Immediate Effect of Non-invasive Auricular Acupoint Stimulation for the Performance and the Meridian Activities of Archery Athletes

Not Applicable

Completed

• Conditions: Sport Injury; Stress, Physiological
• Interventions: Other: Auricular acupoints stimulation

• Registration Number: NCT04637607
• Lead Sponsor: Chang Gung Memorial Hospital

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.

Arm && Interventions

Group	Intervention	Description
Ear-Acupressure Group	Auricular acupoints stimulation	The subjects will receive true auricular acupoints stimulation with the attachment of Vaccaria seeds during the first round of play. After finishing the first round, the subjects will receive sham auricular acupoints stimulation.

Primary Outcome Measures

Name	Time	Method
The change of meridian activities	Baseline, one hour, two hours	The meridian activities and balance index were measured and calculated with Ryodoraku device. (Meridian Energy Analysis Device, MEAD, medpex, Taiwan) The activity will be shown by numbers which were calculated by the skin electric resistance. The higher the number is, the higher meridian activity is presented.
The change of Checklist Individual Strength, CIS	Baseline, one hour, two hours	The self-reported attention and fatigue questionnaire which is composed with 30 items. Each item ranks from zero to five. Higher scores indicated higher distraction and fatigue levels.
The change of Visual Display Terminals visual syndrome, VDTs fatigue scale	Baseline, one hour, two hours	The self-reported attention and fatigue questionnaire which focus at visual syndrome. VDTs fatigue scale is been applied and standarized by Japanese Ministry of Health, Labor and Welfare survey results, 2004. VDTs fatigue scale is composed with 13 items. Each item ranks from zero to five. Higher scores indicated higher distraction and fatigue levels.
The change of heart rate variability	Two and half hours, keep recording during the whole process	Analyzed by continuous heart rate recording with heart rate monitor (Garmin, the U.S.)

Secondary Outcome Measures

Name	Time	Method
The change of motion stabilization	Two and half hours, keep recording during the whole process	Recorded and analyzed by the WIMU PRO (RealTrack Systems, Almería, Spain) The bluetooth data will be collected and analyzed to show the motion characteristics.
