Active Older Adults Keep Aerobic Capacity and Experience Small Reductions in Body Strength During Confinement Due to COVID-19 Outbreak

摘要

The objective of this study was to observe the home-confinement effects on physical fitness, physical activity (PA), and body composition in active older adults, and to compare physical fitness and PA according to quality of life (QoL) during confinement. A total of 72 physically active older adults (61.1% females; 74.24 ±5.57 years) were assessed pre- and postconfinement for aerobic capacity (6-min walk test), lower (30-s sit-to-stand), and upper (30-s arm-curl) body strength, PA (short-version of the International Physical Activity Questionnaire), and QoL (EQ-5D-visual analogue scale). The pre- and postconfinement comparisons show declines in upper (-2.24±0.45 repetitions; p<.001; eta~2 = .276) and lower body strength (-2.65±0.42 repetitions; p < .001; eta~2 = .378) in both genders, but not in aerobic capacity. Ninety percentage of older adults perceived a decline in PA. Older adults reporting high QoL increased 19.27 ± 97.04 m in the 6-min walk test, while the participants with low QoL reduced 28.32 ±63.27 m (p = .018; eta~2 = .090). Previously active older adults did not have their aerobic capacity decrease significantly despite a decline in upper and lower body strength during an 11-week home confinement period.
