Appetite and gut hormone responses to moderate-intensity continuous exercise versus high-intensity interval exercise, in normoxic and hypoxic conditions

Abstract

26This study investigated the effects of continuous moderate-intensity exercise (MIE) and high-27 intensity interval exercise (HIIE) in combination with short exposure to hypoxia on appetite and 28 plasma concentrations of acylated ghrelin, peptide YY (PYY), and glucagon-like peptide-1 (GLP-1). 29Twelve healthy males completed four, 2.6 h trials in a random order: 1) MIE-normoxia, 2) MIE-30 hypoxia, 3) HIIE-normoxia, and 4) HIIE-hypoxia. Exercise took place in an environmental chamber. 31During MIE, participants ran for 50 min at 70% of altitude-specific maximal oxygen uptake (

Very Low Volume Sprint Interval Exercise Suppresses Subjective Appetite, Lowers Acylated Ghrelin, and Elevates GLP-1 in Overweight Individuals: A Pilot Study

“…Existing literature regarding the effect of exercise on the plasma GLP-1 concentration is limited. Martins et al [5] witnessed a significant increase in GLP-1 after intermittent cycling exercise at 65% estimated maximal heart rate (3 × 17 min with 3 min recovery), in healthy, normal-weight individuals, as well as after moderate-intensity continuous and high-intensity intermittent exercise in overweight and obese individuals [25]. In both cases, the increase was modest and transient, unlike the sustained increase observed in the present study.…”

“…A previous investigation has provided some evidence that an attenuation of the GLP-1 response to a glucose load in overweight, prediabetic, and diabetic individuals, compared with those with normal glucose tolerance, is more pronounced in females [41]. However, recent studies would indicate no sex differences in acute appetite and appetite-associated hormone responses to exercise in healthy-weight individuals [25,42,43]. …”

“…Appetite responses to HIE may be mediated by anorexigenic changes in circulating concentrations of the hunger hormone acylated ghrelin [22]. Contention remains regarding responses in the satiety peptide glucagon-like peptide 1 (GLP-1); non-significant, modest suppressions in GLP-1 have been accompanied by appetite suppression [25], while more profound suppressions have been seen in the absence of changes in appetite [26]. …”

Efeito agudo do exercício realizado em diferentes intensidades sobre a fome, hormônios relacionados ao apetite e ingestão alimentar em homens e mulheres

“…O efeito da intensidade do exercício na ingestão alimentar tem sido alvo de diversos estudos publicados recentemente (ALKATANI et al, 2014;BAILEY et al, 2015;DEIGHTON et al, 2013a;2013b, MARTINS et al, 2015SIM et al, 2014). BAILEY et al, 2015;DEIGHTON et al, 2013b, MARTINS et al, 2015SIM et al, 2014 HEYDARI et al, 2012;TRAPP et al, 2008).…”

Além disso, quando comparado a um programa com exercício de intensidade moderada, o treinamento em alta intensidade resultou em maiores impactos na redução da massa gorda (TRAPP et al, 2008).…”
