Brief Summary: RATIONALE Exercising regularly may lower the risk of breast cancer

PURPOSE This randomized clinical trial is studying how well exercise prevents breast cancer in healthy young women
Detailed Description: OBJECTIVES

Primary

Compare the changes in urine levels of a stable marker of oxidative stress F_2-isoprostanes in healthy young women who undergo exercise training during 4 menstrual cycles vs no exercise

Secondary

Assess the changes in other metabolic factors that explain the association between physical activity and breast cancer including

Estrogen metabolism estrone estradiol estriol 2-OHE_1 2-OHE_2 2-MeOHE_1 2-MeOHE_2 4-OHE_1 4-OHE_2 as well as ratios of these metabolites insulin-like growth factor IGF-1 as well as IGF-binding proteins-1 -2 and -3 insulin glucose body composition including body mass index lean mass and body fat DEXA scan

OUTLINE This is a randomized controlled study Participants are stratified according to baseline body fat percentage and age 18 to 24 years vs 25 to 30 years Participants are randomized to 1 of 2 intervention arms

Arm I Participants exercise for 30 minutes 5 times a week The intensity of exercise is increased every 4 weeks The exercise regimen continues for up to 4 menstrual cycles
Arm II Participants are observed for 4 menstrual cycles Participants in both arms undergo 24-hour collection of urine on days 7 8 and 9 of menstrual cycles 1 and 6 F_2-isoprostanes are measured via gas chromatography-mass spectrometry GCMS Estrogens are also measured by GCMS and include E_1 E_2 E_3 2-OHE_1 2-OHE_2 4-OHE_1 4-OHE_2 2-MeE_1 2-MeE_2 4-MeE_1 4-MeE_2 and 16OHE_1

Participants undergo blood collection body mass measurement by dual-energy x-ray absorptiometry and a fitness assessment twice during the 6-month study

PROJECTED ACCRUAL A total of 400 participants will be accrued
