To compare the effectiveness of strength versus endurance training on reducing visceral fat in individuals with obesity.
For the STrength versus ENdurance (STEN) 24-month randomized clinical trial, we assigned 239 participants with abdominal obesity to either strength or endurance training (two to three times a week, 60 min/training session) in addition to standard nutritional counselling to promote a healthy diet. Changes in abdominal visceral adipose tissue (VAT) area quantified by magnetic resonance imaging after 12 months were defined as a primary endpoint.
Participants (aged 44 years, 74% women, body mass index: 37 kg/m, mean VAT volume: 4050 cm) had an approximately 50% retention rate and a 30% good training programme adherence at 12 months. There was no difference between strength and endurance training in VAT volume dynamics after 12 and 24 months (p = .13). Only in the good adherence group did we find a trend for reduced VAT volume in both training regimens. Independently of the exercise programme, there was a continuous trend for moderate loss of abdominal subcutaneous AT volume, body fat mass, body mass index and improved parameters of insulin sensitivity. Although parameters of physical fitness improved upon both exercise interventions, the dynamics of resting energy expenditure, glucose and lipid metabolism parameters were not different between the intervention groups and did not significantly improve during the 2-year trial (p > .05).
Despite heterogeneous individual training responses, strength and endurance training neither affected VAT volume nor key secondary endpoints differently.
比较力量训练与耐力训练对肥胖个体减少内脏脂肪的效果。
在为期 24 个月的 STrength versus ENdurance（STEN）随机临床试验中，我们将 239 名患有腹型肥胖的参与者分配到力量训练或耐力训练组（每周两次到三次，每次 60 分钟/训练课程），此外还进行标准的营养咨询以促进健康饮食。12 个月后通过磁共振成像（MRI）定量评估腹部内脏脂肪组织（VAT）面积的变化，将其定义为主要终点。
参与者（年龄 44 岁，74%为女性，体重指数为 37kg/m2，平均 VAT 体积为 4050cm3）的保留率约为 50%，12 个月时的良好训练计划依从率为 30%。12 个月和 24 个月时，VAT 体积的变化在力量训练和耐力训练之间没有差异（p=0.13）。仅在良好依从组中，我们发现两种训练方案均有 VAT 体积减少的趋势。无论运动方案如何，均有中等程度的腹部皮下脂肪组织、体脂肪量、体重指数减少以及胰岛素敏感性改善的趋势。尽管两种运动干预都改善了身体适应性参数，但静息能量消耗、血糖和脂质代谢参数的动态变化在干预组之间没有差异，并且在 2 年的试验中没有显著改善（p＞0.05）。
尽管存在个体训练反应的差异，但力量训练和耐力训练对 VAT 体积或其他次要终点没有不同的影响。
