Item 10 km running race induces an elevation in the plasma myokine level of nonprofessional runners.(2019) Barbosa, Lucas Soares Marcucci; Martins Junior, Francisco de Assis Dias; Lobo, Lázaro Fernandes; Morais, Mariana Gomes de; Moreira, Janaina Matos; Vieira, Érica Leandro Marciano; Silva, Albená NunesPurpose Acute and chronic physical exercise is believed to have benefcial efects on human health. Exercise is also able to modulate immune function. We hypothesed that exercise is able to induce many benefts for human health by modulating immune functions through the production and release of many myokines. Here, we investigated the efects of a running race on the level of plasmatic myokines. Methods Nine male volunteers took part in this study. Blood samples were obtained before, immediately after and 24 h after the race. Results Participants completed the 10 km running race in 49.85±7.04 min. The levels of IL-6 elevated after exercise (0.94±0.4–2.82±0.3 pg/ml). The IL-15 plasma level was also higher immediately after (0.88±0.25–1.29±0.36 pg/ml), and 24 h after (1.30±1.01 pg/ml), the end of the exercise. Irisin increased only 24 h after exercise (632.60±188.40– 974.70±232.30 pg/ml). FABP3 increased after exercise (829.60±68.93–1306.00±319.10 pg/ml). The plasma levels of BDNF (4719.00±701.80–5557.00±810.30 pg/ml) and Fractalkine increased after exercise (101.2±34.96–134.90±43.62 pg/ ml). The level of FSTL (7265.00±1553.00–9074.00±1662.00 pg/ml) and Osteonectin (16.52±3.54–15.71±3.38 pg/ml) also increased after exercise, and then returned to baseline level 24 h after the end of the session. Conclusion Taken together, these results suggest that a 10 km running race induces elevation of important myokine plasma levels.Item Can creatine supplementation interfere with muscle strength and fatigue in Brazilian National Level Paralympic Powerlifting?(2020) Sampaio, Carlos Rodrigo Soares Freitas; Martins, Felipe José Aidar; Ferreira, Alexandre Reis Pires; Santos, Jymmys Lopes dos; Marçal, Anderson Carlos; Matos, Dihogo Gama de; Souza, Raphael Fabrício de; Moreira, Osvaldo Costa; Guerra, Ialuska; Fernandes Filho, José; Barbosa, Lucas Soares Marcucci; Silva, Albená Nunes da; Almeida Neto, Paulo Francisco de; Cabral, Breno Guilherme de Araújo Tinôco; Reis, Victor MachadoThe aim of the present study was to analyze the effect of creatine (Cr) supplementation on peak torque (PT) and fatigue rate in Paralympic weightlifting athletes. Eight Paralympic powerlifting athletes participated in the study, with 25.40 ± 3.30 years and 70.30 ± 12.15 kg. The measurements of muscle strength, fatigue index (FI), peak torque (PT), force (kgf), force (N), rate of force development (RFD), and time to maximum isometric force (time) were determined by a Musclelab load cell. The study was performed in a single-blind manner, with subjects conducting the experiments first with placebo supplementation and then, following a 7-day washout period, beginning the same protocol with creatine supplementation for 7 days. This sequence was chosen because of the lengthy washout of creatine. Regarding the comparison between conditions, Cr supplementation did not show effects on the variables of muscle force, peak torque, RFD, and time to maximum isometric force (p > 0.05). However, when comparing the results of the moments with the use of Cr and placebo, a difference was observed for the FI after seven days (U3 : 1.12; 95% CI: (0.03, 2.27); p = 0.02); therefore, the FI was higher for placebo. Creatine supplementation has a positive effect on the performance of Paralympic powerlifting athletes, reducing fatigue index, and keeping the force levels as well as PT.Item Physiological and biochemical evaluation of different types of recovery in National Level Paralympic Powerlifting.(2021) Santos, Wélia Yasmin Horacio dos; Martins, Felipe José Aidar; Matos, Dihogo Gama de; Tillaar, Roland van den; Marçal, Anderson Carlos; Lobo, Lázaro Fernandes; Barbosa, Lucas Soares Marcucci; Machado, Saulo da Cunha; Almeida Neto, Paulo Francisco de; Garrido, Nuno Domingos; Reis, Victor Machado; Vieira, Erica Leandro Marciano; Cabral, Breno Guilherme de Araújo Tinôco; Alves, José Vilaça; Silva, Albená Nunes da; Silva Júnior, Walderi Monteiro daBackground: Recovery from training is vital as it ensures training and performance to continue at high intensities and longer durations to stimulate the body and cause further adaptations. Objective: To evaluate different methods of post-workout recovery in Paralympic powerlifting athletes. Methods: Twelve male athletes participated (25.4 ± 3.3 years; 70.3 ± 12.1 kg). The presence of muscle edema, pain threshold, plasma cytokines, and performance measurement were evaluated five times. The recovery methods used in this study were passive recovery (PR), dry needling (DN), and cold-water immersion (CWI). Results: The data analysis showed that the maximal force decreased compared to the pretest value at 15 min and 2 h. The results also revealed that CWI and DN increased Interleukin 2 (IL-2) levels from 24 to 48 h more than that from 2 h to 24 h. After DN, muscle thickness did not increase significantly in any of the muscles, and after 2 h, muscle thickness decreased significantly again in the major pectoralis muscle. After CWI, pain pressure stabilized after 15 min and increased significantly again after 2 h for acromial pectoralis. Conclusion: The strength training sessions generate several changes in metabolism and different recovery methods contribute differently to maintain homeostasis in Paralympic powerlifting athletes.Item A single bout of fatiguing aerobic exercise induces similar pronounced immunological responses in both sexes.(2022) Lobo, Lázaro Fernandes; Morais, Mariana Gomes de; Barbosa, Lucas Soares Marcucci; Martins Junior, Francisco de Assis Dias; Avelar, Luíza Martino; Vieira, Erica Leandro Marciano; Martins, Felipe José Aidar; Wanner, Samuel Penna; Silva, Lucélia Scarabeli; Noman, Maria Clara; Camargos, Bruno Muzzi; Freitas, Kátia Michelle; Gonçalves, William Antonio; Pinho, Vanessa; Silva, Albená Nunes daIntroduction: Physical exercise can acutely and chronically modulate immunological responses. Women and men have different innate and adaptive immune responses, and in this sense, these two groups may also have different acute immunological responses induced by exercise. In addition, it is essential to understand further whether the effects of physical exercise on the immune system responses depend on sex because limited scientific evidence on this topic is available. This information may allow athletes and coaches to improve the training process, mainly to understand if the physiological impact of given training stimuli in women is similar to that in men. Objective: The present study aimed to investigate the acute effects of continuous submaximal exercise until fatigue on physiological and immunological parameters in amateur female and male runners. Methods: This study included 18 female and 15 male volunteers. Each participant visited the laboratory on four consecutive days. The first visit consisted of medical history taking and explaining the study design. On the second visit, the participants were subjected to an incremental test to determine their maximal rate of oxygen consumption (VO2max) that was required to prescribe the intensity of the submaximal exercise protocol. On the third visit, the fatiguing exercise protocol was performed at 77%–80% of the VO2max. During this submaximal exercise, the heart rate, rating of perceived exertion (RPE), and blood lactate were recorded. Blood samples were collected before, immediately after, and 1 h after the fatiguing protocol to analyze the plasma levels of cytokines and creatine kinase (CK) and to count leukocytes. Finally, on the fourth visit, the participants underwent physical evaluations to measure their body composition using dual-energy X-ray absorptiometry (DXA) imaging. Results: The average ages of the female and male groups were 34.2 ± 3.7 and 30.5 ± 4.3 years old, respectively. The female group ran 57 ± 27 min, while the male group ran 52 ± 15 min before fatiguing. In the female group, when comparing before and after the submaximal exercise, marked increases were observed in the following variables: heart rate (from 68.5 to 180.4 bpm), RPE (from 3.6 to 8.2), lactate (from 2.1 to 4.49 mmol/L), and CK (from 89.5 to 126.3 U/L). In addition, the female group showed an increased number of total leukocytes (from 7222.3 to 11162.9 × 106 /μl), neutrophils (from 4,403 to 6,480 × 106 /μl), and lymphocytes (from 2,342 ± to 3,562 × 106 /μl) from pre- to post-submaximal exercise. In the male group, similar elevations in psychophysiological variables were observed, as evidenced by comparing the heart rate (from 52.8 to 184.1 bpm), RPE (from 0.0 to 8.9), lactate (from 2.7 to 7.2 mmol/L), and CK (from 106.2 to 165 U/L) before and after the submaximal exercise. The male group also showed an augmented number of total leukocytes (from 6,245 to 8,050 × 106 /μl), neutrophils (from 3,335 to 4,128 × 106 /), and lymphocytes (from 2,191 to 3,212 × 106 /μl) when comparing pre- and post-submaximal exercise. There were no differences in the changes between women and men for these parameters. Conclusion: The aerobically fatiguing exercise protocol induced pronounced changes in the heart rate, plasma levels of lactate and CK, total leukocyte count, especially the number of neutrophils and lymphocytes, in both sexes. The fatiguing exercise protocol also changed the plasma levels of IL-6 and IL-10 in the female and male groups. Under the present conditions, the physiological changes induced by fatiguing submaximal exercise, including the immunological changes, were not influenced by sex. This study shows that the same aerobic physical exercise can alter immunological parameters in women and men, and this response is similar between sexes.Item Strength training session induces important changes on physiological, immunological, and inflammatory biomarkers.(2018) Fortunato, Ayla Karine; Pontes, Washington Martins; Souza, Débora Maria Soares de; Prazeres, Jéssica Santos Ferreira; Barbosa, Lucas Soares Marcucci; Santos, Júlia Miranda Mól; Vieira, Érica Leandro Marciano; Bearzoti, Eduardo; Pinto, Kelerson Mauro de Castro; Silva, André Talvani Pedrosa da; Silva, Albená Nunes daStrength exercise is a strategy applied in sports and physical training processes. It may induce skeletal muscle hypertrophy. The hypertrophy is dependent on the eccentric muscle actions and on the inflammatory response. Here, we evaluate the physiological, immunological, and inflammatory responses induced by a session of strength training with a focus on predominance of the eccentric muscle actions. Twenty volunteers were separated into two groups: the untrained group (UTG) and the trained group (TG). Both groups hold 4 sets of leg press, knee extensor, and leg curl at 65% of personal one-repetition maximum (1RM), 90 s of recovery, and 2conc/3eccen of duration of execution in each repetition. Blood samples were collected immediately before and after, 2 hours after, and 24 h after the end of the exercise session. The single session of strength training elevated the heart rate (HR), rating of perceived exertion (RPE), visual analog scale (VAS), and lactate blood level in UTG and TG. Creatine kinase (CK) levels were higher at 2 and 24 h after the end of the exercise in UTG and, in TG, only at 24 h. The number of white blood cells (WBC) and neutrophils increased in UTG and TG, post and 2 h after exercise. Lymphocytes increased postexercise but reduced 2 h after exercise in both groups, while the number of monocytes increased only immediately after the exercise session in UTG and TG. The strength training session elevated the levels of apelin and fatty acid-binding proteins-3 (FABP3) in both groups and brain-derived neurotrophic factor (BDNF) in TG. The single exercise session was capable of inducing elevated HR, RPE, lactate level, and CK levels. This protocol changed the count/total number of circulating immune cells in both groups (UTG and TG) and also increased the level of plasmatic apelin, BDNF, and FLTS1 only in TG and FABP3 myokines in both groups.Item The curcumin supplementation with piperine can influence the acute elevation of exercise-induced cytokines : double-blind crossover study.(2022) Castro, Stéfani Miranda; Martins, Felipe José Aidar; Moura, Samara Silva de; Barbosa, Lucas Soares Marcucci; Lobo, Lázaro Fernandes; Martins Junior, Francisco de Assis Dias; Silva Filha, Roberta da; Castro, Pedro Alves Soares Vaz de; Silva, Ana Cristina Simões e; Souza, Danielle da Glória de; Silva, Siomara Aparecida da; Pinto, Kelerson Mauro de Castro; Costa, Guilherme de Paula; Silva, Ana Filipa; Clemente, Filipe Manuel; Pereira, William Valadares Campos; Silva, Albená Nunes daBackground: to evaluate the effects of one week of supplementation with curcumin combined with piperine on physical performance, immune system cell counts, muscle damage, and plasma levels of inflammatory markers after a treadmill running training session. Methods: This study is a double-blind, crossover-balanced clinical trial with a three-week intervention. Sixteen male runners with a mean age of 36 ± 9 years and VO2 max of 60.6 ± 9.03 mL.kg −1 min −1 were recruited and randomly divided into 2 groups: the first group (CPG) was supplemented daily for 7 days with 500 mg of curcumin + 20 mg piperine, and the second group (PG) was supplemented with 540 mg of cellulose. After the 7th day of supplementation, the volunteers participated in the experimental running protocol, where blood samples were collected before, after, and one hour after exercise for analysis of the number of leukocytes, creatine kinase, and cytokine concentration (IL-2, TNF-α, IFN, IL-6, and IL-10) using flow cytometry. This process was repeated, reversing the supplementation offered to the groups. Results: curcumin and piperine supplementation could not change the physical performance, immune cell counts, and muscle damage; however, the aerobic fatiguing exercise protocol inhibited the elevation of the plasmatic levels of some cytokines. The running exercise protocol could elevate the circulating levels of IL-2 (from 49.7 to 59.3 pg/mL), TNF-α (from 48.5 to 51.5 pg/mL), INF (from 128.8 to 165.0 pg/mL), IL-6 (from 63.1 to 77.3 pg/mL), and IL-10 (from 48.9 to 59.6 pg/mL) 1 h after the end of the running protocol. However, the curcumin and piperine supplementation could inhibit this elevation. Conclusions: curcumin and piperine supplementation had no effect on physical performance, immune cell counts, or muscle damage; however, the supplementationItem The effects of strength training session with different types of muscle action on white blood cells counting and Th1/Th2 response.(2019) Barbosa, Lucas Soares Marcucci; Martins Junior, Francisco de Assis Dias; Lobo, Lázaro Fernandes; Morais, Mariana Gomes de; Martins, Felipe José Aidar; Vieira, Erica Leandro Marciano; Silva, Albená Nunes daAim This research investigated the effects of a strength training session with two different types of muscle actions, predominantly concentric or eccentric in the physiological variables, including the counting of white blood cells and inflammatory mediators; and consequently, changes in the Th1/Th2 balance. Methods Twelve healthy adult men performed a strength training session, using two different protocols: predominantly concentric with 5 s of the concentric phase by 1 s of the eccentric phase, and a predominantly eccentric with 1 s of the concentric phase by 5 s of the eccentric phase. Blood samples were collected, before, immediately after and 2 h after the end of the session to analyze subpopulations of white blood cells, creatine kinase (CK), irisin and the levels of anti- and pro-inflammatory mediators. Results Both strength training protocols were able to increase the heart rate, lactate concentration, rate of perceived exertion and the levels of circulating creatine kinase. The predominantly concentric strength training exercises increased the number of total white blood cells, and neutrophils 2 h after the end of the session. The plasmatic levels of interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ), irisin, soluble tumor necrosis factor receptor-1 (sTNFR1) and sTNFR2 did not change after the strength training protocols. Conclusion Therefore, the present study demonstrates that a strength training session is able to disturb the body homeostasis.Item The impact of measures recommended by the government to limit the spread of coronavirus (COVID-19) on physical activity levels, quality of life, and mental health of Brazilians.(2020) Matos, Dihogo Gama de; Martins, Felipe José Aidar; Almeida Neto, Paulo Francisco de; Moreira, Osvaldo Costa; Souza, Raphael Fabrício de; Marçal, Anderson Carlos; Barbosa, Lucas Soares Marcucci; Martins Junior, Francisco de Assis Dias; Lobo, Lázaro Fernandes; Santos, Jymmys Lopes dos; Guerra, Ialuska; Silva, Anselmo de Athayde Costa e; Neves, Eduardo Borba; Cabral, Breno Guilherme de Araújo Tinôco; Reis, Victor Machado; Silva, Albená Nunes daTo reduce transmission of the coronavirus, the Brazilian government adopted containment measures to control the virus’ spread, including limitations to the practice of physical activity. It was aimed to analyze the effects of COVID-19 quarantine on physical activity levels, energy expenditure, quality of life, and level of stress in a sample of the Brazilian population. The sample included 426 participants (7 to 80 years). The International Physical Activity Questionnaire, Short form survey-36 (SF-36), and Stress Perception Scale, were used to assess the level of physical activity, quality of life and stress, respectively. The anthropometric data was used to the assessment of body mass index and basal metabolic rate. Body weight increased significantly in all sample (p < 0.05). During the pandemic, 84% of the sample indicated a low level of physical activity. Furthermore, weekly energy expenditure decreased significantly in all age groups during the pandemic (children p < 0.0001; adolescents: p < 0.0001; adults p < 0.001, and elderly p < 0.0001). All aspects of quality of life, significantly reduced in both sexes in all age groups (p < 0.05). With the exception of children, stress levels increased significantly during the pandemic (adolescents: male: p = 0.003, female: p < 0.05; adults: male: p = 0.003, female: p = 0.01, and elderly: male: p = 0.02, female: p = 0.03). Findings from the present study suggests that COVID-19 social isolation has negatively affected Brazilian’ physical activity and quality of life.
