Abstract

Background and Study Aim. Boxing requires an optimal balance between body weight and reaction speed. Body Mass Index (BMI) is a common measure used to assess body composition. For boxers, maintaining weight within the optimal range is crucial for peak performance. Additionally, reaction speed is a key skill in boxing; the ability to quickly respond to an opponent’s moves can significantly impact match outcomes.Material and Methods. This cross-sectional study utilized quantitative data analysis. Primary data included body weight, height, and reaction speed from a sample of 12 PPLOP Central Java boxing athletes. Data normality was assessed using the Shapiro-Wilk test, while the linearity test evaluated whether the relationships between variables were linear. Bivariate correlation tests were conducted. The study used Body Mass Index and Hand Touch Reaction tests with validity levels of 0.98 and 0.323, respectively, for measuring body weight, height, and reaction speed.Results. There is a relationship between body weight and reaction speed with a sig value of .003 <0.05 with a negative relationship direction. 2. there is no relationship between height and reaction speed with a sig value of (0.798>0.05) with a negative relationship direction, 3. there is a relationship between body mass index and reaction speed with a sig value of .001 <0.05 with a negative relationship directionConclusion. Based on the results of the study it can be concluded that there is a linear relationship between body weight and reaction speed, there is no linear relationship between height and reaction speed and there is a linear relationship between body mass index and reaction speed.

Abstract

This research evaluates the effectiveness of using the D'Volleyball Learning website to learn volleyball at SMA Negeri 1 Indralaya Utara. Using the Classroom Action Research (PTK) method with two action cycles, this research involves instruments such as knowledge tests, lower service skills assessments, and attitude assessments. Data collection techniques include tests, observation, and documentation, with analysis based on learning completeness. The research subjects were 21 students in class XII.IPS.2, consisting of 11 men and 10 women. The results of the cycle I showed knowledge completeness of 42.9% with an average score of 69.4, bottom serve skill at 52.3% with an average of 59, and attitude of 42.9% with an average of 60.2, resulting in an overall average of 46% in the sufficient category. In cycle II, knowledge completeness increased to 85.7% with an average of 88; bottom serve skills to 80.9% with an average of 76.6; and attitude to 85.8% with an average of 80.5, resulting in an overall average of 84.1% in the outstanding category. In addition, student activity increased from 71.3% (active) in cycle I to 80.6% (very active) in cycle II. In conclusion, using the D'Volleyball Learning website has proven effective in improving volleyball learning at SMA Negeri 1 Indralaya Utara.
