CrossFit is a high-intensity training intervention incorporating both endurance and strength training. Sessions range from 8-20 minutes in duration and represent a far more time-effective form of exercise than traditional exercise interventions.
CrossFit has been growing in popularity over the past decade, although until now it was not clear whether such forms of exercise would improve the ability of individuals with Type II diabetes to control their sugar levels.
For this research, thirteen overweight/obese patients with Type II diabetes were recruited to participate in a 6-week CrossFit exercise programme. Participants’ blood sugar levels and insulin sensitivity (an individual’s ability to reduce high blood sugar levels effectively) were assessed both before and after the exercise programme, in addition to their blood chemistries and blood pressure, which were tested to predict heart disease risk.
