تاثير مصرف كوتاه مدت تيامين پيرو فسفات بر توان هوازي و بي‌هوازي در دختران فوتباليست

The effect of short term TPP supplementation on aerobic and anaerobic power in girl soccer players

چكيده: زمينه و هدف: تيامين نقش مهمي‌را به عنوان كوآنزيم در سوخت و ساز انرژي و حفظ عملكرد سلول‌هاي عصبي ايفا مي‌كند. هدف از اين تحقيق بررسي تاثير مكمل دهي كوتاه مدت تيامين پيرو فسفات بر توان هوازي و بي هوازي در دختران فوتباليست بود. روش بررسي: اين مطالعه كارآزمايي باليني دو سوكور و متقاطع بر روي 20 دختر جوان فوتباليست شهرستان ني‌ريز انجام شد. آزمودني‌ها بعد از قرار گرفتن در گروه مكمل و دارونما به ترتيب به مدت يك هفته مكمل تيامين و دارونما را مصرف كردند، كه روزانه در دو نوبت 8 صبح و 4 عصر به ميزان 100 ميلي گرم در هر نوبت مكمل يا دارونما دريافت كردند. داده‌ها با استفاده از آزمون آناليز واريانس يك طرفه با اندازهگيري تكراري تجزيه و تحليل شد. يافته‌ها: افزايش معني‌داري در ميزان حداكثر اكسيژن مصرفي(70/2± 65/47) و مسافت و زمان پيموده(68/0± 21/16) شده تا پايان فعاليت در گروه مكمل نسبت به گروه دارونما مشاهده شد (016/0p < ) .ميانگين و انحراف معيار اوج توان بي‌هوازي، ميانگين توان بي‌هوازي و شاخص خستگي در گروه مكمل به ترتيب 02/75± 95/490 ، 41/86± 48/385، 05/12± 64/29 به دست آمد و اختلاف معني‌داري بين اوج توان بي‌هوازي، ميانگين توان بي‌هوازي و شاخص خستگي بين گروه‌ها مشاهده نشد. نتيجه‌گيري: مصرف مكمل تيامين در دختران فوتباليست مي‌تواند توان بي‌هوازي را بهبود بخشيده، خستگي را كاهش و مصرف اكسيژن را افزايش دهد.

Background & aim: Vitamin BI(thiamine) plays an important role as a coenzyme in energy metabolism and in the maintenance of nerve cell function. The purpose of this study was to investigate the effect of short – term supplementation of thiamin pyrophosphate on the aerobic and anaerobic power in girl soccer players. Methods: The study was carried out as a double – blind cross-over clinical test. The statistical society of this research included young girl football players of Neiriz city, who regularly took part in sport activities and training. Among them, 16 people were randomly chosen to participate as samples in the execution of this project. For the initial evaluation of variables under study, two days prior to the supplementation period, the subjects, before being put in the supplemented and placebo groups underwent Bruce and Rest test. At first the Rest test was carried of and the Bruce test followed two hours later. After being assigned to supplement and placebo groups, the subjects took thiamine and placebo for a week. Twice daily, they received 100 mg. Of thiamine supplementation or placebo (at 8 am. And 4 pm.). In order to study the changes and analysis of the data, the one – way variance analysis test with repeated measurement was applied. A significant level was set of less than 0/05. Results: A significant increase in the amount of maximal oxygen intake?(47/65 ± 2/70 ) and the travelled distance and time till?(16/21 ± 0/68) the end of the activity was observed in the supplemented group(P < 0/016). Mean peak aerobic power, anaerobic power and fatigue index group (s) to supplement the 75/02 ± 490/95, 86/41 ± 385/48, 12/05 ± 29/64 respectively and compared to the between the peak and the average anaerobic power, fatigue index and between the groups. Conclusion: Thiamine supplementation, Could lead to further decomposition of pyruvate, Aerobic activity increases cellular metabolism and the Krebs cycle routes, Resulting in increased oxygen consumption is. Key Words: Thiamine pyrophosphate, anaerobic power, maximal oxygen consumption, fatigue index.
