Dari tahun ke tahun konsumsi Sugar-Sweetened Beverages atau minuman dengan tambahan gula (SSB) di Indonesia terus mengalami peningkatan. Hal ini dapat memicu peningkatan berat badan dan berisiko terjadinya obesitas. Remaja usia sekolah mulai mengalami peningkatan selera makan namun tidak diikuti dengan aktivitas fisik yang cukup sehingga dapat menimbulkan risiko terjadinya obesitas. Status gizi pada remaja akan menyebabkan perubahan status gizi di masa dewasa. Obesitas menjadi salah satu faktor pemicu penyakit-penyakit berisiko. Kegiatan pendampingan berupa pendidikan kesehatan dilaksanakan dengan menggunakan metode ceramah dan diskusi. Pada proses pendidikan kesehatan, para siswa diberikan kesempatan untuk berdiskusi tentang risiko konsumsi tinggi SSB dan obesitas. Materi pendidikan kesehatan yang diberikan adalah mencakup bidang gizi dan farmasi. Pendampingan remaja dengan pendidikan kesehatan ini dapat menjadi salah satu upaya dalam pencegahan obesitas pada remaja. Selain itu, pendidikan kesehatan yang berisi tentang pemilihan makanan dan minuman yang sesuai dengan gizi seimbang, aktivitas fisik untuk remaja, serta risiko konsumsi tinggi SSB dan obesitas dapat meningkatkan pengetahuan, menurunkan tingkat konsumsi SSB, serta meningkatkan kesadaran akan pentingnya gizi seimbang dalam upaya pencegahan terjadinya obesitas.

Introduction: The response of lactic acid as a result of exercise in recent times has received considerable attention from physiologists, particularly in term of sports aspect. Lactic acid level is one of the most common measured parameter to determine the performance of athletes. Provision of supplements containing potassium for athletes is usually given such fruit juice or sport drink to prevent muscle fatigue. This study examined the effect of the banana juice and sport drinks to lactic acid in volleyball students.Methods: The study was a randomized experimental trial using pre-post test with control group. The study populations were all volleyball students aged 15-17 years in Pundong Senior High School. The subjects divided into three equal group, 10 subjects in each group treated with either banana juice, sport drink and mineral water as a control group. Sampling was done by a double-blind method.Results: The results of the paired sample T-Test showed a significantly difference of lactic acid levels by intervention with banana juice and sport drink compared to control group with mean difference the mean were 4.43, 3.59, 2.68 respectively (p<0.05).Conclusions: Intervention of banana juice significantly decreased the lactic acid levels compared to sport drinks in volleyball students.

Background: The current era of modernization requires someone to look athletic, one of them is by making muscle mass formation, especially in men. Many things are done to fulfill these desires, including weight training. Weight training is a common type of strength training for developing the strength and size of skeletal muscles. Protein intake is also important for the development of skeletal muscles. This study aimed to examine the relationship of protein intake and intensity of weight training with muscle mass among fitness center members. Subjects and Method: This was a cross sectional study conducted at Victory fitness center, Yogyakarta. A sample of 31 fitness members was selected for this study. The dependent variable was muscle mass. The independent variables were percent of protein intake and intensity of weight training. Muscle mass was measured by midline and skinfold. Percent of protein intake was measured by 24 hour-food recall and the data were analyzed by Nutrition Survey 2008. Intensity of weight training was measured by observation. The data were analyzed by a multiple linear regression. Results: Protein intake was low in 19 (61.29%) subjects. Intensity of weight training was low in 15 (48.3%) subjects. Muscle mass was small in 17 (54.8%) subjects. Muscle mass increased with high percent of protein intake (b= 0.35; p= 0.044) and high intensity of weight training (b= 0.98; p= 0.037). Conclusion: Muscle mass increases with weight training and protein intake among fitness center members.
