Abstract
Introduction: caffeine is a psychoactive compound that boasts a venerable history of human consumption and encompasses individuals of various ethnic backgrounds.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. Athletes, such as short-distance swimmers, who utilize the anaerobic system are interested in taking supplementation to boost their strength. Thus, the purpose of this study was to examine the effects of caffeine supplementation (250 mg) on upper body strength in swimmers’ college students. Methods: twenty-two college age swimmers volunteered for the study. The study design was a randomized double-blind cross-over. This study consisted of two testing sessions. During the first and second testing sessions, subjects were given either coffee with caffeine or placebo. After forty-five minutes, the subjects were then asked to perform isometric hand grip strength. Results:The results show that age mean of the participants was 21 ± 2 years, mean height of 176 ± 7 cm, mean body weight resulted to 84 ± 14.2 kg, and the body mass index concludes 27.1 ± 4.1kg/m2. Moreover, further significant difference was not observed between placebo with a mean of 36.1 ± 3 kg. vs. caffeine mean of 36.7 ± 3.2 kg in the left-hand grip strength for the set p-value Conclusion: In conclusion, our present results indicate that consuming of a coffee, with 250 mg of caffeine was not effective to increase upper body strength in male swimmers.
