Enhancing Long Jump Performance Through Agility And Strength-Based Physical Fitness Training: A Classroom Action Research

Abstrak

The long jump is a complex athletic activity that requires explosive power, agility, coordination, and effective movement control. However, many elementary school students experience difficulties in achieving optimal jump performance due to inadequate physical conditioning, particularly in lower-limb strength and agility. This study aimed to evaluate the effectiveness of agility and strength-based physical fitness training in improving the long jump performance of students at UPT SD Negeri 42 Waetuwo. The study employed a Classroom Action Research (CAR) design involving 20 students. The research was conducted in two cycles, each consisting of planning, acting, observing, and reflecting stages. The intervention integrated agility drills, including ladder drills and cone drills, with strength exercises such as squat jumps, lunges, and plyometric activities within PJOK learning sessions. Data were collected using long jump performance tests and observation sheets, then analyzed using descriptive statistical techniques. The pre-cycle findings revealed low student competence, with a mean score of 62.45 and 0% classical completeness. Following the implementation of foundational agility and strength training in Cycle I, the mean score increased to 71.30 with 35% classical completeness. In Cycle II, after introducing more intensive explosive power exercises and refined take-off drills, the mean score improved significantly to 78.90, with 90% of students achieving the Minimum Mastery Criteria (KKM 75). The findings indicate that integrated physical fitness training focusing on biomotor components, particularly agility and leg strength, is more effective than conventional technique-oriented instruction alone. This approach provides students with the physical foundation necessary to perform athletic techniques more efficiently and confidently.
