Aging is a process of various changes precipitated overtime which increases the risk of diseases and death. The diversity of changes simultaneously follows the age advancement. Since the Fullerton functional fitness test has been developed and performed in different countries, this is to assess a Reliability and Validity of Fullerton Functional Fitness test in the community dwelling elderly aged between 50-70 years of the Indian population. These include information of the study design, the source, the subjects, instrumentation, procedure of assessment and methods used in data collection. Study design - Reliability and Validity of Battery Test Sample: Adults age between 50 -70 years, Sample source: community dwelling elderly, Sample size: 80. The Fullerton test encompasses six items for assessment of Aerobic endurance, Upper body strength, Lower body strength, Motor Coordination and Balance. Before the commencement of the test, the subject will be instructed to perform the tasks accurately. Proper positioning of the devices should be ensured for safety purposes. A five- to ten-minute warm-up exercises along with general stretching exercises will be performed before the tests commences. Before beginning and after the tests are finished, heart rate and arterial blood pressure will be measured. The first test will be forearm flexion - arm curl followed by the back scratch, rising from chair, chair sit and reach, the 8 feet trial and 2 min step-in-place. Informed Consent taken 1.DAY 1 - FFT + TIME UP AND GO (TUG) + BRIEF BEST 2.DAY 2 - FFT + 6 MIN WALK TEST (ATS guidelines 2002) 3.DAY 3 - FFT and then final scores are taken scores of FFT. The protocol of day 1,2, and 3 will be used for reliability and scores of FFT, TUG, Brief best, 6MWT will be used for validity. A total number of 76 subjects were assessed for the study. According to inclusion and exclusion criteria, the subjects aged 50-70 year have been enrolled in the study, out of which 26 were female subjects and 50 were male subjects. The age group of 50 - 60 years of 27 male and 18 female with mean age 55.66±3.44 and 55.00±3.12 and another group of age 61-70 years of 23 male and 7 female with mean age 67.30±3.52 and 67.42±3.50.The age group of 50 - 60 years of 27 male and 18 female with mean BMI 24.91±3.19 and 26.38±3.40 and another group of age 61-70 years of 23 male and 7 female with mean BMI 25.38±3.25 and 25.42±1.69. In summary, although the relative reliability for all the test items are acceptable. The result shows a significant correlation. This tool is highly reliable and valid in the Indian population
