Abstract

The purpose of this study was to determine the contribution of lower limb explosive power and waist flexibility to the performance of the flop-style high jump among students in the Department of Coaching Education, Faculty of Sports Science, Universitas Negeri Padang (FIK-UNP). This research was motivated by the observed low performance in the high jump, which is suspected to be influenced by insufficient explosive leg power and limited flexibility in the waist area. This study employed a correlational research design. The population consisted of 39 students enrolled in an advanced athletics course, comprising 37 male and 6 female students. A total of 37 participants were selected using purposive sampling. The instruments used were: the vertical jump test (using the Lewis formula) to measure lower limb explosive power, the bridge-up test to assess waist flexibility, and a standardized flop-style high jump test to evaluate high jump performance. Data were analyzed using single and multiple correlation techniques, followed by the calculation of the coefficient of determination (R² × 100%) to identify the contribution of each independent variable. The results showed that: (1) lower limb explosive power contributed 61.62% to high jump performance; (2) waist flexibility contributed 30.91%; and (3) both variables together contributed 69.22% to the students' flop-style high jump performance.

Abstract

This study aims to determine the effect of e-commerce hyperreality on the consumer behavior of private employees in Surabaya City and Dublin City. This study uses a quantitative correlational approach. Correlation research is a study that aims to see the form of relationship between two variables. The sample of this study consisted of 50 respondents, consisting of private employees in Surabaya City and five private worker informants in Dublin City, Ireland. The instrument in this study was a questionnaire consisting of 24 questions covering the identity of the respondents, the intensity of accessing e-commerce, interest in the image displayed by e-commerce, the type of goods purchased, and the amount of funds spent to buy goods on e-commerce. Data were analyzed using descriptive statistics to identify the characteristics of respondents, as well as Pearson correlation and Linearity Test to evaluate the relationship and influence of e-commerce hyperreality on consumer behavior. The results showed that private workers in Surabaya City used e-commerce more often than private workers in Dublin City. Private workers in Surabaya City have the reason that e-commerce prices are cheaper than those in offline stores. This study contributes to national and international literature by focusing on the influence of e-commerce on consumer behavior in the context of urban society. Practically, the data findings in this study can be used by the entire community to be wiser in using e-commerce, in the sense of buying goods based on needs, not because discounts and good-looking images tempt them.
