Post-exercise Carbohydrates Increase The Magnitude Of The Inflammatory Response
Chris M. Depner, Sara J. Frederickson, Kitrick Rhodes, Kelly Bond, Rita Barry, Rochelle Kirwan, Mary P. Miles, FACSM. Montana State University,

PRUPOSE: To determine the influence of high carbohydrate intake during recovery from eccentric exercise on the inflammatory response.
METHODS: The study was a cross-over design. College aged men and women (n=12) completed high carbohydrate and high fat/protein conditions in counterbalanced order.
Both conditions consisted of 6 sets of 10 maximal high-force eccentric contractions of the elbow flexors and extensors. The exercise was followed by a controlled diet for the
first 8 hours post-exercise based on the condition. Interleukin-6 (IL-6), interleukin-1b (IL-b), and C-reactive protein (CRP) were measured as indicators of inflammation preexercise,
1.5, 4, 8, and 24 h post-exercise. Blood glucose and insulin were measured at these same time points to identify differences between diets in the conditions. Creatinekinase
(CK), muscle soreness, and isometric strength loss were measured as indicators of muscle damage through 120 h post-exercise.
RESULTS: Insulin increased (p<0.01) in the high carbohydrate condition compared to the high fat/protein condition at 1.5, 4, and 8 hours post-exercise. Perceived soreness was elevated
(p<0.001) at all time points post-exercise in both conditions and was higher (p<0.05) in the high carbohydrate condition compared to the high fat/protein condition. There was a main
effect trend (p = 0.064) for IL-6 to be greater in the high carbohydrate condition compared to the high fat/protein condition. Il-1b increased (p = 0.05) 24 hours post-exercise in the high
carbohydrate condition compared to the high fat/protein condition.
CONCLUSION: The inflammatory response following eccentric exercise was higher in the high carbohydrate compared to the high protein/fat condition, as evidenced by
augmented IL-1b and IL-6 (trend only) responses. This is consistent with greater perceived muscle soreness post-exercise in the high carbohydrate condition. Additional
research is required to investigate whether this response to high carbohydrate intake has the potential to influence recovery from strenuous exercise or the development of
chronic diseases related to inflammation.

Dans son master l'auteur dit qu'il provoque une hyperglycémie en post-training car l'hyperglycémie peut augmenté l'inflamation qui a été initiée par une autre source.
Pour provoquer l'hyperglycémie, ils ont utilisé des "cliff bar", du jus d'orange, du lait à 2% et des corn flakes.

donc cela augmente la réponse inflamatoire, d'un point de vue santé générale, ce n'est pas une bonne chose bien sur, mais pour le muscle, il me semblait que cela n'était pas si mal ?
