Effect of Exercise on Vitamin d in Obese

Effect of Exercise-induced Lipolysis on Vitamin D Status in Obese Children

The aim of the current study was to investigate the effect of exercise-induced lipolysis on vitamin D status in obese children. Two types of exercises that have different effects on lipolysis were used. Lipolysis was assessed via monitoring the level of plasma level of the free fatty acids and glycerol. Vitamin D was assessed through 25 (OH)D plasma levels.

vitamin D status was monitored through 25 (OH)D levels, and the lipolysis status via the plasma level of the free fatty acids and glycerol immediately after the exercise. All subjects who participated in the study were under supervision for controlling the fat contents and vitamin D in their food for one week prior to the exercise. the subjects fasted eight hours before the exercise. All the exercises were performed between 9 am and 11 am.

• 25(OH) D was ranged from 10-20ng/ml
