Intervention model description: The study recruited the archery players in school teams among junior high, senior high schools, and colleges.
Primary purpose: TREATMENT

Brief summary: In our hypothesis, auricular acupoint stimulation might improve the attention and heart rate variability in archery athletes. The meridian activities regarding the attention and action in Chinese medicine systems might be influenced.

Detailed description: During the execution of archery, attention is the key of performance in elite players, especially in the initial period.

Auricular acupoint stimulation is one of the therapeutic methods of traditional Chinese medicine. It is widely applied in various diseases. Researches had concluded the use of auricular acupoint stimulation on amplifying the anesthesia effect, weight reduction and the cessation of substance abuse. This study aimed to investigate the immediate effect of non-invasive auricular acupoint stimulation on the performance and the meridian activities of archery athletes.

The investigators will collect the meridian activities and balance index with Ryodoraku device, the continuous heart rate record and the scores of the two sections as the performance. The participants will rate their attention and fatigue levels through filling the self-reported questionnaires.
