Conclusion Caffeine Is Known To Stimulate The Brai

ConclusionCaffeine is known to stimulate the brain and improve metabolism. Although caffeine is classified as a drug the effects of caffeine ingested through coffee intake is debatable. Through controlled trials, the study proves that coffee and caffeine intake prior to exercise improves body endurance and metabolism. Based on 12 studies and (1–6 mg CAF/kg BW) coffee intake, the study established that metabolic performance was improved by about 3%. On the other hand caffeine intake of 4.9% and 4.5% compared to coffee resulted in improved performance. Both the study and existing literature indicate caffeine and coffee as metabolic stimulants. Intakes of both coffee and caffeine 1 hour before exercise had similar stimulant effects if other variables remained constant. Coffee contains 2% caffeine and mainly chlorogenic acids. Study results suggest that chlorogenic acids do not impair ergogenic effects of coffee. Thus the difference between coffee and caffeine intakes is dependent on mode and intensity of exercise that an individual undertakes. However the study does not establish if small doses of caffeine have similar ergogenic effects as coffee does. Optimal measurement of both effects will be applicable in nutrition strategy for athletes.
