研究目的：比較優秀運動員與健康成人 8 週高強度間歇訓練前、中及後壓力賀爾蒙、肌肉損傷、發炎、免疫反應及有氧運動表現的變化差異，以及各項反應之間的關聯性。研究方法：招募優秀運動員與健康成人各 20 名，隨後進行 8 週的 HIIT 介入，並於介入前、第 1、4 及 9 週檢測壓力賀爾蒙、肌肉損傷、發炎反應指標。另外介入前、中及後檢測免疫功能與有氧能力運動指標。所得資料以混合設計二因子變異數分析檢定不同實驗處理與時間點的差異。再以皮爾森積差相關檢驗各變項間的相關性。隨後使用多元迴歸評估影響有氧能力運動表現的指標。預期結果：健康成人經8 週 HIIT 介入各變項反應皆大於運動員。健康成人與運動員的各項反應隨介入週數增加而上升，但健康成人各項反應指標變化幅度較大。另外，運動員與健康成人的有氧運動能力表現皆可能獲得提升。
Purpose: Present study aim to compare the differences of stress hormones, muscle injury, systemic inflammatory response, immune function, and aerobic performance for high-intensity interval training (HIIT) between athletes and healthy adults for 8 weeks. And further investigate the correlations between variables reactions. Method: A 8 weeks of HIIT intervention is conducted by 40 subjects for both elite athletes and healthy adults group. Stress hormones, muscle injury, systemic inflammatory response indicators are detected at pre-intervention, week 1, 4 and 9. In addition, immune function and aerobic exercise performance indicators will be tested at pre-, during and post-intervention. Data will be analyzed by mixed design two-way ANOVA to examine the differences between groups and test time points. The pearson's-correlation coefficient are used to find the relationship between variables. Then, multiple regression are used to assess the impact on athletic aerobic performance. Expected results: After 8 weeks of HIIT intervention, the responses of all variables of healthy adults will be greater than athletes. The responses of each variable in athletes and healthy adults will be elevated as intervention period increased. However, the magnitude of responses are greater in healthy adults when compare to athlete. On the other hand, both groups significantly improve the aerobic performance after intervention.
