    This systematic review and meta-analysis aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports (OCS), compared with active/passive controls, on balance, fall risk, or falls in older adults. The TESTEX and GRADE scales assessed the methodological quality and certainty of the evidence. The protocol was registered in PROSPERO (code: CRD42020204034). From 1496 records, eight studies were included, involving 322 older adults (64% female; mean age = 71.1 years). The TESTEX scale revealed all studies with a score ≥ 60% (moderate-high quality). The GRADE scale indicated all studies with at least some concerns, up to a high risk of bias (i.e., was rated very low). Meta-analyses were planned, although the reduced number of studies precluded its incorporation in the final manuscript. Only two from six studies that assessed balance found improvements after OCS compared to controls. No differences were found between OCS vs. control groups for fall risk or falls. The available evidence does not allow a definitive recommendation for or against OCS interventions as an effective strategy to improve balance and reduce the fall risk or falls in older adults. Therefore, more high-quality studies are required to draw definitive conclusions.

    Effects of active exergames training on physical functional performance in older females

    Objective: To analyze the effects of 8 weeks of an active exergames training program on walking speed, static balance, timed up-and-go test, and sit-to-stand performance in older females. Methods: Two groups of participants were formed by block-design randomization as follows: (i) control group (n=12; age, 74.1±7.9 years); (ii) 8 week exergames training group (n=13; age, 75.6±9.1 years). Training was undertaken three times per week, including athletic, bowling and table tennis exergames. Each exergame had a duration of 8 min, with 2 min of recovery between exergames. The intensity of the training sessions was controlled using the 10-point rating of perceived exertion scale. Results: Group×time interactions were observed for the 4 m walking speed test, static balance test, timed up-and-go test and the 5-repetition sitto- stand test (all p<0.01; d=0.46–0.80). Conclusion: Exergames training improve physical functional performance in older females. These results should be considered when designing appropriate and better training programs for older adults, since active exergames training it is an affordable and low-cost alternative for community centres and preventive health units working with this population.
