O efeito do treinamento funcional e resistido sobre a postura e as dores nas costas

Abstract

Back pain is a common, disabling and multifactorial disease. Arounded 75 to 80% of the population will suffer from at least one episode of back pain during life, according estimative. Several academies offer postural assessments to their clients, as well as guidelines for activities that may help increase muscle tone, contribute to reducing deviations and postural changes, as well as back pain episodes in these people. Among the activities offered, we there are the resistance training (TR) and functional training (TF). The aim of the present study was to identify the effects of resistance training and functional training on postural changes and back pain in their practitioners. The quasi-experimental quantitative methodology was used. Thus, 12 individuals with episodes of back pain, female, aged between 18 and 50 years participated in this study. The sample was divided into two groups: the resistance training practitioners (PTR, n = 6) and the functional training practitioners (TFP, n = 6). The information was obtained through evaluations performed by a single researcher, which occurred in the afternoon or evening. Each postural evaluation lasted an average of 30 minutes, performed one prior to the intervention, and another after the intervention. The questionnaires of location and intensity of back pain were also applied. To verify the influence of 12 weeks of resistance training or functional training on their practitioners, postural assessment data and disability and intensity of back pain were compared (pre and post) through two way mixed ANOVA. The student's t test was applied to identify where statistical differences will occur. The variables were tested with a significance level of p <0.05, using to all analyzes the Statistical software version 5.5. Significant differences were found in the lumbar region in the practitioners of TF, the average found in pre-training was 30 ± 12.92 degrees, and in the post-training was 42 ± 10.92 degrees, indicating a p = 0.03. In the RT there were no significant differences. At egion of the thoracic spine, no significant differences were found in any of the practices. Changes in pain level were observed only in TF practitioners, from 4 points on the back pain scale in the pretraining to 2 points in the post-training (p <0.05; F = 20.34). The present study aimed to identify the effects of resistance training and functional training on the posture and back pain of its practitioners, with the most effective functional training, in which significant differences were found in the measurements of the lumbar angulations and reductions in lower back pain.
