The study investigated the effect of whole-body vibration (WBV) alone and in association with localized radiofrequency on fat deposits in young nonobese subjects.
Forty-four (44) healthy, nonobese women aged 25.3±5.26 years, body-mass index (BMI) 21.7±2.47 kg/m(2) were randomly assigned to an 8-week trial of WBV (2 sessions per week) or WBV plus localized radiofrequency (WBV+RF) in the abdominal, buttock, and thigh region. Anthropometry, body composition (dual-energy x-ray absorptiometry, DXA), and motor performance were assessed before and after the trial. Data were analyzed by one-way analysis of variance (ANOVA) or ANOVA for repeated measures (group×time).
Valid data were obtained for 36 women (WBV, n=18; WBV+RF, n=18). Body mass and BMI did not change after trial. Body circumferences were unchanged or slightly reduced, with no difference between groups. Skinfold thickness was significantly reduced at several sites in the whole study population (n=36), reduction being higher at the thigh site in the WBV+RF group. According to DXA analysis, total body lean mass increased (p=0.009) and total body fat mass decreased (p=0.036) in the whole study population after trial with no significant difference between the WBV and WBV+RF group in spite of larger absolute changes in the latter. Standing long jump improved after trial with no change in flamingo balance test.
An 8-week WBV training is effective in inducing positive body composition changes as well as increased muscle strength in women; it could be recommended as an alternative/complementary tool in physical activity or fitness programs as it is well tolerated. The current data give limited support to the association of localized RF treatment and WBV training as synergistic in inducing body fat mass loss; such a beneficial effect should be further investigated in subject with larger subcutaneous fat deposits (i.e., overweight or obese).
本研究旨在探讨全身振动（WBV）单独应用及与局部射频联合应用对年轻非肥胖受试者脂肪沉积的影响。
44 名健康、非肥胖的年轻女性（年龄 25.3±5.26 岁，BMI 21.7±2.47 kg/m2）参与了为期 8 周的全身振动（每周 2 次）或全身振动联合局部射频（WBV+RF）治疗，试验部位为腹部、臀部和大腿。试验前后对人体测量学、身体成分（双能 X 射线吸收法，DXA）和运动表现进行评估。数据采用单因素方差分析（ANOVA）或重复测量方差分析（组间×时间）进行分析。
共有 36 名女性（WBV 组，n=18；WBV+RF 组，n=18）的数据有效。试验后体重和 BMI 无变化。身体围度不变或略有减少，组间无差异。全身皮肤褶皱厚度在整个研究人群中均显著降低（n=36），WBV+RF 组大腿部位的降幅更高。根据 DXA 分析，整个研究人群在试验后总身体瘦体重增加（p=0.009），总身体脂肪量减少（p=0.036），尽管后者的绝对变化更大，但 WBV 和 WBV+RF 组之间没有差异。试验后，立定跳远成绩提高，而弗拉明戈平衡测试无变化。
8 周的全身振动训练可有效诱导女性身体成分的积极变化，并增强肌肉力量；因其具有良好的耐受性，可作为体育活动或健身计划中的替代/补充手段。目前的数据仅为局部射频治疗与全身振动训练联合应用可协同减少体脂肪量提供有限的支持；这种有益的效果应在皮下脂肪堆积较多的人群（即超重或肥胖者）中进一步研究。
