Clinical Sciences Research Proposal- The Effect of Physical Exercise on PCOS Overweight Female Adolescents


Brief description of study

The Poly Cystic Ovary Syndrome (PCOS), is one of the most common reasons for subfertility, oligomenorrhea and amenorrhea. With the occurrence of 6-20% of the general adult women population. One of the main criteria of this syndrome is a hyper androgenic state.

More than 50% of women who have PCOS are overweight. In the teenage population, PCOS is common in 5-10% of teenage girls. A recent research has shown that elite athlete teenage girls have higher serum androgen levels, especially in anaerobic types of sport.

The purpose of this experiment is to examine the reaction of teenage PCOS overweight girls towards anaerobic exercise. To determine if their hyperandrogenic state is more adapted to excel in anaerobic exercise compared to teenage overweight girls without PCOS.

Detailed Study Description

30 teenage and young adult females, aged 10-25 years old. The minimum hormonal age for inclusion is menarche. Overweight- with a Body Mass Index (BMI) percentage above 85%, divided into 2 groups: 15 girls with diagnosed PCOS, and 15 girls without diagnosed PCOS, without any other medical comorbidities. Followed at the pediatric endocrinology unit.

The 2 groups would participate in 2 anaerobic tests to evaluate their performances. The data received will be used to evaluate their anaerobic attributes, and for comparison between the 2 groups to determine any differences.

The participants will be asked to refrain from any form of physical exercise during the previous day.

After explanation to the patient and his parent and obtaining an informed consent, the participants will start the tests.

The first test is the Repeated Sprint Test: The participant will run a distance of 40 meters, for 6 repetitions. The optimal running time will be calculated, total running time and the Performance Decrement of the run will be calculated.

After that, there will be a 1-1.5 hours resting phase. The second test is the "Wingate Test"- the participants will be instructed to pedal at a maximal pace for 30 seconds on an ergometric bicycle against a resistance adjusted according to their BMI. The Peak Anaerobic Power, the Mean Anaerobic Power and the Fatigue Index will be calculated.
