ABSTRACT Gungor H, Comparison of Respiratory Function and Physical Fitness Parameters of Professional Basketball Players with Sedentary Controls, Hacettepe University, Graduate School of Health Sciences, Master Thesis in Cardiopulmonary Rehabilitation, Ankara, 2019. As a result of regular exercises, many adaptations occur in the body at the tissue level, circulatory-respiratory systems and body composition. The capacity to use aerobic and anaerobic energy systems increases. For this reason, regular sports individuals in many health-related and sports-related parameters to prevent sedentary. The increased metabolic demands of the respiratory muscles during exercise activate the metaboreflex mechanism, reducing blood flow to the locomotor muscles and reducing exercise performance. With the increase in respiratory muscle performance, activation of the metaboreflex mechanism can be postponed and longer exercise can be done with less fatigue. Therefore, respiratory muscle functions are very important for effective and efficient blood flow distribution. The aim of the study was to compare the professional basketball players and sedentary controls in terms of respiratory muscle strength, respiratory muscle endurance and physical fitness parameters and to investigate the relationship between respiratory function and physical fitness parameters in basketball players. 21 professional female basketball players and 21 sedentary women of similar age were included in the study. The characteristics of the subjects such as age and sports age were recorded. Mouth pressure measurement (maximal inspiratory pressure-MIP and maximal expiratory pressure-MEP), respiratory muscle endurance test, 20 m shuttle run test, T-Drill test, 20 m speed test and hand reaction speed test were used in the evaluation of the individuals. As a result of the study, basketball players' MIP, MEP, respiratory muscle endurance, shuttle run distance, VO2max were significantly higher than sedentary individuals (p <0.05). T-Drill test, 20 m speed test and hand reaction speed test results were found to be significantly better than sedentaries (p <0.05). Basketball players' body fat ratio measurements were negatively correlated with 20 m speed test (r= -0.648 p = 0.002) and T-Drill test (r = -0.480 p = 0.028). There was a statistically significant positive correlation between fat free mass (FFM) values and % MIP values (r = 0.456 p = 0.038) . The basketball players' respiratory muscle endurance and shuttle run distance (r = 0.811 p <0.001) and VO2max values (r = 0.560 p=0.008) were correlated. MIP values and shuttle run distance (r = 0.518 p = 0.016) and VO2max values (r = 0.560 p = 0.008) were positively correlated. MIP values were negatively correlated with hand reaction speed test (r = -0.489 p = 0.024) and T-Drill test (r = -0.465 p = 0.034). As a result, it was seen that regular sporting activities positively improved pulmonary functions and physical fitness parameters. In addition, basketball players with better pulmonary functions were found to be more successful in physical fitness parameters. Therefore, it may be recommended to include respiratory muscle training in the athletes' training programs. Key Words: Basketball, respiratory function, physicall fitness.
