緒論：探討下坡跑運動時穿著壓縮腿套對運動後誘發肌肉損傷及動脈硬化指標-踝臂脈波傳導速率 (brachial-ankle pulse wave velocity, baPWV)的影響。方法：12名無規律運動習慣之成年男性，採隨機方式於 運動中單腳穿著壓縮腿套（試驗腳），以另一腳為控制腳，接受一次70 %保留心跳率（70 %HRR)強度，坡度 為-10度之30分鐘原跑步機下坡跑運動，並於下坡跑運動前（前測）及下坡跑運動後24小時（後測）分別進 行依變項的檢測，檢測項目包含：肌酸激酶、baPWV、酸痛指數、主動關節活動度、肌肉腫脹圍、最大自主 等長收縮肌力及超音波股直肌肌肉厚度。結果：1、下坡跑運動後24小時之CK值（467.08 ± 229.64 U/L)顯 著高於前測（240.92 ± 189.67 U/L)(p< .05) ； 2、baPWV在試驗處理及時間因子的交互作用未達顯著，僅時間 因子顯示後測的baPWV (1110.71 ± 51.30 cm/s)顯著高於前測（1042.92 ± 38.17 cm/sj < .05) ； 3.酸痛指數、主 動關節活動度、肌肉腫脹圍、最大自主等長收縮肌力及超音波股直肌肌肉厚度等在試驗處理及時間因子亦無 交互作用存在，且試驗處理之主要效果亦未達顯著（P > .05)。結論：穿著壓縮腿套並無法減緩下坡跑運動所 引起的肌肉損傷，及隨後的延遲性肌肉酸痛與暫時性的baPWV上升之現象。

Introduction: To investigate the effects of downslope jogging, with compression leggings, on exercise-induced muscle injury and an arteriosclerosis marker, brachial-ankle pulse wave velocity (baPWV). Methods: Twelve adult men with no habit of regular exercise were randomized to wear a compression legging on one leg (test leg), while their other leg was designated as the control leg. These subjects underwent 30 minutes of downslope jogging exercise on a treadmill with 70% heart rate reserve (70% HRR) intensity and a gradient of -10°. Dependent variable tests were carried out prior to the simulation of downslope jogging (pre-test) and 24 hours after the simulation of downslope jogging (post-test). The test items included: creatine kinase (CK), baPWV, soreness index, active joint mobility, muscle swelling circumference, maximum autonomous isometric contraction muscle strength, and ultrasonic rectus muscle thickness. Results: a) The CK values at 24 hours after downslope (467.08 ± 229.64 U/L) jogging were significantly higher than those during the pre-test period (240.92 ± 189.67 U/L) (p〈0.05). b) The interaction effects of experimental treatment and time factor on baPWV did not reach a level of significance, with only the time factor showing the post-test baPWV (1110.71 ± 51.30 cm/s) as being significantly higher than the pre-test baPWV (1042.92 ± 38.17 cm/s; p < .05). c) No interaction effects between experimental treatment and time factors were found with respect to soreness index, active joint mobility, muscle swelling circumference, maximum autonomous isometric contraction muscle strength, and ultrasonic rectal muscle thickness. None of the major effects of the experimental treatment were significant (p >0.05). Conclusion: Wearing compression leggings did not decrease muscle damage caused by downslope jogging, nor did it reduce subsequent delayed-onset muscle soreness and temporary baPWV rise.
