The present study determined the changes in appetite and appetite-regulating gut 
hormones during and following bouts of both rope skipping exercise 
(weight-bearing) and bicycle ergometer exercise (non-weight-bearing). After a 
12-h fast, 15 young men (mean ± SD, age 24.4 ± 1.7 yrs, maximal oxygen uptake 
47.0 ± 6.5 mL/kg/min) participated in three 160 min trials: (1) rope skipping 
exercise (295 ± 40 kcal, 3 sets × 10 min with 5-min interval, then rested for 
120 min); (2) bicycle ergometer exercise (288 ± 36 kcal, 3 sets × 10 min with 
5-min interval, then rested for 120 min); (3) control (rested for 160 min). 
Ratings of perceived hunger and acylated ghrelin were suppressed and total 
peptide YY (PYY) were increased during and immediately after exercise in both 
exercise trials, but glucagon liked peptide-1 was not changed. Furthermore, 
suppressed hunger during rope skipping exercise was greater than that during 
bicycle ergometer exercise, but there were no differences in acylated ghrelin 
and total PYY. These results indicate that weight-bearing exercise has a greater 
exercise-induced appetite suppressive effect compared with non-weight-bearing 
exercise, and both forms of exercise lowered acylated ghrelin and increased 
total PYY, but the changes did not differ significantly between exercise modes.
