Methods	Study design: randomised controlled trial Duration: 3 months Power calculation: unclear
Participants	Number of participants: 25 in control, 25 in intervention PCOS definition: women with a confirmed diagnosis of PCOS, definitions unclear Baseline characteristics (mean ± SD), intervention versus controls: unclear Inclusion criteria: Quote: "Participants have body mass index = 25 kg/m2; All Participants treat with same dose of oral contraceptives pill and spirinolactone; All Participants have menstrual pattern as oligomenorrhea (irregular bleeding episodes with intervals occur more than 35 days); All Participants have suffered some degree of hirsutism." Exclusion criteria: Quote: "1‐ Use of any drug other than the standard drug for the treatment of polycystic ovary syndrome, which is the same for everyone. (Including drugs to treat infertility, diabetes, hormonal drugs, reduce appetite and etc); 2‐ Smoking; 3‐ Being in pregnancy and lactation period or pregnancy decision; 4‐ Having cardiovascular, renal, liver, respiratory diseases, diabetes, uncontrolled hypertension, malignancy or any other acute or chronic disease; 5‐ Prohibition of the exercise due to illness or any other cause according to physician order; 6‐ Participating in regular exercise before the start of the study; 7‐ Having a separate diet programs before the start of the study." Groups comparable at study commencement: unclear Participants actively seeking pregnancy at study commencement: not stated
Interventions	Comparison: a) Intervention: Quote: "Diet plan: at the beginning of study a check list prepared for each individual and weekly regimen recommended separately based on feeding patterns and individual facilities. The method of regimen calculation based on total energy for each individual (TEE). We set the countable energy for reducing weight 1000 grams per week. Reduced the amount of energy and some energy into the physical activity to lose weight fraction are obtained. The combination of energy, including 40% carbohydrate, 30% fat (less than 8% saturated fatty acids was) and 30% protein is high physiological value. Fitness program: exercise sessions that included 24 meeting which duration per session was variable according to the program. For improving aerobic energy system and strengthen cardiovascular system a series exercises (slow jogging) will be used. At the beginning of the first practice sessions will be used slow intensity aerobic exercise. The first training sessions with 5 minutes of times, and 50 percent of maximum heart rate of cholera in the form alternating between resting half the time repeating the exercise. In each session we were trying to follow the principle of overload for improving cardiovascular efficiency. In higher stages (after the fifth session) of the repetition of exercises with some 60 percent of maximum heart rate is achieved. Of the ninth session, training intensity reaches to 70 percent of maximum heart rate and in last sessions with 80 percent maximum heart rate do their exercise. In each session, subjects in the first 10 minutes to warm the body and also the final 10 minutes of cooling down exercises and return to the initial state." b) Control: not stated Compliance with intervention: not stated
