Effects of Soluble Dietary Fiber on Sport Efficiency and Fatigue Delay in Top Basketball Players

Summary

Athlete nutrition is becoming an increasingly important factor on the path to achieving top results. Nutrients such as soluble fiber can alter the intestinal microbiota, resulting in metabolites with a positive effect on metabolism. Thus, the fibers become available, an additional source of energy to the host, have an anti-stress effect and delay the feeling of fatigue. The primary goal of the study is to determine the impact of soluble dietary fiber on increasing athletic efficiency, the secondary goal is to determine the impact of fiber on delaying fatigue. Subjects will be randomly divided into experimental and control group. The sample of variables will consist of genome microbiota genome sequencing data, measures to assess morphological characteristics, lower extremity explosive strength tests, and cardiovascular endurance. The statistical package SPSS will be used for data processing. The expected scientific contribution of this research is to expand the scientific knowledge about the importance of dietary fiber in the diet of athletes with the aim of improving sports performance.

Interventions

DIETARY_SUPPLEMENT

Soluble dietary fiber with prebiotic properties

14 adult professional baskeyball players will be divided randomly in two groups, each containing 7 players. One group shall receive Nutriose fiber, two times per day 10 grams per dose in total duration of 4 weeks. Second group shall receive same amount of Placebo in form of Maltodextrin. Each group will undergo a series of sports performance tests and questionnaires and shall donate their feces several times during the study in order to monitor gut microbiota changes. The Nutriose group in this particular intervention contains 7 randomy selected players.

DIETARY_SUPPLEMENT

Placebo

14 adult professional baskeyball players will be divided randomly in two groups, each containing 7 players. One group shall receive Nutriose fiber, two times per day 10 grams per dose in total duration of 4 weeks. Second group shall receive same amount of Placebo in form of Maltodextrin. Each group will undergo a series of sports performance tests and questionnaires and shall donate their feces several times during the study in order to monitor gut microbiota changes. This second (Placebo) group also consists of the 7 players and receives Maltodextrin supplementation. Since the study type is "double-blind", neither the participants (players) nor the person handing out the supplementation know the exact nature of fiber substance being handed during the entire duration of the trial. Independent statistician is handling the randomization of both interventions.
