Effects of pilates exercises on strength, endurance and muscle power in older adults: Systematic review and meta-analysis.

Introduction: Pilates exercises have been used by the older adults and have shown potential to improve some components of physical fitness.

Objective: To verify the effects of Pilates on strength, endurance and muscle power in older adults.

Methods: The searches were performed in the databases: PubMed, EMBASE, CENTRAL, CINAHL, Web of Science, SPORTDiscus, LILACS and PEDro until September 2022, without filters that limited the date of publications or language. The studies included were: randomized clinical trials (RCTs); interventions that used Pilates; interventions with outcomes involving strength, endurance and/or muscle power; participants over 60 years old.

Results: 24 RCTs (1190 participants) were selected. There is low quality evidence that Pilates did not significantly improve muscle strength compared to the control group (Standardized Mean Difference (SMD) = 1.18 [95%CI -0.71, 3.08] I = 93%), and moderate quality compared to other exercises (SMD = 0.01 [CI95% -0.46, 0.48] I = 0%). Very low quality evidence shows that Pilates can improve muscular endurance of upper limbs compared to control group (Mean Difference (MD) = 4.87 [95%CI 2.38, 7.36] I = 88%) and lower limbs compared to other exercises (MD = 2.68 [CI95% 0.26, 5.10] I = 87%). It was not possible to perform muscle power analysis due to the reduced number of studies.

Conclusion: Currently, it is not feasible to recommend Pilates exercises as a means to improve strength, endurance and muscle power in the older adults. More RCTs covering this topic are needed given the low quality of evidence available at this time.
