Vitamins, Minerals and Race Performance in Ultra-Endurance Runners-Deutschlandlauf 2006
極限跑者維生素及礦物質攝取及競賽表現－Deutschlandlauf 2006
摘要
本研究想探討在一個多階段極限耐力賽跑前，以補充劑的形式攝取維生素和礦物質的效果和這樣的補充對於競賽上的影響。參加德國Deutschlandlauf2006的運動員都需要從德國北方(KapArkona-Rügen)橫跨到南方(Lörrach)，進行超過1200公里，17個連續階段的賽跑。共20位男性跑者(46.2±9.6歲,71.8±5.2公斤,179±6公分,BMI=22.5±1.9kg/m2)完成關於比賽前四週攝取維生素和礦物質補充劑的問卷。比較有規律攝取補充劑和沒有攝取補充劑的運動員之競賽表現。賽跑前四週有9位(45%)補充維生素和有12位(60%)補充礦物質。不管是攝取維生素或礦物質補充劑的運動員完成比賽並沒有比未補充的運動員來得快。所以結論是對於Deutschlandlauf2006超過1200公里且17個連續階段的競賽而言，比賽前四週有規律攝取維生素和礦物質補充劑的運動員，完成比賽的速度並沒有快過於未補充的運動員。

We investigated the effect of pre-race intake of vitamins and minerals, in the form of supplementation, before a multi-stage ultra-endurance run and their effect on race performance. At the Deutschlandlauf 2006 in Germany, where athletes had to run across Germany from the north (Kap Arkona-Rügen) to the south (Lörrach) over 1,200 km within 17 consecutive stages, twenty male ultra runners (46.2 ± 9.6 years, 71.8 ± 5.2 kg, 179 ± 6 cm, BMI 22.5 ± 1.9 kg/m2) completed a questionnaire about their intake of vitamin and mineral supplements in the four weeks before the race. Race performance of athletes with- and athletes without regular intake of these supplements were compared. In the four weeks before the run, nine runners (45%) ingested vitamin- and twelve athletes (60%) mineral supplements. Athletes with an intake of vitamins (152.8 ± 14.1 h versus 160.6 ± 14.6 h, p ＞ 0.05) and minerals (151.6 ± 14.5 h versus 165.3 ± 10.8 h, p ＞ 0.05) finished the race no faster than athletes without an intake of vitamins and minerals. We concluded that in the Deutschlandlauf 2006 of over 1,200 km within 17 consecutive stages, athletes with a regular intake of vitamin and mineral supplements in the four weeks before the race finished the competition no faster than athletes without an intake of vitamins and minerals.
