Metabolic Effects Of Caffeine Ingestion And Physical Work In 75-year Old Citizens. A Randomized, Double-blind, Placebo-controlled, Cross-over Study
Notes for this study:
|Number of Subjects
Persons over 70 were recruited to consume 6mg/kg bodyweight caffeine prior to an hour long cycling endurance exercise.
Insulin resistance increased (ie. sensitivity decreased) due to a conversion of metabolic substrate towards fatty acids; increases in free fatty acids, adrenaline and noradrenaline, and lactate were significantly more than placebo.
