The purpose of this study was to investigate the acute and training effects of resistance exercise (RE) on serum lipid profile with different levels of cholesterol intake. Thirty‐seven elderly men (M, N=15) and women (F, N=22) were randomly assigned to a high‐cholesterol, medium‐cholesterol or low‐cholesterol supplementation group and performed a RE training program for 12 weeks. Blood samples were obtained immediately before, after (acute) and 48‐hour after RE (prolonged). There were no significant differences on lipid profile between supplementation groups. Dietary cholesterol availability may alter RE induced cholesterol metabolism. Before and after training, HDL‐C, LDL‐C, TC and TG showed acute increases after RE and returned to normal 48 hours later, except for TG, which was decreased 48 hours after the last training section. Men showed greater acute RE changes than women for TC and TG before training, and HDL‐C, LDL‐C and TC after training. In conclusion, serum lipids were acutely increased by RE, TG use may be enhanced by RE training, and there may be sex‐specific differences in some of these effects.Training Effect Acute effect before training Prolong ed effect before training Acute effect after training Prolong ed effect after trainingHDL‐C↑7.6% ↑9.2%
