| Abstract | ||
| Background: Regular intensive gymnastic exercise activities causes muscle glycogen and protein depletion. Post-exercise recovery helps re-synthesis of glycogen and proteins. Ingestion of carbohydrates alone or with protein after exercise stimulates re-synthesis. All previous studies investigated tissue biopsies for estimating glycogen and protein resynthesis. The initiation of glycogen synthesis is provided by a self-glucosylation of a protein self extracting enzyme glycogenin under the control of insulin and blood glucose levels. Plasma glycogenin could be used as a good marker for glycogen resynthesis. Methods: Sixteen male students from the faculty of physical education for boys, Menufia University, grade four were constituted subjects of this study. They were subgrouped in two equal groups, subjected to a gymnastic training program for three months. The first group (control) ingested sucrose at the end of every training session while the second (experimental) ingested a mixture of CHO/protein beverage. Their anthropometric measurements and blood glycogenin-1, insulin and glucose were assayed and correlated. Results: All variables were revealed significant improvement in all physical measurements with increased response of post exercise blood levels in glycogenin-1 and insulin with administration of post-exercise sucrose or CHO/protein drinks with most higher results of the mixture. Conclusions: It is concluded that gymnastic training program with post exercise carbohydrate or CHO/protein intake increase the physical efficiency with improved high performance. | ||
