The Relationship Amongst Some Pulmonary Volumes, Anthropometric Measures and Cardio respiratory Efficiency of Professional Soccer Players in West Bank"

Abstract This study aimed to determine the level of some pulmonary volumes, anthropometric measures and cardio respiratory efficiency of professional soccer players in the West Bank, and to determine the relationship among these variables. In addition, the study aimed to determine the differences in these variables according to the playing position variable. To achieve these purposes, the study was conducted on a sample of (101) players of the professional clubs of Soccer in the West Bank , the mean age (23.56 years), the following measures were collected: anthropometric measures: (Age, height, body mass, chest circumferences , body mass index (BMI), body surface area (BSA), percent of body fat (BF%), fat free weight (FFM)), lung volumes: (Vital capacity (VC), Forced vital capacity (FVC), Forced Expiratory Volume at first second (FEV1) , Forced Expiratory Volume ratio at the first second to Forced Vital Capacity (FEV1/FVC%), Maximum Ventilatory Ventilation (MVV), Residual Volume (RV), Total Lung Capacity (TLC)), and to measure the efficiency of the cardio respiratory system the following variables were measured: (Maximum oxygen consumption (VO2max), blood pressure systolic and diastolic at rest and after Cooper test, heart rate at rest and after Cooper test, cardiac output at rest and after Cooper test, stroke volume(SV) at rest and after Cooper test. The study revealed that the level of anthropometric measurements (age, body mass, height, body mass index (BMI), body surface area (BSA), chest circumference at maximum inhalation, chest circumference at maximum exhalation, , percentage of body fat (BF%),body fat mass , fat-free mass (FFM were ordered respectively : (23.5 years, 70.28 kg, 1.75 m, 22.85 kg / m 2, 1.85 m 2, 92.9 cm, 8.65%, 6.14 kg, 64.13 kg). Also , the results of the study showed that the level of each of the following lung volumes: (vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), forced expiratory volume ratio at the first second to forced vital capacity (FEV1 /FVC%), maximum ventilatory ventilation (MVV), residual volume (RV), and the total lung capacity (TLC)),were respectively: (5.31 liters, 5.23 liters, 4.27l, 82%, 159.45 liters / min, 1.27 liters, 6.58 liters) The study also showed that the level of each of the (relative maximum oxygen consumption (VO2max), systolic blood pressure relieved (SBP), diastolic blood pressure during rest (DBP), pulse rate at rest (HR), the size of resting stroke volume (SV), cardiac output were respectively:(53.15 ml/k/min, 115.34 mm Hg, 75.49 mm Hg, 68.79 beats /min, 60.49 mL, 4.156 liters / min, 188 mm Hg, 88.6 mm Hg, 181 beats /min, 23.97 liters /min). The results showed that there were no statistically significant differences at the level of significance (α≤0.05) In pulmonary volume measurements depending on the variable of the position of play, While the results showed that there were statistically significant differences at the level of (α≤ 0.05) in the folloing anthropometric measurements (body mass, height, and body surface area (BSA), percentage of body fat (BF%), body fat mass), between the playing position variable, and in the favor of defense players compared to players of attack and center line. The results also showed that there were statistically significant differences between the different centers of play in the following measurements Cardio respiratory efficienty system: (Maximum oxygen consumption (VO2max), and systolic blood pressure at rest (SBP), and diastolic blood pressure at rest (DBP), and pulse rate comfort (HR), and the maximum pulse (HRmax), and the Stroke volume after the performance test Cooper (SVmax)) and in favor of center and attack compared to the defense line players, while the differences were not a function between the attack and center player. The study also showed that there were a significant relationship between volumes pulmonary (vital capacity (VC), forced vital capacity (FVC), expiratory forced in the first second (FEV1), maximum ventilatory ventilation (MVV), residual volume (RV), and total lung capacity (TLC)), with each of the measurements cardio respiratory efficiency system (maximum oxygen uptak (VO2max), and Cardiac output after testing Cooper (Qmax), and Stroke volume after testing Cooper (SVmax)). Also, the results of the study showed that there were a significant relationship between anthropometric measurements as follow: (height, body mass, body surface area (BSA), chest circumference at maximum inspiration, and fate-free mass (FFM)), with the lung volumes: (vital capacity (VC), vital capacity forced (FVC), forced expiratory in the first second (FEV1), maximum ventilatory ventilation (MVV), reserve volume (RV), and total lung capacity (TLC)). The results of regression revealed six predictive equations to predict lung volumes according to the body height variable. Based on the findings of the study the researcher recommended the following recommendations: - Taking advantage of the results of the current study as a criterion when measuring lung volumes and anthropometric measurements and the efficiency of the cardiorespiratory system . - Taking advantage of the equations that have been reached to predict the measure of lung volumes according to body height variable. Key words: Some Pulmonary Volumes, Anthropometric Measures, Cardio respiratory Efficiency , Soccer.
