The structural appearance of each disabled athlete or the shape of their body, as determined by their individual genotype and influenced by the environment, considerably affects their technical and physical performance. This study sought to examine the morphological characteristics of elite track and field athletes with different disabilities, including their possible effects on physical and physiological performance. A total of 66 male elite athletes with cerebral palsy (n = 12), upper arm amputation (n = 12), short stature (n = 20), or intellectual disability (n = 22) were included. For each athlete, height, weight, sitting height, arm span and four skin folds were assessed; ape index, body mass index, body fat percentage, fat mass, fat mass index and fat-free mass values were calculated; and vertical jump, drop jump, countermovement jump, squat jump, repeated sprint ability and Yo-Yo Intermittent Recovery Level 1 tests were performed. Significant differences were noticed between short stature and the other groups concerning morphological characteristics, however, the best motor performance was observed in amputees and, to a lesser degree, in short stature. In the top performing athletes, physical performance was significantly correlated with body mass index and fat mass index for amputees, and with arm span, ape index, body fat percentage and fat mass index for short stature. Regression analysis revealed that regardless of disability type, physical and physiological performance (except maximum heart rate) were significantly influenced primarily by adipose tissue-specific variables. A significant effect of height, weight, fat free mass, arm span, sitting height, and ape index on drop jump performance with left leg, maximal oxygen consumption, and maximum heart rate was also noticed. The type of disability affects performance in the squat jump and vertical jump tests, and to a lesser extent in the countermovement jump test.
