Methods: Twenty-four male participants without a regular habit of exercising were enrolled in this study and were randomly allocated to either Experiment One: wearing compression garments during exercise or Experiment Two: wearing compression garments for 24 hours (24 h) after exercise. After administering pre-tests to all participants, they were required to carry out 30 minutes of downhill running (−10 degrees) at an intensity of 70% heart rate reserve (70% HRR), followed by post-tests at 24 h after exercise. The test items included: creatine kinase (CK), muscle soreness index, active range of motion (AROM), muscle swelling circumference, maximum voluntary isometric contraction (MVIC), 50% maximum voluntary isometric contraction-soreness index (50% MVIC-soreness index), thickness of the rectus femoris muscle, and baPWV. Results: Experiment 1: 1. Twenty-four hours after downhill running exercise, the CK values were significantly higher than those before exercise (p< 0.05) and there were no significant differences (p > 0.05) in 50% MVIC-soreness index between the experimental and control legs. 2. The interaction between soreness index, AROM, MSC, MVIC, rectus muscle thickness, and baPWV did not reach statistical significance and out of the main results, only the time factor reached statistical significance (p < 0.05). Experiment 2: 1. Twenty-four hours after downhill running exercise, the CK values were significantly higher than those before exercise (p <0.05) and there were no significant differences (p > 0.05) in 50% MVIC-soreness index between the experimental and control legs. 2. The interaction between soreness index, AROM, MSC, MVIC, and rectus muscle thickness before exercise, 24 hours after exercise (compression garments were wear but this did not include muscle swelling circumference, MVIC, and rectus muscle thickness), and 24.5 hours after exercise (compression garments not wear) did not reach statistical significance. Among the main effects, only the time factor reached statistical significance (p< 0.05). 3. baPWV interactions reached statistical significance. baPWV at 24 hours after exercise with compression garments on the experimental legs was significantly lower than that in control legs (p < 0 .05). Conclusion: Wearing lower-body compression garments during or after exercise could not alleviate the muscle damage induced by downhill running or the subsequent occurrence of delayed onset muscle soreness, but could reduce the risk of transient arterial stiffness.壓縮服飾運動傷害離心運動脈波傳導速率延遲性肌肉酸痛compression garmentssports injuryeccentric exercisepulse wave velocitydelayed onset muscle soreness
