Abstract
The
objective of the present study was to determine the effect of
pre-exercise consumption of sports drink in enhancing
cardio-respiratory fitness. A total of 50 male individuals participated
in the present study with the mean age of 21.97 years (SD=
±1.42) and their mean weight (in lbs) were 138.86 (SD=
±19.48). All 50 subjects were placed in three groups as same
subject design. In group A they all performed Rockport 1 mile walk test
without taking any supplement and then their VO2max was measured. In
group B the VO2max of all subjects were measured after one week of
first session by Rockport 1 mile walk test after consuming sports drink
(Gatorade) 20 minutes prior to the test. In group C again the VO2max
was measured after one week of second session by Rockport 1 mile walk
test after consuming placebo drink (coloured glucose solution) 20
minutes prior to the test. Statistically significant differences were
found in VO2max between group A (F=61.53), group B (F=20.96) and group
C (F=66.22). The finding of the present study reveals that pre-exercise
ingestion of carbohydrate supplement is helpful in increasing VO2max
during exercise. The effect of sports drink and simple glucose is
relatively similar.
