Trial Outcomes & Findings for High Intensity Interval Exercise SCI (NCT NCT04940598)

NCT ID: NCT04940598

Last Updated: 2024-07-24

Results Overview

All subjects will undergo a progressive peak oxygen assessment to determine aerobic capacity at the Lakeshore Foundation Exercise Physiology Facility. Subjects will be instructed to perform arm crank ergometer (Lode) at 10W for 2 min. Every 2 min thereafter, power output will be increased by 10W until voluntary fatigue. Peak aerobic power will be defined as VO2 at the point of failure to maintain 60-65 rotations per minute.

Participant Flow

Potential participants were identified by a computer-generated list of patients who are enrolled in the UAB SCI Model System and the Lakeshore Foundation Member Database and currently reside in the greater Birmingham, Alabama area. All potential participants were mailed a letter which describes the study, invites them to participate. Additional recruiting was done by posting fliers at the UAB Spain Rehabilitation Center (SRC) and Lakeshore Foundation.

Measure
High Intensity Interval Exercise
High intensity interval arm crank exercise 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.

Oral glucose tolerance test. Following an overnight fast each subject will consume a 75g oral glucose load within 5 min. Blood samples will be collected immediately before and 60, 90, and 120 min following glucose ingestion for measurement of serum glucose and serum insulin. Insulin sensitivity was calculated using glucose and insulin values by the Matsuda Index, in which a higher number demonstrates an improvement in insulin sensitivity,
