The effects of resistance exercise on insulin sensitivity in adolescents
Sarah Critch
Memorial University of Newfoundland, Canada
A
n escalating incidence of type 2 diabetes among adolescents is thought to be sparked by rising population-wide prevalence
of insulin resistance. Resistance exercise has been shown to reduce insulin resistance, however only immediate, post-
intervention effects have been demonstrated. The purpose of this study was to assess the effects, up to six months, of resistance
exercise on insulin sensitivity, cardiorespiratory fitness, muscle strength, activity levels, and anthropometric measures
among adolescents with insulin resistance. Participants, recruited from a chronic disease prevention program, completed a
physiotherapist-supervised 10-week resistance exercise program, 60-minutes, three times per week. A body positive approach
was used focusing on health behaviours. Using a repeated-measures design, participants were assessed during a control period
then at pre, post, and 6-month follow-up assessments.The primary outcome was insulin sensitivity, measured by the oral glucose
tolerance test. Secondary outcomes included cardiorespiratory fitness, muscle strength, activity level, and anthropometric
measures. Thirteen participants (14.16±1.19 years old; 8 males,5 females) completed the intervention. Improvements in insulin
sensitivity were found, observed as reduced fasting insulin [F(2,22)=7.54, p=0.003, ηp2=0.41], fasting glucose [F(2,22)=3.58,
p=0.045, ηp2=0.25], andHOMA-IR [F(2,22)=7.60, p=0.003, ηp2=0.41], which were maintained at follow-up. Cardiorespiratory
fitness, waist circumference, and waist-to-hip ratio significantly improved at post and follow-up. The findings suggest that a
supervised 10-week resistance exercise program improves insulin sensitivity, cardiorespiratory fitness, waist circumference, and
waist-to-hip ratio in adolescents who are at high risk of developing type 2 diabetes. Importantly, these benefits are maintained
up to six months. Supervised, resistance exercise adds significant long-term benefit in the management of insulin resistance in
adolescents.
