The aim of this study was to investigate the effectiveness of walking with Equipment for Clever Exercise (ECE PEDO) compared to supervised, moderate-intensity, aerobic, treadmill walking exercise in overweight and obese women.
Between September 2014 and January 2015, 28 women with overweight and obesity were assigned to two groups: supervised treadmill walking (Group 1, n=14) or walking with ECE PEDO (Group 2, n=14). The target heart rate (HR) corresponding to values of 50 to 70% VO2max were determined by submaximal treadmill test. Group 1 was instructed walking at their target HR on treadmill. The number of steps in a min corresponding to the target HR was calculated by a criterion pedometer and Group 2 was instructed walking in this step range recorded to the ECE PEDO giving audible feedback. Before and after a 12-week exercise program, all participants were evaluated by Body Mass Index (BMI) and waist circumference (WC). Ultrasonographic visceral fat thickness (VFT) and ergospirometric VO2max.
The VFT decreased in both walking groups in association with reduced WC and weight loss and also significant increases in the VO2max after exercise intervention (p<0.05). The VFT decreased only in women by walking with ECE PEDO compared to the other group (p<0.05).
Our study results showed that both moderate-intensity exercise provided by a novel pedometer and supervised treadmill walking showed significant improvements in abdominal obesity and VO2max.
本研究旨在调查与在监督下进行的中等强度有氧跑步机步行运动相比，使用智能运动设备（ECE PEDO）步行对超重和肥胖女性的有效性。
2014年9月至2015年1月期间，28名超重和肥胖女性被分为两组：监督下的跑步机步行组（第1组，n = 14）或使用ECE PEDO步行组（第2组，n = 14）。通过次极量跑步机测试确定对应于50%至70%最大摄氧量（VO2max）值的目标心率（HR）。第1组被指导在跑步机上以其目标心率行走。通过标准计步器计算对应目标心率的每分钟步数，第2组被指导在记录到ECE PEDO并给予听觉反馈的此步幅范围内行走。在为期12周的运动计划前后，所有参与者均通过体重指数（BMI）和腰围（WC）进行评估。超声内脏脂肪厚度（VFT）和运动肺量计测定的VO2max。
两个步行组的VFT均下降，同时WC减小且体重减轻，运动干预后VO2max也显著增加（p<0.05）。与另一组相比，仅使用ECE PEDO步行的女性VFT下降（p<0.05）。
我们的研究结果表明，新型计步器提供的中等强度运动和监督下的跑步机步行在腹部肥胖和VO2max方面均有显著改善。
