Previous issue date: 2017-07-10 / Introdu??o: O exerc?cio f?sico ? considerado uma estrat?gia fundamental no tratamento da obesidade por promover aumento no d?ficit cal?rico. Evid?ncias recentes sugerem que o exerc?cio de alta intensidade pode induzir altera??es fisiol?gicas que diminuem o apetite, contribuindo para redu??o da ingest?o cal?rica, fen?meno conhecido como anorexia induzida pelo exerc?cio (AIE). Objetivo: comparar o efeito agudo do exerc?cio intervalado de alta intensidade (EIAI) e exerc?cio cont?nuo de intensidade moderada (ECMI) sobre o consumo energ?tico e percep??o do apetite em homens com obesidade. M?todos: A pesquisa caracterizou-se como um ensaio cl?nico randomizado com delineamento cruzado. Quinze volunt?rios (31,0 ? 6,1 anos, 31,0 ? 6,0 kg/m?, 40,1 ? 2,2% de gordura corporal) foram submetidos a tr?s sess?es experimentais, separadas por sete dias: I) EIAI (10 x 1 min a 90% da frequ?ncia card?aca m?xima [FCm?x] + 1 min recupera??o ativa), II) ECMI (20 min a 70% da FCm?x) e III) Controle (sem exerc?cio). Uma refei??o padronizada foi oferecida 60 min antes de cada sess?o. A percep??o subjetiva do apetite (fome, saciedade, plenitude e perspectiva de consumo alimentar) foi avaliada por meio de uma escala visual anal?gica (EVA) em tr?s momentos: 1) pr?-sess?o, 2) p?s-sess?o e 3) uma hora ap?s sess?o. O consumo alimentar ad libitum foi analisado uma hora ap?s as sess?es experimentais e controle, por meio de registro pesado e o consumo alimentar ao longo do dia da sess?o (24 h) foi avaliado por meio de um registro alimentar estimado. A ANOVA two-way com medidas repetidas foi utilizada para analisar poss?veis diferen?as entre as condi??es e momentos na percep??o do apetite e uma ANOVA de medidas repetidas para analisar as diferen?as entre as condi??es no consumo alimentar ad libitum e 24 h. Resultados: N?o houve diferen?as significativas na percep??o de fome [F(1,3, 17,5)=0,00, p=0,972], saciedade [F(1,3, 17,5)=0,00, p=0,972], plenitude [F(2, 28)=0,13, p=0,876] e perspectiva de consumo [F(2, 28)=0,76, p=0,476] entre as condi??es, bem como n?o foram identificadas diferen?as significativas no consumo energ?tico na refei??o ad libitum: CON (674,5 ? 252,1), ECMI (666,7? 213,8) e EIAI (689,6? 263,8kcal) [F (2, 28)=0,13, p=0,877] e ao longo do dia da sess?o: CON (2857,6 ? 867,2), ECMI (2608,5? 595) e EIAI (2556,1? 489,5kcal) [F (2, 28) = 1,54, p=0,233]. Conclus?o: Uma sess?o de EIAI e ECMI n?o modificou o apetite e o consumo energ?tico ap?s 60 min e ao longo do dia em homens com obesidade. / Introduction: Physical exercise is considered a fundamental strategy in the treatment of obesity by promoting increase in the caloric deficit. Recent evidence suggests that high-intensity exercise can induce physiological changes that suppress appetite, decreasing caloric intake, a phenomenon known as exercise-induced anorexia (EIA). Objective: compare the acute effect of high intensity interval exercise (HIIE) and continuous moderate intensity exercise (ECM) on energy intake and appetite perception in obese men. Methods: The study was characterized as a randomized clinical trial in cross-over design. Fifteen volunteers (31.0 ? 6.1 years, 31.0 ? 6.0 kg/ m?, 40.1 ? 2.2% body fat) underwent three experimental sessions, seven days apart: I) HIIE ( 10x 1 min at 90% of maximal heart rate [HRmax] + 1 min active recovery), II) ECM (20min to 70% of HRmax) and III) Control (without exercise). A standardized meal was offered 60 min before each session. Appetite perception (hunger, satiety, fullness and perspective food consumption) were evaluated through a visual analogue scale (VAS) in three moments: 1) Pre-session, 2) Post-session and 3) one hour after session. Energy intake was assessed one hour after session with an ad libitum meal and the consumption throughout the day (24hrs) was analyzed with a estimated food record. ANOVA Two-way with repeated measures was used to analyze the differences between conditions and moments on appetite perception and ANOVA with repeated measures to assess the differences between conditions on energy intake in ad libitum and 24hrs. Results: There were no significant differences on hunger [F (1.3, 17.5) = 0.00, p = 0.972], satiety [F (1.3, 17.5) = 0.00, p = 0.972], fullness [F (2, 28) = 0.13, p = 0.876] and prospective food consumption [F (2, 28) = 0.76, p = 0.476] between conditions. As well as no significant differences on energy intake were observed during ad libitum meal: CON (674,5 ? 252,1), ECM (666,7? 213,8) e HIIE (689,6? 263,8kcal) [F (2, 28) = 0.13, p = 0.877] and throughout the day CON (2857,6 ? 867,2), ECM (2608,5? 595) e HIIE (2556,1? 489,5kcal) [F (2, 28) = 1.54, p = 0.233].Conclusion: A single session of HIIE and ECM did not modified appetite and energy intake 60 min after and during the day following exercise in obese man.
