BACKGROUND
We examined the effect of power training on habitual, intervention and total physical activity (PA) levels in older adults with type 2 diabetes and their relationship to metabolic control.
MATERIALS AND METHODS
103 adults with type 2 diabetes were randomized to receive supervised power training or sham exercise three times/week for 12 months. Habitual, intervention, and total PA, as well as insulin resistance (HOMA2-IR) and glycosylated hemoglobin (HbA1c), were measured.
RESULTS
Participants were aged 67.9 ± 5.5 yrs, with well-controlled diabetes (HbA1c = 7.1%) and higher than average habitual PA levels compared to healthy peers. Habitual PA did not change significantly over 12 months ( = 0.74), and there was no effect of group assignment on change over time in habitual PA over 0-6 ( = 0.16) or 0-6-12 months ( = 0.51). By contrast, intervention PA, leg press tonnage and total PA increased over both 6- and 12-month timepoints ( = 0.0001), and these changes were significantly greater in the power training compared to the sham exercise group across timepoints ( = 0.0001). However, there were no associations between changes in any PA measures over time and changes in metabolic profile.
CONCLUSION
Structured high-intensity power training may be an effective strategy to enhance overall PA in this high-risk cohort.
背景
我们研究了力量训练对2型糖尿病老年人的日常、干预和总体身体活动（PA）水平的影响及其与代谢控制的关系。
材料与方法
103名2型糖尿病成年人被随机分为三组，分别接受每周三次、为期12个月的有监督的力量训练或假运动。测量了日常、干预和总体PA水平，以及胰岛素抵抗（HOMA2-IR）和糖化血红蛋白（HbA1c）。
结果
参与者年龄为67.9±5.5岁，糖尿病控制良好（HbA1c = 7.1%），与健康同龄人相比，日常PA水平高于平均水平。12个月内日常PA没有显著变化（ = 0.74），在0至6个月（ = 0.16）或0至6至12个月（ = 0.51）期间，分组对日常PA随时间的变化没有影响。相比之下，干预PA、腿部推举吨位和总体PA在6个月和12个月的时间点均有所增加（ = 0.0001），在各个时间点，力量训练组的这些变化显著大于假运动组（ = 0.0001）。然而，任何PA测量值随时间的变化与代谢指标的变化之间均无关联。
结论
结构化的高强度力量训练可能是提高这一高危人群总体PA的有效策略。
