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.
