Dos Santos, WM, Tavares Junior, AC, Braz, TV, Lopes, CR, Brigatto, FA, and Dos Santos, JW. Resistance-trained individuals can underestimate the intensity of the resistance training session: An analysis among genders, training experience, and exercises. J Strength Cond Res 36(6): 1506-1510, 2022-Resistance training (RT) promotes improvements in healthy parameters for young to elderly adults and athletes' performance. Strength and muscle mass improvements are dependent on exercise intensity. This study verifies whether 53 healthy young adults underestimate exercise intensity in 3 different exercises, such as bench press (BP), biceps curl (BC), and leg press 45° (LP). Researchers asked the subjects "How much load do you use to perform 10 repetitions in this exercise usually in workout routines?" in each exercise. Individuals warmed up and then performed as many repetitions as possible until they reached the concentric failure. Deviations from data normality were found by using Levene's test; the number of repetitions per exercise within sex was tested by using Friedman's test and Conover's post hoc and Kruskal-Wallis tests to compare the number of repetitions between sex and RT experience. We correlated the number of repetitions and training experience using the Spearman test. The number of repetitions for both groups (male and female) is greater than 8-12 repetitions for BC and LP and BP of the female group, except for men who perform around 8-12 repetitions on BP. Frequency of maximal repetitions reached for 8-12 repetitions for women was 12% for BP, 28% for BC, and 28% for LP. The frequency men reached was 46.5% for BP, 14.3% for BC, and 14.3% for LP. Training experience did not influence the number of repetitions reached. Resistance training practitioners underestimate exercise load (56% of total sample) to be independent of experience. Women underestimate exercise load more than men. Based on the present results, it is possible to state that RT should not be prescribed considering a predefined number of repetitions and a linked percentage of loads, without the guidance for frequent adjustments of loads, according to the exercise performed.

Introdução: Estudos mostram que o uso crônico de substâncias psicoativas está associado com redução na função cognitiva, além de afetar de forma negativa a regulação emocional reforçando o comportamento para o uso de drogas. Objetivo: analisar o efeito agudo de uma partida de futsal sobre o estado de humor e na função cognitiva em indivíduos toxicodependentes, atendidos no CAPS-ad. Métodos: Os participantes foram divididos em dois grupos, Grupo controle (n = 10) e Grupo futsal (n = 10). Para a avaliação do estado de humor foi utilizado à escala de humor de Brunel e o teste de cubos de Corsi para a memória de trabalho visuespacial. Resultados: Na análise intergrupos pós-intervenção, verificou-se redução dos fatores raiva (p = 0,008), depressão (p = 0,005) e tensão (p = 0,009). Já na análise intragrupos, o grupo futsal apresentou redução dos fatores raiva (p = 0,03), depressão (p = 0,007) e tensão (p = 0,01) evidenciando mudança no estado de humor. Em relação à memória operacional, houve um aumento na quantidade de blocos recordados (p = 0,0002) na análise intergrupos e intragrupo (p = 0,01) no grupo futsal. Conclusão: A realização de uma partida de futsal utilizada como uma estratégia não farmacológica no tratamento de dependentes químicos foi capaz de modular de forma positiva o estado de humor e a função cognitiva destes sujeitos. No entanto, o jogo de futsal ainda precisa ser mais estudado como opção de conteúdo em um programa de atividade física regular para o tratamento de dependentes químicos.

The primary aim of this study was to compare the measured oxygen consumption (Measured-VO2) in a simulated futsal game (S-Game) with the estimated oxygen consumption (Estimated-VO2) through a regression equation between heart rate (HR) and oxygen consumption (VO2) (HR-VO2) in treadmill running, and a secondary aim was to calculate the total energy expenditure (EE) in S-Game. Ten professional players (22.20 ± 3.22 years) were evaluated. HR-VO2 was determined individually in the continuous test on the treadmill (ContTest). The Measured-VO2 in S-Game was compared with the Estimated-VO2 in the ContTest. Alactic and lactic pathways were estimated by VO2. The Estimated-VO2 presented no statistically significant difference with the Measured-VO2, using the paired t-test (p = 0.38). However, the correlation between Estimated- and Measured-VO2 was very weak (r = −0.05), and it presented poor agreement (concordance correlation coefficient = −0.04). In addition, a Bland–Altman plot presented bias of −2.8 ml/kg/min and individual difference as large as 19 ml/kg/min. The HR-VO2 determined by the ContTest was not a good individual predictor of VO2. The high intensity and intermittent nature of the futsal game possibly caused dissociation in the HR-VO2 relationship. ContTest is not recommended for estimating VO2 and calculating individual EE in the futsal game. This is recommended only for the group mean. The total EE in S-Game was 13.10 ± 1.25 kcal.min−1 (10.81 ± 1.57 metabolic equivalents). The contributions from the metabolic pathways were as follows: aerobic (93%), alactic (5%), and lactic (2%).

No. of bitstreams: 0 Previous issue date: 2020-12-14 Physiological responses in futsal have not been studied together with temporal information about the players’ stay on the court. The aim of this study was to compare heart rate (HR) and blood lactate concentration ([La−]) responses between 1-H and 2-H considering the time of permanency of the players on the court at each substitution in a futsal match. HR was recorded during entire match and [La−] was analyzed after each substitution of seven players. %HRmean (89.61 ± 2.31 vs. 88.03 ± 4.98 %HRmax) and [La−] mean (8.46 ± 3.01 vs. 8.17 ± 2.91 mmol·L−1) did not differ between 1-H and 2-H (ES, trivial-small). Time in intensity zones of 50–100 %HRmax differed only in 60–70 %HRmax (ES, moderate). HR coefficient of variation throughout the match was low (7%) and among the four outfield players on the court (quartets, 5%). Substitutions (2 player’s participation in each half), time of permanence on the court (7.15 ± 2.39 vs. 9.49 ± 3.80 min), ratio between time in- and out-ratio on the court (In:Outcourt = 1:1.30 ± 1:0.48 vs. 1:1.05 ± 1:0.55 min) also were similar between 1-H and 2-H (ES, moderate and small, respectively). Balancing the number of substitutions, and the In:Outcourt ratio of players in both halves of the match, playing lower time at 1-H, ~8 min for each participation in the match, made it possible to maintain intensity of the match in 2-H similar to the 1H. These results are a good guidance to coaches and for application in future studies.

No. of bitstreams: 0 Previous issue date: 2017-02-01 The training load imposed and perceived by coaches and soccer players, respectively, was compared for three weeks of the basic preparatory period of a professional soccer team through session ratings of perceived exertion (S-RPE). Participants were 24 professional Brazilian soccer players (all males, age: 24.1 ± 3.4 years) and their coaches. Athletes responded to the scale of perceived exertion (scores from 0 to10) after the training, while the coaches completed the scale prior to the training session, based on prior planning. The t-test for independent samples was used to compare S-RPE responses, and the Pearson correlation test was used to examine possible correlations between the parameters analyzed. There were no statistical differences between perceptions of prescribed (coaches) and experienced (players) S-RPE, and moderate correlations were found between these parameters (r =.60; p =.003). No statistically significant group differences were found in the perceived exertion during any of three types of training: physical, technical, or tactical. The results suggest that the S-RPE prescribed during the preseason period (by coaches) was not different from that perceived by professional soccer players.

The enriched environment (EE) is a combination of stimulations inserted in the cage, such as tunnels, exercise wheel and color objects, increased cage size and the number of rats. Although the EE can be promoter of physical activity (PA), the literature lacks studies showing the effects of this accumulation of PA in the rats. In this way, the present study aims to investigate the effects of EE on maximal lactate steady state in rats. To this, adult Wistar rats were randomly distributed into control group (CG), kept in conventional cages, and EE group (EEG), kept in enriched cages. Before and after the experimental period (six weeks) the animals were submitted for the maximal lactate steady state (MLSS) test. In the last week, length and body mass was measured. At the end of the experimental period, after euthanasia, blood sample was collected for the analyses of glucose and heart was weighted. To statistical analyses, after the test of normality, the parametric results were analyzed by Student's t test and nonparametric through Mann-Whintey test. There were no differences in serum glucose, body length, body and heart mass. The groups presented similar MLSS at beginning of experiment, however, MLSS load was higher in EE than CG at end of experiment. In conclusion, PA performed in the enriched cage increased the aerobic capacity in comparing to the conventional cage, even in the absence of significant changes in length and body weight and blood glucose.

The aim of this study was to verify the accuracy and reliability of determining the displacement of Wistar rats by means of videogrammetry software Dvideo. The accuracy (between the known distance and distance traced) was determined by 3 different evaluators twice consecutive, by videoing a course of 10 meters in the enriched environment together with further analysis of the displacement of the midpoint marked on an apparatus. To calculate reliability (accuracy of the measurement system) and reproducibility (precision of the evaluators) to obtain the ratio of precision to tolerance (P/T), eight animals were filmed for 10 minutes in the enriched environment and analysis of distance covered by one of the animals by three different reviewers thrice consecutive.Results The results obtained in the course of 10 meters of the known distance demonstrated accuracy of 0.10 m, precision of 0.05 m, and bias of 0.07 m. In the reliability test during the 10 minutes of displacement (m) of animal, the ratio of precision to tolerance (P/T) = 0.1 m was found between three different evaluators, demonstrating adequate capacity of the measure.Conclusion The manual tracking mode of the Dvideo presented high reliability and it can be employed for the displacement analysis of studies with rat experimental models.

The aim of this study was to establish the validity and reliability and verification of the reproducibility of the lactate minimum test (LM) to predict the maximal lactate steady state exercise intensity (MLSS) on a futsal-specific circuit (Futsal_circuit) which takes into consideration the technical movements performed. 16 male Brazilian futsal players (body mass: 67.7±8.3 kg; height: 1.73±0.05 m) were distributed randomly into 2 studies with 8 athletes in each (Study A – reproducibility; Study B – validity). First, aerobic capacity was determined by adapting the protocol of the LM to the futsal_circuit. In study A, the evaluation was repeated after 7 days (test e re-test) and, in study B, the MLSS on the futsal_circuit was performed. LM intensity (test=7.7±0.3 km.h-1; retest=7.7±0.4 km.h-1) showed a concordance (CV=4.13 and ET=0.32) on study A. No significant differences, high association (r=0.80; p

ABSTRACT Introduction: There is a high prevalence of youth that not meet the health criterion for cardiorespiratory fitness, which exposes them to risks related to metabolic, cardiovascular and mental health. Thus, it is relevant to investigate which aspects are associated with cardiorespiratory fitness in youth. Objective: To analyze the factors associated with cardiorespiratory fitness in school students. Methods: Cross-sectional study involving 736 students (50.1% female) with age between 10 and 18 years. The following has been analyzed: the socioeconomic condition, paternal education, number of siblings, physical activity perception, moderate to vigorous physical activity, participation in physical education classes, sport practice, place to practice, active transport and sedentary behavior. Height and body mass were measured and a cardiorespiratory fitness test was performed. Prevalence ratio (PR) and 95% confidence intervals were estimated using the Poisson regression. Results: For students aged less than 14 years, variables that presented association with cardiorespiratory fitness were female sex (PR = 0.79, 0.68-0.91), overweight (PR = 0.73, 0.61-0.89), physical activity perception equal to persons of the same age (PR = 1.26, 1.03-1.53), weekly physical activity 3-6h (PR = 1.21, 1.05-1.38), participation in physical education classes (PR = 1.35, 1.03-1.76), and sedentary behavior ≥ 2h (RP = 0.82, 0.73-0.94). With respect to students aged 14 years or more, female sex (PR = 0.35, 0.19-0.63), overweight (PR = 0.25, 0.09-0.66), practicing sports a few times (PR = 1.96, 1.00-3.81) and frequently (PR =2.09, 1.01-4.31) presented association with cardiorespiratory fitness. Conclusion: Intervention programs aiming at increasing health criterion requirement for cardiorespiratory fitness of students should promote moderate to vigorous physical activity, sport practice, participation in physical education classes and overweight reduction.

Vinte e oito meninos (9,47 ± 0,64 anos) e 30 meninas (9,69 ± 0,70 anos) foram avaliados. Os valores de correlação entre a agilidade, velocidade de 5, 10 e 25 m foram, respectivamente, r = 0,63, 0,51, 0,44 e 0,64 com o salto vertical, r = 0,68, 0,62, 0,28 e 0,62 com o salto sêxtuplo, e r = 0,60, 0,50, 0,26 e 0,57 com o salto horizontal. O salto vertical e o salto sêxtuplo foram capazes de predizer o desempenho da agilidade e da velocidade de 25 m (p < 0,05). Além disso, demonstraram capacidade de predizer a velocidade de 5 e 10 m, respectivamente (p < 0,05). Os testes de salto vertical e sêxtuplo podem ser utilizados para avaliação e controle do treinamento com crianças praticantes de atividades que demandam agilidade e velocidade, uma vez que ambos os saltos predisseram o desempenho da agilidade e velocidade, o que não ocorreu com o salto horizontal. The aim of the present study were: 1) To verify the relationship of vertical, horizontal and sextuple jumps with agility and velocity of 5, 10 and 25 m; 2) To verify the capacity of these jumps to predict the agility and 5, 10 and 25 m velocity performance in children. Twenty eight boys (9.47 ± 0.64 years) and thirty girls (9.69 ± 0.70 years) were evaluated. The correlation values between agility and velocity on 5, 10 and 25 m velocity were, respectively, r = 0.63, 0.51, 0.44 and 0.64 with vertical jump, r = 0.68, 0.62, 0.28 and 0.62 with sextuple jump, and r = 0.60, 0.50, 0.26 and 0.57 with horizontal jump. The vertical and sextuple jumps were able to predict the agility and 25 m velocity performance (p < 0.05). Furthermore, they demonstrated capacity to predict 5 and 10 m velocity, respectively (p < 0.05). The vertical and sextuple jump tests may be used for assessment and control of training with children practicing activities that require agility and velocity, since both jumps predicted the agility and velocity performance, which did not occur with the horizontal jump.

O desempenho tático de equipes vitoriosas e derrotadas foi comparado através do Sistema de Avaliação Tática no Futebol (FUT-SAT). Três mil, oitocentos e dez ações táticas foram realizadas por 72 jogadores das categorias sub- 11 (n=12), sub-13 (n=12) sub-15 (n=30) e sub-17 (n=18), de diferentes clubes portugueses. Vinte e quatro equipes foram compostas para a análise, cada equipe disputou um jogo (12 jogos analisados). Cada equipe foi composta por três jogadores de linha, mais o goleiro, não analisado no teste. A análise estatística foi realizada através do software SPSS 17.0 for Windows. Uma análise descritiva e os testes de KolmogorovSmirnov, Qui-quadrado, Mann-Whitney U e o T-teste para amostras independentes foram realizados, e o teste Kappa de Cohen para determinação da confiabilidade da amostra. Considerando 76 variáveis analisadas, 12 apresentaram diferenças significantes entre os jogadores das equipes vitoriosas e derrotadas.

The aim of study was to verify what tactical behaviors differ winner from loser teams in small sized games in youth soccer players. The tactical performance of winners and losers teams was compared through of System of Tactical Assessment in Soccer (FUT-SAT). Three thousand eight hundred and eight tactical actions were carried out by seventy-two youth soccer players from the under-11 (n=12), under-13 (n=12), under-15 (n=30) and under-17 (n=18) categories of Portuguese teams. Twenty four teams were composed to analyze, each team carried out one match (12 match analyzed). Each team was composed by three line players with goalkeeper which was not analyzed in test. The statistical analysis was performed thought the SPSS 17.0 software for Windows. A descriptive analyze and the KolmogorovSmirnov, Chi-square, Mann-Whitney U and T-Test tests to the independent samples was carried out, and the Cohen’s Kappa test to determining of the sample reability. Considering 76 variables analyzed, 12 presented significant differences among players of winners and loses teams. The players of the winner teams presented superiority in Macro-Category Action, in the Defensive tactical principles, Equilibrium and Defensive Unity. In the category Local of action in the Field, the winner teams presented superiority in the number of defensive actions performed in the defensive midfielder. In the category Result of the action, the variables Keep without the ball, Retrieving the ball possession and Shots on goal the winner teams presented higher results, while in variables Losing the ball possession and Suffering shot on goal the loser teams presented higher results. In the Performance Macro-Category, the superiority of the winners was showed by better Tactical Performance Index (TPI) in the Penetration principles, Offensive Unity, and in the Offensive phase of the game. The results demonstrated that the winner players presented superiority in both stages of the game.

No. of bitstreams: 0 Previous issue date: 2012-05-01 Although dynamic and stretching exercises have been widely investigated, there is little information about warm up performed by tag games. Thus, the purpose of the present study was to verify the acute effect of dynamic exercises compared to a tag game warm up on agility and vertical jump in children. 25 boys and 24 girls participated in this study and performed the agility and vertical jump tests after warm up based on dynamic exercises or as a tag game lasting 10 min each in two different days randomly. Dynamic exercises warm up consisted in a run lasting 2.5 min followed by 2 series of 8 dynamic exercises lasting 10 seconds each interspersed with 20s of light run to recovery. Tag game warm up was performed by a tag game with two variations lasting 5 min each. The first variation there was a single cather, which aimed to get the other participants by touching hands. In the second part of the game, the rules were the same except that the participant that was caught had to help the catcher forming a team of catchers. Warm up intensity was monitored by OMNI perceived exertion scale. ANOVA 2x2 for repeated measures (Warm up x Sex) demonstrated no significant differences between dynamic exercises and tag game for agility and vertical jump (P>0.05) for boys and girls. Perceived exertion was significantly higher in tag game compared to dynamic exercises on girls (P

Ratos Wistar jovens foram divididos em dois grupos de acordo com a dieta: controle (C) (dieta padrão) e espirulina (S) (dieta à base de espirulina). Ao final do período experimental (cinco semanas) os animais foram submetidos a uma sessão aguda de exercício de natação (20 minutos, suportando sobrecarga equivalente a 5% do peso corporal) para avaliação do lactato sanguíneo, glicose, insulina, proteínas, albumina e ácidos graxos livres (AGL) séricos. Amostras do músculo gastrocnêmio e fígado foram utilizadas para determinação dos teores de glicogênio e lipídeos. Ambos os grupos C e S apresentaram aumento da glicemia e dos AGL, queda da insulinemia e redução dos teores de glicogênio muscular e hepático pós-exercício. A lactacidemia durante o exercício foi superior no grupo S em relação ao C. Conclui-se que o padrão de respostas ao exercício agudo dos grupos C e S foi semelhante. Contudo, a proteína da dieta pareceu influenciar aspectos do metabolismo glicídico. In this study we compared the metabolic response to acute exercise among rats fed on a standard diet or on a spirulina diet. Young Wistar rats were divided into two groups according to diet: control (C) (standard diet) and spirulina (S) (spirulina diet). At the end of experimental period (5 weeks) rats were submitted to an acute exercise session of swimming (20 minutes, supporting a load corresponding to 5% of body weight) to determine blood lactate and serum glucose, insulin, proteins, albumin and fatty free acids (FFA). Gastrocnemius and liver samples were used to determine glycogen and lipids tenors. Both C and S groups showed increase in serum glucose and FFA, a drop in serum insulin and a decrease of muscle and liver glycogen contents after acute exercise. Blood lactate during exercise was higher in S than C rats. It was concluded that the response pattern to acute exercise was similar for C and S rats. However, diet protein seemed to influence aspects of glucose metabolism.

Las muestras del músculo gastrocnemio y fígado fueron utilizadas para la determinación de los tenores de glicogeno y de lípidos. Ambos grupos C e S presentaron un aumento de la glicemia y de los AGL, mantenimiento de la insulinemia y reducción de los tenores de glicogeno muscular y hepático post-ejercicio. La lactacidemia durante el ejercicio fué superior en el grupo S en relación a C. Se concluye que el padrón de respuestas al ejercicio agudo de los grupos C e S fué semejante. Con todo, la proteína de la dieta parece influir en los aspectos del metabolismo glicídico. Universidade Estadual Paulista Universidade Estadual Paulista

Em animais, os protocolos de Treinamento Físico Crônico (TF) aeróbio de nível moderado têm sido relacionados com a melhora da capacidade do sistema imunológico, como por exemplo o aumento dos leucócitos e a maior produção de citocinas e de oxido nítrico. Durante o envelhecimento, ocorre uma desregulação do sistema imunológico, conhecido como Imunossenescência, a qual contribui para o aumento da suscetibilidade a infecções, câncer e autoimunidade, e redução da resposta vacinal. Assim, o presente estudo verificou os resultados do TF sobre o sistema imunológico, avaliando a capacidade fagocítica dos macrófagos peritoneais oriundos de animais jovens e idosos. MATERIAL E MÉTODOS: Foram utilizados ratos da linhagem Wistar com 60 dias (Jovens) e com 14 meses de idade (Idosos), divididos em quatro grupos: Jovens Sedentários (JS) e Treinados (JT), e Idosos Sedentários (IS) e Treinados (IT). O protocolo de TF foi realizado através do exercício de nível por meio de natação por 45 minutos, três vezes na semana, por oito semanas consecutivas. Após, os macrófagos peritoneais foram desafiados em vitro, durante 30 e 120 minutos, com Escherichia Coli (E. coli) ou Candida albicans (C. albicans), previamente corados com FITC. Células com microrganismos internalizados foram quantificadas por meio de microscopia de fluorescência. RESULTADOS: Após o protocolo de EF, o percentual de macrófagos peritoneais com microrganismos internalizados, obtidos a partir dos ratos jovens ou idosos, foi maior (p < 0,05) em relação aos sedentários. Estes achados foram verificados tanto após desafio com bactérias E. coli quanto com fungos C. albicans, e independente do período de desafio. Os valores obtidos em 120 minutos foram superiores que aqueles correspondentes aos 30 minutos de desafio. Após o EF, os valores percentuais de macrófagos com microrganismos internalizados foram maiores entre os idosos que aqueles observados entre os jovens, independente do período de desafio (p < 0,05). Estas diferenças etárias também ocorreram entre os animais sedentários. CONCLUSÕES: O exercício físico aeróbio em nível moderado foi capaz de alterar a função fagocítica dos macrófagos. A maior internalização de microrganismos por parte dos macrófagos oriundos dos idosos, em relação aos jovens, pode refletir um estado prévio de ativação celular, em função do aumento da atividade inflamatória basal observado em idosos (inflammaging). In animals, the aerobic physical training (PT) of moderate level have been related with the improvement of the immunologic system capacity, like the increase of leukocytes and a higher production of cytokines and nitric oxide. While ageing, there is a deregulation of the immunologic system, known as Immunosenescence, which contributes to the increasing of the susceptibility to infections, cancer and autoimmunity, and the vaccine response. Thus, the present study examined the results of PF on the immune system, evaluating the phagocytic capacity of peritoneal macrophages derived from young and old animals. Material and Methods: Young (60-day old) and old (14-month old) Wistar mice were divided in four different groups: Sedentary Youngsters (SY) and Trained Youngsters (TY), Sedentary Elderly (SE) and Trained Elderly (TE). The physical training was based in an moderate aerobic PE protocol through swimming sessions of 45 minutes each, three times a week, for eight consecutive weeks. After that, the peritoneal macrophages were challenged in vitro, during 30 to 120 minutes, with Escherichia Coli (E.coli) or Candida albicans (C.albicans), previously dyed with FITC. Internalized microorganism cells were quantified through fluorescence microscopy. Results:After the PE protocol, the percentage of peritoneal macrophage with internalized microorganisms, from young and old mice, was higher (p
