The study investigated the effect of caffeine on physical performance in healthy citizens aged over 70 years. The main hypothesis was that 6 mg/kg caffeine would improve cycling endurance at 65% of expected maximal heart rate.

Official Title: | The Effect of Caffeine as Endurance Enhancing Drug in the Elderly |
Estimated Enrollment: | 30 |
Study Start Date: | July 2002 |
Estimated Study Completion Date: | March 2006 |
Caffeine ingestion increases the endurance of young people exercising at 60%-85% of their maximal oxygen uptake, and it also seems to improve endurance as measured by repeated sub-maximal isometric contraction and decreases the rate of perceived exertion during exercise. Although caffeine increases endurance in young people, an increase in endurance may be of greater interest in the elderly as the population of older adults with a physically active lifestyle is growing rapidly or for increasing endurance fitness through an exercise or rehabilitation program. Therefore the main hypothesis was that caffeine would improve cycling endurance at 65% of expected maximal heart rate, and the secondary hypotheses were that caffeine would improve postural stability, reaction and movement times, isometric arm flexion endurance, and walking speed, and would reduce the rate of perceived exertion after 5 minutes of cycling in healthy elderly citizens.
