RESUMEN

BACKGROUND: and Purpose: Pilates exercises have been recommended to improve postural balance and reduce the risk of falls in older adults. However, the certainty of these recommendations remains unclear. In this sense, our objective was to update the literature and verify the effects of Pilates on postural balance and the risk of falls in this population. METHODS: A systematic search was conducted across multiple databases, including PubMed, EMBASE, CENTRAL, CINAHL, Web of Science, SPORTDiscus, LILACS, and PEDro, on April 17, 2023. The methodological quality of the studies was assessed using the PEDro scale, and the certainty of evidence was evaluated using the GRADE system. Meta-analysis calculations were performed by standardized mean difference (SMD). RESULTS: A total of 39 studies, involving 1770 participants, were included in the systematic review. Only 14 studies exhibited satisfactory methodological quality. Evidence with very low to moderate certainty showed that Pilates was significantly superior to control groups on indicators of dynamic postural balance (SMD = 1.60 to 0.72), static postural balance (SMD = 0.37 to 0.25), and general state of balance (SMD = 0.76), but not to reduce the number and fear of falls. Furthermore, Pilates was comparable to other forms of exercise for these outcomes. CONCLUSIONS: Pilates can be recommended to enhance static and dynamic postural balance in older adults, but not to reduce the number of falls or the fear of falling. Given that no outcomes showed high certainty of evidence, future studies may alter these findings.

RESUMEN

INTRODUCTION: The effects of stretching exercises on muscle strength have been widely researched in the literature, however, there are no studies investigating the effects of Pilates stretching. OBJECTIVE: To compare the effects of static stretching and Pilates stretching on the concentric muscle strength of the knee extensors and flexors. METHOD: 102 trained young adults were randomized into three groups: static stretching (n = 33); Pilates stretching (n = 34); control (n = 35). Isokinetic evaluation of the knee extensor and flexor muscles was performed at 60°/s and 180°/s, pre and post acute intervention with stretching. Interventions in the static stretching and Pilates stretching groups occurred in 3 sets x 30 s for each body region considered (a-knee extensor muscles; b-knee flexor muscles). The control group did not perform any intervention. RESULTS: No difference (p > 0.05) was observed between the groups after the intervention. There was only a significant intragroup improvement for the control group on the isokinetic muscle strength of the knee flexors at 180°/s, with a moderate effect size, considering the entire sample (p = 0.040; d = 0.42) and when considering only male gender (p = 0.010; d = 0.60). CONCLUSION: Static stretching or Pilates stretching performed as a warm-up did not impair or enhance the concentric muscle strength performance of the knee extensors and flexors. In this way, both forms of stretching can be considered as preparatory exercises before muscle strength training.

RESUMEN

BACKGROUND: The scientific literature questions the impact of stretching exercises performed immediately before muscle strengthening exercises on different components of musculoskeletal physical fitness. Pilates is a physical exercise modality that typically uses stretching exercises preceding muscle-strengthening exercises. However, no studies have investigated the effects of stretching in a Pilates program on components of musculoskeletal fitness. The aim of the present study was to verify the effects of stretching in a Pilates exercise program on flexibility, strength, vertical jump height and muscular endurance. METHODS: Thirty-two sedentary young women were randomized into two groups: traditional Pilates (TP), who performed flexibility and muscle strengthening exercises (n = 16), and nontraditional Pilates (NTP), who only performed muscle-strengthening exercises (n = 16). Sessions took place 3 times a week for 8 weeks. The following tests were performed pre- and postintervention: 10-RM knee extensors, vertical jump, handgrip, 1-min sit-ups, Sorensen and sit-and-reach. The occurrence of adverse events was recorded throughout the intervention and compared between groups using odds ratio (OR). To compare the results of motor tests between groups, ANCOVA or Mann‒Whitney U test was used for parametric and nonparametric data, respectively. The data were analyzed by intention-to-treat. RESULTS: After intervention, the TP was superior to NTP for the sit-and-reach test, with a large effect size (d = 0.87; p = 0.035), with no differences between groups for the other tests. Intragroup comparisons showed significant differences (p < 0.05) for TP and NTP for improvement in 10-RM knee extensors and vertical jump measurements, while only TP showed significant intragroup improvement (p < 0.05) for the sit-and-reach test. A greater chance of experiencing pain or other discomfort as a result of exercise was shown by NTP (OR = 4.20, CI95% 0.69 to 25.26). CONCLUSION: Our findings demonstrated that stretching exercises performed at the beginning of sessions in a Pilates program did not impair or enhance the development of strength, vertical jump height and muscular endurance in young women. However, only the Pilates program with stretching improved flexibility and reduced the chances of adverse events such as musculoskeletal pain and other discomfort resulting from the exercise protocol.
