Abstract

The purpose of this study was to analyze the effect of Countermovement Jump exercises and Depth Jump exercises on agility and leg muscle power, as well as analyze which exercises are more influential between Countermovement Jump exercises and Depth Jump exercises on agility and leg muscle power. The research method used in this research is quantitative with pseudo experimental method, with research design using pretest and posttest, group I Countermovement Jump, group II Depth Jump, and control group, with data analysis using ANOVA. Data retrieval process is done by testing limb muscle agility using side step test tool and limb muscle power test with jump md tool, during pretest and posttest. Then the data is analyzed. The target of this study was taken from the population of female students of sports training education Surabaya state university with 30 members, divided into 3 groups with each group of 10 people, this study was conducted for 8 weeks. Paired sample t test results, Agility and paired sample t test strength of limb muscles are known that the significance level of each variable is obtained sig 0.000 <0.05 so that there is a significant influence or difference between pretest and posttest of variable bound agility and limb muscle power. Anova test results on agility and muscle strength of the limbs, showed Agility, sig 0.018, power sig 0.000, so it can be concluded that there are significant differences in the results of agility and limb muscle power in three different groups, known sig <0.05. From the results of the post-hoc multiple comparations (LSD) test independent variables that have a significant influence on increasing dependent variables, it can be seen from the average different results that the Countermovement Jump and Depth Jump groups have their own advantages with the results of the data obtained, meaning that countermovement jump and depth jump exercises are able to improve biomotor agility and power, but both have different influences.
运动反动作跳跃和深度跳跃对提高敏捷性和腿部肌肉力量的影响
本研究的目的是分析反身跳练习和纵深跳练习对敏捷性和腿部肌肉力量的影响,并分析反身跳练习和纵深跳练习中哪个练习对敏捷性和腿部肌肉力量的影响更大。本研究采用的研究方法是采用伪实验方法定量,研究设计采用前测和后测,I组逆跳、II组纵深跳和对照组,数据分析采用方差分析。数据检索过程分别在前测和后测中使用侧步测试工具进行肢体肌肉敏捷性测试,使用跳跃测试工具进行肢体肌肉力量测试。然后对数据进行分析。本研究的研究对象取自泗水国立大学体育训练教育专业的女学生群体,共30人,分为3组,每组10人,研究时间为8周。配对样本t检验结果,四肢肌肉敏捷性和四肢肌肉力量的配对样本t检验结果已知,各变量的显著性水平为sig 0.000 <0.05,说明变量界敏捷性和四肢肌肉力量的前测和后测之间存在显著的影响或差异。四肢敏捷性和肌力的方差分析结果为agility, sig为0.018,power sig为0.000,可知三组之间敏捷性和肢体肌力的结果有显著性差异,已知sig <0.05。从事后多重比较(post-hoc multiple comparations, LSD)检验自变量对增加因变量有显著影响的结果来看,从平均不同的结果可以看出,根据所获得的数据结果,反跳组和纵深跳组各有优势,即反跳和纵深跳练习能够提高生物运动敏捷性和力量,但两者的影响不同。
