Brief Summary

The study is a randomized, double-blinded, placebo-controlled trial that will include the participation of 14 Jiu-Jitsu athletes between 18 and 33 years. The aim of the study is to evaluate the effects of carbohydrate consumption on fatigue and exercise-induced muscle damage in Jiu-Jitsu athletes.

Conditions

Fatigue; Exercise-induced Muscle Damage

Outcome Measures

Primary Outcomes (1)

• change in upper limbs strength

  Kimono Grip Strength Test

  Pre-exercise; at 2 intervals during exercise; 24hour and 48hour after exercise

Secondary Outcomes (6)

• change in lower limbs power

  Pre-exercise; at 2 intervals during exercise; 24hour and 48hour after exercise

• change in hand grip strength

  Pre-exercise; at 2 intervals during exercise; 24hour and 48hour after exercise

• change in creatine kinase

  Pre-exercise; immediatly post-exercise; 24hour and 48hour after exercise

• change in glucose
