The purpose of this study was to evaluate the risk of low energy availability (LEA) in a population of active individuals with physical disabilities. Healthy, active males and females with a physical disability (n=13; Mean±SD; Age: 26.4±6.5 years; Height: 143.4±59.6 cm; Body mass: 57.5±27.3 kg; Fat-free mass: 41±20.8 kg;) were recruited to participate in this study. Participants were expected to track their exercise energy expenditure (EEE) and energy intake (EI) over the course of five days using portable wrist and chest-strap heart rate monitors. Body composition assessment completed via dual-energy x-ray absorptiometry (DXA) and resting energy expenditure (REE) performed via indirect calorimetry. Energy availability (EA) was then calculated to assess the subjects’ risk for LEA. The participants’ mean EA values were 26.0 kcal/kg FFM/day showing a low level of EA leftover according to the cutoff values. In conclusion, individuals with physical disabilities who are at least moderately active should be cautious when it comes to their EA each day. There is potential for near sub-optimal EA levels in this population.
