Study type | Interventional |
This project aims to evaluate if after 14 days of grape juice ingestion there is improvement of the parameters of strength, fatigue and oxidative stress in judo fighters. The study will be a randomized, blind, crossover clinical trial of 20 Judo athletes. Judo wrestling simulations will be performed on 3 different days.

Other | Lactate in numbers | Specific to muscle fatigue, a state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle. | 15 days | |
Other | Upper and lower limb strength in repetitions or numbers in meters | Specific to muscle fatigue, a state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle. | 15 days | |
Other | Palmar grip strength - in strength and time | Specific to muscle fatigue, a state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle. | 15 days | |
Other | muscle pain | Specific to muscle fatigue, a state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle. | 15 days | |
Primary | Oxidative stress In Blood Collection | A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. | 15 days | |
Secondary | Borg in scale. | Specific to muscle fatigue, a state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion.
