- Acute Effects of Nitrate-Rich Beetroot Juice on Cardiovascular and Hemodynamic Responses to Flywheel Resistance Exercise: A Randomized, Double-Blind, Placebo-Controlled Crossover TrialPublication . Primo, Mateus Chaves; Viana, Ítalo Santiago Alves; Goulart-Silva, Leonardo Silveira; Machado, Wanderson Matheus Lopes; Leite , Luciano Bernardes; Forte, Pedro; Calhelha, Ricardo C.; Monteiro, António M.; Branquinho, Luís; Silva, Sandro Fernandes; Oliveira, Claudia Eliza Patrocínio de; Moreira, Osvaldo CostaBeetroot juice is a popular nutritional resource in sports due to its ergogenic effects, promoting vasodilation, hypotension, improved energy efficiency, and reduced oxygen cost. However, its role in modulating the autonomic nervous system during strength training remains understudied. This study assessed the effects of acute nitrate-rich beetroot juice supplementation on cardiovascular and hemodynamic responses to flywheel resistance exercise. Fifteen male participants (age 22 +/- 3.64 years) from the Federal University of Vi & ccedil;osa completed a crossover, double-blind, placebo-controlled trial. Each participant consumed either 400 mg of standardized nitrate or a placebo before performing 4 sets of 8-12 repetitions at 100% of their maximum concentric strength using a leg extension exercise, with 90 s recovery intervals. Heart rate, blood pressure, oxygen saturation, and subjective perception of effort were measured after each set. Data were analyzed using SPSS 23, employing the Shapiro-Wilk normality test, t-test for related samples, and MANOVA with time and supplement factors. NO3- supplementation led to a smaller increase in systolic blood pressure (SBP) during exercise compared to the placebo and reduced diastolic blood pressure (DBP) in the last set, reflecting decreased peripheral vascular resistance. However, no significant effects were observed for heart rate, rate-pressure product, oxygen saturation, time under tension, or subjective perception of effort. These findings suggest that NO3- supplementation can offer cardiovascular benefits by attenuating blood pressure increases during strength training, highlighting its potential as a low-risk ergogenic aid for healthy young men.
- Agreement Between a Wristwatch and a Free Optical Sensor with a Chest Strap in Measuring HR Variations During Front Crawl SwimmingPublication . Bartolomeu, Raúl Filipe; Silva, Vasco; Pereira, Ana; Morais, Gonçalo; Sokołowski, Kamil; Strzała, Marek; Morais, Jorge; Teixeira, José EduardoWearables with optical sensors for heart rate (HR) measurement are widely available in the market. However, their accuracy in water is still underexplored. The aim of the present study was to test the agreement of two different devices for HR monitoring with a chest strap while swimming at different intensities. Twenty male and ten female subjects (mean 19.6 ± 0.7 years old, 173.3 ± 5.4 cm, and 67.1 ± 6.6 kg) performed an intermittent progressive protocol of 3 × 30 s tethered front crawl swimming followed by a 1 min rest period. A chest strap, a wristwatch, and a multi-site optical sensor placed at the temple were used simultaneously. A strong association, an excellent intra-class correlation, and a low mean bias were denoted (R2 = 0.85, ICC = 0.94, b = −1) between HRchest vs. HRtemple. Both indicators increased throughout the test, denoting an increase in accuracy from light to vigorous exercise intensity. HRchest and HRwatch showed a moderate association for the whole test (R2 = 0.23) but a weak association, a poor consistency, and a high mean bias stepwise (0.01 ≤ R2 ≤ 0.06, 0.03 ≤ ICC ≤ 0.42, −48.1 ≤ b≤ −16.1). During swimming, the HR values from the temple showed a better agreement with the chest strap than those from the wristwatch. The temple reading accuracy might be enhanced by using the device during the dryland warm-up routine.
- 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.
- Associations Between Pain Intensity and Inflammatory Profile in Women with Android and Gynoid Obesity Diagnosed with Chronic Pain: An Observational StudyPublication . Cota, Cecília Cristina; Miranda-Castro, Stefani; Souza-Gomes, Antônio Felipe; Leite, Luciano Bernardes; Forte, Pedro; Monteiro, António M.; Pereira, William Valadares Campos; Moura, Samara Silva; Nunes-Silva, AlbenáThere are different types of obesity, and the metabolic conditions associated with these phenotypes are also heterogeneous. Overweight and obesity are not only associated with pain but are also identified as risk factors for the development of pain. Objective: This study aimed to compare the levels of inflammatory biomarkers, counting of immune cells, and chronic pain between android and gynoid female patients with obesity. Method: Thirty (n = 30) women took part in this study (18 androids, age: 50.61 +/- 9.41 and 12 gynoids, age: 50.67 +/- 9.45). The participants underwent anamnesis, Visual Numeric Scale (VNS), dual-energy X-ray absorptiometry, and blood sampling for the analysis of leukocytes, C-reactive protein (CRP), and interleukin (IL)-6. Results: The number of total leukocytes in the blood was not different when comparing the android group (6045 mu L) with the gynoid group (5230 mu L). No differences were observed for neutrophils (3440 mu L in android and 3017 mu L in gynoid), lymphocytes (2208 mu L in android and 2115 mu L in gynoid), for monocytes (429.7 mu L in android and 392.8 mu L in gynoid), and basophils (17.27 mu L in android and 15.41 mu L in gynoid). However, there was a significant difference between the number of eosinophils when comparing the android group (137.6 mu L) with the gynoid group (204.9 mu L), p = 0.04. Although both groups presented CRP values above 0.3 mg/dL-indicative of low-grade inflammation-no statistically significant difference was observed. Similarly, no difference was found in pain intensity between groups, as measured by the Visual Numeric Scale (VNS). Conclusions: Although most inflammatory and pain markers did not differ between groups, the higher eosinophil count in the gynoid phenotype suggests immunological distinctions between obesity types. These findings underline the importance of considering body fat distribution in clinical assessments of inflammation and chronic pain in women with obesity.
- Beyond the Gym Floor and the Classroom: Physical Education as a Catalyst for Transdisciplinary Physically Active Learning in the Portuguese Educational LandscapePublication . Santos, Artur Jorge; Baptista, Liliana; Amoroso, José; Furtado, Guilherme; Teixeira, Manuela; Lima, Carla Pedroso deThis chapter explores the transformative potential of physical education (PE) when integrated into a transdisciplinary and physically active learning (PAL) framework. By moving beyond the traditional confines of the gym and classroom, we examine how PE can serve as a core component of holistic education. The chapter delves into the theoretical underpinnings of transdisciplinary and active learning, highlighting their alignment with the goals of PE. It will provide practical examples and strategies for implementing transdisciplinary PE programs, emphasizing collaboration with other subject areas and the creation of authentic learning experiences. The chapter will also discuss the role of PE in fostering critical thinking, problem-solving, and creativity, while promoting physical literacy and well-being. Ultimately, this chapter aims to inspire educators to reimagine PE as a dynamic and essential component of a comprehensive curriculum.
- 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.
- Can physical exercise modify intestinal integrity and gut microbiota composition? A systematic review of in vivo studiesPublication . Pereira, Stephanie Michelin Santana; São José, Vinicius Parzanini Brilhante de; Silva, Alessandra da; Martins, Karina Vitoria Cipriana; Leite , Luciano Bernardes; Forte, Pedro; Natali, Antônio José; Martino, Hércia Stampini Duarte; Lucia, Ceres Mattos Della; Bressan, JosefinaThere is little evidence about how physical exercise affects the gut microbiota since studies in the field are relatively recent. Thus, we aimed to systematically review the main effects of regular physical exercise on the intestinal integrity and microbiota composition in animal models, discuss the mechanisms involved, and indicate future directions. Searches for original articles were performed in PubMed/MEDLINE, Scopus, Web of Science, and Embase. A total of 18 studies were selected. These studies suggest that physical exercise has a significant impact on the gut microbiota. Voluntary running increased the thickness of duodenal villi and microbiota diversity but reduced its richness. Low-intensity treadmill running increased the abundance of the phylum Actinobacteria and the family Bifidobacteriaceae, while that of moderate-intensity reduced the Bacteroides/Prevotella ratio. High-intensity swimming and treadmill running altered the gut microbiota, evidenced by beta-diversity, and increased the Shannon and Chao indices but reduced short-chain fatty acids. Resistance exercise increased the Chao index and altered the functionality of the gut microbiota, increasing carbohydrate metabolism and reducing lipid and amino acid metabolism. Thus, regular physical exercise of different intensities and types can modify the gut microbiota, and the exercise benefits appear to be positively associated with training intensity.
- Can the Digital Skills of Higher Education Students Improve as They Progress Through Their Studies?Publication . Patrício, Maria Raquel; Gonçalves, Bruno F.; Gonçalves, VítorIn recent years, there has been growing concern within the academic and scientific communities regarding the digital skills of teachers. However, it is our belief that the digital skills of students have been somewhat overlooked. We assert that it is not sufficient for teachers to possess digital skills in various areas; it is equally vital for students to develop and enhance their digital skills. This is essential for ensuring that the learning process is innovative, dynamic, and reflective of reality. Consequently, there has been a need to explore the digital skills of students in higher education. This article aims to present the findings of a questionnaire survey assessing the level of digital competence of students at the School of Education of the Polytechnic Institute of Bragança (Portugal). The questionnaire was adapted from the European Digital Competence Framework for Citizens (DigComp 2.2). The results were analyzed based on the students’ level of study (Higher Professional Technical Course, Bachelor’s Degree, and Master’s Degree) and their level of digital proficiency (basic, intermediate, advanced, and highly specialized) to identify differences and similarities among the students. The results indicate that students at all three academic levels generally perceive themselves to possess an intermediate level of digital proficiency. Therefore, it is essential that students improve their digital skills to reach the highest level of digital proficiency.
- Case Report: Case study of 100 consecutive IRONMAN®-distance triathlons—impact of race splits and sleep on the performance of an elite athletePublication . Knechtle, Beat; Leite , Luciano Bernardes; Forte, Pedro; Andrade, Marilia Santos; Cuk, Ivan; Nikolaidis, Pantelis Theo; Scheer, Volker; Weiss, Katja; Rosemann, ThomasLong-distance triathletes such as IRONMAN (R) and ultra-triathletes competing in longer race distances continue to extend ultra-endurance limits. While the performance of 60 IRONMAN (R)-distance triathlons in 60 days was the longest described to date, we analysed in the present case study the impact of split disciplines and recovery in one athlete completing 100 IRONMAN (R)-distance triathlons in 100 days. To date, this is the longest self-paced world record attempt for most daily IRONMAN (R)-distance triathlons.To assess the influence of each activity's duration on the total time, the cross-correlation function was calculated for swimming, cycling, running, and sleeping times. The autocorrelation function, which measures the correlation of a time series with itself at different lags, was also employed using NumPy.The moving average for swimming slightly increased in the middle of the period, stabilizing at similar to 1.43 h. Cycling displayed notable fluctuations between similar to 5.5 and 7h, with a downward trend toward the end. The moving average for running remains high, between 5.8 and 7.2 h, showing consistency over the 100 days. The moving average for total time hovered at similar to 15 h, with peaks at the beginning, and slightly declined in the final days. The cross-correlation between swimming time and total time showed relatively low values. Cycling demonstrated a stronger correlation with total time. Running also exhibited a high correlation with total time. The cross-correlation between sleep time and swimming time presented low values. In cycling, the correlation was stronger. For running, a moderate correlation was observed. The correlation with total time was also high. The autocorrelation for swimming showed high values at short lags with a gradual decrease over time. For cycling, the autocorrelation also began strong, decreasing moderately as lags increased. Running displayed high autocorrelation at short lags, indicating a daily dependency in performance, with a gradual decay over time. The total time autocorrelation was high and remained relatively elevated with increasing lags, showing consistent dependency on cumulative efforts across all activities. In a triathlete completing 100 IRONMAN (R)-distance triathlons in 100 days, cycling and running split times have a higher influence on overall times than swimming. Swimming performance is not influenced by sleep quality, whereas cycling performance is. Swimming times slowed faster over days than cycling and running times. Any athlete intending to break this record should focus on cycling and running training in the pre-event preparation.
