Female collegiate field hockey players showed decreases in iron stores (as measured by serum ferritin) in each of 3 successive fall seasons studied. After the 1st season of regular play, a decrease (25-23 ng/ml was observed, but measurements after post-season tournament play for the 2nd and 3rd seasons showed significant (P less than 0.05) decreases of 37% (30-19 ng/ml) and 30% (24-17 ng/ml), respectively. The added stress of tournament play appeared to cause additional loss of reserve iron nearly as great as that experienced during early season training. After several years of play, serum ferritin levels in these athletes were frequently between 10 and 20 ng/ml, with the lowest levels occurring in 3rd- and 4th-year athletes. Those women who participated in all 3 years had progressively declining serum ferritin levels throughout their collegiate careers. Participation in collegiate field hockey jeopardizes body iron stores, and iron reserves tend to become progressively more depleted after successive seasons of competition.
在连续研究的三个秋季赛季中，女子大学曲棍球运动员的铁储备（通过血清铁蛋白测量）均有所下降。在第一个常规赛季后，观察到铁储备下降（从25降至23 ng/ml），但在第二个和第三个赛季的季后赛之后，测量结果显示显著下降（P小于0.05），分别下降了37%（从30降至19 ng/ml）和30%（从24降至17 ng/ml）。季后赛增加的压力似乎导致储备铁额外流失，几乎与赛季初期训练期间的流失量一样大。经过数年的比赛，这些运动员的血清铁蛋白水平经常在10至20 ng/ml之间，最低水平出现在三年级和四年级运动员中。那些参加了所有三年比赛的女性在整个大学生涯中血清铁蛋白水平逐渐下降。参加大学曲棍球运动会危及身体的铁储备，并且在连续几个赛季的比赛后，铁储备往往会逐渐消耗得更多。
