“…Also, Willis et al [37], have shown that aerobic training and combined aerobic/ resistance training have reduced body weight significantly in obese adults compared to the baseline. Furthermore, Khammassi et al [38], have shown that a 12-week HIIT program, without dietary intervention, has induced a significant change in body weight compared to the baseline in healthy obese subjects. The clinical relevance of weight loss in NAFLD patients has been reported by earlier studies.…”

Background: Insufficient research exists on the effectiveness of exercise therapy in nonalcoholic fatty liver disease (NAFLD), particularly regarding the health-related quality of life (HRQoL) outcome. Therefore, this study aimed to assess the effects of high-intensity interval training (HIIT) compared to moderate-intensity combined resistance and aerobic training (RT/AT) on HRQoL in NAFLD patients. Material and methods: Twenty-three middle-aged obese women with NAFLD were enrolled in 3-month exercise interventions of either HIIT (n1 = 12, 46.3 ± 5 years, 40.5 ± 4.1 kg / m 2) or moderate-intensity combined RT/AT (n2 = 11, 45.6 ± 4.4 years, 43.5 ± 5.4 kg / m 2). Secondary hepatic steatosis, liver cirrhosis, or virus C hepatitis were excluded. HIIT was prescribed as 4 sets x 4 min at 80-85 % HRmax with 3 min active recovery. Combined RT/AT was prescribed as 10 min low to moderate cycling exercises followed by 8 resistance exercises at 50-75 % 1-RM. The outcomes were HRQoL, as assessed by the Chronic Liver Disease Questionnaire (CLDQ), and the percentage of body weight change (% ∆BW). Results: CLDQ domains were significantly improved in both HIIT & RT/AT groups compared to baselines; the emotional function & worry domains and the total CLDQ score were significantly higher in the HIIT group (p< 0.05)compared to the other group. Body weight was reduced by 13 % & 8 % in HIIT and combined RT/AT groups, respectively, with a significant difference in the % ∆ BW between the two groups in favor of HIIT. Conclusions: Both HIIT and moderate-intensity combined RT/AT could be suggested to improve the HRQoL and reduce body weight in middle-aged obese women with NAFLD, however, HIIT could be superior to the combined RT/AT in improving overall HRQoL, especially the emotional aspects, and reducing body weight.

“…Vários estudos tem mostrado que os exercícios aeróbicos, com intensidades entre 60% a 85% do VO 2máx. e frequência semanal de 3 a 5 vezes por semana, tem aumentado as concentrações séricas do HDL-c 15,17,33 . Nossos resultados são semelhantes a literatura, pois o grupo GSO aumentou o HDL-c ao final de 12 semanas de experimento (Tabela 3).…”

“…Os estudos tem mostrado que diferentes programas de exercícios físicos podem alterar a composição corporal e melhorar o perfil lipídico 15,[16][17][18] . No entanto, quando se associa os exercícios físicos com estratégias dietéticas, como a suplementação com óleo de coco, encontramos investigações com modelos animais 1,[19][20][21] e somente um estudo realizado com seres humanos 10 .…”

O objetivo deste estudo foi avaliar a suplementação de óleo de coco associado com um programa de exercícios físicos sobre a composição corporal e perfil lipídico em mulheres eutróficas normolipidicas. Participaram da pesquisa 20 mulheres que foram aleatoriamente divididas em 2 grupos, grupo exercício suplementado com 13 mL/dia de óleo de coco (GCO; n=10) e grupo exercício não suplementado com óleo de coco (GSO; n=10). Foram avaliados no início e ao final de 12 semanas de intervenção medidas perimétricas de adiposidade central, gordura (%), massa gorda, massa magra, níveis séricos de colesterol total, LDL-c, HDL-c e triglicérides. Para as comparações intragrupos e entre os grupos foi utilizado o teste T para amostras dependentes e independentes, com nível de significância de p<0,05. Os resultados mostraram que 12 semanas de intervenção modificou a adiposidade central do grupo GCO, diminuindo 2,6% a circunferência da cintura comparado ao grupo GSO (p<0,05). A gordura (%), massa gorda e massa magra não se modificaram após 12 semanas de intervenção nos grupos GCO e GSO (p<0,05). Na comparação do perfil lipídico entre os grupos, o grupo GCO diminui 3% o LDL-c enquanto que o grupo GSO aumentou 13,7% o colesterol total e 14,2% o LDL-c (p<0,05). Em conclusão, o óleo de coco associado com um programa de exercício físico aeróbico não modifica a composição corporal e atenua as alterações no perfil lipídico em mulheres eutróficas normolipidicas.

“…This suggests that HIIT which is designed on the basis of the specific sport techniques may be considered as a meaningful and important strategy for weight management in athletes. Most studies which are questioning the effect of HIIT programs on body composition have been conducted on overweight or obese individuals (19)(20)(21)(22)(23). Generally, it has been shown that shortterm HIIT elicit modest improvements in body fat levels in overweight and obese adults (19).…”

Background. High-Intensity Interval Training (HIIT) may affect Acylated Ghrelin (AG) through changes in body composition. Objectives. The present study was designed to investigate and compare the effects of two different orders of wrestling-based HIIT on AG levels and body composition in highly trained wrestlers. Methods. Forty-two male wrestlers (aged 16-21 years) were randomly assigned to one of three groups: HIIT23 (2 sets of 3 min wrestling techniques; by 80-90% HRmax); HIIT32 (3 sets of 2 min wrestling techniques; by 90-100% HRmax); and a control group that performed routine wrestling exercises. HIIT protocol consisted of eight techniques which were performed three days/week for eight weeks. Body composition and total plasma AG were measured 48 h before and after the protocol. Results. Body fat percentage (p<0.01) and weight (p<0.05) were significantly decreased in the HIIT groups from preto post-test. There was also a significant decrease in body fat percentage of both HIIT groups compared to the control group (p=0.002). Although a significant increase in post-test AG was observed in all the groups, AG levels in HIIT groups were approximately twofold higher than control group (p<0.01). Conclusion. It seems that eight weeks of wrestling-based HIIT can cause to significant decreases in body fat percentage and weight which is related to increase in total levels of plasma AG in highly trained wrestlers.
