We aimed toinvestigate the predictive validity of motor fitness and flexibility tests in relation to health outcomesin adults and older adults. Web of Science and PubMed databases were screened for studies publishedfrom inception to November 2020. Two authors systematically searched, evaluated, and extracteddata from identified original studies and systematic reviews/meta-analysis. Three levels of evidencewere constructed: strong, moderate, and limited/inconclusive evidence. In total, 1182 studies wereidentified, and 70 studies and 6 systematic reviews/meta-analysis were summarized. Strong evidenceindicated that (i) slower gait speed predicts falls and institutionalization/hospitalization in adultsover 60 years old, cognitive decline/impairment over 55 years old, mobility disability over 50 yearsold, disability in instrumental activities of daily living (IADL) over 54 years old, cardiovasculardisease risk over 45 years old, and all-cause mortality over 35 years old; (ii) impaired balance predictsfalls and disability in IADL/mobility disability in adults over 40 years old and all-cause mortalityover 53 years old; (iii) worse timed up&go test (TUG) predicts falls and fear of falling over 40 yearsold. Evidence supports that slower gait speed, impaired balance, and worse TUG performance aresignificantly associated with an increased risk of adverse health outcomes in adults.
