Abstract


Bertujuan untuk mengetahui jenis cairan rehidrasi mana yang mempercepat pemulihan setelah olahraga. Metode yang digunakan quasi eksperimen  dengan desain pretest-posttest Group Design untuk membandingkan efek rehidrasi air minum, elektrolit dan elektrolit+glukosa. Subjek adalah 20 orang atlet sepakbola di klub Mandala. Pengukuran berat badan, denyut nadi, tekanan darah sebelum dan setelah latihan fisik selama 45 menit, serta lama periode pemulihan pada pemberian tiap jenis cairan rehidrasi dilakukan 2 kali dengan interval waktu 3 hari. Variabel-variabel tersebut dibandingkan antara ke 3 jenis cairan. Analisis dilakukan dengan menggunakan metoda Repeated Measure untuk variabel yang berdistribusi normal dan metoda Friedman untuk variabel yang tidak berdistribusi normal serta dilanjutkan dengan regresi linier berganda untuk mengontrol variabel pengganggu. Hasil penelitian menunjukkan; Ada perbedaan efek pemberian ke 3 jenis cairan rehidrasi terhadap peningkatan denyut nadi setelah latihan fisik. Cairan rehidrasi air minum menghasilkan peningkatan denyut nadi terkecil yaitu sebesar 28 kali/menit dibandingkan dengan 39 kali/menit pada pemberian cairan elektrolit dan 45 kali/menit pada pemberian cairan elektrolit+glukosa. Tidak ada perbedaan peningkatan tekanan darah sistolik dan diastolik setelah pemberian 3 jenis cairan tersebut. Tidak ada perbedaan periode pemulihan denyut nadi, tekanan darah sistolik dan diastolik setelah pemberian 3 jenis cairan rehidrasi. Simpulan; pemberian cairan air minum memberikan hasil yang terbaik pada latihan fisik selama 45 menit.

Kata Kunci: cairan rehidrasi; denyut nadi; tekanan darah; lama periode pemulihan


Abstract

This study aimed to find the best rehydration solution for recovery after exercise. The method of this research is quasy experiment with pretest-postest design study was conducted to compare the rehydration effect of water, electrolyte and glucose-electrolyte. The subjects were 20 football athletes of Mandala football club. Body weight, heart rate, blood pressure at pre and post 45 minutes exercise and the recovery period were done twice by 3 days interval for three weeks. Those measurements at 3 kinds of rehydration solutions were comparid. Analysis was conducted by repeated measure for normally distributed variables and friedman for not normally distributed variables and followed by multiple linear regresion for controlling the confounding variable. The result are; drinking water solution gave the smallest increase of heart rate (28 X/minutes) compared to electrolyte solutions (39 X/minutes) and electrolyte-glucose solutions (45 X/minutes). There were no difference in systolic and diastolic blood pressure increase after the three different rehydration solution consumption. There was no difference in the recovery period of heart rate, systolic and diastolic blood pressure after the three different rehydration solution consumption.The conclusion is drinking water showed the best effect as a rehydration solution for 45 minute exercise.

Keywords: rehydration solution; heart rate; blood pressure recovery period
