Different coaching methods are often used to improve performance. This study compared the effectiveness of 2 methodologies for speed and agility conditioning for random, intermittent, and dynamic activity sports (e.g., soccer, tennis, hockey, basketball, rugby, and netball) and the necessity for specialized coaching equipment. Two groups were delivered either a programmed method (PC) or a random method (RC) of conditioning with a third group receiving no conditioning (NC). PC participants used the speed, agility, quickness (SAQ) conditioning method, and RC participants played supervised small-sided soccer games. PC was also subdivided into 2 groups where participants either used specialized SAQ equipment or no equipment. A total of 46 (25 males and 21 females) untrained participants received (mean +/- SD) 12.2 +/- 2.1 hours of physical conditioning over 6 weeks between a battery of speed and agility parameter field tests. Two-way analysis of variance results indicated that both conditioning groups showed a significant decrease in body mass and body mass index, although PC achieved significantly greater improvements on acceleration, deceleration, leg power, dynamic balance, and the overall summation of % increases when compared to RC and NC (p < 0.05). PC in the form of SAQ exercises appears to be a superior method for improving speed and agility parameters; however, this study found that specialized SAQ equipment was not a requirement to observe significant improvements. Further research is required to establish whether these benefits transfer to sport-specific tasks as well as to the underlying mechanisms resulting in improved performance.
不同的训练方法常被用于提高运动表现。本研究比较了两种方法对随机、间歇性和动态活动类运动(如足球、网球、曲棍球、篮球、橄榄球和无挡板篮球)的速度和敏捷性训练效果,以及对专门训练设备的需求。两组分别接受程序化训练方法(PC)或随机训练方法(RC),第三组不接受任何训练(NC)。PC组参与者采用速度、敏捷性、快速性(SAQ)训练方法,RC组参与者进行有监督的小型足球比赛。PC组又分为两组,一组使用专门的SAQ设备,另一组不使用设备。共有46名(25名男性和21名女性)未经训练的参与者在一系列速度和敏捷性参数现场测试之间的6周内接受了(平均±标准差)12.2±2.1小时的体能训练。双向方差分析结果表明,两个训练组的体重和体重指数均显著下降,不过与RC组和NC组相比,PC组在加速、减速、腿部力量、动态平衡以及百分比增加的总体总和方面取得了显著更大的改善(p<0.05)。SAQ练习形式的PC似乎是提高速度和敏捷性参数的更优方法;然而,本研究发现,观察到显著改善并不需要专门的SAQ设备。需要进一步研究以确定这些益处是否能转化为特定运动任务,以及导致运动表现改善的潜在机制。
