Abstract:
The purpose of this study was to investigate the effect of 8-week turmeric supplement combined
with aerobic exercise on VO2max and lactate threshold of third year sport science students of
Debre Birhan University. Thirty-two (32) under graduate third year sport science students free
from any health problems, with age group between 20 – 25 years were selected by random
sampling technique from the total population of 59. Hence, only 32 subjects were complete the
study and purposive sampling was used to select sex and department of subjects in relation with
the study site. The selected subjects were divided into 2 groups i.e. control (16) and experimental
(16) groups randomly each group consisting 16 students (8 males and 8 females). The
experimental group of the subjects underwent 8 weeks’ turmeric supplement within aerobic
excises, three days per week and the duration was 45-minutes while, the control group continued
with only aerobics excises for 8 weeks, three days per week for 45-miuntes. Pre-test, and post
tests were conducted on both variables such as12 minutes cooper test and 30-minutes time trial
test each subject was tested at the same time of day. The data collected from subjects were
analyzed by SPSS version 20.0 and the comparison of mean value results was carried out by
paired sample t-test. The level of significance was p<0.05. The finding of the present study
showed 12 miunte cooper test from pre to post test was showed significant change for
experimental group (Mean Difference 6.75) for male and (MD5.37) for female in experimental
group and little change for control group (MD ,0.5) for male and (MD,0.5) for female in control
group, also 30 miunte time trial test pre to post test showed significant change (MD, 6.76) for
male and (MD,4.93) for female in experimental group and little change showed (MD,0.43) for
male and (MD ,0.43) for female in control group. So this study concluded that 8-weeks turmeric
consumption in combined aerobic exercise have a positive effect on improving of vo2max and
lactate threshold of sport science students of DBU. Based on the above test result alterative
hypothesis was accepted while, null hypothesis was rejected.
