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.
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.

A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.
Housing arrangements for the elderly or aged, intended to foster independent living. The housing may take the form of group homes or small apartments. It is available to the economically self-supporting but the concept includes housing for the elderly with some physical limitations. The concept should be differentiated from HOMES FOR THE AGED which is restricted to long-term geriatric facilities providing supervised medical and nursing services.
Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
