Every day hundreds of research articles involving diabetes are published. Many will turn out to be inconsequential, a number will add incrementally to our body of knowledge of diabetes and a very few will catapult our understanding of some aspect of care so far beyond our current grasp that it will deserve the moniker revolutionary.
Most of us don’t have the time or interest to wade through the glut of papers published each day to find those that may relate to our lives. But that doesn’t mean we aren’t interested. So here’s a round-up of some studies on exercise that were published over the last few months.
- A study in the October 2012 issue of the British Journal of Nutrition conducted at Glasgow University found that exercise timing can alter the amount of body fat lost. It turns out that going for a sprint before breakfast revs up your fat burning mechanism more than if you did the same activity after breakfast. In addition, participants who exercised pre-meal also had a more significant reduction in blood lipids. So hitting the treadmill before your shower and breakfast may help you shed pounds a mite faster. But don’t worry if you don’t roll out of bed until the alarm has been shrieking for over 10 minutes; exercise anytime you do it is worthwhile.
- Exercise has many benefits including improving cardiac function, lung capacity, sleep and mood. According to a new study presented on June 25 at ENDO 2012, the Endocrine Society’s 94th Annual Meeting, it may also increase testosterone levels. Reduced testosterone levels are a common finding in men with pre-diabetes and type 2 diabetes (weight and testosterone have an inverse relationship). Testosterone, is familiar to most as the male sex hormone, but it also has another role as an anabolic progenitor, increasing muscle and bone mass.
- The Diabetes Prevention Program a long-term clinical intervention whose primary goal was to compare the benefits of lifestyle and drugs on weight loss as a mechanism to reduce the incidence of type 2 diabetes in those at risk, also captured data on testosterone levels of participants. The study divided participants into three arms: those assigned to diet and exercise lifestyle modification, those receiving metformin, an oral hypoglycemic, and those receiving placebo.
Although their was no difference overall between baseline and 12- month levels of testosterone when the groups were compared as a whole, the men in the diet and exercise group has a 15 percent increase in testosterone levels over their baseline values. The authors enrolled these same men in another lifestyle program which included 150 minutes of exercise per week. At the end of a year, testosterone levels had climbed by almost 50 percent.
So if all you men didn’t have a good reason to start or stay with an exercise program before, perhaps this data will give you a nudge.
After all, getting in your 30 minutes with the sun coming up will set you up for eating a good breakfast and starting the day with a smile.
