Influence of acute vitamin C and/or carbohydrate ingestion on hormonal, cytokine, and immune responses to prolonged exercise

Article Abstract:

A study was conducted to examine the effects of vitamin C (VC) with or without carbohydrate (CHO) consumed acutely in beverages before and during prolonged exercise on immunoendocrine responses. The findings suggest that acute supplementation with a high dose of VC has little or no effect on the hormonal, interleukin-6, or immune response to prolonged exercise and combined ingestion of VC with CHO provides no additional effects compared with CHO alone.

Recovery from run training: Efficacy of a carbohydrate-protein beverage?

Article Abstract:

Prolonged and strenuous training performed over consecutive days without any sufficient dietary carbohydrates can deplete muscle glycogen and effect performance. Optimal nutrition is important in order to recover from training, carbohydrate protein drinks consumed within 30 minutes after running improve performance.

Preexercise carbohydrate consumption and repeated anaerobic performance in pre- and early-pubertal boys

Article Abstract:

The effect of preexercise carbohydrate (CHO) feeding on performance on a Wingate anaerobic test (WAnT) is examined in 11 boys. It is found that the ingestion of a CHO solution before exercise did not influence power output during repeated performances of the WAnT.
