Benefits of Regular Exercise for Individuals with T1D
PA levels in T1D
Patients with T1D whoa re more sedentary and do less intensity activity have more diabetic complications
(Waden et al., 2008)
How active?
Objective data indicated that children
(Czenczek-Lewandowsk et al., 2019)
with T1D are more sedentary and adults with newly diagnosed T1D engage in less MVPA.
Patients with long-standing T1D reported 63% of patients to be physically inactive
Bohn et al., 2009)
Barriers to exercise in newly diagnosed T1D
(Kennedy et al., 2018)
Although exercise was felt to +vely impact health, some participants were not sure about the benefits or concerned about
potential harms such as hypoglycaemia
.
Some patients reported being
advised by healthcare practitioners not to exericse
An important finding was that around 1/2 of the participants reported a
reduction in activity levels around diagnosis.
PA and Glucose Control in T1D
(Bohn et al., 2015)
This study showed that
active
patients with established disease had
reduced blood glucose (BG) levels
(measured by HbA1c).
Controlling for diet and insulin doses
makes data interpretation challenging.
HbA1c doesn't account for
acute glycaemic complications
Continuous glucose monitoring
is more favorable approach to raise patient awareness of BG levels
(Laffel et al., 2020)
Studies using CGM indicate that certain exercise training modes are safe, but the data is still mixed showing marked improvements in glycaemic control per se
(Scott, 2018)
β-cell preserving effects of exercise
Studies demonstrating benefits of exercise training on β-cell health have largely been undertaken in
individuals in with T2D or animal models.
The effects appear to be detectable following
6-weeks
of exercise training.
Exercise training (DT) in mice preserved
β-cell mass
compared to sedentary controls (DM) and enhanced the amount of
insulin produced per islet
.
Exercise preserves β-cell function in T1D
(Sletz et al., 2009)
3 different exercise training programmes
improved β-cell function
in obese T1D adults over 8 months vs. control group.
After glucose tolerance test, calculating the Di represents:
The ability of the pancreas to
secrete insulin
The
sensitivity
of
tissues
to the actions of this secreted
insulin
Curran et al. (2020)
β-cell mass
and
β-cell function
(glucose sensing, insulin secretion and insulin content) appear to be preserved with exercise training in animals and people with T1D
