Brief Summary

The consumption of energy drinks has significantly increased in recent years but their adverse effects are not yet efficiently known. The objective of the study is to determine the acute effects of energy drink on habitual and non-habitual caffeine consumers and if caffeine consumption habit causes a difference on the hemodynamic and electrophysiologic parameters. This study was conducted on 48 students selected from Aydın Adnan Menderes University. Four main groups were determined according to the results of the application acceptance survey. Blood pressure, electrocardiogram, breath rate, haemoglobin oxygen saturation and bioelectrical impedance analysis were measured before consuming the drinks. After consuming the drinks, measurements were repeated at 30 minutes and 60 minutes. In addition to this, Participant's Situation Anxiety Scale was applied.

Model Details: The individuals were identified by collecting the age, weight, height, BMI, caffeine and energy drink consumption habit information by applicant acceptance questionnaire. Based on the applicant acceptance questionnaire 12 subjects were low-habitual caffeine consumers with an estimated daily intake of approximately 130 mg caffeine and named as energy drink 2 (ED2) group, 12 subjects were high-habitual caffeine consumers with an estimated daily intake of approximately more than 200 mg caffeine and named as energy drink 3 (ED3) group, while 24 subjects were caffeine naive (energy drink 1 (ED1) (n=12) and Control (n=12)) .
