【Objective】The purpose of this study was to investigate the acute responses of adiponectin and leptin to resistance exercise in healthy elderly men. 【Methods】Eight healthy men (age, 25.5±3.3 yrs) participated in this study. They performed two trials. Trial 1 was an exercise session consisting of 5 resistance exercises at high-intensity (75% one-repetition maximum : 1 RM) with three sets of 10 repetitions. Trial 2 was a control trial at rest for the same time as trial 1. Blood samples were taken to assess adiponectin, leptin, and metabolism related substances (glucose and lipids).【Results】Leptin significantly decreased 24 h after the resistance exercise but did not change in trial 2. Blood insulin and lactate concentrations significantly increased immediately (0 min) and 30 min after the exercise. However, adiponectin, glucose and lipids were not affected. 【Conclusion】Adiponectin was not affected by resistance exercise, whereas leptin decreased 24 h after the exercise. This suggests that leptin may have quite a delayed response to high-intensity resistance exercise.
