Physical Fitness of Students in the Futsal Extracurricular at SMP Negeri 9 Semarang

Abstract

Physical fitness is a key determinant of performance in high-intensity intermittent sports like futsal, which require the simultaneous integration of aerobic capacity, strength, explosive power, agility, and coordination. This study aimed to analyze the physical fitness levels of students participating in futsal extracurricular activities at SMP Negeri 9 Semarang as a basis for designing a data-driven training program. The study used a quantitative descriptive survey approach with a total sample of 20 students. The measurement instrument referred to the Indonesian Student Fitness Test (TKSI) Phase D, which includes five components: hand-eye coordination, abdominal muscle strength (sit-ups), leg muscle explosive power (standing broad jump), agility (T-test), and aerobic endurance (beep test). Data were analyzed by converting total scores into TKSI norm categories. The results showed that 80% of students were in the moderate category, 5% in the good category, and 15% in the poor category, with no categories in the very good or very poor categories. Empirically, these findings indicate that participation in futsal extracurricular activities has not been fully followed by optimal fitness levels required to support the demands of game performance. Conceptually, the moderate category reflects adequate basic capacity but is not yet competitive. Therefore, a more systematic, progressive, and periodized training program is needed, accompanied by regular fitness evaluations, to comprehensively and sustainably improve students' physical quality.
