Maximum Oxygen Uptake ,Anaerobic Power, Resting Metabolic Rate and Body Composition among Female Soccer Players in West Bank

Abstract The purpose of this study was to determine the Maximum oxygen uptake (Vo2max), Anaerobic Power(AP), Resting Metabolic Rate(RMR) and Body Composition (BC) among Female Soccer Players in the West Bank. And to determine the relationship amongst variables, as well as to identify differences in these variables according to the playing position . The sample of the study was consisted of (55) players, and the means of age, height, and body mass were respectively: (15.58 years old, 1.59 meters, 59.16 kg). The study adopted the following tests on the study sample that include: Queen's University Step Test(QUST) to measure the maximum oxygen consumption, Lewis equation and an 40 meters-sprint test to measure Anaerobic Power, Meflin equation to measure RMR, and the Beaulieu equation to measure body composition. After collecting and processing data (SPSS)was conducted, and the study reached following results: - The means of maximum oxygen consumption, 40 meters sprint, vertical jump, long jump, Lewis equation, Resting Metabolic Rate ,body mass index, percentage of body fat, fat body mass, and body fat free mass were respectively: (36.08 ml . kg / min), (7.55 seconds), (33.69 cm), (166.6 cm), (97.89 kg. m / s), (1352.5 kcal / day). (23.15 kg) , (26.78%), (15.89 kg), and (43.26 kg). - There was no significant relationship between maximum oxygen consumption and the rest of the variables under study. There was a set of relationships between variables, and the most interesting of these relations was between the Anaerobic Power and body fat free mass (0.68), and between (RMR)) and body mass (0.91), and between body mass and body fat free mass (0.81). - There were a significant differences at the significance level (0.05) in maximum oxygen consumption due to playing position in favor to midfield players. Where the highest average of the maximum oxygen consumption was for the midfield players (37.45 ml / kg / min), and the lowest value was for goal keepers (34.41 mL / kg / min). - There were a significant differences at the significance level (0.05) in the Anaerobic Power (Lewis formula) according to the playing position in favor of goal keepers; the highest value of the Anaerobic Power for the goalkeepers (119.99) kg. M / s and lowest was for midfield players (91.87) kg. M / s. - There were a significant differences at the significance level (0.05) in the 40 meters sprint test due to playing position in favor to attack players , the best mean was for attack players (7.139) seconds and the lowest mean was for goalkeepers (8.065) seconds. - There were a significant differences at the significance level (0.05) in vertical jump due to playing position in favor to goalkeepers, where the best mean was for goalkeepers (37.63 cm) , and the lowest mean was for midfield players (31.69 cm) . - There were a significant differences at the significance level (0.05) in long distance jump due to playing position in favor to attack players , the best mean was for goalkeepers (178.13 cm) ,and lowest mean was for midfield players (158.85 cm). - There were a significant differences at the significance level (0.05) in RMR due to playing position in favor to goalkeepers, where the highest was (1422.91 kcal / day) ; the lowest mean was for Defense players (1335.47 kcal / day). - There were no significant differences at the significance level (0.05) in body composition due to the playing position variable. Based on the findings of the study, the researcher made the following recommendations: -Coaches should Pay attention to the parameters in the physiological measurements of the variables under study because of their important role in the preparation of training programs needed to attain international standards in soccer. - The need to provide some important information in the records of each player of the physical and physiological measurements to facilitate researchers to conduct scientific research for improving the level of this sport in Palestine.
