Comparison between low back strenght before and after intense strenght training in sedentary, healthy and diabetics individuals with low back pain
Abstract
Introduction: Low back pain influences body movements. Aim: The aim of this study was to evaluate comparing the paravertebral low back muscle strength between sedentary men and diabetics type 2 (T2DM) that had unspecific low back pain before and after an acute intense resistance training (RT) session. Methodology: The study had a cross-sectional and interventional character. 20 men were selected and divided into 2groups with 10 individuals each, 10 diabetic (D) and 10 constituted the control group (CON). All underwent the RT at 75% of the maximum load Results: The main results presented for the CON group handgrip pre 97 ± 26.26 vs handgrip post 96.5 ± 25.17 kgf, p= 0,8227 and the group D handgrip pre vs 75 ± 19.57 post handgrip 76 ± 20.65 kgf, p= 0.5911. Comparisons between pre, post and variation (V) among groups were made, but there was no significant intergroup difference (pre p= 0.1089, post p= 0.1275 and V p = 0.1934). Discussion: These results indicate that sedentary individuals with T2DM and nonspecific low back pain do not have significant changes in lumbar muscle strength compared to sedentary individuals. It is not the presence of the pathology of diabetes or back pain that aggravates and compromises the reduction of the strength or even that acts in favour of paravertebral musculature. Conclusion: Sedentary individuals who have T2DM and nonspecific low back pain have similar capacity to produce force in the lumbar paravertebral musculature such as sedentary healthy people before or after implementation of acute intense RT.
