To verify the effects of two different detraining periods on the physical fitness of older adults with cardiometabolic risk factors.
This observational study encompassed older individuals with cardiometabolic risk factors, who were assessed after two different detraining periods: 1 month (1DT) and 3 months (3DT). Physical fitness was assessed using the 30-s sit to stand test (STS), 30-s arm curl, chair sit-and-reach, back scratch, timed up and go, and 6-min walk test (6MWT). The comparison between the different periods was carried out using absolute differences (Δ = posttest-pretest) and relative differences (Δ% = (Δ/pretest) × 100), with α = 0.05.
Eight older adults were assessed (70.3 ± 7.48 years, 4 female/4 male). Improvements in the STS (+1.88 repetitions; = 0.007) and 6MWT (+17.38 m; = 0.007) were found after 1DT. After 3DT, a worsening was observed in the 6MWT (-26.38 m; = 0.018). The arm curl test worsened in both detraining periods (1DT: -1.38 repetitions; 3DT: -3.5 repetitions; = 0.001). When comparing Δ% of 1DT and 3DT, STS and 6MWT showed differences, with = 0.024 and = 0.005, respectively.
The 1-month detraining period had a positive effect on some physical fitness components, while 3 months induced a decline in cardiorespiratory fitness. Upper limb strength appears to be the component most susceptible to detraining.
验证两种不同停训期对患有心脏代谢危险因素的老年人身体素质的影响。
这项观察性研究纳入了患有心脏代谢危险因素的老年人，他们在两个不同的停训期后接受评估：1个月（1DT）和3个月（3DT）。使用30秒坐立试验（STS）、30秒手臂弯举、椅子坐位体前屈、背部伸展、计时起立行走和6分钟步行试验（6MWT）评估身体素质。使用绝对差异（Δ=后测-前测）和相对差异（Δ%=（Δ/前测）×100）进行不同时期之间的比较，α=0.05。
评估了8名老年人（70.3±7.48岁，4名女性/4名男性）。1DT后，STS（增加1.88次重复；P=0.007）和6MWT（增加17.38米；P=0.007）有所改善。3DT后，6MWT出现恶化（减少26.38米；P=0.018）。在两个停训期内，手臂弯举试验均恶化（1DT：减少1.38次重复；3DT：减少3.5次重复；P=0.001）。比较1DT和3DT的Δ%时，STS和6MWT存在差异，P分别为0.024和0.005。
1个月的停训期对某些身体素质成分有积极影响，而3个月则导致心肺适能下降。上肢力量似乎是最易受停训影响的成分。
