Introduction. Increasing energy expenditure through certain exercise is an
important component of effective interventions to enhance initial weight loss
and prevent weight regain. Objective. The purpose of this study was to
determine the effect of a 16-week weight loss exercise programme on
morpho-functional changes in female adults and to examine the programme
effects on two subpopulations with different levels of obesity. Methods.
Fifty-six middle-aged women were divided into 2 groups according to their
body mass index (BMI): 25-29.9 kg/m2 - overweight (OW) and ≥30 kg/m2 - obese
(OB). The exercise protocol included a walking technique based on hip
rotation at horizontal plane at speeds close to the preferred transition
speed (PTS). At the initiation of the study and after 16 weeks of the
programme, anthropometric, morphological and cardiovascular parameters of all
subjects were assessed. The main effects of Group (OW and OB) and Time and
the interaction effect of Group by Time were tested by time repeated measures
General Linear Model (mixed between-within subjects ANOVA). Results. Mean
weight loss during the programme was 10.3 kg and 20.1 kg in OW and OB,
respectively. The average fat mass (FM) loss was 9.4 kg in OW and 16.9 kg in
OB. The Mixed ANOVA revealed a significant Group by Time interaction effects
for waist circumference, body weight, body water, fat free mass, FM, %FM and
BMI (p<0.05). Conclusion. The applied exercise protocol has proved as
beneficial in the treatment of obesity, since it resulted in a significant
weight loss and body composition changes. The reduction in body weight was
achieved mainly on account of the loss of fat mass.
