Balanced diet is an eating patternthat focuses on the type of food eatenby person, including staple foods, animal protein and vegetable protein, vegetables and fruits. Application of balanced diet accompanied by the fulfillment of fluid needs in athletes has a role supporting the athletes’ performance. However, many athletes have not understood the urgency of balanced diet and the fulfillment of fluid requirements in improving athlete's performance yet. Nutrition education is a solution that can be used to improve the athlete's knowledge about the urgency of balanced diet and fluid requirements fulfillment. Community devotion done to increase athletes’ knowledgewas nutrition education about balanced diet and fluid requirements. Nutrition education performed to 21 soccer athletes at Sekolah Sepak Bola (SSB) Real Madrid on May 08, 2018 at the Stadium of Universitas Negeri Yogyakarta. There was an increase of athlete knowledge between preeducation (56,67 ± 18,33) and post-education (75,24 ± 14,70), with p-value <0,001. Nutrition education can increase athletes' knowledge about balanced nutrition and fluid requirements effectively.Keywords: nutrition education, balanced diet, fluid requirement, knowledge, soccer

Training is conducted to improve physiological functions that can support improvement of cardio-respiratory function (O2max). However, intensive training can lead to oxidative stress, which can contribute to health problems. The purpose of this study was to evaluate the effect of training on serum lipid peroxidation levels in student soccer players. The study was pre-experimental study with a one-shot case design conducted in April 2014. Twelve student soccer players from UGM who chosen by purposive sampling and met the inclusion and exclusion criteria were involved in the study. Each subject received training in the form of O2max measurements using the yo-yo intermittent recovery test. Plasma malondialdehyde (MDA) levels were measured using the thiobarbituric acid method 30 min after O2max measurement. Pearson correlation was used to analyze the correlation between O2max and plasma MDA levels. The mean age of subject was 19.25±1.06 years old. Subjects had normal nutritional status (body mass index 20.99 ± 1.65) with mean body weight of 58.13±3.76 kg and mean height of 166.2±3.40 cm. The mean O2max score was 49.56±0.61 mL/kg/min. The mean plasma MDA level was 4.32±2.09 µmol/L. There was no significant correlation between O2max and plasma MDA levels (p=0.7717). In conclusion, training does not negatively impact oxidative stress conditions in student soccer players.

Background: Football as a high-intensity sport that causes fluid loss in the body often makes athletes dehydrated which results in decreased athlete performance. Provision of adequate and appropriate drinks can prevent dehydration. Watermelon rind contains high potassium which can restore lost body fluids.Objectives: Conducted a study to determine the correlation of giving watermelon rind juice to the hydration status of athletes in the Student Football Activity Unit.Methods: The study was conducted with a quasi-experimental design with a pre-posttest without control group design. A sample of 18 soccer athletes was taken using a purposive sampling technique. Subjects were given 300 ml of watermelon rind juice for 7 days. Hydration status was obtained based on the results of urine specific gravity examination. Measurement of hydration status wasconductedbefore and after the intervention period. The research instruments were urine samples analyzed in the laboratory, SOPs for making watermelon rind juice, observation sheets for giving juice, SOPs for measuring hydration status, and hydration status observation sheets. Data analysis using Wilcoxon test.Results: Specific gravity of pretest urine obtained a median of 1.025 g/dl (min-max 1.005-1.030 g/dl). Posttest urine specific gravity received a median of 1.025 g/dl (min-max 1.010-1.031 g/dl). There was an average decrease in urine specific gravity of 0.0019 g/dl at the posttest. The results of the pretest and posttest bivariate analysis obtained a p-value of 0.391.Conclusion: There is no significant effect of watermelon rind juice on the hydration status of athletes in the Student Football Activity Unit. There is a decrease in the average specific gravity of urine after being given watermelon rind juice

Background: Stress during the match can influence the change of mood and performance of athletes. Physical exercise can improve the ability of physiologically and psychologically, but lead to fatigue, dehydration and hypoglycemia. Maltodextrin has a lower osmolarity to improve emotional and performance. Vitamin C as a cofactor of neurotransmitters can support the performance of athletes.Objective: This study aimed to determine the effectiveness of a combination drinks of maltodextrin and vitamin C on mood and the correlation with VO2 max of football athletes.Method: This research is a quasi experimental with same subject design. The subjects were 14 University state of Yogyakarta football athlete. Subjects received a drink of 15% maltodextrin and 250 mg of vitamin C in 300 ml given 30 minutes before and 5 minutes after the performance test using yo-yo intermittent test continued by physical exercise. Measurement of mood would be done in 3 times; before cardiorespiratory test, 5 minutes after physical exercise, and 15 minutes after drink.Results: There are significant changes after consuming a combination of maltodextrin and vitamin C on the confusion (p<0.05), while components of anger, fatigue, depression, tension and vigor (p>0.05). There are significant changes after consuming plain water on fatigue and tension (p<0.05), while anger, confusion, depression, and vigor (p>0.05). There are no significant differences in every components of mood between two treatments. There is a correlation between anger and confusion with cardiorespiratory after consuming a combination of maltodextrin and vitamin C.Conclusion: Maltodextrin and vitamin C has the potential effect to improve the mood condition and have a correlation with VO2 Max improvement in football athletes.

Latar Belakang: Performa atlet merupakan salah satu penentu dalam pencapaian prestasi yang dapat dilihat dari tingkat kebugaran jasmani. Latihan fisik secara teratur memberikan banyak manfaat, tetapi latihan fisik berat dapat memberikan pengaruh  negatif  pada  peningkatan  radikal bebas sehingga menyebabkan  terjadinya stres oksidatif yang berdampak pada performa atlet. Jamur tiram putih (Pluerotus ostreatus) adalah salah satu bahan makanan yang mengandung berbagai macam zat gizi dan antioksidan yang dapat memperbaiki stres oksidatif dan mendukung performa atlet sepak bola. Tujuan: Untuk mengetahui pengaruh pemberian jus jamur tiram putih (Pleurotus ostreatus) terhadap kadar malondialdehid (MDA) pada atlet sepak bola. Metode: Penelitian ini adalah penelitian quasi experimental dengan rancangan pre-posttest without control group. Penelitian dilaksanakan pada bulan September 2017–April 2018 di Lapangan Tamantirta, Klub Guntur FC, Kabupaten Bantul, Daerah Istimewa Yogyakarta. Subjek penelitian adalah delapan atlet sepak bola dari Klub Guntur FC yang memenuhi kriteria inklusi dan ekslusi. Subjek dipilih melalui purposive sampling. Pemberian 300 ml jus jamur tiram putih dilakukan selama 14 hari, atlet diukur kadar MDA sebelum dan sesudah intervensi. Pengukuran kadar MDA dilakukan dengan metode asam thiobarbiturat (TBA). Analisis data menggunakan software statistik dengan Paired T-test. Hasil: Hasil pengukuran kadar MDA pada atlet sepak bola sebelum pemberian jus jamur tiram putih dan setelah pemberian jus jamur tiram putih adalah 5,981±3,150 μmol/l dan 4,019±2,179 μmol/l. Tidak ada perbedaan signifikan pada kadar MDA atlet sepak bola antara sebelum dan sesudah pemberian jus jamur tiram putih (Pleurotus ostreatus) (p>0,05). Kesimpulan: Konsumsi jus jamur tiram putih tidak berpengaruh terhadap kadar MDA atlet sepak bola.
