Abstract

Caffeine is a widely used ergogenic aid known to enhance both physical and cognitive performance. Its potential to influence lactate accumulation during high-intensity exercise, such as sprinting, remains an area of interest.This study aimed to investigate the effect of 100% Arabica caffeine consumption on blood lactate levels following sprint activity.Using a pretest-posttest control group design, 32 sprint athletes from KONI Madiun (divided into treatment and control groups) participated in a 30-meter sprint test repeated three times. The treatment group consumed 3–6 mg/kg body weight of caffeine in the form of an Americano one hour prior to testing. Blood lactate levels were measured post-sprint using a lactate analyzer. Independent t-tests were conducted with a significance level of p < 0.05. The treatment group consistently exhibited lower lactate levels compared to the control group across all sprint stages. Statistically significant differences were observed in Sprint 1, Sprint 2, and the total lactate accumulation while Sprint 3 showed no significant difference (p = 0.072). The findings suggest that caffeine consumption before sprinting may reduce lactate accumulation and improve metabolic efficiency. Caffeine intake in the form of 100% Arabica Americano has a significant effect in lowering blood lactate levels during repeated high-intensity sprint efforts. This supports its potential use as an ergogenic aid in anaerobic sports. However, variability in individual response highlights the need for tailored supplementation strategies and further investigation into long-term physiological adaptations.

Abstract

This study aims to examine the effect of listening to dangdut music on dopamine secretion among full-day school students. The research addresses the core issue of how musical stimuli, particularly within a cultural context, can influence neurochemical responses linked to emotional well-being. Employing a posttest-only control group design, the study involved 30 high school students randomly assigned into two equal groups: the experimental group listened to dangdut music of their choice for 15 minutes, while the control group engaged in non-musical activities. Urine samples were collected immediately after treatment and analyzed in a laboratory to measure dopamine levels. Data were statistically processed using an independent t-test. Results showed a significant difference in dopamine secretion between the two groups: the experimental group had a mean dopamine level of 53.60 ng/mL (SD = 3.95), while the control group had 30.93 ng/mL (SD = 2.01), with a t-value of 19.81 (p < 0.05). These findings indicate that listening to dangdut music significantly enhances dopamine release, supporting the hypothesis that music serves as a positive neuropsychological stimulus. The study concludes that incorporating culturally relevant music into the school environment can be a simple, cost-effective intervention to improve students' emotional well-being and academic engagement. This research contributes to the growing field of music psychology by emphasizing the role of local music genres in promoting mental health within educational settings.
