Introdução: A acumulação de gordura na região abdominal acarreta um maior risco para a saúde. Objetivo(s):
Analisar o efeito de um protocolo de uma sessão de exercício físico aeróbio associada à eletrolipólise no tecido
adiposo da região abdominal nos valores do consumo e proporção dos substratos energéticos. É ainda objetivo
avaliar as diferenças no consumo e proporção dos substratos energéticos, com o mesmo protocolo, no sexo
feminino e no sexo masculino. Métodos: 38 participantes foram distribuídos aleatoriamente por dois grupos, o
grupo experimental (9 feminino e 9 masculino) e o grupo placebo (11 feminino e 9 masculino). Ambos os grupos
foram avaliados através das medidas antropométricas e foram sujeitos aos dois protocolos do estudo, o de
microcorrente com aplicação 2 frequências (25 e 10Hz), 20 minutos cada, e o de exercício aeróbio a 45-55%
frequência cardíaca de reserva. Contudo, no grupo placebo a microcorrente foi realizada sem intensidade. Para
obtenção dos valores do consumo e proporção dos substratos foi utilizado o K4b2 durante o exercício físico.
Resultados: Não se verificaram diferenças significativas nas quantidades de ácidos gordos, glucose e no
quociente respiratório entre os grupos (ρ> 0,05). No entanto, parece haver uma tendência para um maior
consumo de ácidos gordos após a aplicação da microcorrente durante o exercício físico. Conclusão: Os
resultados deste estudo indicam que uma sessão de eletrolipólise associada ao exercício físico aeróbio não parece
ser suficiente para influenciar a quantidade do consumo e a proporção dos substratos energéticos numa amostra
de indivíduos jovens de ambos os sexos.
Background: The accumulation of fat in the abdominal region entails a greater risk to health. Aim(s): Analyse the effect of one protocol in one session of aerobic exercise associated to electrolipolysis in the adipose tissue of the abdominal region in the expenditure and proportion of energy substrates. It’s also an objective to examine the differences in the expenditure and proportion of substrates, with the same protocol, in women and men. Methods: 38 participants had been distributed randomly by two groups, experimental group (9 women and 9 men) and placebo group (11 women and 9 men). Both groups were evaluated through anthropometric measurements and they were subjected to the two protocols of the study, the microcurrent with two frequencies (25 and 10 Hz), 20 minutes each one, and the aerobic exercise at 45-55% of heart rate reserve. Though, in the placebo group the microcurrent was made without intensity. To obtain the values of expenditure and proportion of the energy substrates was used the K4b2 during exercise. Results: There were no significant differences in the quantity of fatty acids, glucose and in respiratory exchange ratio between groups (ρ> 0.05). However, there seems to be a trend towards a higher consumption of AG after the application of microcurrent during exercise. Conclusion: The results of this study indicate that one session of electrolipolysis associated with aerobic exercise seems to be insufficient to influence the consumption and the proportion of energy substrates in young individuals of both sexes.
