Abstract

Smoking is a behavioral factor that can reduce athletic fitness, but the comparison of VO₂ max capacity between smokers and non-smokers in soccer players is still rarely studied. This study aims to analyze the differences in VO₂ max between two groups of players at Fortuna FC, Kupang. The study employed a quantitative comparative design involving 20 participants (10 smokers and 10 non-smokers). VO₂ max was measured using the Multistage Fitness Test (Beep Test) and analyzed using an independent sample t-test. The results showed a significant difference between the groups (t(18) = 8.639; p < 0.001), with a higher average VO₂ max in non-smokers (54.7 mL·kg⁻¹·min⁻¹) compared to smokers (48.9 mL·kg⁻¹·min⁻¹). This difference of 5.8 mL·kg⁻¹·min⁻¹ indicates a decrease in aerobic capacity of approximately 10–12% in smokers. These findings confirm that smoking negatively impacts the cardiorespiratory fitness of amateur soccer players. This study provides relevant empirical evidence for coaches and sports health professionals to promote smoking prevention programs in the development of athletes.

Abstract

Purpose: This study aims to analyze the role of basic stance techniques in pencak silat learning to improve PJOK learning outcomes among students. Materials and Methods: This study employed a literature review approach by analyzing six selected scientific articles published within the last ten years. The data were collected from databases such as Google Scholar, PubMed, and ScienceDirect using keywords related to pencak silat, stance techniques, and PJOK learning. Result: The findings indicate that mastery of basic stance techniques significantly contributes to improving students’ motor skills, balance, coordination, and understanding of movement concepts. In addition, the use of instructional media such as video tutorials and interactive multimedia enhances student motivation and learning outcomes. Conclusion: Basic stance techniques play a fundamental role in improving the effectiveness of PJOK learning. Therefore, they should be emphasized as a core component in pencak silat instruction in schools.
