Research of the Day – Nov 14, 2012 – Exercise… It’s good for you… Surprise!

Hey Folks!
I’ve skimmed about a dozen articles today and can’t really find a topic or good quality article I feel like reading, so I chose an easy and semi-boring one, in my opinion. Either way, here it is:

Todays Article:

Resistance Training and Older Adults with Type 2 Diabetes Mellitus: Strength of the Evidence

What did they do:

  • Searched far and wide for articles regarding resistance training and type 2 diabetes outcomes, musculoskeletal outcomes and body composition outcomes between the years of 2000 and 2011.
  • Combined the results from all those studies into a meta-analysis to glean more accurate results than any one study on its’ own

What did they find:

  • 3 studies met the criteria! Not very many and not enough to create statistical significance that wasn’t already found in the original studies, but if you’re the author, you’ve already worked hard to find the info, so you combine it and analyze it anyway… Then it gives people like me an “ok” article to link to and say resistance exercise is good.
  • Resistance training was associated with better muscle strength, functionality and size
  • Resistance training had a favourable but non-significant (meaning it could have been chance) effect on HbA1C (a measure of how high and low your blood sugar gets over a period of time)
  • Moderate and small effects were also favourable for blood pressure and LDL cholesterol, respectively
  • Body composition was unchanged

What it means:

  • Exercise is good for you – could potentially reduce the signs and symptoms of type 2 diabetes (and metabolic syndrome – associated with cardiovascular disease)
  • People got stronger before their body composition changed AKA You are going to get stronger FIRST, and THEN you’ll lose weight and look “cut”, “toned” or whatever other silly adjective you’d like to use for functionally designed
  • Blood pressure, cholesterol, and many other markers that are regularly measured to gauge health will improve when you exercise, but it takes time.

Not overly life changing findings, I know. But a nice reminder to keep up with the great efforts on the gym – If it’s important, do it every day.

Stay healthy, Friends!
