The medical history of each volunteer was analyzed
and the researcher instructed them about the appropriate
procedures to be followed in the study such as the types
of exercise would be done, intensity of the heart rate
(HR) and how blood pressure would be measured and
monitored, and other questions that emerged eventually.
In addition, the values of weight, height, waist, and hip
circumferences were recorded and Body Mass Index
(BMI) was calculated. Thereafter, the volunteers remained
seated in a quiet and comfortable place for 30 minutes
in order to measure the heart rate and blood pressure
at rest.. All participants had a recent medical certificate
that attested they had appropriate conditions for the practice
of physical activities.
