Abstract:
We investigated whether preference for sucrose solution changes after exercise and whether the change influences post-exercise recovery of body fluid and glycogen. Rats were individually housed in cages equipped with 2 bottles containing water and either a 0.4%, 2%, 4 % or 8 % sucrose solution. The rats had free access to the water and sucrose solution for 6 h on both the day before (Pre) and the day of 2 h treadmill exercise (Ex). Fluid intake was measured. We also measured tissue weight, tissue water and tissue glycogen after 6 h recovery. Compared to Pre, voluntary fluid intake on Ex significantly decreased for 2 % and 4 % solutions, whereas it did not change for 0.4% and 8 %. After 6h of fluid ingestion, the content of tissue water and glycogen was highest for 8 % among the solutions. These results demonstrate that 8 % was effective in rehydration and tissue glycogen recovery after exercise, since its voluntary intake did not decrease after exercise.
