The latest research on diabetes and exercise.

Exercise and rising blood sugar - what you need to know

The Diabetes Health magazine recently published an explanatory article on why blood sugar can rise during or as a result of exercise.

Effects of reducing pre-exercise insulin on the production of ketones during and after exercise

Are you at risk of generating ketones if you reduce your insulin before exercising?  Researchers have uncovered some comforting answers on this topic.

Fear of Hypo's - the biggest barrier to physical exercise

A Canadian study on adults living with type one diabetes (November 2008) confirms what many of us know already: the biggest barrier to regular exercise is fear of hypoglycaemia.

Previous studies have found that for over 60% of people living with type one diabetes, exercise is not a part of their lifestyle.

Exercise can prevent Peripheral Neuropathy

This Italian study looked at the long term benefits of aerobic exercise on the prevention of the onset of peripheral neuropathy.

It concluded,

This study suggests, for the first time, that long-term aerobic exercise training can prevent the onset or modify the natural history of DPN.

Challenges of Vigorous Exercise

Michael Riddell and Bruce Perkins are Canadian leaders in diabetes and exercise medical research and advice.

In this article, they discuss the risks, challenges and strategies to enable effective participation in vigorous exercise activities, such as team sports.  They also discuss the impact of pressure associated with competition.

Adolescents and the Value of Exercise

Researchers in the US tracked the changes in a group of adolescents over a 12 week period, where exercise was introduced but no changes made to their insulin and diet regimes.  The study concluded:

'...exercise training may be a valuable adjunct in managing type I diabetes providing there is concomitant attention to diet and insulin. Exercise training alone, however, does not improve glycemic control, although it improves physical fitness and insulin sensitivity.'

Intensity of Exercise Shows Greater Rewards for Insulin Sensitivity

Researchers in Japan found a benefit from high intensity, intermittent swimming on the sensitivity of muscle glucose uptake to insulin following exercise, when compared to low-intensity prolonged exercise.  This research was conducted on rats:

Sprints

Can a mid-exercise sprint bring you out of or even delay a hypo?
This question was asked recently by researchers who undertook a small study on the adrenaline effect and avoiding hypos both during and after moderate exercise.

Type 1 Diabetes: Recent Developments

"The incidence of type 1 diabetes is increasing rapidly worldwide, and it is also presenting at an earlier age. Genetically engineered human insulins have improved care of type 1 diabetes, and devices for continuous glucose monitoring may revolutionise care. An interplay between genetic susceptibility and environmental factors (triggering or suppressive) may account for the pathogenesis of type 1 diabetes.
