Impacto de um programa de exercícios resistidos na prevalência de dor osteomuscular em adultos e idosos

Abstract

The present study addresses the effects of resistance exercises on musculoskeletal pain in adults and the elderly. Objective: To verify the impact of a resistance exercise program on the prevalence of musculoskeletal pain in adults and the elderly. Method: Uncontrolled intervention study conducted with 21 volunteers, 71.4% of whom were female, who participated in a 12-week resistance training protocol with two weekly sessions. The assessment of musculoskeletal pain was conducted using the Nordic Musculoskeletal Symptoms Questionnaire, applied before and after the intervention. Results: Although the intervention significantly reduced symptoms in the upper back (p=0.008), there was an increase in the prevalence of pain in other regions, such as the neck (p=0.003), shoulder (p=0.011), wrist and hand (p=0.022), and ankle/foot (p=0.011). The analysis of the scores did not reveal statistically significant differences in most regions, suggesting that the increases in symptoms may be associated with adaptive factors resulting from the beginning of training, as well as with pre-existing functional limitations, especially in elderly women with a history of inactivity. Conclusion: Resistance exercise may be an effective strategy to reduce localized pain, such as in the upper back region, but its effects were not effective for all body regions evaluated.
