摘要

Background and Purpose: This study aims to investigate the effects of agility training on executive function, walking performance and brain activation while dual task walking in healthy adults. Methods: Eligible participants were randomly assigned to resistance + aerobic training group (RAeT) or agility training group (AT). Participants in RAeT (n = 6) received 15-minute lower extremity workout and a 25-minute aerobic training conducted in moderate intensity (60-75% predicted maximal heart rate). Participants in AT (n = 6) performed agility exercise program consisting of technical drills, pattern running and reactive agility training. The intervention was conducted with nine-sessions group intervention (3-5 persons) in three weeks, 50 minutes per session (5-minute warmup, 40-minute main training, 5-minute cool-down). Participants underwent pre-, post-intervention and one-month follow-up assessment. Outcome measures include the task performance and brain activation while performing 3 domains of executive function test (N-back test, Stroop test, Wisconsin card sort test), and single and dual task walking. The targeted areas of cerebral activation including bilateral prefrontal cortex, supplementary motor area and premotor cortex which monitored by functional near-infrared spectroscopy. Results: Intra-group comparison showed AT group reduced incongruent response time significantly in Stroop test between pre-test and follow-up (p < 0.05). In addition, the inhibitory control time decreased between pre and post-test (p < 0.05) comparing to RAeT group. Both groups showed a significant time effect in answer speed of arithmetic task while dual task walking between the three time points. Regarding to the brain activation, the activation level in the most of channels showed a trend to decrease activation while post-test and follow-up comparing to pre-test, though these observations didn't reach the significant level. Conclusions: There is a positive trend on performance of executive function, dual task walking and brain plasticity after 9-session agility training in young adults. Clinical Relevance: Agility training may be economical and effective to improving cognitive and motor function in healthy adults.
