The purpose of this study is to investigate the effect of 16 weeks step-aerobic exercises and core exercises on left ventricular structure and function with some physiological parameters in sedentary women.MethodsTo achieve the purpose of this study, a total of 45 volunteers including (step-aerobic group (SAG, n = 25), core exercise group (CEG, n = 20) were selected as participants. Two different exercises were applied for 4 days a week, throughout 16 weeks, within 60 minutes for each exercise with the intensity of heart rate (HR) 60-70 percent. The HR was measured using a heart rate monitor for each subject. The physical, biochemical and echocardiographic characteristics of the women were measured before and after the exercise.ResultsDuring the exercise periods, there were a meaningful decrease in the body weight, BMI, value of waist region and hip circumference of the women in both intervention groups as well as in the values of HR, DBP, SBP (p < 0,05). In addition, serum homocysteine (Hcy) and high-sensitivity C-reactive protein (Hs-CRP) levels decreased and the VO2max and left ventricular diastolic end-diastolic dimension increased in both SAG and CEG (p < 0.05). The left ventricular diastolic functions of the SAG improved more than CEG. Left ventricular systolic ejection time and fractional shortening meaningfully improved in both SAG and CEG (p < 0.01).Conclusion16 weeks of step-aerobic and core exercise showed significant changes of inflammatory and lipid markers with cardiac dimensions and had favorable effects on both left ventricular systolic function. Left ventricular diastolic function had more improved in SAG than the CEG.

The aim of the study was to investigate the effect of aerobic and core strength exercises on forced vital capacity in sedentary women. A total of 40 healthy sedentary women (20 in an aerobic-step group and 20 in a core strength exercise group) with a mean age of 34.4±2.4 years participated voluntarily in this study. Two different exercises were applied to the women for 12 weeks, 4 days a week, at the intensity of 70% for 60 minutes. The women's resting heart rate (RHR), maximal oxygen consumption (VO2max), forced vital capacity (FVC), and forced air volume in the first second of forced expiration (FEV1) were measured before and after exercise. For statistical analysis, the Paired Samples-t test was used for intra-group evaluations, and the Independent Samples-t test was used for inter-group evaluations. After the exercise program, significant increases were found in the VO2max, FVC, and FEV1 values, while both groups experienced a decreased RHR (p<0.01). Since the aerobic and forced vital capacities of the sedentary women show a parallel increase as a result of the applied 12-week aerobic and core strength exercises, it can be said that the RHR, VO2maxmax, FEV, and FEV1 respiratory parameters also improved in a positive manner. For this reason, it may be advisable to apply both exercise types for the development of the aerobic and vital capacities of sedentary women.

This study has been designed to examine pre-service teachers' metaphorical perceptions of physical education and sports. In this study, phenomenology, one of the qualitative research designs, was used. The study group consists of 60 pre-service teachers studying at the Department of Physical Education and Sports Teaching at Şırnak University during the 2020-2021 academic year. Research data were obtained from the statements of students who were asked to complete the sentence "Physical Education and sports are like … for me because ... ". Research data were analysed using the content analysis method. The analysis of the data consists of stages including classification, elimination, category development, validity and reliability tests, and interpretation of the metaphors obtained in the study, respectively. Six categories were created in this study in which the metaphorical perceptions of pre-service teachers of the concept of physical education and sports were examined. Categories created for physical education and sports were healthy/quality life, life/lifestyle, freedom/entertainment, indispensable/sine qua non, source of peace/love, and development. As a result, it was determined that pre-service teachers have positive opinions about physical education and sports and have no negative judgment.
