Pemberian minuman kombinasi maltodekstrin dan vitamin C terhadap mood negatif dan VO2 maks atlet sepak bola

Background: Stress during the match can influence the change of mood and performance of athletes. Physical exercise can improve the ability of physiologically and psychologically, but lead to fatigue, dehydration and hypoglycemia. Maltodextrin has a lower osmolarity to improve emotional and performance. Vitamin C as a cofactor of neurotransmitters can support the performance of athletes.Objective: This study aimed to determine the effectiveness of a combination drinks of maltodextrin and vitamin C on mood and the correlation with VO2 max of football athletes.Method: This research is a quasi experimental with same subject design. The subjects were 14 University state of Yogyakarta football athlete. Subjects received a drink of 15% maltodextrin and 250 mg of vitamin C in 300 ml given 30 minutes before and 5 minutes after the performance test using yo-yo intermittent test continued by physical exercise. Measurement of mood would be done in 3 times; before cardiorespiratory test, 5 minutes after physical exercise, and 15 minutes after drink.Results: There are significant changes after consuming a combination of maltodextrin and vitamin C on the confusion (p<0.05), while components of anger, fatigue, depression, tension and vigor (p>0.05). There are significant changes after consuming plain water on fatigue and tension (p<0.05), while anger, confusion, depression, and vigor (p>0.05). There are no significant differences in every components of mood between two treatments. There is a correlation between anger and confusion with cardiorespiratory after consuming a combination of maltodextrin and vitamin C.Conclusion: Maltodextrin and vitamin C has the potential effect to improve the mood condition and have a correlation with VO2 Max improvement in football athletes.

Background: 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 athleteMethods: 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.

Leukocyte Counts

Backgrounds: The immune system changing affects the fitness. Exercise induces the immune responses, oxidative stress and tissue damage that alters leukocyte counts. Maltodextrin supplies higher energy reserves, that can improve the immune system profiles. Vitamin C as an antioxidant against tissue damage.Objective: This study aims to assess the effectiveness of a maltodextrin and vitamin C combination drink on leukocyte differential count after exercise.Method: This study was quasi-experimental with the within-subject design. Subjects were 14 collegiate football players of the State University of Yogyakarta and fulfilled the inclusion and exclusion criteria. Subjects were selected with a purposive sampling. Subjects received a combination of 15% maltodextrin and 250 mg of vitamin C beverage, 300 mL. Subjects did wash out for 6 days, then received placebo beverage (300 mL plain water). Subjects drank 30 minutes before and 5 minutes after physical exercise. Exercise loads were yoyo intermittent test and run gradually until 80 HRmaks. Blood samples were taken immediately and 30 minutes after exercise.Results: In the administration of intervention beverage, immediately to 30 minutes after exercise neutrophils increased (p=0,006); lymphocytes decreased (p=0.015); monocytes decreased (p=0.000); and eosinophils decreased (p=0.613). In the administration of placebo beverage, immediately to 30 minutes after exercise, neutrophils increased (p=0.359); lymphocytes decreased (p=0.257); monocytes decreased (p=0.146); and eosinophils increased (p=0.549). Neutrophils (p=0.003) and monocyte (p=0.003) had significant difference between both administration drink at 30 minutes after exercise. Lymphocyte and monocyte significantly decrease (p<0.05) at intervention than placebo.Conclusion: Maltodextrin and vitamin C combination drink effect on the decreasing of lymphocyte and monocyte 30 minutes after exercise.

Background: VO2max is one of win determiner in a game. Athletes receive training to improve technical skills, tactical skills, and physiology functions that can support the improvement of VO2max, so they can improve their achievement. Maltodextrin and vitamin C can be used as an ingredient for beverage products which can improve VO2max.Objective: To assess the effect of maltodextrin and vitamin C combination drink on VO2max in soccer athletes.Method: Type of this study was experimental design with the same subject design. The study was conducted from January 2014 until June 2014 at Culinary Laboratory Universitas Gadjah Mada (UGM) and Stadium of Universitas Negeri Yogyakarta (UNY). Subjects of this study were 14 soccer players coming from Universitas Negeri Yogyakarta (UNY). Every subject had to fulfill the inclusion and exclusion criteria, and the subjects were chosen by purposive sampling. In the first treatment, subjects received the combination drink―a drink with a composition 15% of maltodextrin and 250 mg of vitamin C in 300 mL. After 6 days washout period, subjects received 300 mL plain water. Drinks were given 30 minutes before VO2max test. VO2max test method used in this study was yo-yo intermittent recovery test level 2 (IR-2).Results: VO2max when subjects consumed maltodextrin and vitamin C combination drink was significantly lower than VO2max when athletes consumed plain water (p=0,0000).Conclusion: Maltodextrin and vitamin C combination drink was less effective than plain water to enhance VO2max.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.
