Incorporating agility-like training aspects (coordination, changes of direction and velocity) into MT may further enhance physical outcomes highly relevant for activities of daily living. This meta-analysis investigated the effects of multimodal agility-like exercise training (MAT) on physical and cognitive performance compared to inactive (IC) and active controls (AC) in older adults. METHODS: Literature search was conducted in four health-related databases (PubMed, SCOPUS, SPORTDiscus and Web of Science). Randomized controlled trials with pre-post testing applying MAT (including aspects of training with at least two different traditional domains: strength, balance, endurance) and an agility-like component in community-dwelling older adults were screened for eligibility. Standardized mean differences (SMD) adjusting for small sample sizes (hedges' g) were used to extract main outcomes (strength, gait, balance, mobility, endurance, cognition).
