Results indicated a significant improvement in sprint time for the first three sprints, with a consequential increase in fatigue for the caffeine condition [ 31 ].

The results indicated caffeine supplementation significantly increased erhenic time to exhaustion regardless of whether caffeine etgenic anhydrous form was consumed after a cup of regular or decaffeinated coffee [ 27 ].
