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. Therefore, ten weeks of functional training performed in a grouped sequence promoted improvements in scapular and lumbar-pelvic girdle stability.
