Abstract

Background Sodium bicarbonate (NaHCO₃) has gained substantial attention as an ergogenic aid due to its buffering capacity, which helps mitigate exercise-induced metabolic acidosis. Its use has been widely explored in high-intensity sports where the accumulation of hydrogen ions contributes to early muscle fatigue and decreased performance. Objectives This systematic review aims to synthesize current empirical evidence regarding the effectiveness of sodium bicarbonate supplementation in enhancing endurance-related performance outcomes, with a particular focus on its role in delaying muscle fatigue during exercise. Methods A Systematic Literature Review (SLR) was conducted following the PRISMA guidelines. Article identification and selection employed the PICO framework. Relevant studies were retrieved from Scopus, ScienceDirect, Web of Science, and PubMed using the keywords “sodium bicarbonate,” “endurance,” “performance,” and “muscle fatigue.” Nine peer-reviewed studies met the inclusion criteria and were analyzed descriptively to evaluate the effects of sodium bicarbonate on athletic performance. Results The findings indicate that sodium bicarbonate supplementation can enhance performance, particularly in high-intensity and short-to-medium-duration activities. However, its effectiveness is highly context-dependent and influenced by exercise modality, duration and intensity, athlete training status, and supplementation protocol—including dosage, timing, and individual physiological tolerance. Several studies employed relatively small and homogeneous samples, limiting the generalizability of the results. Conclusion Sodium bicarbonate shows consistent potential as an ergogenic supplement for improving endurance-related performance by attenuating metabolic fatigue. Nonetheless, its benefits are not uniform across all athletes or sport types. Optimal outcomes appear to require individualized dosing strategies and sport-specific application. This review provides an updated synthesis of evidence on sodium bicarbonate supplementation and highlights critical variables that moderate its effectiveness. The study underscores the need for individualized supplementation protocols and encourages future research employing larger, more diverse athlete populations and standardized ergogenic assessment methods.

Abstract

Background Education in the 21st century demands a paradigm shift from merely transferring knowledge to shaping individuals who are intellectually, emotionally, and socially competent. Schools are not only places where educational processes occur, but also where learning takes place. However, many schools still focus more on academic achievement than on non-academic values, which often leads to the neglect of character education such as students’ discipline, which is beginning to decline. Objectives This article aims to examine the role of pencak silat as an extracurricular activity in addressing the challenges of 21st-century education through a literature review approach. Methods The research method used in this study is a literature review, which is conducted by collecting, reading, examining, and analyzing various sources of literature relevant to the topic or issue being studied. Results Pencak silat, as a cultural heritage of the nation, holds great potential in character building and the development of students’ soft skills. Based on a review of various literature, it is found that pencak silat not only contributes to physical development but also instills values such as discipline, responsibility, cooperation, and nationalism. This article recommends that pencak silat be optimally utilized as part of a holistic character education strategy. The six articles used as references indicate that pencak silat is not merely a physical activity, but also a form of teaching that can significantly contribute to the development of students’ values and character. Conclusion Based on the review of the six articles above, it can be concluded that Pencak Silat contains elements of character education such as discipline, responsibility, and respect. Regular training in Pencak Silat instills perseverance and a strong fighting spirit. In addition, through social interaction in group training, students learn to cooperate and appreciate differences. Moreover, 21st-century education demands the mastery of soft skills. In Pencak Silat, students are trained to focus, think strategically, and manage their emotions. These values are highly relevant to the demands of today’s workforce and the complexities of social life. As an extracurricular activity, Pencak Silat plays a strategic role in addressing the challenges of 21st-century education. Through a literature-based approach, it is found that Pencak Silat not only supports the development of students’ character and soft skills, but also strengthens the nation's cultural identity.
