Abstract: Objective: To verify the effects of two different detraining periods on the physical fitness of older adults with cardiometabolic risk factors. Methods: 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. Results: Eight older adults were assessed (70.3 ± 7.48 years, 4 female/4 male). Improvements in the STS (+1.88 repetitions; p = 0.007) and 6MWT (+17.38 m; p = 0.007) were found after 1DT. After 3DT, a worsening was observed in the 6MWT (−26.38 m; p = 0.018). The arm curl test worsened in both detraining periods (1DT: −1.38 repetitions; 3DT: −3.5 repetitions; p = 0.001). When comparing Δ% of 1DT and 3DT, STS and 6MWT showed differences, with p = 0.024 and p = 0.005, respectively. Conclusions: 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.
