Effect of two different regimes of carbohydrate and protein on performance and serum level of insulin and glucose in soccer players

摘要

Background: The aim of this study was to determine the effect of two different regimes, containing different carbohydrate to protein ratios on performance, serum glucose and insulin after exercise in soccer players in Tehran; Iran. Methods: Nineteen male soccer players under training [age = 17/5 +/- 1.5 (SE) yr] were selected and completed two sequential trials separated by 1 week, in a paired cross-over study design. In each trial, subjects after running to fatigue; received one of three regimes, using a random- order design as follows: HPRO ( CHO 56%, PRO 19% & fat 25% of total energy); HCHO ( CHO 64%, PRO 11% & fat 25% of total energy) or control ( CHO 60%, PRO 15% & fat 25% of total energy). The calorie of 3 regimes were equal. After consumption of meal up to120 min, blood was obtained before and at intervals. After 3 hours athlete performance was measured. Results: The study indicates no significant difference in the serum insulin and glucose response among three regimes (P > 0.05). There was no difference in performance between three regimes after 3 h (p > 0.05). Conclusion: The results suggest that post exercise regimes have no influence on performance, serum glucose and serum insulin. Thus total energy content and carbohydrate content may be important in recovery after exercise.
