The proposed study will examine the feasibility and effectiveness of a high intensity functional training (HIFT) pilot study for adults with mobility-related disabilities (MRD).~Aim 1 will explore the feasibility of a 12-week, thrice weekly HIFT intervention for adults with MRD. Investigators will evaluate participant acceptability and satisfaction, document recruitment challenges, attrition rates, and the adaptive elements of the program for replication and improvement to future clinical trials. Aim 2 will assess the effects of HIFT participation on participant health outcomes, including (i) fitness factors such as work capacity, strength, and energy expenditure; (ii) functional performance; (iii) body composition and weight; and (iv) variables contributing to psychological well-being such as motivation, quality of life, and life satisfaction.~A relatively novel mode of exercise, HIFT stands out for its inclusive approach and adaptable programming, which has the potential to improve health outcomes for a novel target population. The proposed research activities will provide initial data on the feasibility and expected magnitude of change in multiple dimensions of health for people with MRD and contribute to the limited evidence of community-based programs that are adaptable and inclusive. The findings will also allow for the mobilization of this knowledge into disability and healthcare communities to increase the recommendations for exercise for this population and inform future design of clinical trials.
Investigators will examine the feasibility and health outcomes following a high-intensity functional training intervention for people with mobility-related disabilities. In addition to participant recruitment, attritions rates, and satisfaction, investigators will assess changes to both physical health outcomes (e.g., strength, body composition) and psychosocial outcomes (e.g., quality of life). The findings will provide evidence for the efficacy of HIFT to improve various health outcomes for a population that experiences health disparities in access to, and engagement in, community-based exercise.
