Effects of grouped versus alternating functional training on the shoulder girdle and lumbar-pelvic girdle stability: a randomised controlled trial
Keywords:knee osteoarthritis, balance test, reproducibility
The present research aimed to verify the effect of 10 weeks of structured FT grouped by muscular actions (GFT) or alternating actions (AFT) on scapular and lumbar-pelvic girdle stability. One hundred and twenty adults (60 men; 60 women) were allocated into three groups, GFT (n= 40) that performed the actions in sequence (squat - squat - pull - pull), AFT (n= 40) that performed alternate actions (squat - pull - squat - pull) and the control group (CG, n= 40). The shoulder girdle and pelvic girdle stability were assessed using the Octobalance Upper Body Test. The GFT increased stability after the intervention and compared to the CG (p= 0.003) as assessed by the relative range of the right (ES= 0.53) and left (ES= 0.57) hemispheres. Besides, most results were within the instrument's error value and the magnitude of the effect was moderate to trivial among the experimental groups. Conclusions: Therefore, ten weeks of functional training performed in a grouped sequence promoted improvements in scapular and lumbar-pelvic girdle stability.
