TI  - The effects of post-exercise feeding on saliva anti-microbial proteins.
AB  - The purpose was to determine the effects of a carbohydrate (CHO)-protein (PRO) 
      drink, consumed immediately after endurance exercise on saliva anti-microbial 
      proteins known to be important for host defence. Eleven male runners ran for 2 h 
      at 75% VO2max on two occasions, and immediately post-exercise were provided, in 
      randomised order, either a placebo solution (CON), or a CHO-PRO solution 
      containing 1.2 gCHO.kg-1BM and 0.4 gPRO.kg-1BM (CHO-PRO). Both solutions were 
      flavour and volume equivalent (12 ml.kg- 1BM). Saliva flow rate, lysozyme, 
      alpha-amylase, and secretory (S) IgA concentrations were determined from unstimulated 
      saliva samples collected pre-exercise, immediately post-exercise and every 30 min 
      until 180 min post-exercise. CHO-PRO ingestion immediately post-exercise resulted 
      in a lower saliva flow rate compared with CON at 30 and 60 min post exercise. 
      Saliva lysozyme concentration increased immediately post-exercise in both trials 
      compared with pre-exercise (P< 0.05), and CHO-PRO ingestion immediately 
      post-exercise resulted in a higher saliva lysozyme concentration in the first 
      hour of recovery compared with CON (125% greater at 30 min; 94% greater at 60 
      min, P< 0.01). Saliva SIgA concentration decreased below pre-exercise 
      concentrations 90-150 min post-exercise (P< 0.01) with no effect of CHO-PRO. 
      Saliva alpha-amylase activity was unaffected by exercise or CHO-PRO re-feeding. 
      CHO-PRO re-feeding did not alter the secretion rates of any saliva variables 
      during recovery. In conclusion, immediate re-feeding with CHO-PRO evoked a 
      greater saliva lysozyme concentration during the first hour of recovery after 
      prolonged exercise compared with ingestion of placebo, but had minimal impact 
      upon saliva alpha-amylase and SIgA responses.
