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 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 Two protocols of aerobic exercise modulate the counter-regulatory axis of the renin-angiotensin system.(2020) Magalhães, Daniel Massote; Silva, Albená Nunes da; Rocha, Guilherme Carvalho; Vaz, Lucas Nunes; Faria, Marcelo Henrique Salviano de; Vieira, Erica Leandro Marciano; Rocha, Natalia Pessoa; Silva, Ana Cristina Simões eAims: The renin-angiotensin system (RAS) is a dual system with two opposite arms: i) the classical one formed by the angiotensin converting enzyme (ACE), angiotensin (Ang) II and angiotensin type 1 (AT1) receptors; ii) the counter-regulatory arm consisting of ACE2, Ang-(1–7) and Mas receptor. Physical exercise can modulate this system, however, only animal studies have compared the effects of different intensity protocols on the RAS. No data with humans were provided. Therefore, we investigated the acute effect of two protocols of isowork aerobic exercise [High-Intensity Interval Exercise (HIIE) and Moderate-Intensity Continuous Exercise (MICE)] in plasma and urinary levels of RAS components in physically active men. Main methods: The HIIE protocol included a 5-minute warm-up cycling at 60–70% of heart rate peak (HRp) intensity followed by 10 sets of 30 s above 90% with 1 min of recovery and 3 min of cool down. The MICE protocol was performed at a constant power corresponding to 60–70% of HRp and finalized at the same total work of HIIE. Blood and urine samples were collected before and after the protocols. Plasma and urinary levels of ACE, ACE2, Ang-(1–7) and Ang II were analyzed by enzyme-linked immunoassay. Key findings: While the HIIE protocol significantly increased urinary levels of ACE and plasma levels of ACE2, the MICE protocol elevated urinary concentrations of ACE2 and of Ang-(1–7). A greater increase of urine concentrations of Ang-(1–7) occurred in the MICE if compared with the HIIE protocol. Significance: Aerobic physical exercise acutely increases the activity of the counter-regulatory RAS axis, mostly the MICE protocol.
