“…O critério adotado para estabelecer o dispêndio energético proveniente do ECR também não é padronizado: alguns relatam o gasto calórico total da sessão, que inclui a mensuração do consumo de oxigênio durante o exercício somado ao EPOC (17)(18)(19)(20)(21)(22)(23)(24)(25) , outros apenas mensuram o EPOC (9,14,15,(26)(27)(28) ou nem isso, não considerando o período de recuperação pós-exercício para o cálculo do gasto calórico total da sessão (8,29) . Dentre os métodos de prescrição do treinamento, foram testadas as influências de trabalhos em circuito e em séries consecutivas (16,19,22) , manipulando-se o número de séries (23,24) , a intensidade (16,17,20,26,27) , o intervalo de recuperação entre séries e exercícios (17,19) , a velocidade da contração muscular (14,20,21) e a ordem dos exercícios (15) .…”

“…Além disso, associam-se ao componente lento ou ultralento do EPOC o aumento no metabolismo dos ácidos graxos, catecolanemia, cortisol e dano muscular, dentre outras variáveis (10,14) . Considerando a cinética do EPOC, 12 dos 17 estudos encontraram EPOC com duração menor ou igual a uma hora (15)(16)(17)(19)(20)(21)(22)(25)(26)(27)(28)30) e apenas cinco aferiram-no durante o mesmo período de tempo para o qual relataram sua duração total (16,17,19,25,28) . Ou seja, cerca de 1 / 3 das pesquisas apresentou a limitação metodológica de interromper a medida do EPOC antes que os seus valores retornassem à linha de base.…”

RESUMOO exercício contra-resistência (ECR) pode contribuir para o aumento da taxa metabólica de repouso (TMR). É consenso na literatura que o volume da sessão de ECR pode repercutir em maior gasto calórico e que, após o exercício, o consumo de oxigênio em excesso (EPOC) pode variar de acordo com a característica do programa de exercício. Contudo, ainda não é possível definir qual ou quais variáveis de prescrição têm maior impacto sobre o EPOC em sessões de ECR. O objetivo do estudo foi efetuar uma revisão sistemática sobre os estudos que se propuseram a investigar as relações entre o EPOC e variáveis de treinamento em ECR. Os 17 estudos selecionados foram agrupados por similaridade de tratamento (número de séries, intensidade, intervalos de recuperação, velocidade da contração muscular e ordem dos exercícios). Técnicas de estatística descritiva foram utilizadas na tentativa de estabelecer possíveis tendências nas relações dose-resposta. Posteriormente, os dados foram analisados de forma qualitativa. De todas as variáveis analisadas, o curto intervalo de recuperação e o modo de prescrição no formato em circuito foram aquelas com maior impacto provável sobre a magnitude do EPOC. Quanto às demais variáveis, limitações metodológicas não permitem estabelecer tendências, principalmente no tocante à duração do EPOC. Adicionalmente, constata-se a necessidade de padronização de aspectos importantes para a quantificação do EPOC, como o tempo de observação do após o exercício e a forma de aferição da TMR.Palavras-chave: EPOC, fisiologia do exercício, treinamento de força, aptidão física, saúde. ABSTRACTResistance training (RT) may influence resting metabolic rate (RMR) increase. There is a consensus that the volume of the RT session may produce higher caloric expenditure and that the excess post-exercise oxygen consumption (EPOC) may vary according to the characteristics of the exercise program. However, it is not possible yet to define which prescription variables have greater impact on the EPOC. The aim of the present study was to systematically review the studies that investigated the relationship between EPOC and training variables. A total of 17 studies were selected, being organized according to treatment similarity (number of sets, intensity, rest interval, speed of muscle contraction and exercise order). Descriptive statistical techniques were used to establish possible tendency in dose-response relationships. Subsequently, data were qualitatively analyzed. The available evidence suggested that a short rest interval and the circuit training prescription mode had the greatest impact on the EPOC magnitude. As for the other variables, it was not possible to establish any tendency due to methodological limitations, especially concerning EPOC duration. In addition, it seems to be necessary to standardize important aspects of the EPOC assessing, such as the period of observation after exercise and criteria for measuring RMR.

“…e EPOC effect is greatest soon aer the exercise is completed and decreases over time. Aerobic training is considered as the most effective exercise to increase energy expenditure (EE) and EPOC [1], but resistive training (RT) has been also shown to have a favorable impact [2][3][4][5][6][7]. It is accepted that during recovery the EPOC goes along with greater fat burn, which is a desirable effect to weight loss purposes [3,8].…”

Objectives. Resistance training may in�uence the resting metabolic rate (RMR), which is desirable in weight management programs. However, its impact on excess postexercise oxygen consumption (EPOC) is yet to be de�ned. e study evaluated the contribution of resistance training variables to EPOC. Design. Studies published until November 2011 were systematically reviewed. Methods. MEDLINE, LILACS, SCIELO, Science Citation Index, Scopus, SPORTDiscus, and CINAHL databases were consulted. e methodological quality of studies was assessed by the PEDro 10-point scale. A total of 155 participants (54% men) aged between 20 ± 2 and 34 ± 14 years were observed by 16 studies (quality scores ranged from 5 to 7), which were organized according to treatment similarity (number of sets, intensity, rest interval, speed of movement, and exercise order). Results. Training volume seemed to in�uence both EPOC magnitude and duration, whereas workload in�uenced mostly the magnitude. Short rest intervals (<60 s) increased the EPOC magnitude, but not the overall energy expenditure. Conclusion. Resistance training with high intensity and volume, performed with short rest intervals (as in circuit training), probably have greater impact on EPOC. Methodological procedures, particularly time of post-exercise observation and RMR assessment, should be standardized to an appropriate quanti�cation of the actual in�uence of resistance training on EPOC.

“…Ωστόσο, αν και η άσκηση μυϊκής ενδυνάμωσης με αντιστάσεις αποτελεί ένα αποτελεσματικό ερέθισμα με το οποίο προκαλείται αυξημένη λειτουργία του νευρικού και ενδοκρινικού συστήματος, στην οποία συμπεριλαμβάνεται και η αυξημένη έκκριση κατεχολαμινών (Goto, Ishii, Kizuka, & Takamatsu, 2005), δεν υπάρχει επάρκεια μελετών σχετικά με την επίδραση που ενδεχομένως να έχει στη λιπόλυση. Σε μελέτη του Ormsbee et al (2007), διερευνήθηκε η επίδραση της άσκησης με αντιστάσεις σε υγιείς άνδρες, με τη μέθοδο της μικροδιαπίδυσης. Από τα αποτελέσματα της μελέτης καθίσταται σαφές πως η άσκηση αντιστάσεων συμβάλλει στην αύξηση της (Stich et al, 2000).…”

Chatzinikolaou Athanasios: Lipids metabolism during resistance exercise (Under the supervision of Professor Taxildaris Kiriakos)Resistance exercise is recommended for the treatment of obesity and diabetes. Its effect on triacylglycerol lipase activity in adipose tissue is not known. The aim of the present study was to investigate the effect of resistance exercise (RE) on lipid metabolism in lean and obese humans. Nine lean and 8 obese healthy men performed a 30-min circuit RE protocol (3 cycles of 10 exercises at 70-75% maximal strength). At baseline, 5 minutes, end of 1st, 2nd and 3rd cycle we sampled adipose tissue for triacylglycerol lipase assay; and blood for norepinephrine, epinephrine, insulin, glucagon, cortisol, non-esterified fatty acid (NEFA), glycerol, glucose and lactate determination. Respiratory gases were monitored throughout exercise. The analysis of data indicated that relative energy expenditure was higher in the lean (2.9 ± 0.5 vs. 2.6 ± 0.8 kcal kg-1, P < 0.05). Respiratory exchange ratio during exercise was higher in the obese (0.98-1.03 vs. 0.92-0.97), suggesting lower fat oxidation.Triacylglycerol lipase activity increased 18-fold at 5 min in the lean and 16-fold at approximately 10 min in the obese; thereafter it declined without reaching baseline. The delay in lipolytic activation in the obese was reflected in the NEFA and glycerol concentrations. Plasma catecholamines increased throughout exercise with no differences between groups. Plasma insulin increased in the obese but did not change in the lean.These findings show that RE upregulated adipose tissue lipolysis and enhanced energy expenditure in lean and obese men. Lipolytic activation in the obese displayed a delay which may be due to the hyperinsulinemic response and may be accountable for the lower fat utilization.
