Pengaruh pemberian sari umbi bit (beta vulgaris) terhadap kadar hemoglobin dan performa atlet sepak bola
Abstract: Nutritional factors
in athletes were very influential to lead achievement. Giving special food or
drink is also important to improve VO2max. One of the substances that can
optimized the levels of VO2max is the content of nitrates in foodstuffs. The
beetroot is one source of food with high nitrate content.
Objective: This study aimed to analyze the effect of bit extract (beta
vulgaris) on Hb Levels and performance among football athlete
Methods: Design of quasi experimental research with pretest-post test
control group approach, conducted on 18 athletes of UNNES Football Club aged
18-22 years. The treatment of beetroot juice was given for 7 days, consist of
P200 treatment group consumed 200 ml, P300 was given 300 ml, while control consumed
300 ml of syrup with the same color with beet extract. Athlete’s performance
was obtained with VO2max levels. VO2max measurements were taken twice using MFT
(multistage fitness test) on day 1 before intervention and day 7 after
intervention. Confounding variables were energy intake, macronutrient intake,
iron intake, vitamin C intake, and smoking habits. The analysis using by
paired-t-test, kruskal wallis, and one way anova.
Result: Most subjects had intake (energy, carbohydrate, fat, protein,
iron and vitamin C) less categories. Most of the subjects had a good category
VO2 Max and were excellent, as well as not anemic. There was no significant
effect of treatment on VO2 Max and Hb level (p <0.05), but the increase in
VO2 Max was greater in group P 300 than in group P 200 and control. Hb levels
of subjects after intervention decreased, but still relatively normal levels.
Conclusions: There was no significant effect of giving beetroot juice on
VO2 Max and Hb levels, but the increase in VO2 Max in group P 300 was higher
than in P group of 200 and control group.
