Abstract

Background and Aim: Poly cystic ovarian syndrome and thyroid disorders are the commonest endocrine disorders. Hypothyroid can lead to polycystic morphology of the ovaries and is therefore commonest finding in PCOS patients. Disturbances of the autonomic nervous system play a crucial role in the pathogenesis and clinical course of many diseases. Cardiorespiratory Fitness (CRF) is an objective measure of habitual physical activity and also a useful diagnostic and prognostic health indicator for patients in clinical settings. Many studies have suggested that CRF has an impact on the autonomic control of Heart Rate (HR). The aim of the study was to find out correlation between CRF and Heart Rate Recovery (HRR) in PCOS and PCOS with hypothyroidism patients. Methods: Newly medically diagnosed not on medications total 43 subjects were recruited, subjects were divided into group A (PCOS; n=33) and group B (PCOS with hypothyroidism; n=10). Anthropometric measurements were taken, CRF was assessed by 3 min YMCA submaximal step test and autonomic function tests for assessing parasympathetic function such as heart rate response to immediate standing (IS) (30:15) and Standing to Lying ratio (S:L) were employed, Electrocardiogram (ECG) machine (RMS-Vesta 301i electrocardiograph) was used for assessing parasympathetic function then measurements was taken according to the respective scoring procedures. Results: Negative correlation was observed in S:L test in PCOS group and IS test in PCOS with hypothyroidism group and positive correlation was observed in IS test in PCOS group and S:L test in PCOS with hypothyroidism group. No significance was found between HRR and CRF in PCOS as well as PCOS with hypothyroidism in our studied population. Conclusion: CRF was not a predictor of HRR in studied population, thus we conclude that CRF has no short-term effect on HRR in PCOS and PCOS with hypothyroid patients.
