ABSTRACT

Aim:

Vitamin D deficiency is very common in general population and has potentially harmful effect on musculoskeletal system. We aimed to show the effect of vitamin D deficiency on the muscle performance by using isokinetic test.

Meterial and Methods:

This study includes 12 women with vitamin D deficiency for patient group and 12 healthy women for control group. We compared knee muscles performance of these two groups by using isokinetic test.

Results:

The mean age was 40.71 (26-57) years in patients and 41.43 (28-58) years in healthy group. There was no statistical difference between two groups at knee flexion and extension pick-torque values in 60°/s velocity and fatigue index in 180°/s velocity (respectively, p1=0.86, p2=0.12, p3=0.42).

Conclusion:

Vitamin D deficiency has no effect on muscle performance. Further invastigations that evaluating larger populations are needed. (Turkish Journal of Osteoporosis 2013;19: 17-9)
