Introduction: Vitamin D and albumin are important biochemical markers in diabetes management. This study examined the effect of moderate-intensity aerobic exercise on serum vitamin D and albumin levels in women with type 2 diabetes in Yazd, Iran.
Materials and Methods: In this experimental study with a pretest-posttest control design, 30 women aged 40–50 years were randomly assigned to an exercise or control group (15 each). The exercise group performed treadmill aerobic exercise at 35–75% of maximum heart rate, three times per week for eight weeks. Serum vitamin D and albumin levels were measured before and after the intervention. Paired and independent t-tests were used for analysis.
Results: Post-intervention, vitamin D levels slightly increased in the exercise group, but changes were not statistically significant (p = 0.155), nor were between-group differences (p = 0.190). Albumin levels showed a significant within-group increase in the exercise group (p = 0.009), while between-group differences remained non-significant (p = 0.273).
Conclusion: Eight weeks of moderate-intensity aerobic exercise significantly improved albumin levels within the exercise group, but vitamin D changes and between-group differences were not significant. These findings suggest that longer-duration interventions or combination with dietary strategies may be necessary to elicit significant changes in biochemical markers in women with type 2 diabetes.
