(Sport Sciences for Health, 2017-06) Fayh, Ana Paula Trussardi; Matos, Victor Araújo Ferreira; Souza, Daniel Costa de; Browne, Rodrigo Alberto Vieira; Santos, Victor Oliveira Albuquerque dos; Costa, Eduardo Caldas
Purpose: To compare the acute effects of high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) on appetite perception in overweight/obese males. Methods: Ten overweight/obese participants were submitted to two experimental sessions with 7 day intervals in a randomized order: (1) HIIE: 10 × 60 s at ~90% of maximal heart rate (HRmax) interspersed by 60 s of passive recovery; (2) MICE: 20 min at ~65% of HRmax. Standardized breakfast was offered before the exercise sessions. Hunger, satiety, fullness, and prospective food consumption perception were assessed pre-exercise, immediately post-exercise, and 40 min post-exercise. Results: No change in hunger, satiety, and prospective food consumption post-exercise was observed in both exercise sessions (p > 0.05). Fullness increased immediately post-exercise following HIIE (p = 0.022, r = −0.38), but it was not different from the MICE and was not sustained after 40 min post-exercise (p > 0.05). Conclusion: HIIE and MICE did not modify appetite (i.e., hunger, satiety, and prospective food consumption perception) until 40 min post-exercise in overweight/obese males, despite a transient increase in fullness observed immediately after the HIIE
Acute effects of high-intensity interval and moderate-intensity continuous exercise on GLP-1, appetite and energy intake in obese men: a crossover trial
(Nutrients, 2018-07) Fayh, Ana Paula Trussardi; Matos, Victor Araújo Ferreira; Souza, Daniel Costa de; Santos, Victor Oliveira Albuquerque dos; Medeiros, Ítalo Freire; Browne, Rodrigo Alberto Vieira; Nascimento, Paulo Ricardo Porfírio do; Marinho, Cristiane da Silva Ramos; Serquiz, Alexandre Coelho; Costa, Eduardo Caldas
This study investigated the effect of high-intensity interval (HIIE) and moderate-intensity continuous exercise (MICE) on glucagon-like peptide 1 (GLP-1), appetite and energy intake (EI) in obese men. In a randomized crossover trial, 12 participants (28.4 ± 2.6 years, 35.5 ± 4.5 kg/m2 , 39.8 ± 2.2% body fat) performed: (I) Control (CON, no exercise); (II) MICE (20 min, 70% of maximal heart rate) and (III) HIIE (10 × 1 min at 90% of maximal heart rate with 1 min recovery). GLP-1 and appetite were assessed at: (I) PRE: pre-exercise; (II) POST: immediately post-exercise; (III) POST-1 h: 1 h post-exercise. EI was assessed after an ad libitum meal offered 1 h post-exercise and over 24 h. There was a significant time × condition interaction for GLP-1 (p = 0.035). Higher GLP-1 levels in MICE vs. CON (p = 0.024) and a trend for HIIE vs. CON (p = 0.069) POST-1h was found. Hunger was reduced immediately post-HIIE compared to CON (p < 0.01), but was not sustained POST-1 h (p > 0.05). EI did not differ between the sessions 1 h post-exercise or over 24H (p > 0.05). In summary, although MICE increased GLP-1 levels POST-1h and HIIE induced a transient reduction in hunger, both exercise protocols did not impact EI in obese men

INTRODUÇÃO: Existem evidências na literatura que pessoas obesas submetidas a sessões de treinamento físico intenso de alto volume têm uma tendência a diminuir seu nível de atividade física (AF) e aumentar seu comportamento sedentário até 6 dias após as intervenções. Entretanto, poucos estudos relatam sobre o efeito do exercício intervalado de alta intensidade (EIAI) de baixo volume e exercício contínuo de moderada intensidade (ECMI) sobre o nível de atividade física e comportamento sedentário em adultos obesos. OBJETIVO: Analisar os efeitos de uma sessão de EIAI de baixo volume e ECMI sobre o tempo de prática de atividade física e comportamento sedentário em homens com obesidade. MÉTODOS: Participaram do estudo 14 homens adultos (25 a 35 anos) obesos (IMC ≥ 30 kg/m2 < 39,9 kg/m²) e fisicamente inativos (< 150 min/semana de atividade física moderada-vigorosa). Através de um ensaio clínico controlado e randomizado com delineamento cruzado, os voluntários realizaram duas sessões de exercício (EIAI e ECMI) e uma sessão controle (sem exercício), com intervalado de uma semana entre as sessões. O EIAI foi composto por 10 estímulos a 60 segundos com 90% da velocidade pico (Vpico) atingida no teste incremental e recuperação ativa de 60 segundos com 30% da Vpico. O ECMI foi realizado com uma intensidade correspondente a aproximadamente 70% da FCmáx calculada a partir do teste incremental na esteira. Ambas as sessões tiveram 20 minutos de duração. Após as sessões de exercício e controle, foi inserido o acelerômetro no quadril dos voluntários, posicionado ao lado direito. Os voluntários foram orientados a utilizar o acelerômetro por sete dias consecutivos. A ANOVA two-way (condições vs. tempo) com medidas repetidas para o segundo fator foi utilizada para analisar possíveis diferenças no nível de atividade física e comportamento sedentário ao longo de sete dias. RESULTADOS: não houve interação condição vs. tempo significativa no número de counts [F(12, 156) = 0,977, p = 0,473, η2 parcial = 0,07; EIAI: 217,4 ± 29,5; ECMI: 203,4 ± 40,3; controle: 203 ± 31,6], breaks [F(12, 940) = 0,556, p = 0,874, η2 parcial = 0,041; EIAI: 20,4 ± 2,4; ECMI: 21,2 ± 2,8; controle: 21,6 ± 2,9] e bouts [F(12, 816) = 0,425, p = 0,952, η2 parcial = 0,032; EIAI: 20,5 ± 2,2; ECMI: 20,5 ± 3,1; controle: 21,7 ± 2,8], tempo gasto em comportamento sedentário [F(12, 156) = 1,404, p = 0,169, η2 parcial = 0,097]; EIAI: 750 ± 109 min; ECMI: 773,1 ± 119,9 min; controle: 814,7 ± 149,2 min], atividade física leve [F(12,156) = 0,647, p = 0,80, η2 parcial = 0,047]; EIAI: 27,5 ± 27,3 min; ECMI: 288 ± 27 min; controle: 284,1 ± 25 min], moderada [F(12, 156) = 0,821, p = 0,629, η2 parcial = 0,059]; EIAI: 19,7 ± 3 min; ECMI: 18,4 ± 5,5 min; controle: 15,3 ± 2,3 min] e vigorosa [F(12, 156) = 1,692, p = 0,073, η2 parcial = 0,115]; EIAI: 0,7 ± 0,8 min; ECMI: 0,4 ± 0,4 min; controle: 0,3 ± 0,4 min] ao longo de sete dias. CONCLUSÃO: uma sessão de EIAI de baixo volume e ECMI não alterou o nível de atividade física e comportamento sedentário em homens com obesidade.

(Sport Sciences for Health, 2018-02) Fayh, Ana Paula Trussardi; Matos, Victor Araújo Ferreira; Souza, Daniel Costa de; Santos, Victor Oliveira Albuquerque dos; Marinho, Cristiane da Silva Ramos; Serquiz, Alexandre Coelho; Friedman, Rogerio; Costa, Eduardo Caldas
Background: Few have analyzed the effects of different intensities of acute physical exercise on biochemical parameters of cardiovascular disease. Aim: To examine the acute effects of high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) on biochemical cardiovascular markers in obese male adults. Materials and methods: Twelve sedentary obese male subjects (28.4 ± 2.6 years old, BMI 35.5 ± 4.5 kg/m2, 39.8 ± 2.2% body fat) took part in this randomized, cross-over clinical trial. Three experimental sessions, at 7-day intervals, in random order, were carried out: (1) HIIE: 10 × 60 s at ~ 90% of maximal peak velocity, interspersed by 60 s of active recovery, (2) MICE: 20 min at ~ 70% of maximum heart rate, and (3) control session. A standardized breakfast was offered before the exercise sessions. Biochemical markers of cardiovascular risk (glycemia, total cholesterol and fractions, triglycerides, hepatic enzymes and nitrogen scores) were assessed pre-exercise, immediately post-exercise, and 60 min post-exercise. Results: In general, no significant interaction was observed, with the exception of creatinine, that had a statistically significant two-way interaction between time and condition, F(4,40) = 5.053, p < 0.05. There was a statistically significant two-way effect in time, F(2,22) = 5.906, p < 0.05 for AST, and a statistically significant two-way effect in treatment, F(2,22) = 13.477, p < 0.05 for glucose. Conclusion: In this context, HIIE seems to be a safe alternative to MICE for the prevention and management of obesity, as well as the disorders observed in this population
Effects of high-intensity interval and moderate-intensity continuous exercise on inflammatory, leptin, iga, and lipid peroxidation responses in obese males
(Frontiers in Physiology, 2018-05) Fayh, Ana Paula Trussardi; Souza, Daniel Costa de; Matos, Victor Araújo Ferreira; Santos, Victor Oliveira Albuquerque dos; Medeiros, Ítalo Freire; Marinho, Cristiane da Silva Ramos; Dorneles, Gilson Pires; Peres, Alessandra; Muller, Carlos Henrique de Lemos; Krause, Maurício; Nascimento, Paulo Ricardo Porfírio do; Costa, Eduardo Caldas
Purpose: To compare the effects of a single high-intensity interval exercise session (HIIE) with a moderate-intensity continuous exercise session (MICE) on the inflammatory profile, IgA levels, and lipid peroxidation in sedentary obese males. Methods: Ten sedentary obese men (age 28.5 ± 2.7 years; BMI 35.9 ± 4.9 kg/m2; body fat 40.6 ± 2.0%) performed three experimental sessions, on separate days with 1 week wash-out period between interventions, according to a randomized order: (1) HIIE: 10 × 60 s at 90% of the HRmax alternated by 60 s of active recovery; (2) MICE: 20 min at 70% of the HRmax; (3) Rest—control. Blood and saliva samples were collected before, immediately after and 60 min after the end of each session in order to analyse serum levels of cytokines, IgA, and lipoperoxidation markers. Results: Leptin levels decreased immediately after HIIE (P = 0.033) and was different from the MICE (P = 0.025). IFN-γ levels were reduced immediately after (P = 0.032) and 60 min after HIIE (P = 0.003) compared to baseline, and it also increased IL-4 levels immediately after exercise (P = 0.007) compared to resting values. MICE promoted an increase in IFN-γ levels immediately after exercise (P = 0.025) and 60 min after exercise (P = 0.004) in relation to baseline. Both exercise conditions increased IL-6 levels up to 60 min after exercise (P < 0.05). The IFN-γ/IL-4 ratio decreased immediately after (P = 0.002) and 60 min after HIIE (P = 0.005) in relation to pre-exercise. No changes were found for IgA-S and TBARS for any of the conditions. Conclusion: A single HIIE session is able to decrease IFN-γ/IL-4 ratio, indicating an anti-inflammatory response, without alterations in the function of the mucosal immune system and lipoperoxidation. On the other hand, a brief session of MICE induced changes in the pattern of cytokines associated with increased cellular immune function
Effects of high-intensity interval and moderate-intensity continuous exercise on physical activity and sedentary behavior levels in inactive obese males: a crossover trial
(Journal of Sports Science and Medicine, 2019-08) Fayh, Ana Paula Trussardi; Santos, Victor Oliveira Albuquerque dos; Browne, Rodrigo Alberto Vieira; Souza, Daniel Costa de; Matos, Victor Araújo Ferreira; Macêdo, Geovani Araújo Dantas; Farias Junior, Luiz Fernando; Farias Junior, José Cazuza; Costa, Eduardo Caldas
A total of 17 participants (30.2 ± 4.8 years; 35.4 ± 4 kg/m2; 38.2 ± 3.6 % body fat) were enrolled in this randomized crossover trial to analyze the effects of a single session of high-intensity interval (HIIE) and moderate-intensity continuous exercise (MICE) on the physical activity and sedentary behavior levels in inactive obese males. The participants performed two exercise sessions and one control session (no exercise): i) low-volume HIIE (10 x 60 s at 90% of maximal aerobic velocity [MAV] interspaced by 60 s at 30% of MAV); ii) MICE (20 min at 70% of maximum heart rate); and iii) control (25 min in a seated position). After all sessions, the physical activity and sedentary behavior levels were monitored by accelerometer over seven consecutive days. No differences in the physical activity (activity counts, and time spent at light, moderate, and vigorous intensities) and sedentary behavior (time spent at sedentary behavior, breaks, and bouts) levels were found among the sessions (HIIE, MICE and control) (p > 0.05). In summary, a single session of HIIE and MICE does not change the physical activity and sedentary behavior levels in inactive obese males. Therefore, low-volume of both high- and moderate-intensity exercise should be considered for inactive obese males given that it does not reduce the physical activity level or increase the time spent at sedentary behavior
A single session of low-volume highintensity interval and moderateintensity continuous exercise elicits a transient reduction in ghrelin levels, but not in post-exercise energy intake in obese men
(Archives of Endocrinology and Metabolism, 2021) Fayh, Ana Paula Trussardi; Matos, Victor Araújo Ferreira; Souza, Daniel Costa de; Browne, Rodrigo Alberto Vieira; Santos, Victor Oliveira Albuquerque dos; Medeiros, Ítalo Freire; Nascimento, Paulo Ricardo Porfírio do; Costa, Eduardo Caldas
Objective: This study investigated the acute effects of high-intensity interval (HIIE) and moderateintensity continuous (MICE) exercise on ghrelin levels in obese men. Subjects and methods: Atotal of 10 obese men (age 27.6 ± 1.8 years, body mass index 35.4 ± 4.5 kg/m², body fat 39.9 ± 2.1%)performed two exercise sessions in a randomized order: HIIE (10 x 1 min intervals at 90% of themaximal heart rate [HRmax] interspersed by 1 min of active recovery) and MICE (20 min at 70% ofthe HRmax). Ghrelin levels were assessed pre-, post- and 1h post-exercise, and energy intake wasassessed 1h post-exercise through an ad libitum meal. Results: HIIE and MICE showed a trend todecrease ghrelin levels immediately post-exercise (-14.1 ± 21.6% and -9.6 ± 23.8%, respectively, p= 0.07) and decreased 1h post-exercise (-12.7 ± 31.8% and -13.8 ± 21.7%, respectively, p < 0.05). Nochanges were observed for post-exercise energy intake (p > 0.05). There was a positive correlationbetween the change in ghrelin levels and post-exercise energy intake only for HIIE (r = 0.63, p =0.05). Conclusion: In summary, a single session of HIIE and MICE elicits a reduction on ghrelin levelswithout changing post-exercise energy intake in obese men
