The purpose of the present study was to evaluate the ergogenic effect of caffeine on elite judo players' mood states, simple reaction time, and muscle power during the Wingate test in the afternoon. 10 elite judo players (age: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height:1.76 ± 6.57 m) participated in this study. The performance variables were measured during two test sessions at 17:00 h: after placebo or caffeine (5 mg.kg -1 ) ingestion. Results revealed an increase in anxiety and vigor (p<0.05) and a reduction in simple reaction time (p<0.005) following caffeine ingestion. However, muscle power and fatigue during the Wingate test Downloaded by [Anadolu University] at 07:31 22 December 2014were unaffected. It is concluded that afternoon caffeine ingestion has no ergogenic effect on anaerobic performance.

Regular exercise is one of the most used solutions to avoid obesity. In this study we compared the amounts of lipid oxidation and the level of perceived exertion in three physical exercises, one continuous and two intermittent in obese. Ten obese men (age 26.01 ± 6.0 years, weight: 104.2 ± 19.4 kg, BMI: 33.5 ± 3.6 kg / m 2 ) performed three 45 minutes exercises during which we measured energy expenditure and the level of perceived exertion.
