| Summary: | 碩士 === 國立臺灣師範大學 === 體育學系 === 100 === Background: Brain derived neurotrophic factor (BDNF) is effective in enhancing cognition, learning, and energy metabolism. Enriched environment can increase BDNF concentration. Acute exercise can not only increase BDNF concentration but also enhance cognitive function. Purpose: This study aims to investigate and compare the effects of acute open skill badminton and acute closed skill running on increasing BDNF concentration and cognitive function. Method: The present recruited 23 healthy subjects (age: 22.78±2.54), who were respectively given acute 60%HRR badminton and running for 30 minutes by counterbalanced order. The subjects were examined on both BDNF concentration and cognitive function before and after the acute exercise. Results: The results show that both acute badminton and acute running significantly increased BDNF concentration, while the badminton is significantly more effective in improving BDNF concentration than the running (badminton vs. running: 4.29±2.92 vs. 2.21±4.14 ng/mL). Both badminton and running can reduce the reaction time of congruent and incongruent Flanker test (pre-exercise vs. post-exercise: 382.41±44.47 vs. 368.24±40.66 ms); however, there is no significant difference between the two types of exercise. In addition, the enhancement of BDNF concentration after acute exercise is not significantly correlate with the improvement in cognitive function after acute exercise (p>.05). Conclusion: This study suggests that exercise combined with enriched environment is effective in enhancing BDNF concentration; however, different types of acute exercise are not a factor in the enhancement of cognitive function.
