100% para o de Leg press. O incremento de carga após cada rodada foi de 20 kg para o exercício de membros inferiores e 10 kg em membros superiores. Resultados: Os resultados revelaram que a massa corporal apresenta relações satisfatórias com 4-6 RM para todos os três exercícios. Os resultados mostraram que a massa corporal possui boa capacidade preditiva em todas as três medidas. Conclusão: As equações de previsão sugeridas nesse estudo podem permitir o uso desses exercícios pelos técnicos para medir a performance a 4-6 RM nos exercícios de Leg press 45°, Chest press, e Pull-down. Nível de evidência IV; série de casos.

Background/Objectives: Pediatric thoracic trauma requires prompt stabilization and timely imaging; however, actual sequencing and escalation triggers are infrequently delineated at the pathway level. The aim of this study was to analyze imaging pathways observed in routine clinical practice at our institution and to outline a preliminary escalation framework integrating injury mechanism, clinical severity, and initial ultrasound findings. Methods: A retrospective cohort study was conducted at the “Louis Țurcanu” Clinical Emergency Hospital for Children, Timișoara, Romania, including 66 children admitted with primary thoracic trauma between January 2022 and December 2024. Clinical trajectory markers (transfer-in, ICU admission, length of stay) and imaging utilization/sequencing (FAST, CXR, CT, MRI/CTA) were extracted. We divided injuries into two groups: bony (like fractures of the clavicle or scapula) and non-bony. CT escalation was characterized as a chest CT conducted upon admission. Fisher’s exact and Mann–Whitney U tests were used for comparative analyses. Results: FAST was done on all patients but was infrequently positive. Imaging followed heterogeneous but structured patterns, most commonly FAST with CXR, with or without CT. A large group of them had CT scans without first having any X-rays. CT escalation was associated with fracture-pattern injuries and higher-acuity trajectories (transfer-in and ICU admission), as well as prolonged hospital stays. Pathway-level assessment demonstrated that CT escalation effectively captured bony injury patterns, whereas FAST proficiently sorted ICU-level trajectories. Conclusions: Pediatric thoracic trauma imaging functioned as a selective escalation system: FAST served as a universal bedside entry step, and CT operated as an injury pattern- and acuity-linked severity gate. Making this escalation logic clear may help with standardization while still protecting against radiation.
