Daftar Isi:
- Tujuan penelitian ini membuktikan efek dehidrasi sampai dengan 2.8% terhadap prestasi lari 400 meter. Permasalahan dalam penelitian secara praktis kesadaran akan hidrasi ketika melakukan aktivitas jasmani terutama olahraga masih kurang, sehingga perlu bukti untuk mengetahui pengaruh dehidrasi terhadap kinerja terutama pelaku olahraga. Metode penelitian dengan quasi one group pretest post test desain. Sampel terdiri dari 25 mahasiswa pendidikan kepelatihan olahraga 6 putri dan 19 putra. Dilakukan prosedur, pengukuran berat badan, tes lari 400 meter, penghitungan dehidrasi 2.8% dari berat badan, dan tes lari 400 meter. Treatment dehidrasi sampai 2.8% berjemur pasif dengan mengenakan jas hujan. Hasil penelitian menunjukkan bahwa data tidak berdistribusi normal. Data dianalisis dengan Uji non parameterik Wilcoxon. Hasil perhitungan menunjukkan nilai signifikansi sebesar 0.000 yang menunjukkan terjadi perbedaan prestasi lari sebelum dan sesudah dehidrasi. Waktu tempuh rerata 112.48 detik menjadi 146.32 detik, terjadi kenaikan waktu tempuh 30%. Implikasi hasil penelitian ini adalah untuk olahraga prestasi, perlu diperhatikan level hidrasi atlet agar prestasi tidak mengalami penurunan drastic dan perlu upaya untuk mengatur asupan cairan.
- This study aims to authenticate the effect of 2.8% dehydration on 400-meter running performance. The research problem is based on the lacking of hydration level awareness while performing physical activities. Hence, the study on the effect of 2.8% dehydration on sports performance is important to be carried out. This research applies one group pre-test and post-test design. The samples consist of 25 sports coaching education students; 6 females and 19 males. The procedures performed are body weight measurement, 400-meter running test, and dehydration calculation of 2.8% of body weight. The treatment for dehydration is up to 2.8% in passive sunbathing wearing a raincoat. The result shows that the data is not normally distributed. The significance of the Wilcoxon test is 0.000, which means there are statistically significant differences in running achievement before and after dehydration. The average travel time increases from 112.48 seconds to 146.32 seconds, which means 30% increase. The suggestions of this study, especially for performance sports, are the athlete's hydration level must be monitored so that performance does not decrease drastically, and fluid intake should be managed appropriately.
