The aims of this study were to evaluate the reliability of a modified agility T-test (MAT) and to examine its relationship to the free countermovement jump (FCMJ) and the 10-m straight sprint (10mSS). In this new version, we preserved the same nature of displacement of the T-test but we reduced the total distance to cover. A total of 86 subjects (34 women: age = 22.6 +/- 1.4 years; weight = 63.7 +/- 10.2 kg; height = 1.65 +/- 0.05 m; body mass index = 23.3 +/- 3.3 kg x m(-2) and 52 men: age = 22.4 +/- 1.5 years; weight = 68.7 +/- 8.0 kg; height = 1.77 +/- 0.06 m; body mass index = 22.0 +/- 2.0 kg x m(-2)) performed MAT, T-test, FCMJ, and 10mSS. Our results showed no difference between test-retest MAT scores. Intraclass reliability of the MAT was greater than 0.90 across the trials (0.92 and 0.95 for women and men, respectively). The mean difference (bias) +/- the 95% limits of agreement was 0.03 +/- 0.37 seconds for women and 0.03 +/- 0.33 seconds for men. MAT was correlated to the T-test (r = 0.79, p < 0.001 and r = 0.75, p < 0.001 for women and men, respectively). Significant correlations were found between both MAT and FCMJ, and MAT and 10mSS for women (r = -0.47, p < 0.01 and r = 0.34, p < 0.05, respectively). No significant correlations were found between MAT and all other tests for men. These results indicate that MAT is a reliable test to assess agility. The weak relationship between MAT and strength and straight speed suggests that agility requires other determinants of performance as coordination. Considering that field sports generally include sprints with change direction over short distance, MAT seems to be more specific than the T-test when assessing agility.
本研究的目的是评估改良敏捷T测试（MAT）的可靠性，并检验其与自由反向纵跳（FCMJ）和10米直线冲刺（10mSS）之间的关系。在这个新版本中，我们保留了T测试相同的位移性质，但缩短了总移动距离。共有86名受试者（34名女性：年龄 = 22.6±1.4岁；体重 = 63.7±10.2千克；身高 = 1.65±0.05米；体重指数 = 23.3±3.3千克/米²；以及52名男性：年龄 = 22.4±1.5岁；体重 = 68.7±8.0千克；身高 = 1.77±0.06米；体重指数 = 22.0±2.0千克/米²）进行了MAT、T测试、FCMJ和10mSS测试。我们的结果显示MAT重测分数之间没有差异。MAT的组内可靠性在各试验中均大于0.90（女性和男性分别为0.92和0.95）。女性的平均差异（偏差）±95%一致性界限为0.03±0.37秒，男性为0.03±0.33秒。MAT与T测试相关（女性和男性的r分别为0.79，p < 0.001和r = 0.75，p < 0.001）。女性的MAT与FCMJ以及MAT与10mSS之间均存在显著相关性（分别为r = -0.47，p < 0.01和r = 0.34，p < 0.05）。男性的MAT与所有其他测试之间未发现显著相关性。这些结果表明MAT是评估敏捷性的可靠测试。MAT与力量和直线速度之间的弱相关性表明，敏捷性需要其他表现决定因素，如协调性。考虑到田径运动通常包括短距离变向冲刺，在评估敏捷性时，MAT似乎比T测试更具特异性。
