The present study investigated how different training frequencies during menstrual phases affect muscle hypertrophy and strength. Fourteen eumenorrheic women performed 3 sets of arm curls (8-15 repetitions) until failure for 12 weeks. Depending on the cycle phase, each subject trained separately after either a 3- or 1-d·wk protocol follicular phase (FP-T) luteal (LP-T). Cross-sectional area (CSA), 1 repetition maximum, maximum voluntary contraction significantly increased 6.2 ± 4.4, 36.4...
Acute land-based high-intensity exercise has been shown to alter food reward. However, it remains unclear regarding the acute effect of different intensities on Therefore, we examined response reward high- and low-intensity treadmill in healthy young men. Twelve men (aged 22.8 ± 2.0 years, mean standard deviation) completed three, half-day laboratory-based trials (i.e., exercise, control), a random order. In trials, participants ran for 60 min (from 09:30 10:30) at speed eliciting 70 %...
Acute moderate- to high-intensity exercise, primarily aerobic has been reported decrease food reward in brain regions via the hedonic pathways and reduce preference for high-energy or high-fat foods. However, studies examining responses acute exercise have limited measuring only after less frequently before exercise. Therefore, changes response remain unclear. This study investigated effect of running on healthy young men. Fourteen men (mean ± standard deviation, age; 23 2 years, body mass...
Although ample evidence supports the notion that an acute bout of endurance exercise performed at or greater than 70% maximum oxygen uptake suppresses appetite partly through changes in appetite-regulating hormones, no study has directly compared influence between phases menstrual cycle women. This effects on orexigenic hormone (acylated ghrelin) and anorexigenic hormones (peptide YY cholecystokinin) early follicular phase (FP) mid luteal (LP) physically active Ten healthy women (age, 20.6 ±...

Evaluation concentration by 13 C-magnetic resonance spectroscopy measurement estradiol, progesterone,...
Abstract Although thorough chewing lowers postprandial glucose concentrations, research on the effectiveness of vegetables in different forms metabolism remains limited. This study examined effects consumed solid versus puree metabolism. Nineteen healthy young men completed two 180-min trials separate days a random order: trial involved consumption shredded cabbage with and non-chewing pureed without chewing. Energy jelly was immediately after or cabbage. Blood samples were collected at 0,...
Butyrylcholinesterase (BChE), a liver-derived enzyme that hydrolyzes acylated ghrelin to des-acylated ghrelin, may trigger potential mechanism responsible for the acute exercise-induced suppression of ghrelin. However, studies examining effects an bout high-intensity exercise on BChE and have yielded inconsistent findings. This study aimed examine intensity BChE, concentrations in humans.Fifteen young men (aged 22.7 ± 1.8 years, mean standard deviation) completed three, half-day...
In women, fat oxidation during exercise changes with the menstrual cycle. This study aimed to investigate effect of green tea extract (GTE) ingestion on depending cycle phase. Ten women regular cycles participated in this randomized, double-blind, crossover study. GTE or placebo was administered cycle’s follicular phase (FP) and luteal (LP). Participants cycled for 30 min at 50% maximal workload, a respiratory gas analysis performed. Serum estradiol, progesterone, free fatty acid, plasma...
Ample evidence supports the notion that an acute bout of aerobic exercise and meal consumption reduces acylated ghrelin concentration. However, mechanisms by which this exercise- meal-induced suppression occurs in humans is unknown. This study aimed to examine concentration butyrylcholinesterase (BChE), enzyme responsible for hydrolysing other appetite-related hormones response a single running standardised young, healthy men. Thirty-three men (aged 23 ± 2 years, mean standard deviation)...
Abstract Female athletes who endure intense training are at risk of developing the 'female athlete triad,' making energy intake management crucial. However, fluctuations in estradiol and progesterone levels throughout menstrual cycle present a challenge maintaining consistent intake. This study aimed to uncover underlying factors associated with appetite regulation linked phases exercise using proteomic approach. Five female engaged 60 min bicycle exercise, followed by 90 rest, during both...
This study aimed to investigate the effect of menstrual cycle on serum carnitine and endurance performance healthy women. Fifteen eumenorrheic women underwent ergometer exercise at 60% maximal oxygen uptake (V̇ O2max) for 45 min, followed by an intensity that was increased 80% V̇ O 2max until exhaustion, during two phases, including early follicular phase (FP) midluteal (LP). The blood levels estradiol, progesterone, total carnitine, free acylcarnitine were assessed. Compared with FP, LP had...
Normal-weight obesity is defined as having high body fat but a normal mass index (BMI). This study examined whether there are differences in habitual physical activity and diet between individuals with normal-weight obese or non-obesity. included 143 males aged 65–75 years, they were classified into the following three groups according to BMI visceral area (VFA): group (n = 27 (BMI: ≥25 kg/m2 VFA: ≥100 cm2)), 35 <25 cm2)) non-obese 81 VFA < 100 cm2)). Lowered high-density lipoprotein...
Low-volume high-intensity interval training (HIIT) for weight loss has become prevalent in recent years, with increased excess post-exercise oxygen consumption (EPOC) as the mechanism. However, influence of menstrual cycle on EPOC and fat oxidation following low-volume HIIT is unclear. This study aimed to investigate effect increase after HIIT.Twelve eumenorrheic women participated during their early follicular luteal phases. On each experimental day, they performed comprising fifteen...
Testosterone replacement therapy (TRT) in transgender men (TM) results side effects such as elevated triglycerides and increased arterial stiffness. Exercise may be useful to ameliorate effects, but no studies have examined the of acute aerobic exercise TM.
