本研究主要目的探討女子足球選手在不同場地規格中身體活動量之影響進行分析比較。以國立臺灣體育大學（臺中）女子足球隊共17位選手為受試對象，平均身高163.6±6.2公分，體重54.9±4.9公斤，年齡19.9±1.8歲，球齡9.9±1.8年。受試者分別在2v2、3v3、4v4、5v5不同場地規格中進行小型比賽測試，分析選手在比賽中運動強度、移動距離與觸球數等身體活動量的資料。以單因子重覆量數分析、獨立樣本t考驗等統計方法進行分析。所得結果顯示：女子足球選手在不同場地規格比賽中，以2v2的小型比賽心跳率最低，出現顯著差異，發現在3 v3與4v4場地規格中的比賽心跳率較接近11人制的比賽強度。5v5的場地規格中移動距離為91.2公尺/分，明顯少於其它場地規格，達到顯著差異。在觸球數方面，在2v2、3v3、4v4的小型比賽中，均多於5v5的場地規格，達到顯著差異，表示參與比賽的人數越多，觸球數越少。而不同運動能力的選手在運動強度、移動距離與觸球數方面相比較的結果，並無出現顯著差異。但是在觸球數方面，國家隊選手均多於非國家隊選手，表示運動能力較高的選手在移動的品質上能對球做出更有效的技術與戰術上的運用。

　　The purpose of this research was to compare and analyse the women soccer players physical activity under different small sided game. In National Taiwan Sport University (Taichung), the women soccer team has 17 players; the average height is 163.6±6.2 cm, body weight is 54.9±4.9 kg, age is 19.9±1.8 years old, and the number of years engaging in soccer game is 9.9±1.8 years. Competitors are in different field standards, which are 2v2, 3v3, 4v4 and 5v5. In addition, results have shown that the woman soccer players playing under different fields in 2v2 small competition has the lowest heart rate, in fact, when in 3v3 and 4v4, the heart rate is close to that in the official game . In field 5v5, the movement distance is 91.2m/min, which is less than other field standards. On the other hand, the numbers of time contacting the ball in 2v2, 3v3, 4v4 are more than in 5v5, which means the chances of contacting the ball will decrease when number of players increase. In conclusion, different experience of women soccer team players seem to not have much difference in their physical activity intensities, distances in movement and the number of times contacting the ball. However, players in the national team have better techniques in keeping the balls and have higher chances of contacting with the ball as to players not in the national team.
