Resumo
A insatisfação com a imagem corporal gera uma busca por melhoria através da prática de exercícios físicos, alimentação saudável e uso de suplementos alimentares. Um dos suplementos comumente utilizados é o cromo, que está relacionado ao metabolismo da glicose. A suplementação de picolinato de cromo (CrPic₃) pode influenciar o comportamento alimentar, o controle do apetite e vem sendo associada a promoção de massa magra e redução da gordura corporal. Recentes evidências sugerem que o exercício físico e a suplementação de CrPic₃ podem influenciar no controle de apetite. O objetivo deste estudo foi o de avaliar o efeito da associação da suplementação aguda de CrPic₃ e do sprint intervalado de alta intensidade (SIT) no controle de apetite e saciedade em humanos. O estudo foi do tipo duplo cego, randomizado, contrabalanceado e crossover. Para isso, sete indivíduos (30 ± 3,4 anos; 75 ± 12,4 kg; 1,69 ± 0,09 metros; 26,3 ± 2,15 kg/m²) foram submetidos a quatro experimentos, separados por sete dias: 1- CrPic₃-SIT (8 sprints de 15 seg + descanso de 2 min), 2- CrPic₃-REP (controle sem exercício), 3- PLA-SIT e 4- PLA-REP. A suplementação consistiu em duas doses de 500 µg de CrPic₃ ou placebo (amido resistente). A percepção subjetiva de apetite (PSA) foi avaliada por meio de uma escala visual analógica (VAS) em quatro momentos: 1) pré almoço, 2) pré exercício, 3) pós exercício e 4) pré jantar. A ingestão de nutrientes foi analisada por meio do registro no diário alimentar (24h) para quantificação calórica e padrão alimentar. O teste de análise de variância (ANOVA) de medidas repetidas foi utilizado para analisar possíveis diferenças entre as condições e momentos na percepção do apetite. Não houve diferenças significativas na PSA nos parâmetros de Fome, Saboroso e Salgado. No entanto, no experimento CrPic₃-SIT houve um aumento significativo no parâmetro Gorduroso. A PSA aumentou significativamente no parâmetro de Satisfação no experimento CrPic₃-SIT comparado aos outros experimentos. Assim como mostrou aumento significativo no experimento PLA-REP no parâmetro Doce. A diminuição mais significativa da ingestão calórica foi observada no experimento CrPic₃-REP. Embora o número relativamente pequeno da amostra, a suplementação de CrPic₃, quando combinada ou não ao SIT, apresentou resultados promissores no controle de apetite e saciedade. Contudo, existem aspectos como gênero, composição corporal, intensidade do exercício e posologia ideal que não foram elucidados.
Dissatisfaction with body image generates a search for improvement through physical exercises, healthy eating and the use of dietary supplements. Chromium is one of the most used because of its relation to the glucose metabolism. Chromium picolinate (CrPic₃) supplementation can influence eating behavior, appetite control and has been associated with promoting lean mass and reducing body fat. Recent evidence suggests that physical exercise and CrPic₃ supplementation can influence appetite control. The aim of this study was to evaluate the effect of the association of acute CrPic₃ supplementation and sprint interval training (SIT) on appetite and satiety control in humans. The study was double-blind, randomized, counterbalanced and crossover. For this, seven individuals (30 ± 3.4 years; 75 ± 12.4 kg; 1.69 ± 0.09 meters; 26.3 ± 2.15 kg/m²) were assigned to four experiments, separated by seven days: 1- CrPic₃-SIT (8 sprints of 15 sec + 2 min rest), 2- CrPic₃-REP (control without exercise), 3- PLA-SIT and 4- PLA-REP. Supplementation consisted of two doses of 500 µg CrPic₃ or placebo (resistant starch). The subjective perception of appetite (PSA) was assessed using a visual analogue scale (VAS) in four moments: 1) pre-lunch, 2) pre-exercise, 3) post-exercise and 4) pre-dinner. Nutrient intake was analyzed by recording in a food diary (24h) for caloric quantification and dietary patterns. The analysis of variance test (ANOVA) for repeated measures was used to analyze possible differences between conditions and moments in the perception of appetite. There were no significant differences in PSA in Hunger, Tasty and Salty parameters. However, in the CrPic₃-SIT experiment there was a significant increase in the Fatty parameter. The PSA significantly increased in the satisfaction parameter in the CrPic₃-SIT experiment in relation to the other experiments. Just as it showed a significant increase in the PLA-REP experiment in the Sweety parameter. The most significant decrease in caloric intake was observed in the CrPic₃-REP experiment. Despite the relatively small sample size, CrPic₃ supplementation, when combined or not with SIT, showed promising results in controlling appetite and satiety. However, there are aspects such as gender, body composition, exercise intensity and ideal dosage that have not been elucidated.
