Abstract:
OBJECTIVE: To compare the effectiveness of strength versus endurance training on reducing visceral fat in individuals with obesity.
METHODS: 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.
RESULTS: Participants (aged 44 years, 74% women, body mass index: 37 kg/m2, mean VAT volume: 4050 cm3) 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).
CONCLUSIONS: Despite heterogeneous individual training responses, strength and endurance training neither affected VAT volume nor key secondary endpoints differently.
摘要:
目的:比较力量训练和耐力训练对肥胖个体减少内脏脂肪的效果。
方法:对于强度与耐力(STEN)24个月的随机临床试验,我们将239名腹部肥胖的参与者分配到力量或耐力训练(每周两到三次,60分钟/培训课程)以及标准的营养咨询,以促进健康饮食。将12个月后通过磁共振成像量化的腹部内脏脂肪组织(VAT)面积的变化定义为主要终点。
结果:参与者(44岁,74%的女性,体重指数:37kg/m2,平均增值税体积:4050cm3)在12个月时的保留率约为50%,良好的培训计划依从性为30%。12个月和24个月后,VAT体积动力学的力量和耐力训练之间没有差异(p=0.13)。只有在良好的依从性组中,我们才发现两种培训方案中增值税减少的趋势。独立于锻炼计划,腹部皮下AT容量中度下降的趋势是持续的,身体脂肪量,体重指数和胰岛素敏感性参数的改善。尽管两种运动干预措施的身体素质参数都有所改善,静息能量消耗的动态,干预组之间的糖和脂代谢参数没有差异,并且在2年试验期间没有显着改善(p>0.05)。
结论:尽管个体训练反应不同,力量和耐力训练对增值税量和关键次要终点的影响都不不同。
