ABSTRACT
ABSTRACT This study aimed to verify the effect of exercise recovery time on the affective responses during a circuit training in physical education classes. Forty-six apparently healthy young adolescents (twenty-one girls) (12.85 ± 0.94 years; 49.7 ± 8.93 kg; 1.59 ± 0.08 cm; 19.51 ± 3.28 kg/m2) participated in this study. Were submitted participants for two physical education classes, based on circuited model of the same intensity, but with different recovery times (2 min and 1 min). The study was carried out in two phases: baseline and intervention. Affect, Arousal, and Ratings of Perceived Exertion data were analyzed using paired t-tests, considering a significance level of p < 0.05. The class with longer rest time (2 min) provided greater affection (t(45) = 3.586; p < 0,001) and less perceived effort (t(45) = 2.295; p = 0,026). The intensity manipulation strategy was effective in providing different affective responses, in which classes perceived as more intense, resulting in the decline of affect.
RESUMO O objetivo do estudo foi verificar o efeito do tempo de recuperação do exercício nas respostas afetivas durante um treinamento em circuito nas aulas de educação física. Quarenta e seis jovens adolescentes aparentemente saudáveis (vinte e uma meninas), com (12.85 ± 0.94 anos; 49.7 ± 8.93 kg; 1.59 ± 0.08 cm; 19.51 ± 3.28 kg/m2), participaram do estudo. Os participantes foram submetidos a duas aulas de educação física escolar, baseados em modelo de circuitos de mesma intensidade, porém com tempos de recuperação diferentes (2 min e 1 min). O estudo foi realizado em duas fases: base e intervenção. Os dados de Afeto, Ativação e Percepção Subjetiva do Esforço, foram analisados através de testes t pareados, considerando um nível de significância de p < 0,05. A aula com maior tempo de descanso (2 min) proporcionou maior afeto (t(45) = 3.586; p < 0,001) e menor esforço percebido (t(45) = 2.295; p = 0,026). A estratégia de manipulação da intensidade foi efetiva para proporcionar respostas afetivas diferentes, em que a aula percebida como mais intensa resultou no declínio do afeto.

Abstract Background Resistance training is used in different exercise programs, with different objectives and different levels of physical fitness. Training-related variables, such as volume, rest time and intensity, can affect the response of blood pressure (BP), but studies on the effect of these variables on BP are still needed. Objective To evaluate the acute response of BP in trained individuals undergoing two different methods of resistance training. Methods The sample was divided into three groups: (1) the German volume training (GVT) (n= 15), which consisted of 10 series of 10 repetitions at 50% of 1-repetition maximum (RM) with intervals of 30 seconds; (2) the sarcoplasm stimulating training (SST) (n= 16), performed at 8 RM and 85% of 1-RM and interval of 10 seconds until failure, followed by removal of 20% of weight and repetition of the whole series (total of three sets), and the control group (CG) (n= 15) who underwent BP measurements only. The two-way repeated measures ANOVA was used for analysis of variations, and a p< 0.05 was considered statistically significant. Results In the within-group analysis, a significant lowering of systolic blood pressure (SBP) was found at 10 minutes (125.4±10.8 mmHg, p= 0.045) and 20 minutes (124.5±8.5 mmHg, p= 0.044) post-training compared with immediately after training. In the between-group comparison, higher SBP values were observed immediately after training in the SST group (142.1±28.2, p= 0.048) compared with the CG. Conclusion High-volume and high-intensity resistance training programs did not cause abnormal changes in blood pressure. (Int J Cardiovasc Sci. 2021; [online].ahead print, PP.0-0)

RESUMO Diversas intervenções têm sido relatadas na literatura com intuito de modular o comportamento da Variabilidade da Frequência Cardíaca (VFC) em idosos. Entretanto a maioria deles são focados em capacidades físicas condicionantes. Pouco se sabe sobre os efeitos que um treinamento coordenativo estruturado em circuitos pode promover na VFC de idosos. O objetivo do presente estudo foi investigar o efeito de 8 semanas de uma intervenção coordenativa sob aspectos autonômicos de idosos. 26 sujeitos foram divididos em dois grupos. Um grupo (N=13) com Abordagem Coordenativa em Circuito (GACC) e outro grupo (N=13) que realizou Caminhada Recreacional (GCR). Para a mensuração da VFC foi utilizado um cardiofrequencímentro. Para avaliação motora foi utilizado um Circuito Motor Modelo que consistiu em 8 exercícios de coordenação. Para avaliação da aptidão física funcional foi utilizada a bateria de Fullerton. Após 8 semanas de intervenção tanto as variáveis da VFC como as variáveis motoras não diferiram entre os grupos. Porém quando observado os momentos pré e pós intervenção foi encontrado, apenas no GCR um aumento na variável High Frequency, 5 minutos após Circuito Motor Modelo. Nossos resultados indicaram que oito semanas de uma intervenção coordenativa não foi suficiente para gerar alterações no comportamento da VFC dos idosos.
ABSTRACT Several studies were registered in the literature to modulate the Heart Rate Variability (HRV) in the elderly. However they are focused on the physical ability of conditioners. Little is known about the effects that structured coordinative training in circuits can promote in the HRV of the elderly. The objective of the present study was to investigate the effect of 8 weeks of a coordinative intervention under autonomic aspects of the elderly. 26 subjects were divided into two groups. One group (N = 13) with the Coordination Approach in Circuit (CACG) and the other group (N = 13) with the Recreational Walk (RWG). To measure HRV, a cardiofrequencimeter was used. Motor Circuit Model was used for the motor evaluation, which consisted of 8 coordinative exercises. For the evaluation of functional physical fitness, the Fullerton battery was used. After 8 weeks of intervention, both HRV variables and motor variables did not differ between groups. However, when the pre and post intervention moments were observed, only in the RWG was an increase in the variable High Frequency, 5 minutes after Motor Circuit Model. Our results indicated that eight weeks of a coordinative intervention was not sufficient to generate changes in the HRV behavior of the elderly.

The present study investigated the behavior of glycemia in subjects with type 2 diabetes (T2DM) during 36 sessions of a combined training program. Methods: This is a single arm clinical study with 20 patients with T2DM submitted to combined exercise training (strength and aerobic exercise). The sessions occurred on alternate days, 3x/week, lasting ~ 80 minutes, totaling ~ 240 minutes/week, for 12 weeks, over a total of 36 sessions. Capillary glycemia was measured before and 10 to 15 minutes after the end of each combined exercise session. Results: There was a significant reduction (p<0.05) in glycemia after application of the combined training program in 27 (75%) of the 36 sessions. Regarding the maintenance of this reduction after about 48 hours, no significant differences were identified (p>0.05). When investigating the cumulative effect of the 36 sessions of combined training program on capillary glycemia, no significant differences were observed (p>0.05). Conclusion: Glycemia exhibits a behavior of reduction immediately after concurrent strength and aerobic training programs in patients with T2DM. However, the immediate reduction of glycemia is not maintained until 48 hours, nor is there a cumulative effect of the 36 training sessions on baseline glycemia.(AU)

Estudo quase-experimental que teve como objetivo analisar o efeito de diferentes periodizações no treinamento concorrente sobre parâmetros imunológicos, metabólicos, ponderais e de qualidade de vida relacionada à saúde (QVRS) em mulheres com sobrepeso e/ou obesidade. Participaram do estudo 33 mulheres as quais foram separadas aleatoriamente em três grupos: grupo não periodizado (NP: N = 11), grupo periodização ondulatória (PO: N = 9) e o grupo periodização ondulatória flexível (POF: N = 13). O programa de treinamento teve duração de 12 semanas e as participantes foram avaliadas antes e ao término do programa. Os dados foram analisados por meio de estatística descritiva e análise de variância ANOVA. Os resultados mostraram que a média de idade entre os três grupos foi de 60,8 ± 6,6 anos, sendo observada a presença de doenças metabólicas em 26 participantes (78,8%), sendo que 19 participantes (57,6%) apresentavam hipertensão arterial, 15 participantes (45,5%) dislipidemia e 5 participantes (15,2%) diabetes mellitus, lembrando que elas poderiam apresentar até as 3 doenças concomitantemente. Quando comparados antes e após o treinamento, e também quando comparados os três grupos entre si (tempo 2), não foi observada diferença estatística nos parâmetros metabólicos: glicemia de jejum, colesterol total, lipoproteína de alta densidade (HDL), lipoproteína de baixa densidade (LDL), e triglicérides, assim como nos parâmetros ponderais: massa corporal, índice de massa corporal e circunferência da cintura. Em relação aos testes físicos, não foi observado aumento da força de membros superiores e inferiores quando as participantes foram comparadas antes e após o treinamento. No entanto, observou-se melhora significativa na resistência aeróbia após o treinamento, por meio do teste da caminhada de 6 minutos, nos grupos NP e PO. Já quando os grupos foram comparados entre si (tempo 2), observou-se melhora na força no teste de flexão de braço do grupo POF comparado ao NP, e melhora na resistência aeróbia no teste da caminhada de 6 minutos do grupo PO comparado ao NP. Na carga máxima dinâmica, quando comparados antes e após o treinamento, houve aumento de força nos grupos PO e POF no supino inclinado, no entanto, este aumento não foi observado no leg press. Já quando comparados os três grupos entre si (tempo 2), observou-se melhora da força dos membros inferiores no leg press do grupo PO comparado ao NP; e POF comparado ao NP. Quanto a QVRS, somente quando comparados os três grupos entre si após o período de treinamento é que foi observada melhora da capacidade funcional do grupo PO comparado ao NP. Em relação aos parâmetros imunológicos, quando comparados antes e após o treinamento, e também quando comparados os três grupos entre si (tempo 2), não foi observado diferença estatística nas concentrações de IL-6 e TNF-?. Conclui-se que o treinamento concorrente do grupo PO foi eficiente em melhorar a resistência aeróbia e o ganho de força dos membros superiores em participantes fisicamente ativas com sobrepeso e/ou obesidade na faixa etária dos 50 a 70 anos
This was a quasi-experiment study that aimed to analyze the effect of different periodization models on concurrent training over immunological, metabolic, weight parameters and healthrelated quality of life (HRQoL) in overweight and/or obese women. Thirty-three women were randomly assigned to three groups: non-periodized group (NP: n = 11), undulating periodization group (UP: n = 9) and flexible undulating periodization group (FUP: n = 13). The training program lasted 12 weeks and participants were assessed before and at the ending of the program. The data were analyzed by means of descriptive statistics and the ANOVA variance analysis. The results showed that the mean age of the three groups was 60,8 ± 6,6 years, and observed the presence of metabolic diseases in 26 participants (78,8%), of which, 19 participants (57,6%) had arterial hypertension, 15 participants (45,5%) dyslipidemia and 5 participants (15,2%) diabetes mellitus, reminding that they could present up to 3 diseases concomitantly. When compared before and after training, and when comparing the three groups with each other (time 2), there was no statistical difference in metabolic parameters: fasting glucose, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL) and triglycerides, as well as in the weight parameters: body mass, body mass index and waist circumference. Regarding physical tests, no increase in upper and lower limb strength was observed when participants were compared before and after training. However, a significant improvement in cardiorespiratory fitness was observed after training through the 6-minute walk test in the NP and UP groups. When the groups were compared with each other (time 2), there was an improvement in strength in the arm curl test of the group FUP compared to NP, and improvement in cardiorespiratory fitness in the 6-minute walk test of the group UP compared to NP. At the maximum dynamic strength, when compared before and after training, there was an increase in strength in the UP and FUP groups in the inclined bench press, however, this increase was not observed in the leg press. When the three groups were compared with each other (time 2), an improvement in the strength of the lower limbs was observed in the leg press of the groups UP compared to the NP; and FUP compared to NP. Regarding HRQoL, only when comparing the three groups with each other after the training period is that it was observed an improvement in physical function of the group UP compared to the NP. Related to the immunological parameters, when compared before and after training, and when comparing the three groups with each other (time 2), no statistical difference was observed in IL-6 and TNF-? concentrations. In conclusion, the concurrent training of the PO group was efficient in improving aerobic resistance and upper limb strength gain in physically active participants with overweight and/or obesity in the age group of 50 to 70 years

O estudo foi aprovado por Comitê de Ética em Pesquisa. Foram identificadas variáveis sociodemográficas e clínicas. As variáveis clínicas foram medidas antes, durante e após sessões de treinamento em um circuito multimodal. Para as análises descritivas, foram calculadas as frequências absolutas, porcentagens, medianas, médias e desvio padrão. Para a análise de confiabilidade intraobservador e de concordância, foram utilizados o Coeficiente de Correlação Intraclasse (CCI) e o teste de concordância Bland-Altman, usando o pacote estatístico SPSS® V24. Para a identificação da igualdade de médias no teste e no reteste foram utilizados os testes paramétricos t-pareado e One-way ANOVA medidas repetidas, para variáveis contínuas e com distribuição normal, tomadas nos momentos antes e depois. Para os casos onde as suposições de normalidade e/ou esfericidade não foram atendidas, foram utilizados os testes não paramétricos de Wilcoxon ou Friedman. A intensidade do limiar anaeróbio (ILAN) e a Frequência Cardíaca na Intensidade do Limiar Anaeróbio (FCILAN) foram identificadas a partir de três critérios. Participaram do estudo 20 idosos, na maioria mulheres, com idade entre 60 e 65 anos, de cor branca, convivendo com companheiro, com mais de 12 anos de escolaridade, aposentados. Ao testar a reprodutibilidade da ILAN em dois momentos distintos com o mesmo avaliador, observamos que a média dos escores obtidos no teste e reteste foi semelhante (>,05) indicando boa correlação entre os pares analisados (r = ,77 a ,91). Nossos resultados também mostraram alta confiabilidade em todos os critérios adotados para determinação do LAN (CCI=,86 a ,95), além de boa concordância das medidas teste e reteste para o LAN2 do 1° e 3° critérios por meio do método de análise Bland-Altman. Identificamos redução da pressão arterial na primeira hora após o treinamento em circuito, em comparação com os valores pré-intervenção, nos momentos teste e reteste. O principal achado de nosso estudo se deu pela confiabilidade e concordância entre as medidas teste-reteste para as variáveis estudadas, sugerindo adequação do circuito multimodal incremental na determinação do LA de idosos por meio da dosagem do Lactato Sanguíneo
Regular physical activity brings several benefits to elderly people, but it's necessary to identify a training prescription that can be performed in a safe and effective manner for this population. The Multimodal Training is an alternative to stimulate physical skills and abilities important to maintaining health and autonomy in aging. The purpose of this study, with quantitative approach and quasi-experimental delineation, was to measure the reliability of an incremental multimodal circuit in the determination of the anaerobic threshold (ANT) of elderly people through blood lactate dosage. The study was approved by the Ethics in Research Committee. Social demographic clinical variables were found. Clinical variables were measured before, during and after the training sessions in a multi-modal circuit. For descriptive analysis, absolute frequencies, percentages, medians, averages and standard deviation were calculated. For intra-observer reliability and agreement analysis, we used the Interclass Correlation Coefficient (ICC) and Bland-Altman agreement test, using statistical package, SPSS® V24. To the measures equality identification in the test and retest were used the t-paired parametrics and One-way ANOVA repeated measures, to continuous variables and with normal distribution, taken moments before and after. To the cases where normality and/or spherecity were not satisfied, we used Wilcoxon or Friedman non-parametric tests. The anaerobic threshold intensity (ATI) and the heart rate in the anaerobic threshold intensity (HRATI) were identified according to three criteria. Participated in the study 20 elderly people, mostly women, between the ages of 60 and 65 years old, white colored, living with a partner, with more than 12 years of schooling, retired. When testing the reproducibility of ATI in two different times with the same evaluator, we observed the measure of the obtained scores in the test and retest was similar to (>,05), indicating a good correlation between the analyzed pairs (r = ,77 a ,91). Our results also showed high reliability in all adopted criteria to determine ATI (CCI=,86 a ,95), in addition to the good agreement of the test and retest measures to the ATI2 of the first and third criteria through Bland-Altman analysis method. Was identified arterial pressure reduction in the first hour after the circuit training, compared with preintervention values, in the test and retest moments. The main discovery was given through reliability and agreement between measures test-retest to the studied variables, suggesting adjustment of the incremental multimodal circuit in the determination of the elderly people ATI through blood lactate dosage

Introdução: O efeito da ordem dos exercícios no Treinamento Circuito (TC) sobre variáveis hemodinâmicas é inconclusivo. Objetivo: Avaliar o efeito de diferentes ordens de execução nas respostas hemodinâmicas agudas no TC. Métodos: Onze homens foram recrutados. As sessões de treinamento foram compostas pela seguinte sequência: Sequência A: multiarticulares/monoarticulares; Sequência B: monoarticulares/multiarticulares, realizados a 60% de 1-RM com intervalo de um minuto. Ambos circuitos foram compostos por três passagens com oito estações. Os desfechos foram: pressão arterial sistólica (PAS), diastólica (PAD), frequência cardíaca (FC) e duplo produto (DP). Para comparações utilizou-se ANOVA two-way medidas repetidas considerando p<0.05. Resultados: Os valores da FC foram significativamente mais altos durante e após o exercício em comparação ao momento pré (p<0,001), aumento do DP (p< 0,001) e diminuição da PAS (p<0,001) após os treinos, independente da ordem dos exercícios. Conclusão: O método de TC é eficiente em promover o efeito hipotensor pós-exercício independente da ordem de execução.
Introduction: The effect of Circuit Training (CT) order's on hemodynamics variables is inconclusive. Objective: To evaluate the effect of different orders of execution in acute hemodynamic responses in the CT. Methods: Eleven men were recruited. Training sessions were composed by the following sequence: sequence A: multi-joint/single-joint; Sequence B: single-joint/multi-joint, performed at 60% of 1-MR with one minute interval. Both circuits were composed of three passes with eight stations. The outcomes were: systolic blood pressure (BPS), diastolic (DPS), heart rate (HR) and double product (DP). For comparisons was used twoway ANOVA repeated measures considering p<0.05. Results: HR values were significantly higher during and after exercise compared to baseline, increase of DP (p< 0,001) and decrease of BPS (p<0,001) after practice, regardless of the order of exercise execution. Conclusion: The CT method is efficient in promoting the hypotensive effect post-exercise regardless of the order of execution.

The aim of this study was to determine if rating of perceived exertion (RPE) could be used to monitor the internal load during compounded circuit training (CCT) sessions in women. Thirteen young adults women performed three sessions of CCT varying the intensity according to participants' maximum heart rate (50, 70 and 90%HRmax). Throughout the main part of CCT (35min), HR and RPE were measured. Both variables were significantly different among the exercise intensities. However, HR and RPE were not correlated. Probably because HR at the end of exercise was similar to the beginning at 90% and 70% of HRmaxintensities, and lower than the beginning instant at 50% of HRmaxintensity, whereas RPE increased from the beginning instant to the end of exercise for all intensities. Therefore, RPE is suitable to monitor the internal load during CCT sessions in women due to its possibility to detect the (in)tolerance to exercise, despite of the lack of correlation with HR.

BACKGROUND: Physical inactivity and reduced energy expenditure lead to increase in obesity among office workers. In this study, we investigated how 10 weeks of high intensity circuit training and working environment improvement can change body composition, physical strength and markers of metabolic syndrome. METHODS: A total of 83 employees at risk for metabolic syndrome participated in 10 weeks program of one-hour circuit training (30 minutes twice weekly) and workplace improvement program, which consisted of dynamic stretching twice daily for all weekdays. Body composition, anthropometry, blood test, muscle strength/endurance and cardiopulmonary function of participants were assessed at the baseline and after 10 weeks. RESULTS: At the end of 10 weeks, significant increases in levels of body composition, serum lipids, muscle strength and cardiopulmonary were observed in metabolic syndrome risk factor group. In body composition, significant improvements of body weight, body mass index, lean body mass, %body fat, visceral adipose tissue, waist and hip circumference and systolic blood pressure, diastolic blood pressure were observed in metabolic syndrome risk factor group. In lipids, hemoglobin A1c and high density lipoprotein were increased significantly in metabolic syndrome risk factor group. In muscle strength and endurance, significant increases were found. Also, there was a significant difference in cardiovascular function of maximal oxygen uptake and total running time among the groups. CONCLUSIONS: These intensive 10 weeks of high intensity circuit training and workplace improvement program were effective in improving body composition, muscle strength/improvement and cardiopulmonary function. Therefore, based on this study result, workplace improvement programs might be more developed and applied for high-risk employees to improve their metabolic syndrome.

OBJECTIVE: To explore the amount of practice and progression during task-oriented circuit training (TOCT) in chronic stroke survivors; to test the use of pedometers and observation-based measures in detecting step activity; to verify the possible correlation between step activity and locomotor function improvements. METHODS: Six community-dwelling chronic stroke survivors underwent 10 TOCT sessions (2 hours/each) over 2 weeks in which they were trained both on a treadmill and on six task-oriented workstations (W1–W6). During the sessions, they wore a piezoelectric pedometer and step activities were recorded. Outcome measures were as follows: % of activities during which pedometers worked properly; pedometer-based measures (total step counts, treadmill steps, workstation steps—total and W2,W3,W5,W6); observation-based measures (number of repetitions in task W1 and W4); walking speed changes measured by the 10-m walking test (10MWT) and walking endurance changes (6-minute walking test) after TOCT. RESULTS: During TOCT sessions (n=57), activities were recorded through pedometer-based measures in 4 out of the 6 patients. The total amount of step activity was 5,980.05±1,968.39 steps (54.29% in task-oriented workstations, 37.67% on treadmill, and 8.03% during breaks). Exercise progression was highlighted significantly by observational measures (W1, W4). A positive correlation was observed between increased gait speed and observational stair step repetitions progression (W1) (r=0.91, p=0.01) or pedometer-based tandem exercise step progression (W3) (r=0.98, p=0.01). CONCLUSION: TOCT can be considered a high-intensity, progressive intervention to restore locomotor function in chronic stroke survivors. Pedometer-based measures might help in quantifying TOCT's volume of practice; however, further investigations are required.
