Objective The present study aimed to examine the effects of circuit training (CT) on spine structure, trunk muscle endurance, and balance in healthy women. Methods Thirty-one healthy women [median age: 37.00 (34.00/40.00) years] were included in the study. The participants joined CT, arranged according to the recommendations of the American College of Sports Medicine, 3 days a week, an average of 40 min a day, for a total of 16 weeks. Before and after a CT, spine structure was assessed with the Spinal Mouse, trunk muscle endurance was assessed with the trunk flexion and extension endurance tests, and static balance was assessed with the Biodex Balance System. The Wilcoxon test was used to compare the pretest and posttest values within the group. The significance level (α) was set at 0.05. Results Following 16-week CT, the posture and mobility scores improved with large (1.06, 1.18, respectively) effect sizes (p = 0.002, p < 0.001, respectively). No positive effects on postural competency (p = 0.486), trunk flexor and extensor muscle endurance (p = 0.318, p = 0.572, respectively), and static balance eyes-open and eyes-closed (overall, anteroposterior, mediolateral) (p = 0.517, p = 0.173, p = 0.922, p = 0.925, p = 0.404, p = 0.196, respectively) were observed. Conclusion A 16-week CT effectively improved static posture and general mobility in healthy women, yet its observed lack of impact on postural competency, trunk muscle endurance, and balance suggests that future exercise interventions should integrate more targeted and specific components to achieve comprehensive physical fitness adaptations.
