Weight Resistance Training & Weight
Maintenance
Weight Loss Study Aim
To investigate whether walking or resistance training improves weight
maintenance after weight loss when added to dietary counselling.
Weight Loss Study Method
Two months' weight reduction with very-low-energy-diet (VLED) followed
by randomization into three groups (control, walking, resistance training)
for 6 months' weight maintenance (WM) program and 23 months' unsupervised
follow-up. During VLED and WM all groups received similar dietary counselling.
Weight Loss Study Subjects
Ninety healthy, obese, 35-50 year old men started the study and 68 were
measured at the end of the study.
Weight Loss Study Measurements
Weight and body composition assessed by underwater weighing. Exercise
diaries and dietary records to assess energy balance.
Weight Loss Study Results
During VLED the mean body weight decreased from 106 kg to 91.7 kg. Weight
was regained mostly during follow-up and in the end of the study the mean
weight in groups was 99.9-102.0 kg. Exercise training did not improve
short or long-term weight maintenance when compared to the control group.
However, resistance training attenuated the regain of body fat mass during
WM, but not during follow-up. In the combined groups the estimated total
energy expenditure (EE) of reported physical activity was associated with
less weight regain during WM. EE of 10.1 MJ/week was associated with maintaining
weight after weight loss. EE of physical activity tended to decrease after
WM in exercise groups due to poor long-term adherence to prescribed exercise.
Energy intake seemed to increase during follow-up.
Weight Loss Study Conclusion
Exercise training of moderate dose did not seem to improve long-term weight
maintenance because of poor adherence to prescribed exercise.
