How do Aerobic and Anaerobic
Exercise Compare in the Ability
to Alter Cardiac Risk in
Overweight Adults?
Recently researchers from Brazil examined the effects of 12
weeks of aerobic or anaerobic exercise on cardiac risk factors
with 22 over weight adults with a mean age of 40±8.
The exercise sessions for both groups were performed 3
days per week and duration of activity was progressively
increased from 20 minutes in the first week to 60 minutes
in the fifth week where it stayed for the remainder of the
12 week study. In the aerobic group continuous activity
was performed at 10 % under the lactate threshold, while
the anaerobic group performed intervals at 20% above
the lactate threshold at a work-to-rest ratio of 2:1.
Prior to
the initiation of the study, and immediately after, the following
measures were performed: total body mass, body
mass index, waist circumference, hip circumference, and
body composition. Additionally, plasma concentrations of
glucose, total cholesterol, and triglycerides were assessed.
the initiation of the study, and immediately after, the following
measures were performed: total body mass, body

body composition. Additionally, plasma concentrations of
glucose, total cholesterol, and triglycerides were assessed.
Both exercise interventions resulted in significant reductions
in total body mass, waist circumference, body mass
index, and plasma glucose levels. Only the aerobic group
demonstrated reductions in total cholesterol and hip circumference.
Conversely, only the anaerobic group demonstrated
significant reductions in the waist to hip ratio.
Based upon these results it appears that both aerobic and
anaerobic exercise interventions have the potential to favorably
alter cardiovascular risk factors. However, the authors
of this investigation suggest that both aerobic and
anaerobic exercise interventions are warranted to maximize
the effectiveness of the exercise regime.

thanks for interesting article. i need your help. my 16 years old daughter is planning to become a preffesionel dancer.the only problem is that she has rather short legs and an extra kilo or two on her hips. any suggestions? any special diet or specific exercises she should be doing?
Hey Anti,
Well, there is nothing wrong about the height of your daughter. I know dancers that are short in height, but have other charismas.
As for the nutrition and diet tips...it all depends on the degree of specificity. There are a lot of things that she can improved upon.
A well-detailed assessment will reveal any imbalances in training and on the other hand visiting a nutritionist will help her maintain a healthy diet.
If you live in Cyprus and you want some information on the subjects, I'm happy to provide them.
Because she is young, the best thing to do is to maintain a healthy diet and exercise 3 times a week(activities that she enjoys). She must realize that if she wants to loose weight she needs to eat proberly, yet she should not have the wrong mentality that with no food she will achieve her goals.
