Effect of caffeinated drink on endurance performance of the athlete

Abstract

The main purpose of the study was to find the effect of caffeinated drink on endurance performance of the athlete. For the data collection researcher selected the subjects of Bharati Vidyapeeth College of physical education. The researcher considered following procedures for the research on a sample of 14 athletes with the age of 18 to 25 years. The selection of sample is purely on the random sampling method. The researcher experimented on the collegiate level athletes of B.V.D.U C.O.P.E, and explained the test to the group. Only one group was examined. After the researcher took the pretest of the group, one day full recovery period was given to the group. Next day the subjects were given caffeinated drink (instant coffee) 3-5mg per kg body weight and after 30 minutes of the drink taken, the group was taken for the test. The test taken was 12 minute run/walk test for the cardiovascular endurance. Once the stretching and warm up was done the group undergone posttest and hence data was collected. The result was formulated using independent T-test. The result revealed that statistically there was no significant difference in the variable (Table't' value > calculated't' value). It was seen that the short term effect of caffeinated drink (instant coffee) does not improve the performance.

Abstract
The main purpose of the study was to find the effect of caffeinated drink on endurance performance of the athlete. For the data
collection researcher selected the subjects of Bharati Vidyapeeth College of physical education. The researcher considered
following procedures for the research on a sample of 14 athletes with the age of 18 to 25 years. The selection of sample is purely
on the random sampling method. The researcher experimented on the collegiate level athletes of B.V.D.U C.O.P.E, and explained
the test to the group. Only one group was examined. After the researcher took the pretest of the group, one day full recovery
period was given to the group. Next day the subjects were given caffeinated drink (instant coffee) 3-5mg per kg body weight and
after 30 minutes of the drink taken, the group was taken for the test. The test taken was 12 minute run/walk test for the
cardiovascular endurance. Once the stretching and warm up was done the group undergone posttest and hence data was collected.
The result was formulated using independent T-test. The result revealed that statistically there was no significant difference in the
variable (Table‘t’ value > calculated‘t’ value). It was seen that the short term effect of caffeinated drink (instant coffee) does not
improve the performance.
Keywords: caffeine, cooper test, cardiovascular endurance etc.
Introduction
Caffeine is a diuretic, meaning that it increases urine
production, which could theoretically exacerbate dehydration
during exercise. However, exercise negates this effect if
caffeine. In a recent scientific review, researchers from the
University of Connecticut wrote, “Dieticians, exercise
physiologists, athletic trainers, and other sports medicine
personnel commonly recommend that exercising adults and
athletes refrain from caffeine use because it is a diuretic, and it
may exacerbate dehydration and hyperthermia. This review,
contrary to popular beliefs, proposes that caffeine
consumption does not result in the following: (a) water-
electrolyte imbalances or hyperthermia and (b) reduced
exercise-heat tolerance. Caffeine is commonly used by
endurance athletes 30 to 60 minutes before races to enhance
competitive performance. The ergogenic effect of caffeine is
dose-dependent. The maximum effect is seen with doses of 5
to 6 milligrams per kilogram of body weight. For a 150-lb
runner this translates to roughly 340-400 mg, or the amount of
caffeine you’d get in 14 to 17 ounces of drip brewed
coffee. The minimum amount of caffeine the average runner
must consume for a measurable ergogenic effect is about 2 mg
per kilogram of body weight. It makes less sense to use
caffeine as a daily workout performance enhancer, for two
reasons. First, workouts are seldom maximal efforts. Second,
the ergogenic effects of caffeine consumption decrease with
habituation. For this reason, if you are a regular coffee drinker,
you should cease coffee consumption four to six days before
participating in a race.
Methodology
14 athletes from age group of 18 to 25 years were selected
from Bharati Vidyapeeth College of physical education. The
test conducted was 12 minutes run/walk test where students
have to continuously run/walk till 12 minutes. The distances
covered by the students were measured in meters. The score in
meters is determined by multiplying the number of complete
lap’s times the distance of each lap (450 meters), plus the
number of segments. For the data analysis independent ‘t’test
was used as statistical tool. The level of significance was 0.05.
Method of measurement of variable
For the purpose of establishment reliability of the data the
tests held coopers 12 minutes run/walk test. One day recovery
was given to the subjects between pre and posttest.

Discussions and Conclusions
Many researchers claimed that intake of caffeine before the
competition does not increase the performance.
Following conclusions were drawn after the analysis of the
data-:
 There is no significant difference in pre and post-test of the
group. Hence caffeinated Drink did not show any effect
after intake.
 Intake of caffeinated drink does not affect the
cardiovascular endurance of athletes after intake.
