Abstract

Latihan High-Intensity Interval Training (HIIT) merupakan metode yang efektif dalam meningkatkan kapasitas aerobik atlet melalui kombinasi kerja intensitas tinggi dan periode pemulihan singkat. Penelitian ini bertujuan untuk mengetahui pengaruh latihan HIIT terhadap peningkatan VO₂Max pada atlet badminton. Metode penelitian menggunakan desain one-group pretest–posttest dengan sampel sebanyak 30 atlet badminton. Pengukuran VO₂Max dilakukan menggunakan Multistage Fitness Test sebelum dan sesudah program latihan HIIT. Analisis data menggunakan Paired Sample T-Test. Hasil penelitian menunjukkan adanya peningkatan yang signifikan pada VO₂Max setelah mengikuti program HIIT. Rata-rata nilai VO₂Max meningkat dari 44,50 ml/kg/menit pada pretest menjadi 47,67 ml/kg/menit pada posttest. Uji Paired Sample T-Test menghasilkan nilai signifikansi 0,000 (< 0,05) yang menunjukkan adanya perbedaan signifikan antara nilai VO₂Max sebelum dan sesudah latihan. Dengan demikian, latihan HIIT terbukti efektif dalam meningkatkan kapasitas aerobik atlet badminton. Program ini dapat direkomendasikan kepada pelatih sebagai model latihan yang efisien dan sesuai dengan karakteristik permainan badminton yang bersifat intermittent

Abstract

Doping is a serious problem in the world of sports that can undermine sportsmanship, health, and the integrity of athletes. College athletes’ limited understanding of banned substances and the lack of anti-doping education increase the risk of doping violations, whether intentional or unintentional. This study aims to determine the effect of anti-doping education on the knowledge and attitudes of Unsika volleyball club athletes. The study used a quantitative approach with a quasi-experimental method through a One-Group Pretest-Posttest Design. The study sample consisted of 30 athletes selected using total sampling. Data collection was conducted using a knowledge test and an attitude questionnaire, followed by analysis using the Shapiro-Wilk normality test and the Paired Sample T-Test. The results showed an increase in the mean score from 58.70 in the pretest to 82.67 in the posttest. The results of the Paired Sample T-Test showed a significance value of 0.000 < 0.05, indicating a significant effect of anti-doping education on athletes’ knowledge and attitudes. Thus, anti-doping education has proven effective in enhancing athletes’ understanding and fostering positive attitudes toward the importance of sportsmanship and doping-free sports.
