Abstract
This study examined the effects of 12 -week moderate intensity interval training in running on
body fat patterns, lipids and lipoproteins, blood glucose and cardiovascular efficiency variables
of sedentary Nigerian male adults. The body fat pattern variables included weight, waist
circumference, hip circumference, Body Mass Index, Waist- Hip-Ratio and Conicity Index.
lipids and lipoproteins included Total Cholesterol, Triglycerides, High Density Lipoprotein
Cholesterol and Low Density Lipoprotein Cholesterol, fasting blood glucose. The variables
covered under cardiovascular efficiency included systolic and diastolic Blood Pressure, Mean
Arterial Pressure, Resting Pulse Rate and Double Product. A 2 x 3 factorial design was used for
this study in which 30 medically certified healthy sedentary adult men aged, between 20-30
were selected after obtaining their informed consent and were randomly divided into
experimental and control groups of 15 subjects each.. The experimental group went through the
training using running as an exercise mode performed at 55-68% of maximum heart rate. The
training was done 4 times a week for 12 weeks. During the intervention period, three tests were
conducted on both groups at baseline, midway and immediately after the termination of training
at week 12.The data obtained was analysed using the Statistical Package of the Social Sciences
(SPSS) of the Iya Abubakar Computer Center of the Ahmadu Bello University Zaria Nigeria.
The descriptive statistic of the mean and standard deviation were used for data description while
the independent t-test was employed to determine the difference between the experimental and
control groups. The comparison of the difference between changes in test periods week zero
,sixth and twelfth were made using the repeated measure ANOVA. The result of this study
indicated significant decreases in waist circumference and cardiovascular efficiency variables.
However, 12 week moderate intensity interval training in running performed 4 times weekly was
not found to be adequate to produce significant changes in weight‚ hip circumference, Body
Mass Index, Waist-Hip-Ratio, Conicity Index.,Serum glucose, lipids and lipoproteins of
sedentary Nigerian male adults. The not significant changes observed in the other variables may
be attributed to the short duration of the intervention or the exercise intensity used in this
investigation. The changes observed in these variables however, were minimal and were visible
especially in week 12. In the light of these findings, it is recommended that moderate intensity
interval training in running can be used to improve cardiovascular efficiency or fitness and
reduction in waist circumference of sedentary Nigerian male adults. Following the changes
observed towards the end of the training, it is also recommended that longer duration and a
higher intensity interval training may be used to bring about the desired changes in variables
such as hip circumference, BMI, WHR, CI, blood glucose, lipids and lipoproteins of sedentary
Nigerian male adults
