Assessment of the effect of Brisk Walking on Anthropometric and Body Composition Indices of Obese Female Adults.
ABSTRACT
This study was conducted to assess the effect of brisk walking on anthropometric and body composition indices of obese female adults in Kaduna metropolis, Nigeria.
To achieve this purpose repeated measure research design was used for this study. The population for the research was obese female adults of Kaduna metropolis.
Using purposive sampling, 17 obese female adults with body mass index between 30.0 and 39.9 kg/m2 and ages of 40 – 50 years who met the inclusion and exclusion criteria were selected for this study. There were 3 attritions leaving 14 participants in the group.
The training group was subjected to, brisk walking for 30-50 minutes with 10 and 5 minutes of warm up and cool down activities respectively. The exercise programme was conducted on 3 alternate days per week for 12 weeks.
Body weight, height, waist and hip circumferences, visceral adipose fat, percent body fat and lean muscle mass were measured at base-line, immediately after the 6th and 12th week of training period.
The descriptive statistics of mean, standard deviation and standard error of means were used to analyze the data of the physical characteristics of the participants.
Repeated-measures ANOVA was used to assess the effect of training on all the assessed variables while post hoc Bonferroni Multiple comparison was used to evaluate the effect of the training on the variables.

INTRODUCTION
1.1 Background of the Study
Life-style is generally considered a personal issue. However, World Health Organization (WHO) (2016b), reported a strong correlation between mortality rate and lifestyle practices globally.
One of such lifestyle practices is physical inactivity or sedentary living which was highlighted as one of the causes of obesity, leading to metabolic and cardiovascular diseases and other related problems (Ding, Rogers, Van der Ploeg, Stamatakis &, Bauman, 2015; WHO, 2016b).
Experts in nutrition stressed that obesity is difficult to define qualitatively; but it is generally accepted that anyone who has a body mass index (BMI) equal to or greater than 30kg/m2 is obese (Kent, 2005; WHO, 2016b).
It generally results from a chronic imbalance between energy intake and expenditure resulting in weight gain mostly as fat (Ahima, 2010).
Globally, there has been an increased intake of energy-dense foods that are high in fat; and an increase in physical inactivity due to the increasing sedentary nature of many forms of work, changing modes of transportation and increasing urbanization (WHO, 2016b).
Changes in dietary and physical activity patterns are often the result of environmental and societal changes associated with development and lack of supportive policies in sectors such as health, agriculture, transport, urban planning, environmental, food processing, distribution and marketing as well as education (WHO, 2016b).
