This study was conducted to investigate the effects of some energy drinks mixture with Flunitrazepam on endurance pattern and cognitomotor activities in male Wistar rats. 45 Wistar rats were divided into 8 groups. Group 1 received distilled water; Group 2 received energy drink (A) (3.75 mg/kg). Group 3 energy drink (A) (7.5 mg/kg) Group 4 received energy drink (B) (3.75 mg/kg). Group 5 energy drink (B) (7.5 mg/kg) Group 6 received flunitrazepam (0.03 ml/kg), Group 7 received 3.75 ml/kg of energy drink (A) and 0.03 ml/kg of flunitrazepam, and Group 8 received 3.75 ml/kg of energy drink (B) and 0.03 ml/kg of flunitrazepam. Administration of the mixture lasted for 28 days while endurance test/Cognitive and motor functions test were conducted weekly using Handgrip test, beam walk test and navigational maze test. The result reveals significant improvement in endurance pattern and cognitomotor functions in groups administered with energy drinks alone at week one, however the mixture of energy drink with various doses of Flunitrazepam showed significant impairment in both endurance pattern, and cognitomotor activities. It was therefore concluded that while the combination of energy drinks and flunitrazepam may offer short-term benefits in terms of endurance, and alertness, there is a dose and time dependent significant decline in cognitive and motor functions functions in wistar rats. The findings suggest significant variations in endurance and cognitive-motor performance across different groups, highlighting the complex interactions between stimulant and sedative substances and their implications for health and behavior.
