Obesity is a strong risk factor for the development and progression of sleep apnea. Responses to exercise by patients with obstructive sleep apnea syndrome (OSAS) are clinically relevant to reducing body weight and cardiovascular risk factors. This study aimed to clarify the aerobic and anaerobic exercise capacities and their possible relationships with other findings in patients with OSAS. Forty patients (30 males, 10 females) and 40 controls (30 males, 10 females) were enrolled in this study. Questionnaires (excessive daytime sleepiness, daytime tiredness, morning headache, waking unrefreshed, and imbalance), overnight polysomnography, indirect laryngoscopy, and aerobic and anaerobic exercise tests were performed. Triceps, subscapular, abdomen, and thigh skinfold thicknesses were measured. Subcutaneous abdominal fat (abdomen skinfold) was significantly higher in OSAS patients than in controls. Maximal anaerobic power and anaerobic capacity were not different significantly between the patients and controls. We found that aerobic capacity was significantly lower in OSAS patients than in controls. Aerobic capacity was negatively correlated with upper-body subcutaneous fat (triceps and subscapular skinfolds) but not correlated with subcutaneous abdominal fat in OSAS patients. In multivariate analyses using all patients, the apnea-hypopnea index remained a significant independent predictor of aerobic capacity after controlling for a variety of potential confounders including body mass index. Our data confirm that central obesity (subcutaneous abdominal fat) is prominent in patients with OSAS. Our results suggest that lower aerobic exercise capacity in patients with OSAS might be due to daily physical activity that is restricted by OSA itself. This study also suggests that the degree of subcutaneous abdominal fat cannot be used for predicting aerobic capacity level. We think that upper-body subcutaneous fat might be suitable for determining the physical fitness of patients with OSAS.

Objective Obstructive Sleep Apnea Syndrome (OSAS) is a common sleep-related breathing disorder. Associations among Apnea-Hypopnea Index (AHI), Resting Metabolic Rate (RMR), body habitus differences, and otorhinolaryngologic abnormality may clarify the characteristics of patients with OSAS. In order to test this hypothesis, we aimed to compare the RMR, Modified Mallampati Scores (MMS), anthropometric measurements and body composition of male OSAS patients with simple snorers and to investigate the association among these parameters. Methods MMS were calculated, overnight polysomnography was performed, body mass index, neck, shoulder, chest, waist, hip and abdomen circumferences, body fat amount and ratio, lean body weight, body water amount and RMR were measured for all of the patients. Patients Ninety-eight male patients with suspected OSAS were included in the study. Results Fifty-one patients were diagnosed as OSAS and 47 patients were diagnosed as simple snorers. RMR, total body water, neck, shoulder and chest circumferences were significantly higher in OSAS patients than the simple snorers. The majority of the simple snorers was seen to have a MMS of stage 2 whereas OSAS patients had MMS of stages 3 and 4. AHI was significantly correlated with neck, shoulder, chest circumferences, total body water amount, MMS and RMR. Chest girth was found as the most important single predictor of sleep apnea in multivariate analysis. Conclusion We suggest that the increased RMR and chest circumference might have occured due to the condition resulting from the elevated AHI in patients with OSAS. Mallampati score should be routinely evaluated in OSAS patients.

These results suggest that the upper body anthropometry and respiratory function relations might have impaired in patients with PCOS. We think that this situation might support the increased tendency for poor health status in patients with PCOS.

The aim of this study were to investigate the physical activity levels in Afyon Kocatepe University Medical Faculty students and to determine the relationships between the physical activity and the parameters of grade, age, gender, and body mass index (BMI). A questionnaire, short form of the International Physical Activity Questionnaire, was applied to a total of 256 (118 female, 138 male) volunteer students for vigorous and moderate physical activity, walking and sitting times, grade, age, gender, height and weight of the participants.Questionnaire findings were grouped on the basis of student grades. BMI was calculated with formula using height and weight. Total physical activity times of participants were calculated and then classified as low, moderate and high.
