摘要: | 背景:高血壓是現今社會中對全民健康具有極大威脅的問題之一,不良的血壓數值代表著健康的警訊,也是諸多心血管疾病的致病風險。過去的研究表明,不同型態的運動方式皆可達到降低血壓的目的,其中等長收縮訓練具有最大程度降低收縮壓的潛力。目的:本研究以降低前高血壓患者的血壓為目標,比較等長收縮訓練 (主動收縮) 與缺血預處理 (被動收縮) 對其效果的影響。方法:本研究招募20位成年男性(收縮壓:132.9 ± 4.4 mmHg;舒張壓:79.1 ± 5.5 mmHg),隨機分配至控制組 (CON)、缺血預處理組 (IPC)、等長收縮運動組 (ISO)、混合組 (MIX),進行連續五天的實驗介入,並觀察在介入後次最大運動測試中的血壓、心率、心率變異性變化。資料分析使用混合設計二因子變異數分析 (Two-way ANOVA, mixed design) ,以及成對樣本T檢定 (paired sample t test),顯著水準設為p < .05。結果:經過連續五日介入後的收縮壓變化,缺血預處理組 (pre vs. post, 133.3 ± 4.9 mmHg vs. 125.2 ± 3.6 mmHg, p = .00, Cohen's d = 2.7)、等長收縮運動組 (pre vs. post, 132.5 mmHg ± 4.4 vs. 127.4 ± 4.1 mmHg, p = .00, Cohen's d = 2.1)、混合組 (pre vs. post, 132.5 ± 4.4 mmHg vs. 126.3 ± 3.1 mmHg, p = .00, Cohen's d = 2.2),其中以缺血預處理組效果量最大。結論:連續五日缺血預處理以及等長收縮運動後,皆可改善患者血壓,並且能透過心率變異性看出副交感神經活性增加。本研究認為,上述兩種方式皆屬於改善血壓的非藥物治療方式,然而就執行的方便性及安全性而言,缺血預處理可能更加適合,因為被動收縮在安全上有更高的掌握性,並且器材也更簡便、更容易在居家由患者自己操作。 Background: Hypertension poses a significant public health threat, serving as a critical indicator of overall well-being and a contributory risk factor for various cardiovascular diseases. Previous research suggests that different modalities of exercise can effectively lower blood pressure, with isometric training demonstrating particular potential for reducing systolic pressure. Objectives: The present study aims to compare the effects of isometric contraction training (active contraction) and ischemic preconditioning (passive contraction) in reducing blood pressure among individuals with prehypertension. Methods: Twenty adult males (SBP: 132.9 ± 4.4 mmHg; DBP: 79.1 ± 5.5 mmHg) were recruited and randomly allocated into four groups: Control (CON), Ischemic Preconditioning (IPC), Isometric Exercise (ISO), and Mixed group (MIX). A five-day consecutive intervention was performed, followed by observations in submaximal exercise tests for blood pressure, heart rate, and heart rate variability. Data were analyzed using a two-way mixed-design ANOVA and paired sample t-tests, with a significance level set at p < .05. Results: Post-intervention systolic blood pressure changes indicated the greatest effect size in the IPC (pre vs. post, 133.3 ± 4.9 mmHg vs. 125.2 ± 3.6 mmHg, p = .00, Cohen's d = 2.7), followed by the ISO (pre vs. post, 132.5 ± 4.4 mmHg vs. 127.4 ± 4.1 mmHg, p = .00, Cohen's d = 2.1), and the MIX (pre vs. post, 132.5 ± 4.4 mmHg vs. 126.3 ± 3.1 mmHg, p = .00, Cohen's d = 2.2). Conclusion: Both ischemic preconditioning and isometric exercise were effective non-pharmacological approaches for improving healthier blood pressure. Increased parasympathetic activity was also evident through heart rate variability metrics. However, considering practicality and safety, ischemic preconditioning may be more suitable as it offers greater control over safety parameters and the convenience of home-based, self-administered intervention using simpler equipment. |
