Abstract

Permainan lari estafet merupakan salah satu aktivitas olahraga yang dapat digunakan dalam pembelajaran Pendidikan Jasmani, Olahraga, dan Kesehatan (PJOK) untuk meningkatkan kemampuan fisik peserta didik, khususnya kecepatan lari. Penelitian ini bertujuan untuk mengetahui pengaruh permainan lari estafet terhadap kecepatan remaja melalui metode observasi. Penelitian menggunakan pendekatan deskriptif kualitatif dengan teknik pengumpulan data berupa observasi terhadap aktivitas siswa selama mengikuti permainan lari estafet. Hasil observasi menunjukkan bahwa permainan lari estafet mampu meningkatkan kecepatan lari siswa, meningkatkan semangat belajar, memperbaiki koordinasi gerak, serta meningkatkan kerja sama antar anggota kelompok. Selain itu, siswa menunjukkan perubahan positif dalam kemampuan berlari dan pergantian tongkat estafet setelah mengikuti latihan secara rutin. Faktor yang memengaruhi peningkatan kecepatan siswa meliputi kondisi fisik, kekuatan otot kaki, teknik berlari, motivasi, serta kerja sama tim. Permainan lari estafet juga memberikan suasana pembelajaran yang lebih menyenangkan sehingga siswa lebih aktif dalam mengikuti kegiatan olahraga. Berdasarkan hasil penelitian, dapat disimpulkan bahwa permainan lari estafet memberikan pengaruh positif terhadap peningkatan kecepatan remaja serta mendukung perkembangan keterampilan motorik dan sosial siswa.

Abstract

This study aimed to analyze the kinematic characteristics of the Ushiro Mawashi Geri kick performed by karate athletes using Dartfish motion analysis software. The study employed a qualitative descriptive approach involving five male karate athletes selected through purposive sampling based on specific criteria. Data were collected through observation, video documentation, kicking performance tests, and motion analysis using Dartfish software. The analysis focused on the preparation, execution, and follow-through phases of the kick. The findings showed that the athletes generally demonstrated good performance in executing the Ushiro Mawashi Geri technique. The Dartfish analysis results indicated 3.33% in the excellent category, 73.67% in the good category, 13.00% in the poor category, and 10.00% in the very poor category. Several technical weaknesses were still identified, particularly in body balance, movement coordination, and foot positioning during the rotational and follow-through phases. This study concludes that kinematic analysis using Dartfish software can be utilized as an evaluation tool to improve the effectiveness and efficiency of Ushiro Mawashi Geri techniques in karate training. However, due to the limited number of participants, the findings are exploratory and cannot be generalized broadly.

Abstract

This study was motivated by the low level of fundamental locomotor skills among elementary school students, which was influenced by the limited variation and innovation in physical education learning media. The study aimed to examine the effectiveness of movement exploration learning media in improving students’ locomotor skills. A quantitative experimental method with a pretest and posttest control group design was employed. The participants consisted of 30 elementary school students who were divided into an experimental group and a control group. The instrument used was a locomotor skill test covering walking, running, jumping, and hopping. Data were analyzed using statistical tests to compare improvements between groups. The results showed a significant increase in locomotor skills in both groups, with the experimental group demonstrating higher improvement than the control group. The findings indicated that movement exploration learning media effectively enhanced students’ active participation and improved learning outcomes in physical education. The novelty of this study lies in the application of exploration based learning media that provides contextual and enjoyable movement experiences for elementary school students.

Abstract

Kemampuan gerak merupakan elemen krusial dalam menentukan performa maksimal atlet atletik, khususnya pada nomor sprint. Penelitian ini bertujuan untuk menganalisis secara mendalam pengaruh kombinasi metode latihan koordinasi dan drill terhadap peningkatan kemampuan gerak serta mengidentifikasi kendala yang dihadapi oleh atlet. Metode penelitian yang digunakan adalah kualitatif deskriptif dengan pendekatan studi kasus. Data primer dihimpun melalui teknik wawancara mendalam (in-depth interview) terstruktur dengan satu orang pelatih kepala dan satu orang atlet sprint nomor 100–200 meter di Klub Physical Center Stadion UNIMED pada Mei 2026. Analisis data dilakukan secara deskriptif kualitatif yang kemudian dikuantifikasikan ke dalam matriks penilaian indikator capaian motorik berbasis skor bertingkat (skala 1-4). Hasil penelitian menunjukkan bahwa penerapan variasi latihan seperti ABC running, agility ladder, speed training, plyometric, drill cone, dan mini hurdle secara signifikan meningkatkan komponen koordinasi tubuh dan kelincahan atlet dari kategori "Cukup" menjadi "Sangat Baik". Namun, grafik perkembangan motorik ini bersifat fluktuatif dan terkendala oleh kapasitas penalaran kognitif atlet terhadap instruksi gerakan yang rumit, terutama pada penguasaan teknik start (block start). Penelitian ini menyimpulkan bahwa implementasi periodisasi latihan yang adaptif-berfokus pada gerak dasar untuk anak usia dini dan pengenalan teknik kompleks untuk usia remaja-terbukti efektif mengoptimalkan kompetensi motorik atlet secara berkelanjutan.

Abstract

Background: Arm explosive power, hand eye coordination, and overhead-serve performance are related components of youth volleyball, but their cross-sectional associations require cautious interpretation. Objective: This study examined a prespecified pathway model linking arm explosive power and hand–eye coordination with two serve-test scores among junior high school extracurricular athletes. Method: Twenty students aged 13–15 years (9 boys and 11 girls) were purposively selected from 40 program members. Two regression submodels were estimated. Because all measures were collected in one fixed-order session and the two serve tests both used landing-zone scores, the analysis is descriptive and does not establish temporal or causal mediation. Results: Arm explosive power (β = .542, p = .004) and hand–eye coordination (β = .417, p = .019) were associated with the overhead-serve score. In the accuracy submodel, arm explosive power (β = .310, p = .019), hand–eye coordination (β = .334, p = .007), and the overhead-serve score (β = .476, p = .003) were associated with accuracy. Adjusted R² values were .557 and .856. Standardized indirect associations were .258 and .198. Sobel results were p = .016 and p = .038, respectively, but no bootstrap confidence intervals were available. Conclusion: The observed coefficients are consistent with the hypothesized pathway model in this selected sample, but small-sample instability, selection bias, unmeasured confounding, and operational overlap between the two serve tests limit inference and generalizability.

Abstract

Background: Markerless motion analysis can enrich coaching feedback with objective movement information, but evidence linking it to both physical literacy and functional movement outcomes in novice athletes remains limited. Aims: This study examined whether an eight-week Smart Coaching program supported by markerless motion analysis was associated with greater short-term change than conventional coaching. Methods: A nonrandomized quasi-experimental pretest-posttest control-group design involved 60 novice athletes aged 12-15 years (30 per group). Both groups trained three times weekly for eight weeks. Physical literacy was assessed with an adapted CAPL-2 composite and movement quality with the Functional Movement Screen (FMS). Separate 2 × 2 mixed ANOVAs tested Time × Group effects. Results: Smart Coaching increased CAPL-2 scores from 55.03 ± 6.69 to 73.64 ± 6.51 and FMS scores from 11.37 ± 1.92 to 16.60 ± 1.54. Corresponding gains were 18.61 and 5.23 points, compared with 7.64 and 1.43 points under Conventional Coaching. Time × Group interactions were significant for physical literacy, F(1, 58) = 48.31, p < .001, partial η² = .454, and FMS, F(1, 58) = 77.20, p < .001, partial η² = .571. Between-group differences in change were 10.97 points (95% CI 7.81-14.13) and 3.80 points (95% CI 2.93-4.67), respectively. Conclusion: In this single-site nonrandomized study, Smart Coaching with markerless motion analysis was associated with larger short-term improvements in both outcomes. Randomized and longitudinal replication is warranted.
