Nordic walking (NW) is a potentially beneficial exercise strategy for overweight and obese people. To date, no reviews have synthesized the existing scientific evidence regarding the effects of NW on this population. This systematic review and meta-analysis aimed to identify the characteristics, methodological quality, and results of the investigations that have studied the effects of NW in overweight and obese individuals.
Six electronic databases were searched up to June 2019 for studies that examined the effects of NW on people with a body mass index ≥ 25 kg/m2. The methodological quality of the included randomized controlled trials was retrieved from the physiotherapy evidence database or evaluated using the physiotherapy evidence database scale.
Twelve studies were included in the review. The investigations were mostly good-to-fair methodological quality. NW groups had a significant improvement on parameters such as fasting plasma glucose, abdominal adiposity, and body fat compared with the baseline, but no significant improvements were found when compared with control groups.
NW can potentially lead to improvements in parameters related to major health outcomes in overweight and obese people. The lack of control for confounding variables in the analyzed studies prevents further elaboration on its potential benefits.
北欧健走（Nordic walking，NW）是一种对超重和肥胖人群有益的运动策略。迄今为止，尚无综述综合了有关 NW 对该人群影响的现有科学证据。本系统评价和荟萃分析旨在确定研究 NW 对超重和肥胖个体影响的研究的特征、方法学质量和结果。
截至 2019 年 6 月，我们检索了六个电子数据库，以寻找评估 NW 对 BMI≥25kg/m2 的人群影响的研究。使用物理治疗证据数据库或物理治疗证据数据库量表评估纳入的随机对照试验的方法学质量。
共纳入 12 项研究。这些研究的方法学质量大多为良好至中等。与基线相比，NW 组的空腹血糖、腹部肥胖和体脂等参数有显著改善，但与对照组相比，无显著改善。
NW 可能会改善超重和肥胖人群的主要健康结局相关参数。分析研究中缺乏对混杂变量的控制，限制了对其潜在益处的进一步阐述。
