OBJECTIVE: To investigate the effects of a 6-week indoor hand-bike exercise
program on fasting insulin and homeostasis model assessment of insulin resistance
(HOMA-IR) levels and physical fitness in people with spinal cord injury (SCI).
DESIGN: Randomized controlled trial. SETTING: National rehabilitation center
(outpatient). PARTICIPANTS: Participants with SCI
(N=15; exercise group: n=8,
control group: n=7). INTERVENTIONS: This study involved 60-minute exercise
sessions on an indoor hand-bike. Participants in the exercise group exercised 3
times per week for 6 weeks. MAIN OUTCOME MEASURES: Health parameters (body mass
index [BMI], waist circumference, percent body fat, insulin level, and HOMA-IR
level) and fitness outcomes (peak oxygen consumption [Vo2peak], shoulder
abduction and adduction, shoulder flexion and extension, and elbow flexion and
extension). RESULTS: Participation in a 6-week exercise program using an indoor
hand-bike significantly decreased BMI
(baseline: 22.0+/-3.7 m/kg(2) vs
postintervention: 21.7+/-3.5 m/kg(2), P=.028), fasting insulin (baseline:
5.4+/-2.9 muU/mL vs postintervention: 3.4+/-1.5 muU/mL, P=.036), and HOMA-IR
(baseline: 1.0+/-0.6 vs postintervention: 0.6+/-0.3, P=.03) levels compared with
those in the control group. Furthermore, this training program significantly
increased Vo2peak and strength in shoulder abduction, adduction, flexion, and
extension and elbow flexion and extension compared with those in the control
group. CONCLUSIONS:
Exercise using an indoor hand-bike appears to be an effective
modality to improve body composition, fasting insulin, and HOMA-IR levels and
fitness in people with an SCI.
