Trekking includes downhill walking and enhances lower limb strength. Muscle fitness is a predictor of mortality and is associated with cardiovascular risk factors in adults. The purpose of this study was to investigate the effects of trekking on cardiovascular health and fitness in older obese women. The participants were randomly assigned to an exercise group (EG, n= 32) and a control group (CG, n= 48). The EG participated in the trekking program for 12 weeks, 3 times per week, and 90 min per session, at a moderate intensity. Cardiovascular health (BMI, percentage of body fat, blood pressure, glucose, triglycerides, and total cholesterol) and fitness (muscle strength, muscle endurance, balance, and flexibility) were measured before and after the 12-week program. A twoway repeated ANOVA was used to compare and analyze the group differences. Body weight, systolic blood pressure, and muscle strength were significantly different between the groups. These results indicate that trekking played a significant role in the reduction of weight and systolic blood pressure in obese women. The results of this study can be utilized to reduce cardiovascular risk factors associated with aging.
徒步旅行包括下坡行走，可增强下肢力量。肌肉健康是死亡率的一个预测指标，并且与成年人的心血管危险因素相关。本研究的目的是调查徒步旅行对老年肥胖女性心血管健康和体能的影响。参与者被随机分为运动组（EG，n = 32）和对照组（CG，n = 48）。运动组参加为期12周的徒步旅行计划，每周3次，每次90分钟，强度适中。在为期12周的计划前后测量心血管健康状况（体重指数、体脂百分比、血压、血糖、甘油三酯和总胆固醇）和体能（肌肉力量、肌肉耐力、平衡能力和柔韧性）。使用双向重复方差分析来比较和分析组间差异。两组之间的体重、收缩压和肌肉力量存在显著差异。这些结果表明，徒步旅行在肥胖女性体重减轻和收缩压降低方面发挥了重要作用。本研究结果可用于降低与衰老相关的心血管危险因素。
