TI  - Carbohydrate feedings during team sport exercise preserve physical and CNS 
      function.
PG  - 306-15
AB  - PURPOSE: This study was designed to examine the effect of carbohydrate (CHO) 
      feedings on physical and central nervous system (CNS) function during 
      intermittent high-intensity exercise with physical demands similar to those of 
      team sports such as basketball. METHODS: Twenty active men (N = 10) and women (N 
      = 10), with experience competing in team sports, performed three practice 
      sessions before two experimental trials during which they were fed either a 6% 
      CHO solution or a flavored placebo (PBO). Experimental trials consisted of four 
      15-min quarters of shuttle running with variable intensities ranging from walking 
      (30% VO(2max)), to running (120% VO(2max)), to maximal sprinting, and 40 jumps at 
      a target hanging at 80% of their maximum vertical jump height. Subjects received 
      5 mL.kg(-1) of fluid before exercise and 3 mL.kg(-1) after exercise, in addition 
      to 3 mL.kg(-1) over a 5-min span after the first and third quarters, and 8 
      mL.kg(-1) during a 20-min halftime. During each break, the subjects performed a 
      battery of tests measuring peripheral and CNS function, including 20-m sprints, a 
      60-s maximal jumping test, internal and external mood evaluation, cognitive 
      function, force sensation, tests of motor skills, and target-jumping accuracy. 
      RESULTS: Compared with PBO, CHO feedings during exercise resulted in faster 20-m 
      sprint times and higher average jump height in the fourth quarter (P < 0.05). CHO 
      feedings also reduced force sensation, enhanced motor skills, and improved mood 
      late in exercise versus PBO (P < 0.05). CONCLUSION: These results suggest that 
      CHO feedings during intermittent high-intensity exercise similar to that of team 
      sports benefited both peripheral and CNS function late in exercise compared with 
      a flavored placebo.
