SUMMARY
Football is a sport with a high intensity of physical activity that combines strength, endurance, and speed so that it triggers excessive sweating and is at risk of dehydration which can reduce athlete performance. It is necessary to regulate fluid intake to prevent dehydration by providing natural drinks that contain carbohydrates and electrolytes. The purpose of study was analysing the effect of Mabel's sport drink (honey and star fruit juice) on blood pressure, oxygen saturation, and maximal oxygen volume of soccer athletes compared to commercial isotonic and plain water. The type of research was used quasi experimental with pretest-posttest design by subject design. The research subjects were SSB KKK with an age range of 14-16 years totalling 14 people. An intervention was given in the form of a Mabel sport drink, commercial isotonic, and 250 ml of water with a washout for 6 days between the interventions given. The measurement of VO2Max was carried out using the balke test method. Measurements of blood pressure and oxygen saturation were carried out 15 minutes after measuring VO2Max. Data analysis using paired sample t-test and Anova test followed by Post hoc LSD test. The results was showed intervention in the form of a Mabel sports drink based on the results of the paired t test showed that there was a difference in systolic (p=0.016) and diastolic (p=0,008) blood pressure, oxygen saturation (p=,.035), and VO2max (p=0,000). The results of the post hoc LSD test on the VO2max variable showed a significant difference between Mabel's sport drink intervention compared to water (p=0,000). The conclusion was no difference in the effectiveness of the interventions given to blood pressure and oxygen saturation. Mabel's sports drink intervention and commercial isotonic drinks can increase the VO2max of soccer athletes.Sepak bola merupakan olahraga dengan intensitas aktifitas fisik tinggi yang mengombinasikan kekuatan, daya tahan, dan kecepatan sehingga memicu pengeluaran keringat yang berlebih dan berisiko mengalami dehidrasi yang dapat menurunkan performa atlet. Perlu adanya pengaturan asupan cairan untuk mencegah terjadinya dehidrasi dengan pemberian minuman berbahan alami yang memiliki kandungan karbohidrat dan elektrolit. Tujuan penelitian adalah untuk menganalisis pengaruh sport drink Mabel (madu dan sari belimbing wuluh) terhadap tekanan darah, saturasi oksigen, dan volume oksigen maksimal atlet sepak bola dibandingkan dengan isotonik komersial dan air putih. Jenis penelitian yang digunakan adalah quasi eksperimental dengan rancangan pretest-posttest by subject design. Subjek penelitian adalah SSB KKK dengan rentang usia 14-16 tahun berjumlah 14 orang. Diberikan intervensi berupa sport drink Mabel, isotonik komersial, dan air putih sebanyak 250 ml dengan pemberlakuan washout selama 6 hari diantara intervensi yang diberikan. Pengukuran VO2Maks dilakukan dengan metode tes balke. Pengukuran tekanan darah dan saturasi oksigen dilakukan 15 menit setelah pengukuran VO2Maks. Analisis data menggunakan uji Paired sampel t-test dan Anova dilanjutkan dengan uji post hoc LSD. Hasil penelitian menunjukkan intervensi berupa sport drink Mabel berdasarkan hasil uji t berpasangan menunjukkan terdapat perbedaan tekanan darah sistolik (p=0,016) dan diastolik (p=0,008), saturasi oksigen (p=0,035), dan VO2Maks (p=0,000). Hasil uji post hoc LSD pada variabel VO2Maks terdapat perbedaan bermakna intervensi sport drink Mabel dibandingkan air putih (p=0,000). Kesimpulan penelitian adalah intervensi yang diberikan tidak terdapat perbedaan efektivitasnya terhadap tekanan darah dan saturasi oksigen. Intervensi sport drink Mabel dan minuman isotonik komersial dapat meningkatkan VO2Maks atlet sepak bola.
