Brief Summary

The effects of a 16-week exercise training program on insulin resistance and adiposity in overweight/obese women with Polycystic ovary syndrome (PCOS).

Detailed Description

Young, overweight/obese women with PCOS along with age and BMI-matched healthy controls without PCOS will be enrolled in this study. Participants will have assessments of body composition (by DEXA), visceral and ectopic fat (by MR), ovarian parameters (follicle size and number, by MRI) insulin sensitivity (by euglycemic hyperinsulinemic clamp), interstitial lipolysis (by microdialysis), whole body lipolysis and glycolysis (by stable isotopes), aerobic fitness (by VO2max test) and a fat biopsy performed across two clinic visits (1 outpatient visit, and 1 overnight stay). Participants in the control group will undergo these assessments once only, whereas participants in the PCOS Group will have these assessments twice, once at baseline and once following a 16 week supervised aerobic exercise program. Throughout the exercise program body weight will be measured weekly and menstrual cycle frequency will be documented on a calendar. Additionally, vital signs, weight, waist and hip circumferences will be measured and a fasting blood sample collected every 4 weeks.

Overweight/obese women with PCOS

10 overweight/obese women with polycystic ovary syndrome

Group Type: EXPERIMENTAL

16-week exercise training program

Intervention Type: OTHER

The primary objective of the study is to investigate the effects of a 16-week exercise training program on insulin resistance and adiposity in overweight/obese women with PCOS.

Control Group without PCOS

Intervention Type: OTHER

A group of overweight/obese women without PCOS will be enrolled as a control group and will be studied only once at baseline to allow for comparisons between the two study populations.

Eligibility Criteria

Inclusion Criteria

• Women between the ages of 18-30, inclusive.
• BMI greater than or equal to 25.
• Sedentary lifestyle - not currently exercising more than 60 minutes per week.
• A medical diagnosis of polycystic ovary syndrome. The diagnosis will be compared with the most recent international criteria1. Together with irregular menses (fewer than 6 cycles per year), participants must also have at least one of the following characteristics;

1. presence of polycystic ovaries on transvaginal ultrasound, >10 cysts, 2-8 mm in diameter (ultrasound will not be done in this study however; ultrasound reports will be used if available) and/or

2. clinical manifestations (hirsutism) examined by the PI at the screening visit or biochemical evidence (elevated testosterone or free androgen index) of hyperandrogenism, determined by fasting blood sample collected during the screening visit.

• Women enrolling for the non-PCOS control group are required to have regular menstrual cycles (one cycle per month).

Exclusion Criteria

• Individuals with a history of cardiovascular disease or an elevated blood pressure above 160/90 mmHg.
• Individuals with a history of Diabetes (Type 1 or Type 2).
• Individuals with a history of Kidney, Liver or Heart disease.
• Individuals with untreated thyroid disease.
• Individuals who smoke.
• Individuals who exercise more than 60 minutes per week.
• Individuals who use medications including contraceptives (medications used to treat thyroid disease are permitted).
• Individuals with alcoholism or other substance abuse.
• Individuals who are pregnant or lactating (breast feeding).
• Individuals who become pregnant throughout the study will be excluded.
• Individuals who are trying to become pregnant.
• Control subjects will be excluded if they have irregular menses (fewer than 1 cycle per month).
• Unable to complete approximately 60 minutes of medium intensity exercise per day (5 days per week) at the Pennington Health and Fitness Center (PCOS Group Only).

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 30 Years
• Eligible Sex: FEMALE
