Effects of dietary carbohydrate on delayed onset muscle soreness and reactive oxygen species after contraction induced muscle damage

Konkluderer med at karbohydrater ikke har noe bidrag til å redusere støhet etter trening. Nevner ROS og forskjellige andre forklaringsmodeller for stølhet. Nevner også flere målemetoder, bl.a. MDA og glutathione (oksidativt stress), Plasma CK activity (muskelskader).


«Muscle damage was assessed from plasma CK activity, with no discernible differences between the two dietary conditions. This would suggest that alteration of glycogen status before exercise has no effect on muscle damage after exercise.»

«There was also no significant difference in ratings of DOMS between the two dietary conditions, suggesting that CHO status before exercise has no affect on muscle soreness.»

«Two days on a high CHO diet significantly increased resting RER and lactate concentra- tions and decreased NEFA concentrations before exercise, suggesting that the diets were successful in altering pre- exercise CHO status.»

«In conclusion, 30 minutes of downhill running at 60% V ̇O2MAX results in a delayed increase in ROS production and muscle damage. However, despite the vital role of glucose as a metabolic fuel, the two day alteration in CHO status before the exercise had no effect on DOMS, muscle function, or ROS production.»
