Summary

This study will determine if the implementation of a home-based telehealth high intensity interval exercise-training (HIIT)program can significantly improve cardiometabolic health and physical function in a cohort of individuals with longstanding spinal cord injury (SCI). Results from this study will determine feasibility, overall enjoyment, and health impact of implementing a home-based telehealth HIIT program in individuals with SCI.

Detailed description

For individuals with spinal cord injury (SCI), exercise participation reduces the risk of developing chronic cardiometabolic diseases, which are leading causes of rehospitalization and death within this population. Accordingly, recent SCI exercise guidelines have highlighted a need for exercise trials that can improve cardiometabolic factors such as glucose tolerance, blood lipids, blood pressure, and body composition. However, to date, the number of exercise trials examining these cardiometabolic outcomes in SCI is low, and these exercise regimens are often inconvenient for individuals with SCI to perform within their community. In addition to the functional impairment associated with the disability, individuals with SCI experience a number of barriers to exercise participation, such as lack of time (e.g. conflict with work schedule), accessible or usable equipment and facilities, and transportation. Thus, it is important to identify effective modes of exercise that can improve overall health but do not require a significant overall weekly time commitment. Investigators recently demonstrated that individuals with SCI could safely perform high intensity interval training (HIIT) using arm crank cycling and that as few as two days per week of HIIT could improve cardiometabolic health. Despite the advantages of HIIT, it is important to identify methods of implementing exercise trials that can successfully reach and maintain participation in larger cohorts. Recent work by the investigative group demonstrated that individuals with SCI expressed favorable perceptions of home-exercise training that incorporated telehealth technology, which allowed a fitness specialist to remotely monitor participants' training progress in real-time and provide verbal support via videoconferencing. This method of training holds even greater value for home-exercise programs that require monitoring to dose-specific protocols such as HIIT. However, the long-term success of HIIT will greatly depend on the ease at which the program can be implemented, as well as participants' adherence and perceptions of using the technology, which has not been investigated in SCI. The goal of this study is to integrate a home-based telehealth HIIT arm crank exercise training program in individuals with SCI and assess changes in cardiometabolic health and physical function. The secondary goal is to explore the uptake and implementation of HIIT in SCI. 40 participants will be randomized to home-based HIIT exercise or a no-exercise control group for 16-weeks. Body composition, aerobic fitness, muscular strength, and changes in cardiometabolic health will be assessed at baseline and 16-weeks post training. In addition to changes in cardiometabolic health outcomes, the investigators will also conduct interviews with participants to determine overall perceptions of the program, program likes and dislikes, perceived satisfaction and value, usability of equipment and technology, and factors that influence adherence.

Conditions

• Spinal Cord Injuries
• Cardiometabolic Diseases

Interventions

Type	Name	Description
OTHER	high intensity interval exercise	HIIT training will be delivered two times per week for 16 weeks (32 sessions). Each session will be separated by at least 24-hrs. Participants will be allowed to choose the days and times that they feel exercise will fit into their schedule. The HIIT protocol will be determined based on peak anaerobic power measures during an arm crank Wingate Cycle test. HIIT will consist of 20 minutes of exercise consisting of four minutes of arm crank exercise at 5% of peak anaerobic power followed by 30 seconds at 30% of the peak anaerobic power; this cycle will be repeated four times, ending with two minutes of recovery at 5% of peak anaerobic power.
OTHER	No-exercise control group	No-exercise control group
