Reduced functional physical performance capacity (FPPC) is one of the complications patients with type 2 diabetes (T2D) mellitus suffer. The purpose of this study was to investigate the relationship of age, muscle strength (MS) and body composition (BC) parameters of patients with (T2D) with their physical functional capacity. Sixty- two (62) adult patients with T2D comprising 32 males and 30 females, with age ranged between 30- 65 years and have been diagnosed for at least 2 years duration participated in the study. Participants were those purposively selected from endocrine patients without any other physician diagnosed health problem. The FPPC of the participants were measured using the validated Short Physical Performance Battery. All the data collected were fed into SPSS software package for statistical analyses. Mean and standard deviation were obtained and the Pearsonís Product Moment Correlation co-efficient was used to test the hypothesis at 0.05 significant level. The results showed an insignificant correlation between extremities MS and flexibility, BC parameters of body weight, percentage fat per height and body mass index; and FPPC in patients with T2D mellitus. The study therefore concludes that age, more than MS and BC parameters is more linked to FPPC in with T2D patients.
