Abstract: Endurance is the
ability of the body to perform
activities or work for a long time without experiencing fatigue. Based on using
of energy systems, endurance is divided into aerobic and anaerobic. Aerobic
endurance is measured using VO2max value. Aerobic endurance is supported by the
availability of carbohydrates and fats. Intake of carbohydrates as much as
30-60 grams/hour can maintain glucose levels and maintain the level of burning
carbohydrates in the body, so it can improve the endurance about 30-60 minutes.
Carbohydrate content in 300 ml of sweet orange juice is 54,9 grams that can be
used to increase endurance atheletes.
Objective : The purpose of this study was to analyze the effect of orange
juice on VO2max value in football
athletes.

experimental design with post test only with controlled group
design. Subject for these study were
tweenty-one football athletes which are match with inclusion criteria in Gendut
Dony Training Camp (GDTC) Salatiga. The Subject has given 300 ml orange juice
and 300 ml placebo 30 minutes before test. VO2max value was measured by using
Balke running test. All datas were analyzed by Independent Sample T-tes.
Result : Subject characteristic includes age, weight, height, body mass
index (BMI), and total food intake were not showing significant difference
(p<0,05), therefore subject were categorized as homogen. Significant
