Kopi telah menjadi minuman yang sangat signifikan dalam kehidupan sehari-hari. Telah diketahui bahwa kopi dapat mengurangi kelelahan, sehingga menjadi salah satu peningkat performa yang paling dicari. Dengan kandungan kafein sebagai salah satu senyawa bioaktif utamanya, kopi juga diteliti untuk efek ergogeniknya dalam kompetisi olahraga. Namun, penelitian tentang jenis kopi spesifik dan olahraga masih terbatas. Penelitian ini merupakan studi eksperimental dengan desain post-test only. Sebanyak 15 atlet sepak bola pria berusia 18-23 tahun menjalani latihan intensitas tinggi untuk menilai tingkat kelelahan perifer mereka. 8 atlet diberi double shot espresso Arabika Gayo 30 menit sebelum sprint 300 meter, sedangkan 7 lainnya sebagai kelompok kontrol. Kadar laktat darah diukur melalui sampel darah ujung jari segera setelah sesi latihan. Selanjutnya, tes langkah YMCA diberikan untuk mengevaluasi VO2max setelah periode istirahat singkat. Subjek dalam eksperimen dipilih berdasarkan kriteria inklusi dan eksklusi tertentu. Penelitian ini bertujuan untuk menganalisis pengaruh espresso Arabika Gayo terhadap kelelahan otot akibat latihan intensitas tinggi pada atlet sepak bola. Tidak ada pengaruh signifikan dari espresso Arabika Gayo terhadap kadar laktat darah (kontrol = 8,97 ± 1,01 dan percobaan = 10,2 ± 1,238; p = 0,058) dan VO2max (kontrol = 48,43 ± 2,77 dan percobaan = 47,19 ± 3,499, p = 0,464). Konsumsi double shot espresso Arabika Gayo 30 menit sebelum latihan intensitas tinggi tidak memiliki efek signifikan secara statistik terhadap kelelahan otot akibat latihan intensitas tinggi pada atlet sepak bola.

Coffee has been around as a very significant beverage in daily lives. It has come to attention that coffee is reported to ease fatigue, hence becoming one of the most sought performance enhancer. With how coffee contains caffeine as one of its main bioactive compound, it’s also being researched for its ergogenic effect for sport competition. However, investigations into the specific types of coffee and sports is limited. This research was an experiment study with post-test only design. A total of 15 male football athletes aged 18-23 years old underwent high intensity training to assess their peripheral fatigue level. 8 athletes were given double shot of Arabica Gayo espresso 30 minutes before a 300 metres sprint, while the remaining 7 was served as control group. Blood lactate levels were measured via fingertip blood samples immediately following the training session. Subsequently, YMCA step test was administered to evaluate VO2max after a brief rest period. The subjects in the experiment were selected based on specific inclusion and exclusion criteria. This study aimed to analyse the effect of Arabica Gayo espresso towards muscle fatigue from high intensity training in football athletes. There was no significant effect of Arabica Gayo espresso towards blood lactate level (control = 8,97 ± 1,01 and trial = 10,2 ± 1,238 ; p = 0.058) and VO2max (control = 48,43 ± 2,77 and trial = 47,19 ± 3,499 , p = 0.464). The consumption of Arabica Gayo espresso double shot 30 minutes before high intensity training has no statistically significant effect towards muscle fatigue from high intensity training in football athletes.
