比較不同位置女子足球員的無氧能力

Anaerobic Ability of Female Soccer Players According to Playing Position

足球運動具有間歇活動的特質，表示球員需要有氧與無氧機能以支持各種不同速率的活動。許多關於不同位置球員能量供應系統方面的研究，多數在探討他們有氧能力的差異，無氧方面的資料比較缺乏。因此，本研究目的在比較不同位置女子足球員間的無氧能力。受試者共23位年齡17－19歲正在訓練期的優秀大專女子足球員（前鋒5位、中場7位、後衛9位及守門員2位），身高163.1±4.5公分，體重56.0±6.2公斤，球齡6.9±2.0年。在非乳酸性無氧能力測驗方面，僅守門員的馬加里亞－卡門動力值（111.7±10.8公斤公尺／秒）顯著（p＜0.05）高於中場（89.1±11.1公斤公尺／秒），但與前鋒（97.6±7.1公斤公尺／秒）和後衛（94.4±9.9公斤公尺／秒）之間，並未達顯著差異（p＞0.05）。此外，在乳酸性無氧能力測驗方面，各位置間的800公尺跑後血乳酸變化值；前鋒（13.4±1.7mmol／L）、中場（11.0±2.4mmol／L）、後衛（11.7±1.9mmol／L）以及守門員（10.7±1.3mmol／L）之間，都未達顯著差異水準（p＞0.05）。本研究資料顯示，球場上的角色位置，似乎可反映出女子足球員非乳酸性或乳酸性的無氧能力，以及不同的生理需求。The sport of soccer is take on a peculiarity of interval movement, it represents that the players need aerobic and anaerobic functions to be with all sorts of activities of speeds. There are many studies of energy regarding players of different positions almost search for diversity in their aerobic ability, and no such data is available in anaerobic power. The purpose of this study was to examine the different positions of anaerobic energy in female soccer players. Twenty-three 17 to 19 years old intercollegiate level female players (forward 5, midfielder 7, defender 9 and goalkeeper 2) that the height, weight, and playing experience were 163.1 ± 4.5 cm, 56.0 ± 6.2 kg, and 6.9 ± 2.0 y respectively. Power value of Margaria-Kalamen of the goalkeepers (111.7 ± 10.8 kgm/sec) was significantly (p<0.05) higher than the midfielders (89.1 ± 11.1 kgm/sec). The goalkeepers had higher phosphagen system, may be due to the training of pounce the ball often. Besides, Lactic acid were taken pre- and post 800-m run of the forwards (13.4 ± 1.7 mmol/L), midfielders (11.0 ± 2.4 mmol/L), defenders (11.7 ± 1.9 mmol/L) and goalkeepers (10.7 ± 1.3 mmol/L) were no significantly differences. The results of this study indicate that the phosphagen and lactate system of female soccer players maybe accounts for their different roles played in games as well as the physiological demand of the corresponding positions.
