Pengaruh Olahraga Teratur Terhadap Kadar Estrogen Adiposa dan Estrogen Serum pada Tikus Sprague dawley yang Dilakukan Ovariektomi

Eka Bebasari


Menopause has some effects on women’s health. Exercise is one alternative to resolve menopausal complaints.
Regular exercise can increase serum estrogen level in postmenopausal women. This increase is believed to occur
through increased aromatization of androgen in extragonadal tissue especially adipose tissue in postmenopausal women.
The purpose of this study is to explore estrogen levels in adipose tissue and serum due to regular exercise in
ovariectomized rats. A post-test only control group design was performed in this study. Ten female Sprague dawley
rats were used throughout the study and randomly selected. Rats were ovariectomized and divided into two groups:
five rats in treated group and five rats in control group. Treatment groups get treadmill exercise for 8 weeks. Furthermore,
rats blood were taken for examination of serum estrogen level, rats were killed and subcutaneous abdominal adipose
tissue were removed for examination of estrogen level in adipose tissue. Statistical analysis was performed with
independent t test. Estrogen level in adipose tissue was higher in the treatment group but not statistically significant (p
> 0,05). Higher serum estrogen levels in the control group but not statistically significant (p > 0,05). Extragonadal
aromatization has occurred in adipose tissue of ovariectomized rats with regular exercise.
