- Assessment of heart rate variability and infrared thermography in response to exercise-induced muscle damagePublication . Marques, Wanessa Karoline Brito; Santana, Paulo Vitor Albuquerque; Oliveira, Vinícius Fernandes Ferreira de; Pussieldi, Guilherme de Azambuja; Leite, Luciano Bernardes; Forte, Pedro; Assis, Miller Gomes; Pimenta, Eduardo Mendonça; Mostarda, Cristiano Teixeira; Costa, Herikson Araújo; Dibai-Filho, Almir Vieira; Oliveira Junior, Mario Norberto Sevilio; Cabido, Christian Emmanuel Torres; Veneroso, Christiano EduardoThe aim of this study is to investigate the behavior of autonomic nervous activation and infrared thermography (IR) after an eccentric exercise protocol. The sample consisted of ten physically active men (22.5 ± 3.3 years) who had not practiced plyometric training in the 6 months prior to the study. After a period of familiarization and assessment of body composition, the participants underwent a plyometric jumping protocol, including jumps over a 50 cm obstacle and jumps from a 50 cm box, after a 5-min warm-up on the treadmill. Subsequently, the following assessments were performed: assessments included measures of rating perceived fatigue (RPF), delayed-onset muscle soreness (DOMS), IRT and heart rate variability (HRV) performed at 24, 48 and 72 h after exercise. The RPF results showed a significant increase from baseline at 24 h, 48 h, and 72 h after the muscle damage protocol. For DOMS, significant increases were observed at 24 h, 48 h, and 72 h compared to baseline, with values notably higher at 24 h and 48 h than at 72 h. Thermographic assessments of the posterior thigh region showed a higher concentration of pixels in the warm zone at 48 h and 72 h compared to baseline, as well as at 48 h and 72 h compared to 24 h. Regarding HRV, the LF/HF ratio and %LF were elevated at 24 h and 48 h compared to baseline and 72 h, while %HF decreased at 24 h and 48 h relative to baseline. The exercise-induced stress increased warm-zone pixels and elevated sympathetic activity (LF/HF ratio and %LF) up to 48 h post-exercise. This was followed by a shift to increased parasympathetic modulation (higher %HF), indicating recovery. These findings underscore the utility of IRT and HRV in monitoring recovery and optimizing training.
- Blueberry Extract and Resistance Training Prevent Left Ventricular Redox Dysregulation and Pathological Remodeling in Experimental Severe Pulmonary Arterial HypertensionPublication . Leite, Luciano Bernardes; Soares, Leôncio Lopes; Guimarães-Ervilha, Luiz Otávio; Costa, Sebastião Felipe Ferreira; Generoso, Sara Caco dos Lúcio; Xavier, Mirielly Alexia Miranda; Iasbik-Lima, Thainá; Oliveira, Leandro Licursi; Lucia, Ceres Mattos Della; Bianchi, Sara Elis; Bassani, Valquíria Linck; Herter, Flavio Gilberto; Turck, Patrick; Araujo, Alex Sander da Rosa; Forte, Pedro; Reis, Emily Correna Carlo; Machado-Neves, Mariana; Natali, Antônio JoséTo investigate whether the regular administration of blueberry extract and low-intensity resistance exercise training (RT), either alone or in combination, during the development of monocrotaline (MCT)-induced severe pulmonary arterial hypertension (PAH) in rats protect the left ventricle (LV) from redox dysregulation and pathological remodeling. Groups of seven male Wistar rats were formed for the experiment: sedentary control; sedentary hypertensive; sedentary hypertensive blueberry; exercise hypertensive; and exercise hypertensive blueberry. PAH was experimentally induced through a single intraperitoneal administration of MCT at a dose of 60 mg/kg. One day after injection, the blueberry groups started receiving a daily dose of blueberry extract (100 mg/kg) by gavage, while the exercise groups initiated a three-week program of RT (ladder climbing; 15 climbs carrying 60% of maximum load; one session/day; 5 times/week). Echocardiographic evaluations were conducted 23 days after injection, and the rats were euthanized the next day to harvest LV tissue. Separately, blueberry extract and RT mitigated augments in pulmonary artery resistance, LV tissue redox dysregulation (i.e., increased PC levels) and detrimental remodeling (i.e., reduced inflammation), and reductions in ejection fraction (EF) and fractional shortening (FS) caused by PAH. The combination of treatments prevented reductions in EF and FS, along with the development of a D-shaped LV. blueberry extract and moderate-intensity resistance training administered during the development of MCT-induced severe PAH in rats prevented LV redox dysregulation and pathological remodeling, thereby preserving its function.
- Characterization and Comparison of Athletic Performance and Change of Direction Deficit Across Youth Futsal Age GroupsPublication . Oliveira, João P.; Marinho, Daniel A.; Sampaio, Tatiana; Carvalho, Sílvio; Martins, Hugo; Morais, J. E.Futsal players need peak strength, functional capacity, speed, and explosive lower-limb power for optimal performance. The aim of this study was to (i) characterize and compare anthropometric characteristics, lower limb strength/power, dynamic balance, linear sprint speed, COD performance, and COD deficit across young futsal age groups and (ii) identify key predictors of COD deficit. Methods: Thirty-three male futsal players from three age groups (U13, U15, and U17) were tested. Results: All anthropometric variables showed significant group effects with moderate to strong effect sizes, where U17 presented the largest values, followed by U15 and U13. Strength and power variables presented the same trend. The dynamic balance differed significantly across groups. Significant differences between groups with moderate effect sizes were noted in linear sprints (F = 19.54, p < 0.001, η2 = 0.57), zigzag (F = 19.54, p = 0.002, η2 = 0.35), and COD deficit (F = 19.54, p < 0.001, η2 = 0.46). Post hoc tests revealed that U13 and U15 outperformed U17 in the COD deficit (p < 0.002). The COD deficit showed a quadratic relationship with age, initially improving but later declining in older players (p < 0.001). The body mass and the posteromedial relative difference predicted the COD deficit, with the coefficient of determination (R2) explaining 39% of the COD variance. Conclusions: Coaches and practitioners should utilize COD drills to target various movement patterns and account for pubertal timing, as growth can impact performance
- Characterization of physical performance and change of direction deficit across age groups in young female volleyball playersPublication . Oliveira, João P.; Marinho, D.A.; Jacinto, Pedro; Sampaio, Tatiana; Morais, J. E.Background Volleyball performance relies heavily on agility, strength, and the ability to change direction, yet there is limited research investigating these physical attributes across different age groups in youth volleyball players. The change of direction (COD) deficit—a metric that isolates directional efficiency by comparing agility to linear speed— may provide a more nuanced understanding of an athlete’s movement capabilities. The aim of this study was to investigate: (i) the differences in anthropometrics, lower limb strength/power, dynamic balance, linear sprint speed, and change of direction (COD) ability between young volleyball age groups; (ii) the effect of age on COD deficit in young volleyball players, and; (iii) the COD deficit predictors. Methods A cross-sectional analysis of young volleyball athletes was conducted. Seventy-seven female volleyball players from three age groups (U13:12.43 ± 0.89; U16:14.38 ± 0.52; U18:16.78 ± 0.93) participated in standardized tests measuring their physical qualities. Results The older age groups (U18) were significantly taller, heavier, and faster in linear sprints than their younger counterparts. No significant differences between groups were observed in lower limb strength and power or dynamic balance. The U16 group demonstrated the lowest COD deficit. The regression analysis identified drop jump height (DJ) as the sole significant predictor of COD deficit, explaining 6.9% of the variance (R2 = 0.069, p = 0.033), highlighting its relevance as an indicator of reactive strength. Conclusions These findings suggest that while anthropometric features have increased and sprint performance improved with age, there is no corresponding improvement in lower limb strength, power, or dynamic balance. Drop jump height was the sole predictor of COD deficit, emphasizing the importance of reactive strength in determining agility. Coaches should focus on enhancing lower limb strength and reactive power to optimize COD performance and prevent performance stagnation (training plateaus), particularly in older athletes

Santos, Lucas Vieira; Freitas, Karla Raphaela da Silva Ramos; Pereira, Eveline Torres; Leite, Luciano Bernardes; Forte, Pedro; Oliveira, Claudia Eliza Patrocínio de; Moreira, Osvaldo CostaBackground: Anxiety and depression are prevalent after spinal cord injury, impairing social participation and quality of life. Objective: This study aimed to investigate the effects of traditional resistance training (TRT), flywheel resistance training (FWRT), and high-velocity resistance training (HVRT) on the mental health and quality of life in individuals with spinal cord injury. Methods: Thirty-two participants were divided into TRT (n = 12), FWRT (n = 8), and HVRT (n = 12) groups, undergoing 8 weeks of upper-limb training twice weekly under super-vision. Training intensity and volume were progressively increased. The Hospital Anxiety and Depression Scale and SF-36 Questionnaire were used to assess outcomes. Results: Both the TRT and FWRT groups showed a reduction in HADS-D scores post-intervention (p < 0.001). The TRT group also presented a significant reduction in HADS-A scores post-intervention (p = 0.003). Concerning quality of life, after training, TRT showed improvements in social functioning (p = 0.013), FWRT improved scores in physical functioning (p = 0.002), bodily pain (p = 0.002), vitality (p = 0.046), and role emotional (p < 0.001), while HVRT enhanced role physical (p < 0.001), social functioning (p = 0.013), and role emotional (p < 0.001). Conclusion: Overall, TRT was the most effective in reducing anxiety and depression and enhancing quality of life, while FWRT showed notable gains in physical and functional capacity. HVRT demonstrated improvements primarily in role physical but was less effective in other domains.
- Comparative Efficacy of Bodyweight and Free Weights Training on Shooting Strength in Roller HockeyPublication . Paiva, Eduardo; Afonso, Pedro; Leite, Luciano Bernardes; Teixeira, José Eduardo; Forte, Pedro; Rodrigues, Pedro M.This study evaluated the impact of an 8-week training program on two groups of players, one performing free weights training and the other bodyweight training. The sample consisted of 14 athletes with a mean age of 22.6 years. Assessments of shooting strength were conducted before and after the program, measuring shot speed, acceleration, and strength. The free weights training included exercises with dumbbells and barbells, while the bodyweight training included squats, push- ups, and planks. Sessions occurred twice a week, with gradual progress in the number of sets and repetitions. Statistical analyses were performed using GraphPad Prism software, with significance set at p<0.05. Data distribution was tested using the Shapiro-Wilk test, and comparisons between pre- and post-intervention assessments were made with paired t- tests. Results showed significant improvements in shot speed, acceleration, and strength in the free weights training group, while the bodyweight training group showed no significant changes. It was concluded that free weights training is more effective for improving shooting strength in roller hockey players.
- Effects of theta-binaural beats auditory stimulation on creativity, psychological well-being and mood states of university students: Pilot studyPublication . Mendes, Liliana; Silva, Leonido Levi; Pereira, Antonino; Morgado, ElsaThis study investigates the impact of theta-frequency binaural beats (BB) on creativity, mood, and psychological well-being in university students, addressing the growing interest and controversy surrounding this auditory stimulation technique. A quantitative, correlational, quasi-experimental design was employed, involving 26 university students aged 18–54 (96.2% female, 3.8% male). Participants listened to theta BB (6-Hz beat frequency on a 250 Hz carrier) for 20 minutes daily using the Binaural Beats App. Instruments included a sociodemographic questionnaire, the reduced Creative Personality Scale (EPC), the short Profile of Mood States Questionnaire (POMS), and the Psychological Well-Being Manifestation Scale (EMMBEP). Results revealed significant improvements in creativity, psychological well-being, and reduced total mood disturbance after exposure to theta BB. Significant differences in total mood disturbance across assessment moments highlighted the intervention's time-sensitive benefits. The study highlights the potential of theta-frequency BB to enhance psychological well-being, mood, and creativity among university students. These findings contribute to the growing body of evidence supporting the utility of BB as a non-invasive tool for improving mental and emotional states. Theta BB may serve as an accessible and cost-effective method for promoting mental health and fostering creativity in educational and therapeutic settings.
- Hierarchical clustering of the pre-exam anxiety levels in physically inactive and active adolescent students from 56 countries: an observational study using PISA program dataPublication . Encarnação, Samuel; Teixeira, José Eduardo; Forte, Pedro; Leite, Luciano Bernardes; Sortwell, Andrew; Branquinho, Luís; Ferraz, Ricardo; Afonso, Pedro; Vaz, Paula Marisa Fortunato; Monteiro, António M.The relationship between physical activity and anxiety among students has been extensively studied, with research highlighting the protective effects of physical activity on mental well-being. Methods: This article synthesizes existing literature on the topic and presents a novel analysis of pre-exam anxiety rates among physically inactive high school students from 56 countries. Using data from the Programme for International Student Assessment (PISA) 2018, a hierarchical clustering method was applied to identify four clusters based on strati ed country groups by the students pre-exam anxiety levels. Results: The results indicated ve clusters for low physically active students (three with higher anxiety rates and two with lower levels of the condition) and four clusters for the low physically active individuals (two for higher anxiety rates and two for lower levels). Furthermore, the hierarchical model worked with good precision in the clustering task. In conclusion, considering the low physically active students, Brazil (82%) and the Dominican Republic (81%) recorded the highest pre-exam anxiety levels, while the Czech Republic (35%) had the lowest. Among the physically active students, Malaysia (82%), Brazil (81%), and Costa Rica (81%) recorded the highest anxiety levels, whereas again, the Czech Republic (35%) had the lowest. Discussion: These ndings emphasize that although physical activity generally relates to reduced anxiety, this association varies across cultural and educational contexts.

- I Know What I Have to Do, but I Don’t Do It”: The Relationship Between Knowledge and Adherence to Hand Hygiene in Healthcare SettingsPublication . Silva, Joana; Antunes, Cristina; Batista, Samanta; Braga, José Luís; Gomes, Angélica; Guedes, Rosa; Barbosa, Anabela; Forte, Pedro; Imaginário, CristinaThis study aims to analyze the correlation between healthcare professionals’ knowledge of hand hygiene protocols and their actual adherence to these practices. Specifically, we investigate whether higher knowledge levels correspond to better compliance, and we examine potential influencing factors such as professional role, gender, and prior training in infection control. Methods: A non-probabilistic, convenience sample was composed of 51 healthcare professionals working in patient care. Data collection was conducted through a questionnaire to assess knowledge and direct observation to assess adherence to hand hygiene. Results: The results indicate a satisfactory level of knowledge among healthcare professionals. No statistically significant differences were observed between different professional groups regarding knowledge and adherence to hand hygiene. The average adherence rate to hand hygiene was 60.13%. No statistically significant relationship was found between healthcare professionals’ knowledge and their adherence to hand hygiene. Statistically significant differences were only found between males and females regarding the adherence rate to hand hygiene, with males showing higher adherence. Conclusions: Although healthcare professionals demonstrate satisfactory knowledge about hand hygiene, adherence to the practice still shows variability. Therefore, implementing continuous training programs and developing institutional policies may contribute to improving hand hygiene practices, thereby reducing the incidence of healthcare-associated infections.
