Abstract
The
cardiovascular fitness of an individual is determined by his/her VO2max.
VO2max can be measured by direct or indirect
method. Direct method consumes more time and money, whereas indirect
method includes various field tests i.e., Rockport 1 mile walk test,
Cooper test, Shuttle run test, step test etc. Rockport 1 mile walk test
is very convenient as it does not require much equipment and can be
done very easily by the person of any age group. The purpose of the
present study was to compare the VO2 max between
tobacco chewer and non-chewer. VO2 max was measured by Rockport 1 mile
walk test. A total of 50 male volunteer aged between 18-30 years were
randomly selected, their mean age (year), weight (lbs) and height (cm)
were 21.68 (±3.63), 138.43 (±27.52) and 164.44
(±23.17) respectively. Total subjects were divided into two
groups of 25 subjects each. Group A represented by tobacco chewer and
group B represented by non-tobacco chewer. Mean age of tobacco chewer
and non-tobacco chewer were 23.24 (±2.39) and 20.96
(±1.51) respectively. Statistical significant negative
correlation were found between VO2 max with age
(P=-0.587), and body weight (P=-0.279), which suggest as per the age
and weight increases the VO2 max declines.
Statistical significant difference was found in VO2
max (t=-7.38) between tobacco chewer and non-tobacco chewer. Therefore
the result of the present study concluded that tobacco chewing has
negative effect on VO2 max, it can decrease an
individual’s cardiovascular fitness by decreasing VO2
max.
