Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
From March 2010 to August 2011 a total of 60 sedentary young women without contraindication for exercising were included. Study was carried out at Department of Endocrinology, Cardiology and Internal Medicine of the INCMNSZ.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In the initial visit, patients were instructed to keep unaltered their diet, lifestyle and physical activity. Basal daily physical activity was evaluated with a questionnaire. All participants were assigned to the intervention group. All subjects underwent basal and final physical and biochemical evaluation.

Reporting Groups
  Description
Supervised Exercising A treadmill exercise test (following the Bruce’s protocol) was done five times per week (from Monday to Friday) for two weeks to participants.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
We cannot fully control other potential sources of physical activity. The results may not be applicable to men. We did not register the caloric consumption during the study.
