Abstract

Background: Football is a sport that combines aerobic and anaerobic endurance during training and matches. Physical fitness can support blood circulation function and heart work and increase muscle strength, speed, agility, and explosiveness. Muscle fatigue can be affected by various internal and external factors, including physiological, nutritional, exercise, psychological, environmental, and health factors. One of the nutritional factors that can affect muscle fatigue is micronutrients such as potassium. Potassium and vitamin C deficiency can lead to muscle weakness and fatigue. Objective: The purpose of this study is to determine the difference in the effect of giving isotonic drinks and sweet orange juice on the fatigue level of North Sumatra PPLP football athletes. Method: The research design is true experimental, with the post-test only with a control group design. The subjects consisted of 24 athletes who were selected using systematic random sampling. The level of fatigue is known through the RAST test. Bivariate analysis uses an independent sample t-test to determine the difference in influence between each variable. Results: As a result of this study, there was a significant difference in fatigue levels in the two groups. The average fatigue level value in the treatment group was 4.61±1.42, while the control group was 6.62±2.33 or the Sig. p<0.05 value was p = 0.01. Conclusion: This showed a significant difference in the mean level of athlete fatigue between the treatment group and the control group.

Abstract

Underweight is when a child's weight is below the average range for their age group. The prevalence of underweight toddlers in Indonesia in 2023 reached 12.9%. Underweight is directly caused by food intake. This study aims to determine the relationship between macronutrient intake and the incidence of underweight in toddlers at Posyandu Bangun Sari Indah 6. This research method uses a cross-sectional research design. The population in this study consisted of toddlers aged> 6-59 months, with a total of 135 toddlers. The technique for selecting research subjects used a purposive sample of 48 toddlers. Data collection of food intake used a 2x24-hour food recall form, and underweight data used anthropometric measurements of BB/U. The data analysis technique was descriptive, using the Spearman rank correlation test and the logistic regression test. The results showed a relationship between energy intake (p = 0.003), carbohydrate intake (p = 0.004), protein intake (p = 0.005), and fat intake (p = 0.025) with the incidence of underweight in toddlers. The logistic regression test analysis showed that energy, carbohydrate, protein, and fat intake were not significantly related to the incidence of underweight.
