Nutritional Strategies for Enhancing Endurance, Recovery, and Metabolic Efficiency in Athletes in Palu City, Indonesia

Abstract

Objectives: This study aimed to examine the effectiveness of nutritional strategies in enhancing endurance, recovery, and metabolic efficiency among athletes in Palu City, Indonesia.

Materials and Methods: This study used a quantitative experimental approach with a pretest–posttest design. A total of 40 athletes from various sports disciplines participated in an eight-week structured nutritional intervention program. The intervention consisted of carbohydrate periodization, protein optimization, and hydration strategies. Data were collected using VO₂max testing, blood lactate analysis, and recovery rate measurements. Data were analyzed by comparing pretest and posttest results, with the significance level set at p < 0.05.

Results: The results showed significant improvements in endurance after the nutritional intervention, as indicated by increased VO₂max scores. Participants also demonstrated faster recovery rates and improved metabolic efficiency, supported by more favorable blood lactate responses after exercise. These findings indicate that structured nutritional strategies contributed positively to endurance capacity, recovery optimization, and metabolic regulation among athletes.

Conclusions: Structured nutritional strategies are effective in improving endurance, recovery, and metabolic efficiency among athletes in Palu City. The integration of carbohydrate periodization, protein optimization, and hydration planning can support better athletic performance and recovery management. These findings provide practical implications for coaches, athletes, and sports nutritionists in developing evidence-based nutrition programs in regional training contexts.
