Abstract

Background: The health conditions of the community, particularly in relation to the physical fitness of junior high school students, require serious attention, especially in rural areas that differ significantly from urban areas. Previous research findings on dietary patterns and physical fitness still show inconsistent results. Objectives: This study aims to investigate the relationship between healthy eating habits and physical fitness among junior high school students residing in rural areas. Methods: This study used a quantitative design with a cross-sectional approach. The research subjects consisted of 27 students from public junior high schools in rural areas, selected through a balanced stratified random sampling process that involved all grade levels. Eating habits were measured using a 24-hour food recall, as it is an effective method for monitoring food intake over a short period. Physical fitness was measured using the Nusantara Student Fitness Test (TKPN), a national standard instrument. Data analysis was performed using descriptive statistics, Spearman's correlation, and linear regression. Results: Most of the study participants were underweight with varied eating patterns. The analysis results showed no significant relationship between physical fitness and healthy eating patterns, as indicated by a correlation coefficient of 0.061 and a p-value of 0.764. The small effect size suggests that eating patterns did not have a significant impact on fitness levels in this group of participants. Conclusions: The study shows that rural junior high school students achieve their physical fitness through exercise and their exercise-rest patterns and their inherited characteristics rather than their diet.

Abstract

Caffeine is one of the most widely consumed ergogenic substances worldwide, with an average daily intake among adults ranging from approximately 100–200 mg/day. In sports contexts, caffeine is commonly used at doses of around 3–6 mg/kg body weight to enhance athletic performance. However, most research on the ergogenic effects of caffeine has primarily focused on male or mixed populations, despite evidence that physiological and hormonal differences may influence female athletes’ responses to caffeine supplementation. This study aimed to systematically review current scientific evidence regarding the effects of caffeine supplementation on the physical and psychophysiological performance of elite female athletes. This study employed a systematic review design in accordance with the PRISMA 2020 guidelines. Literature searches were conducted in the PubMed and Scopus databases for publications from 2016 to 2025. Inclusion criteria were determined using the PICOS framework, focusing on controlled experimental studies involving elite female athletes. Of the 2,254 articles identified, nine studies met the inclusion criteria and were analyzed qualitatively. Most studies used randomized, double-blind, placebo-controlled crossover designs and reported that caffeine supplementation at doses of 2.3–6 mg/kg body weight improved strength, speed, cognitive response, and exercise enjoyment. However, the results were not always consistent, particularly among athletes with high habitual caffeine intake or when lower doses were administered. In conclusion, caffeine may enhance the performance of elite female athletes. Nevertheless, the existing literature presents several limitations, including the limited number of studies, small sample sizes, and variability in study design, caffeine dosage, and control of hormonal factors such as the menstrual cycle. Therefore, caffeine use in female athletes requires a more individualized and gender-specific supplementation approach.
