Introduction: The aim of the study was to examine relationships between power of the lower limb and agility, speed, and change of direction (COD) deficit in professional female soccer players. Material and methods: Thirty-three elite Polish Extraliga league soccer players (aged 22 ±5 years; body height 166 ± 4 cm; body weight 58 ± 8 kg) performed the following fitness tests: lower limb muscle power (Leg Press, Half Squat, Counter Movement Jump), straight linear speed (SLS 20 m), and COD speed ( Zig-Zag test, COD deficit). Using the median value as a reference, the players were subdivided into two groups (n=17; n=16) according to their LP, HS 60% 1RM, CMJ (High values below median = stronger group and Low = weaker group ). Results: The COD deficit was calculated as the difference between the 20m speed and the Zig-Zag test. The stronger group was better than the weaker group in SLS 20m (p<0.05; ES=1.23; 0.83; 0.93), but in the Zig-Zag agility test, the difference in the results was not statistically significant (p>0.05; ES=0.48; 0.34; 0.34) and this affected the COD deficit, which was higher (p<0.05; ES=0.9; 0.73; 0.72). The most important finding was that the stronger group had a higher COD deficit and its improvement (reduction) occurs only if the results of the agility test are improved (through agility training) [Ydeficit All groups=0.10+0.87*20m - 0.83* Zig-Zag]. Increasing power (HS, LP) lead to the improvement in SLS p<0.05, not to COD abilities. Conclusion: This can be useful for coaches during agility training and to improve COD deficit in soccer players and women in general.

力量对女子足球运动员敏捷性、线速度和变向差的影响

简介:本研究的目的是研究职业女子足球运动员下肢力量与敏捷性、速度和方向改变 (COD) 缺陷之间的关系。材料与方法:33名波兰Extraliga联赛精英球员(年龄22±5岁;身高166±4cm;体重58±8kg)进行了以下体能测试:下肢肌肉力量(Leg Press,Half Squat) , 反向运动跳跃), 直线速度 (SLS 20 m), 和 COD 速度 (Zig-Zag 测试, COD 赤字)。使用中值作为参考,玩家根据他们的 LP、HS 60% 1RM、CMJ 被细分为两组(n=17;n=16)(低于中值的高值 = 更强组,低 = 弱组)。结果:COD 赤字计算为 20m 速度与 Zig-Zag 测试之间的差异。SLS 20m强组优于弱组(p<0.05;ES=1.23;0.83;0.93),但在Zig-Zag敏捷性测试中,结果差异无统计学意义(p>0.05;ES =0.48;0.34;0.34),这会影响 COD 不足,后者更高(p<0.05;ES=0.9;0.73;0.72)。最重要的发现是,更强的组有更高的 COD 赤字,并且只有在敏捷性测试的结果得到改善(通过敏捷性训练)时才会出现改善(减少)[Ydeficit All groups=0.10+0.87*20m - 0.83* Zig -Zag]。增加功率(HS,LP)导致 SLS p<0.05 的改善,而不是 COD 能力。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。但在 Zig-Zag 敏捷性测试中,结果差异无统计学意义(p>0.05;ES=0.48;0.34;0.34),这影响了 COD 不足,后者更高(p<0.05;ES=0.9; 0.73;0.72)。最重要的发现是,更强的组有更高的 COD 赤字,并且只有在敏捷性测试的结果得到改善(通过敏捷性训练)时才会出现改善(减少)[Ydeficit All groups=0.10+0.87*20m - 0.83* Zig -Zag]。增加功率(HS,LP)导致 SLS p<0.05 的改善,而不是 COD 能力。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。但在 Zig-Zag 敏捷性测试中,结果差异无统计学意义(p>0.05;ES=0.48;0.34;0.34),这影响了 COD 不足,后者更高(p<0.05;ES=0.9; 0.73;0.72)。最重要的发现是,更强的组有更高的 COD 赤字,并且只有在敏捷性测试的结果得到改善(通过敏捷性训练)时才会出现改善(减少)[Ydeficit All groups=0.10+0.87*20m - 0.83* Zig -Zag]。增加功率(HS,LP)导致 SLS p<0.05 的改善,而不是 COD 能力。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。更高(p<0.05;ES=0.9;0.73;0.72)。最重要的发现是更强的组有更高的 COD 赤字,并且只有在敏捷性测试的结果得到改善(通过敏捷性训练)时才会出现改善(减少)[Ydeficit All groups=0.10+0.87*20m - 0.83* Zig -Zag]。增加功率(HS,LP)导致 SLS p<0.05 的改善,而不是 COD 能力。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。更高(p<0.05;ES=0.9;0.73;0.72)。最重要的发现是更强的组有更高的 COD 赤字,并且只有在敏捷性测试的结果得到改善(通过敏捷性训练)时才会出现改善(减少)[Ydeficit All groups=0.10+0.87*20m - 0.83* Zig -Zag]。增加功率(HS,LP)导致 SLS p<0.05 的改善,而不是 COD 能力。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。LP)导致 SLS p<0.05 的改善,而不是 COD 能力的改善。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。LP)导致 SLS p<0.05 的改善,而不是 COD 能力的改善。结论:这对教练在敏捷性训练和改善足球运动员和女性的 COD 缺乏方面很有用。
