OBJECTIVE: This study aimed to ascertain the physical-fitness trends among community-dwelling older adults using performance testing. The results of the evaluation conducted during the COVID-19 pandemic were compared to data from the pre-pandemic period.
METHODS: A total of 240 community-dwelling older adults who participated in a health checkup program from 2016-2020 underwent the following tests: grip strength (upper limb muscle), single-leg balance with eyes open (static balance), sit-and-reach test (flexibility), timed up-and-go test (TUG, functional mobility), 5 meter habitual walk (walking ability), and hand working with pegboard (hand dexterity). Linear mixed effect models were applied to the hierarchical dataset: repeated data (Level 1), pre-pandemic (2016-2019), pandemic (2019-2020) (Level 2), and individuals (Level 3). Fixed effects and interactions were estimated for the survey year (Level 1), and between the survey year and pre- and post-pandemic (Level 2), with the range of decline set measured in terms of its standardized partial regression coefficient, "B," from 2019-2020.
RESULTS: The items for which significant cross-level interactions were identified. In males, the following items showed significant cross-level interactions: sit and reach test (B=-2.56, 95% CI: -4.45--0.66 cm), TUG (+0.39, 0.21-0.56 sec) and 5 meter habitual walk (+0.15, 0.04-0.27 sec). In females items except single-leg balance with eyes open showed significant cross-level interactions: grip strength (-0.58, -1.11--0.05 kg), sit-and-reach test (-3.53, -5.11--1.95 cm), TUG (+0.15, 0.03-0.27 sec), for 5 meter habitual walk (+0.14, 0.04-0.24 sec), and hand working with pegboard (+0.89, 0.28-1.51 sec).
CONCLUSION: In both males and females, a significant deterioration in flexibility and mobility movement ability was observed in 2019-2020. In addition, upper limb muscle strength and hand dexterity movement deteriorated in females.
