The Effect of Glutamine and Maltodextrin Acute Supplementation on Anaerobic Power |
|
| چکیده انگلیسی مقاله |
Purpose: The aim of this study was to investigate whether supplementation of carbohydrate together with peptide glutamine would prevent anaerobic power decrease during repeated competitions. Methods: Twenty-eight physical education male students voluntarily participated in the study. Subjects were randomly divided on a Maximal power (Max power) output value basis to four groups: 1) G group (Oral ingestion of glutamine at the dose of 0.25 g/kg body mass in 250 ml of water), 2) M group (A single carbohydrate at a concentration of 50g of maltodextrin in 250 ml of water), 3) GM group (Carbohydrate at a concentration of 50g of maltodextrin + Glutamine at the dose of 0.25 g/kg body mass in 250 ml of water) and, 4) P group (Just 250 ml of water and 30 gram sweetener). Each subject performed three times Running-based Anaerobic Sprint Test (RAST) with intervals of 1 hour. Max power, Minimal power (Min power) and Fatigue index were calculated for each participant. Results: There was a significant decrease in Max and Min power in P group in time series (P< 0.05). Furthermore, regarding the Max and Min power, there was significant difference between P and GM group in third bout indicating stronger influence of combination of maltodextin and glutamine in comparison with pure consumption of glutamine and maltodextrin (P< 0.05). Conclusions: It seems acute supplementation of glutamine and maltodextrin combination, 2 hours before exercise is more efficient in storing glycogen than consumption of a pure carbohydrate or glutamine and consequently prevents decline of anaerobic power in repeated bouts of RAST protocol better than pure maltodextrin or glutamine. Keywords: Carbohydrate, Peptide, Maximal Power, Minimal power, Fatigue index. |
