Effects of 120 vs. 60 and 90 g/h Carbohydrate Intake during a Trail Marathon on Neuromuscular Function and High Intensity Run Capacity Recovery The current recommendations for carbohydrate recording for ultra-trail activities with a duration of more than 2.5 hours amount to 90 g / h. Recently, however, the advantages of taking 120 g / h during a mountain marathon in terms of muscle damage after training were detected. The aim of this study was therefore to analyze the impact of the carbohydrate reception of 120 g / h and to compare with the recommendations (90 g / h) and the usual recording for ultra-endurance athletes (60 g / h) during a mountain marathon. 26 Elite TrailRunners have randomly divided into three groups: Low (60 g / h), med (90 g / h) and high (120 g / h), depending on carbohydrate recording during a run. The runners were measured with the abalakov jump test, a maximum-half squat test and an aerobic power capacity test at the beginning (t1) and 24 hours after completion of the race (T2).Changes in Abalakov jump time The abalakov jump height, the HST1RM between T1 and T2 showed significant differences only in low and med, but not in the high-group.The internal load was significantly lower in the high group in terms of low and med.A significantly lower change during the study in terms of abalakov jump time, the abalakov jump height, the maximum-1 repeat maximum of the square test and in terms of fatigue and lactate within the aerobic service capacity test was in high compared to lowand med.
A carbohydrate reception of 120 g / h during a mountain marathon can limit the neuromuscular fatigue and improve the recovery of high intensity running capacity 24 hours after a physiologically challenging event compared to 90 g / h and 60 g / h.
