TI  - Influence of liquid and solid meals on muscle glycogen resynthesis, plasma fuel 
      hormone response, and maximal physical working capacity.
PG  - 99-104
AB  - The effect of forced liquid (L) or solid (S) carbohydrate (CHO)-rich feedings on 
      plasma glucose, insulin, and glycogenesis after glycogen depletion was 
      investigated. The relationship between glycogen restoration and maximal physical 
      working capacity (MPWC) was studied as well. Eight males performed two 
      experiments, with 2 weeks interval, on a bicycle ergometer. In each experiment, 
      MPWC was determined in a graded test, which was immediately followed by interval 
      work until exhaustion. After exercise cessation (EC), the subjects started to 
      consume a standardized amount of concentrated L or CHO-rich food. Insulin and 
      glucose concentration in blood were determined. Muscle glycogen was determined 
      before, immediately after, 5 h after, and 22 h after EC. MPWC was determined 
      again 22 h after EC. Four subjects performed a third experiment, in which solid 
      food consumption was left ad libitum (AL). A rapid glycogen repletion was found 5 
      h after EC, i.e., from 72 +/- 40 to 198 +/- 38 mmol/kg in the S, and from 69 +/- 
      39 to 192 +/- 40 mmol/kg in the L experiment. The higher plasma glucose and 
      insulin levels (P less than 0.05) during the 5 h after EC in the S experiments 
      did not elicit a difference in glycogen repletion. Glycogen synthesis rate in the 
      AL experiment was lower (P less than 0.05) than in the L and S experiments. 
      Glycogen restoration in the L and S experiments was complete 22 h after 
      depletion. However, despite repletion of glycogen, MPWC was decreased (P less 
      than 0.05) in both experiments.(ABSTRACT TRUNCATED AT 250 WORDS)
