Individual heart rate produced may vary at different time of the day and their food intake. 10 male sprinter athletes (n=IO) from Fox Athletics Club of Universiti Pendidikan Sultan Idris had participated in this study. Participants were divided into two groups, caffeine group (n=5) and control group (n=5) accordingly. Training sessions were conducted with one week interval and sprint training were performed by the sprinters as the exercise load method.
