| Περίληψη: | This study examined how resistance exercise (RE) volume, a potential key factor in appetite regulation, influences subjective appetite, gut appetite hormones, and energy intake. Eighteen males (aged 21–27 years) completed failure RE (FRE; three sets of failure reps at 70% (at 1 RM), non-FRE (NFRE; 3 × 7 reps at 70% 1 RM), and control (CON) trials. Appetite and acyl-ghrelin, peptide YY, lactate, and glucose were measured pre- and postexercise 0–90 min. Ad libitum meal was provided after exercise. Participants recorded energy intake for the day before, the day of, and the day after each session. The incremental area under the curve (iAUC) for acyl-ghrelin (AG) in the FRE and NFRE were significantly lower than in the CON (p <.001). Peptide YY iAUC and glucose iAUC in the FRE were significantly higher than in the CON (p <.001; p =.003). There was a dose–response for lactate iAUC (FRE > NFRE > CON; p <.001). Appetite iAUC was significantly lower in the FRE than in the CON (p =.012). There were no significant differences in postexercise ad libitum meal and self-reported free-living energy intake between the three sessions (p =.246, p =.226). Acyl-ghrelin was negatively correlated with lactate and positively correlated with overall appetite in both RE sessions. Lactate was negatively correlated with overall appetite in both RE sessions. Moderate-intensity RE with moderate volume-induced temporary appetite suppression, whereas FRE led to prolonged suppression and greater appetite-related hormonal responses, yet neither affected energy intake in young males. This study examined how different types of resistance exercise—commonly known as weight training—affect appetite, hunger-related hormones, and food intake. While aerobic exercise, such as running, is known to temporarily reduce appetite, less is understood about how resistance exercise influences hunger and eating behavior. Gaining this understanding could help people use strength training more effectively for weight management and healthy eating. The findings showed that moderate-intensity resistance exercise lowered levels of the hunger hormone compared with rest. Training to failure—continuing repetitions until no more could be completed—produced a stronger decrease in the hunger hormone ghrelin, along with greater increases in the satiety hormone peptideYY and blood lactate levels, than the nonfailure or control sessions. Participants also reported lower overall appetite after the failure exercise. However, despite reduced hunger signals, participants did not consume less food immediately after exercise or during the following day. Interestingly, higher lactate levels were linked to lower appetite and lower ghrelin concentrations, suggesting that the temporary buildup of lactate during intense resistance exercise may help suppress hunger. The more demanding the workout—particularly those performed to failure—the stronger these hormonal and appetite-related responses appeared to be. In summary, moderate-intensity resistance exercise can temporarily reduce appetite, and training to failure may strengthen and prolong this effect through changes in hunger-related hormones. However, these hormonal shifts did not lead to a measurable decrease in food intake among young men. These results suggest that while resistance training, especially to failure, can momentarily suppress appetite, it may not automatically reduce calorie consumption. Such insights can help fitness professionals and individuals design well-balanced training programs that promote both muscle development and healthy eating behaviors. [ABSTRACT FROM AUTHOR] |
