Abstract The glycogen content in muscle tissue of the quadriceps femoris and the deltoid muscles was examined in four healthy subjects, performing a ski race of 85 km. Muscle samples were obtained before, after 45 km, and at the end of the race. The glycogen content before was above the normal range in all the subjects due to a special training and diet program. The decrease of glycogen in the leg muscles was most pronounced during the first part of the race and also at the end there was a sufficient amount of glycogen in the leg muscles. In the arm muscles, on the other hand, practically complete exhaustion of the glycogen store was found at the end of the race. The subjects experienced a marked feeling of tiredness in the arm muscles during the last kilometers of the race. The result can partly be explained by the topographical profile of the race.
