چکیده انگلیسی
This study investigated the effects of continuous moderate-intensity exercise (MIE) and high-intensity interval exercise (HIIE) in combination with short exposure to hypoxia on appetite and plasma concentrations of acylated ghrelin, peptide YY (PYY), and glucagon-like peptide-1 (GLP-1). Twelve healthy males completed four, 2.6âh trials in a random order: (1) MIE-normoxia, (2) MIE-hypoxia, (3) HIIE-normoxia, and (4) HIIE-hypoxia. Exercise took place in an environmental chamber. During MIE, participants ran for 50âmin at 70% of altitude-specific maximal oxygen uptake (VËO2max) and during HIIE performed 6âÃâ3âmin running at 90% VËO2max interspersed with 6âÃâ3âmin active recovery at 50% VËO2max with a 7âmin warm-up and cool-down at 70% VËO2max (50âmin total). In hypoxic trials, exercise was performed at a simulated altitude of 2980âm (14.5% O2). Exercise was completed after a standardised breakfast. A second meal standardised to 30% of participants' daily energy requirements was provided 45âmin after exercise. Appetite was suppressed more in hypoxia than normoxia during exercise, post-exercise, and for the full 2.6âh trial period (linear mixed modelling, pâ<0.05). Plasma acylated ghrelin concentrations were lower in hypoxia than normoxia post-exercise and for the full 2.6âh trial period (pâ<0.05). PYY concentrations were higher in HIIE than MIE under hypoxic conditions during exercise (pâ=â0.042). No differences in GLP-1 were observed between conditions (pâ>â0.05). These findings demonstrate that short exposure to hypoxia causes suppressions in appetite and plasma acylated ghrelin concentrations. Furthermore, appetite responses to exercise do not appear to be influenced by exercise modality.
