The effects of solid and liquid carbohydrate feedings on high intensity intermittent exercise performance Walton, Peter Trent
Abstract
Ten elite female soccer players were studied to determine the effects of pre-exercise solid carbohydrate (SCHO) and liquid carbohydrate (LCHO) feedings on high intensity intermittent exercise performance. At 5 min pre-exercise subjects consumed either 50 g of SCHO + 400 ml of H₂O , 50g of LCHO in a 400 ml solution, or 400 ml of artificially sweetened H₂O (PL). Exercise consisted of two 19 min periods of high intensity intemittent running separated by a 10 min break. At 5 min post-exercise, subjects completed a performance trial (PT) in which they ran repeated 10 s, 120% V 0 2 max sprints in a 1:1 work to rest ratio until exhaustion. Blood lactate was not different (p>0.05) between feedings. Blood glucose (BG) was greater (p<0.05) for SCHO and LCHO at 10, 20, and 30 min during exercise compared to PL. At 40 min B G was not significantly different between SCHO and PL and SCHO and LCHO. However, at 40 min BG for LCHO was significantly higher than PL. At 2 min post-exercise BG was similar between interventions. Time to exhaustion in PT was greater in both carbohydrate trials compared to PL (X ± SE, SCHO = 693 s ± 135, LCHO = 648 ± 113, PL = 436 ± 70; p<0.01). Results indicate that the intake of equal amounts of SCHO and LCHO 5 minutes prior to high intensity intermittent exercise improve performance similarly.

Ten elite female soccer players were studied to determine the effects of pre-exercise solid
carbohydrate (SCHO) and liquid carbohydrate (LCHO) feedings on high intensity
intermittent exercise performance. At 5 min pre-exercise subjects consumed either 50 g of
SCHO + 400 ml of H₂O , 50g of LCHO in a 400 ml solution, or 400 ml of artificially
sweetened H₂O (PL). Exercise consisted of two 19 min periods of high intensity
intemittent running separated by a 10 min break. At 5 min post-exercise, subjects
completed a performance trial (PT) in which they ran repeated 10 s, 120% V 0 2 max
sprints in a 1:1 work to rest ratio until exhaustion. Blood lactate was not different
(p>0.05) between feedings. Blood glucose (BG) was greater (p<0.05) for SCHO and
LCHO at 10, 20, and 30 min during exercise compared to PL. At 40 min B G was not
significantly different between SCHO and PL and SCHO and LCHO. However, at 40 min
BG for LCHO was significantly higher than PL. At 2 min post-exercise BG was similar
between interventions. Time to exhaustion in PT was greater in both carbohydrate trials
compared to PL (X ± SE, SCHO = 693 s ± 135, LCHO = 648 ± 113, PL = 436 ± 70;
p<0.01). Results indicate that the intake of equal amounts of SCHO and LCHO 5 minutes
prior to high intensity intermittent exercise improve performance similarly.
