Forty‐seven community‐dwelling older adults aged >70 years participated in this Japanese cross‐sectional study to determine the relationship between the isometric lower extremity muscle strength measured during knee extension (KE) in single‐joint and total leg extension (TLE) in multi‐joint tasks, physical performance tests, and functional status. The physical performance was determined by KE and TLE muscle strength, walking capacity, and balance performance tests, while the functional status was evaluated by interview using basic activities of daily living (ADL) and instrumental activities of daily living (IADL) tools. The results indicated that the TLE muscle strength was significantly related to all the other performance tests, while the KE muscle strength was not correlated with the balance test. Also, the bilateral TLE muscle strength was significantly associated with IADL status compared with the KE muscle strength. In conclusion, multi‐joint muscle strength testing might be superior to single‐joint muscle strength testing for the screening of the functional impairments of older adults.
