Abstract

This study aims to analyze the effect of arm muscle strength training on underarm passing skills in volleyball for upper-grade male students at Maubeli Elementary School, North Central Timor Regency. The study used a quantitative approach with a one-group pretest–posttest design. The population and sample size were 20 students (total sampling). The treatment, arm muscle strength training, was given in a structured manner over five sessions. Data analysis included descriptive statistics, residual normality tests, and simple linear regression. The results showed a correlation coefficient (R) of 0.458 and a determination coefficient (R²) of 0.210, indicating that 21.0% of the variation in underarm passing skills was influenced by arm muscle strength. The ANOVA test showed F count = 4.774 with Sig. = 0.042 (<0.05), indicating that arm muscle strength training significantly influenced underarm passing skills. The regression equation obtained was Y = 0.080 + 0.683X. These findings confirm that an arm muscle strength training program can be used as a physical education (PJOK) learning strategy to improve the quality of basic volleyball underarm passing techniques in elementary school students. Keywords: Arm muscles, strength training, underhand passing, volleyball, elementary school students

Abstract

The forward roll skill among primary school pupils remains relatively low, as some pupils experience difficulties with the movement sequence, lack flexibility, and feel anxious when performing the movement. This study aims to improve the forward roll skill among Year 5 pupils at Maol State Primary School through the use of an inclined mat as an aid. The study employed the Classroom Action Research (CAR) method, conducted over two cycles, each comprising the planning, implementation, observation, and reflection stages. The research subjects consisted of 25 pupils. Data were collected through observation of pupil activities and forward roll skill tests using a psychomotor assessment rubric, and were subsequently analysed descriptively to assess improvements in learning outcomes across each cycle. The results of the study indicate that the use of the inclined mat was effective in improving students’ forward roll skills. In cycle I, an average score of 73.08 was obtained with a mastery rate of 56%, whilst in cycle II this increased to an average of 78.40 with a mastery rate of 80%, thus exceeding the research target of at least 75% of students achieving the Minimum Mastery Criteria. In addition to improving learning outcomes, the use of the inclined mat also helped to reduce fear and boost students’ confidence when performing the movement
