Abstract

Olahraga adalah salah satu faktor penting yang berpengaruh terhadap kesehatan manusia terutama dalam hal kesehatan mental, di mana kesehatan mental sendiri sangat mendukung kemampuan kita dalam menjalani berbagai aktivitas. Penelitian ini bertujuan untuk mengetahui hubungan antara mental toughness dengan motivasi berprestasi tim ekstrakurikuler softball di sekolah SMAIT Raudhatul Jannah Kota Cilegon. Penelitian ini merupakan penelitian korelasional, sampel penelitian menggunakan teknik total sampling. Total sampling merupakan teknik pengambilan sampel di mana seluruh populasi digunakan sebagai sampel penelitian. Dalam penelitian ini sampel sebanyak 30 atlet total dari keseluruhan anggota tim ekstrakurikuler softball di SMAIT Raudhatul Jannah Kota Cilegon. Teknik pengumpulan data yang digunakan adalah dengan pemberian kuesioner kepada responden yang menjadi subjek dalam penelitian. Teknik analisis data dalam penelitian ini adalah dengan menggunakan analisis statistik deskriptif dan statistik inferensial. Hasil penelitian menunjukkan bahwa terdapat hubungan yang signifikan antara mental toughness dan motivasi berprestasi dengan kontribusi sebesar 45,4%. Berdasarkan hasil temuan pada penelitian ini maka didapati beberapa saran yang dapat menunjang penelitian ini yaitu, penelitian ini dapat ditindak lanjuti dengan beberapa penelitian lainnya terutama dalam bidang psikologinya, responden penelitian yang masih kecil cakupannya dan diharapkan untuk penelitian selanjutnya dapat dilakukan pada jumlah koresponden yang lebih besar, dan bagi peneliti selanjutnya agar melakukan pengawasan lebih ketat pada saat pengambilan data agas hasilnya lebih objektif.

Abstract

Tujuan dalam penelitian ini adalah untuk mengetahui pengaruh latihan skipping rope dan ladder drill terhadap kelincahan mahasiswa spesialisasi karate di Jurusan PKO Universitas Negeri Medan. Penelitian ini adalah penelitian eksperimen semu dengan metode two groups pretest-posttest design. Populasi dalam penelitian ini adalah mahasiswa kelincahan mahasiswa spesialisasi karate di Jurusan PKO Universitas Negeri Medan. Sampel dalam penelitian ini berjumlah 20 mahasiswa spesialisasi karate di Jurusan PKO Universitas Negeri Medan dengan teknik purposive sampling. Instrumen yang digunakan dalam penelitian ini menggunakan hexagonal obstacle agility test. Teknik analisis data yang digunakan untuk uji hipotesis adalah analisis uji t (paired sample t test). Berdasarkan hasil analisis data dan pembahasan uji t pertama diperoleh nilai t hitung (3.042) > t tabel (1.812), dan nilai p (0.014) < dari 0,05, hasil tersebut diartikan ada pengaruh penggunaan skipping rope terhadap kelincahan. Dengan besarnya nilai rata-rata posttest yang diberikan sebesar (15.83). Sedangkan uji t kedua diperoleh nilai t hitung (0.061) < t tabel (1.812), dan nilai p (0.953) >dari 0,05, hasil tersebut diartikan ada ada perbedaan antara sebelum diberikan perlakuan dan sesudah latihan ladder drill terhadap peningkatan kelincahan. Dengan besarnya nilai ratarata posttest (16.49). Berdasarkan hasil tersebut dapat disimpulkan pengaruh penggunaan skipping rope lebih meningkat secara signifikan dalam meningkatkan kelincahan terhadap kelincahan mahasiswa spesialisasi karate di Jurusan PKO Universitas Negeri Medan.

Abstract

Purpose: Football has increasingly become a multidisciplinary field that integrates not only physical and tactical elements but also technological advancements to enhance decision-making. One of the prominent developments in this domain is the application of machine learning (ML) techniques to analyze match-related data, assess player performance, and optimize team strategies. This study aims to conduct a systematic literature review of contemporary research that employs machine learning algorithms within the context of football. Materials and Methods: A total of 50 scientific articles were initially retrieved from various reputable databases. Following a rigorous screening and eligibility assessment, 30 articles were selected for detailed analysis. Result: These studies employ diverse machine learning approaches, including Support Vector Machines (SVMs), Random Forests, XGBoost, Deep Learning, and clustering methods, for a wide range of purposes, such as match outcome prediction, player performance evaluation, injury detection, and playing position classification. The findings of this review underscore the potential of machine learning to contribute significantly to data-driven decision-making in football, providing valuable insights for coaches, performance analysts, and club management. Conclusion: Furthermore, this study identifies key challenges that remain, including data quality, data availability, and the interpretability of complex models. This review will serve as a critical reference for researchers and practitioners advancing intelligent technologies in sports, with particular emphasis on football.

Abstract

This study aims to analyze the role of sports philosophy in shaping the professional identity of sports coaches through the integration of ontological, epistemological, and axiological dimensions. The background of the study is based on the tendency of coaching practices to emphasize technical and managerial aspects, while the philosophical foundation has not been studied comprehensively. The study uses a literature review approach with an analytical-conceptual design through the stages of identification, selection, evaluation, and synthesis of relevant scientific sources. The results of the study indicate that the ontological dimension shapes coaches' awareness of the nature of sport as a process of developing a whole person; the epistemological dimension emphasizes the importance of integrating scientific knowledge and critical reflection in coaching practice; while the axiological dimension emphasizes the internalization of ethical values, sportsmanship, and moral responsibility. The discussion emphasizes that the professionalism of coaches is not only determined by technical competence, but also by the consistency of values ??and philosophical reflection that underlie their practice. This study concludes that sports philosophy plays a fundamental role in building a professional identity of coaches oriented towards character, integrity, and social responsibility.

Abstract

This study aims to analyze the effectiveness of Tabata-based sport rhythm training in improving VO₂max among students of the Sports Coaching Education program at the Faculty of Sports Science, Universitas Negeri Medan. The study employed a quasi-experimental design using a pretest–posttest control group approach. The sample consisted of 30 students selected through random sampling, who were then divided into two groups: an experimental group and a control group. The instrument used to measure VO₂max was the Multistage Fitness Test (bleep test). The intervention was conducted over six weeks, with training sessions three times per week. Data were analyzed using paired sample t-tests and independent sample t-tests with a significance level of 0.05. The results indicated a significant improvement in VO₂max in the experimental group following the Tabata-based sport rhythm training intervention (p < 0.05). Furthermore, there was a significant difference between the experimental and control groups in the posttest results, demonstrating that the applied training method was more effective than conventional training. This improvement can be attributed to the characteristics of Tabata training, which combines high intensity with short intervals, thereby optimizing aerobic capacity. In conclusion, Tabata-based sport rhythm training is effective in improving VO₂max among students of Sports Coaching Education. This method can serve as an alternative training model to enhance cardiorespiratory fitness efficiently and systematically.
