Abstract
ABSTRACT. Caffeine, a widely consumed drug, has been shown to significantly increase heart rate (HR) and blood pressure (Geethavani et al., 2014), but had only insignificant changes in these cardiovascular measurements (Alhabeeb et al., 2022); while Matsumara and his colleagues (2023) reported that caffeine decreased 100-meter sprint times indicating that caffeine may improve anaerobic performance. The current study investigated the short-term effects of caffeine on heart rate (HR, beats per minute), blood pressure (mmHg), and 20-yard sprint performance time (seconds; Dashr Sprint Timing System). These parameters were measured in triplicate before and at 45-minutes after caffeine supplementation at a dose of 4 mg/kg among ten male collegiate athletes aged 18-22. Based on this study, a trend was observed in that the percent change for mean arterial pressure (MAP, 13%) and diastolic blood pressure (DBP, 19%) increased post-caffeine supplementation among non-habitual caffeine drinkers, however, these were not significantly different from those of habitual caffeine consumers. Overall, regardless of caffeine intake behavior, results demonstrated that while caffeine significantly increased both systolic blood pressure (SBP) (p = 0.008) and MAP (p = 0.0185) levels, it did not significantly decrease sprint speed (p = 0.397) indicating lack of improvement in anaerobic strength output due to caffeine supplementation.
