Introduction
In pharmacology, caffeine is a psychoactive compound that boasts a venerable history of human consumption and encompasses individuals of various ethnic backgrounds. Its incorporation into consumables and potables, such as chocolate, carbonated beverages, coffee, sports drinks, and black and green tea, has left an indelible mark on human culinary traditions. Notably, caffeine has also found a place within the domain of pharmacotherapeutics, featuring as an active constituent in over-the-counter medications such as Excedrin, Anacin, and Midol.
Significantly, caffeine has transcended its role as a mere stimulant and emerged as a noteworthy agent in athletics and physical training. Coaches, athletes, and recreational practitioners have recognized its potential for augmenting performance, attributing its salutary effects to aerobic and anaerobic exercise scenarios. Forman et al. (1995) have asseverated that 70% of youthful athletes worldwide incorporate caffeine into their regimens. An array of scholarly inquiries has illuminated the nexus between caffeine administration, particularly at a dosage approximating 3 mg/kg, and the amelioration of athletic performance (Jenkins et al., 2008; Ivy et al., 1979; Kovacs et al., 1998; Bridge & Jones, 2006).
Nonetheless, the precise explication of caffeine's ergogenic effect and its mechanistic underpinnings remains an enigma that has yet to yield scholarly scrutiny. Caffeine intake has been linked to heightened epinephrine secretion (Graham et al., 1995; Greer et al., 1998). Researchers have also propounded theories concerning caffeine's impact on endurance pursuits, positing that it engenders increased lipid utilization while conserving muscle glycogen stores (Costill et al., 1978). Nevertheless, Graham et al. (2000) have proffered a counterargument, asserting that caffeine does not appreciably elevate fat metabolism. On an alternative front, Kalmar and Cafarelli (1999) have explicated the modus operandi of caffeine in the context of strength exercises, postulating
