Middle-aged women display many physiological and cognitive alterations resulting from aging and physical inactivity as well as other changes that occur as a function of menopause. Caffeine consumption is highest in this age with women having a particular greater sensitivity to caffeine than men. Its effects on functional and cognitive functions are controversial and seem to depend on the dose intake. This study aimed to assess the effect of low (100mg) and high (400mg) doses of caffeine consumption on cognitive (simple reaction time) and functional (upper and low body muscle endurance, aerobic endurance and functional mobility) performances. These performances were evaluated in 19 healthy middle-aged women by the 30-Second Chair Stand test for lower body muscle endurance, the 30sec Arm Curl Test for upper body muscle endurance, the 2-Minute Step test for aerobic endurance, The Timed Up and Go test for functional mobility and the simple reaction time test for reaction time, 60min after a treatment capsule intake (100mg caffeine/400mg caffeine/placebo). Low caffeine consumption significantly improved (p<.005) cognitive performance, while high caffeine consumption did not. However, the functional performance significantly improved (p<.05) after high caffeine consumption but not after low caffeine consumption. Except, the functional mobility performance significantly improved (p<.05) after both low and high caffeine consumption with better improvement (p<.05) after the high dose. In conclusion, low caffeine consumption improved cognitive performance and high caffeine consumption improved functional performance but the functional mobility improved after both low and high caffeine consumption in middle-aged women.
