Abstract
Objective: Leptin a protein with a cytokine-like helical structure and molecular weight of 16 KDa, regulates the body weight and homeostasis of the energy in the body. However, changes in leptin and its relation with the caloric intake after adaptation with aerobic exercise are unknown. The aim of this study was to investigate the effects of two mounts of aerobic trainings on caloric intake and leptin and insulin plasma level in healthy females.
Materials and Methods: Twenty-three female (average age 19.58 ± 2.12 yr, BMI 21.63 ± 2.7 kg/m² and Weight 64.86 ± 6.46 kg) were randomly assigned to experimental and control groups. The subjects of the experimental group performed aerobic trainings with the maximal heart rate intensity of 60-85% three times per week and for eight weeks. 72 hours prior to and post the eight- week aerobic trainings, the subjects performed exhausting exercise and four stages of blood sampling were taken in a non-fasted state before and after the exhausting exercise.
Results: The findings of this study indicated that aerobic trainings had no significant, meaningful effect on plasmas leptin and insulin concentration and caloric intake at rest state after exhausting exercise while there were significant, meaningful decreases of glucose amounts after exhausting exercise.
Conclusion: Weight no change and also the loss of the remarkable negative equation are of possible reasons for no change in leptin and caloric intake after aerobic trainings. For change in leptin, it seems that the volume and intensity of trainings must be high .This index is highly stable.
