目前在该领域还没有广泛适用于中老年人群的高依从性和高有效性的长期运动训练方案。我们评估了长期训练计划的依从性和效果，包括间歇步行训练（IWT）和信息技术网络系统，以及影响依从性的因素。中老年男性和女性[n = 696，年龄65 +/- 7(SD) yr]接受IWT。受试者被要求分别在>= 70和40%步行峰值有氧能力（（o2峰值））下重复5组或更多的快走和慢走，每组3分钟。每天>= 4天/周，持续22个月。依从性评估为相对于22个月内4天/周的目标完成的训练天数。对（o2峰值）和生活方式相关疾病评分的影响每6个月评估一次。在调整基线身体特征和其他可能的协变量（包括加压素V1a受体多态性）后，通过多元回归分析评估影响依从性的独立因素。22个月以上的依从性平均为70%，与生活方式相关疾病评分降低13% （R-2 = 0.94, P = 0.006）和（o2峰值）增加12% （R-2 = 0.94, P = 0.006）高度相关。较高依从性的主要决定因素是较低的基线体重指数（BMI） （P < 0.0001）和男性性别（P < 0.0001）。对于男性，除了BMI，不吸烟者（P = 0.031）和V1a受体多态性（P = 0.033）是高依从性的独立决定因素。因此，长期IWT计划是一种有效的方案。此外，所有受试者的基线BMI和性别，以及男性吸烟和V1a受体多态性与依从性有关。
No long-term exercise training regimen with high adherence and effectiveness in middle-aged and older people is broadly available in the field. We assessed the adherence to, and effects of, our long-term training program comprising an interval walking training (IWT) and an information technology network system and the factors affecting adherence. Middle-aged and older men and women [n = 696, aged 65 +/- 7(SD) yr] underwent IWT. The subjects were instructed to repeat five or more sets of fast and slow walking for 3 min each at >= 70 and 40% peak aerobic capacity for walking ((O2peak)), respectively, per day >= 4 days/wk for 22 mo. Adherence was assessed as training days accomplished relative to the target of 4 days/wk over 22 mo. The effects on the (O2peak) and lifestyle-related disease score were evaluated every 6 mo. The independent factors affecting adherence were assessed by multiple-regression analysis after adjustment for baseline physical characteristics and other possible covariates, including vasopressin V1a receptor polymorphisms. The adherence over 22 mo averaged 70% and was highly correlated with a 13% reduction in the lifestyle-related disease score (R-2 = 0.94, P = 0.006) and with a 12% increase in (O2peak) (R-2 = 0.94, P = 0.006). The major determinant of higher adherence was lower baseline body mass index (BMI) (P < 0.0001) and male sex (P < 0.0001). For men, in addition to BMI, nonsmokers (P = 0.031) and V1a receptor polymorphisms (P = 0.033) were independent determinants of higher adherence. Thus the long-term IWT program is an effective regimen. Moreover, baseline BMI and sex for all subjects, and smoking and V1a receptor polymorphisms for men, were associated with adherence.
