J Nutr 131:676S-688S; discussion 688S-690S. 2001..This may also extend to the segment of the population experiencing IDNA in whom the effects on work capacity may be more subtle, but the number of individuals thus affected may be considerably more than those experiencing IDA... - Marginal iron deficiency without anemia impairs aerobic adaptation among previously untrained womenThomas Brownlie
Division of Nutritional Sciences, Cornell University, Ithaca, NY 14853, USA
Am J Clin Nutr 75:734-42. 2002..CONCLUSIONS: Our findings strongly suggest that iron deficiency without anemia but with elevated sTfR status impairs aerobic adaptation among previously untrained women and that this can be corrected with iron supplementation... - Iron depletion without anemia and physical performance in young womenY I Zhu
Division of Nutritional Sciences, Cornell University, Ithaca, NY 14853, USA
Am J Clin Nutr 66:334-41. 1997..Therefore, reduction of VO2max in nonanemic women with iron depletion was likely caused by factors related to reduced body iron storage but was unrelated to decreased oxygen-transport capacity of the blood... - Altered metabolic response of iron-depleted nonanemic women during a 15-km time trialY I Zhu
Division of Nutritional Sciences, Cornell University, Ithaca, New York 14853, USA

Division of Nutritional Sciences, Cornell University, Ithaca, NY 14853, USA
Am J Clin Nutr 79:437-43. 2004..0 mg/L. However, the effect of transferrin receptor status on adaptation in endurance capacity after aerobic training in these subjects has not been fully explored... - Accuracy and reliability of the ParvoMedics TrueOne 2400 and MedGraphics VO2000 metabolic systemsScott E Crouter
Division of Nutritional Sciences, Cornell University, 279 MVR, Ithaca, NY 14853, USA
Eur J Appl Physiol 98:139-51. 2006..The VO2000 portable metabolic system was less reliable for measuring VO2 and VCO2 and generally overestimates VO2 at most cycling work rates. Further research is needed to confirm the results found with the VO2000... - Hemoglobin correction factors for estimating the prevalence of iron deficiency anemia in pregnant women residing at high altitudes in BoliviaJ H Cohen
Cornell University, Division of Nutritional Sciences, Ithaca, New York, USA

Department of Anthropology, Cornell University, Ithaca, New York, USA
Am J Phys Anthropol 113:169-81. 2000..Results from this study are compared to similar studies conducted with Tibetan natives, and are interpreted in light of recent quantitative genetic analyses conducted in both the Andes and Himalayas... - Effect of developmental and ancestral high-altitude exposure on VO(2)peak of Andean and European/North American nativesT D Brutsaert

Int J Vitam Nutr Res 77:199-204. 2007..Throughout the course of conducting a large feeding trial in convents in Manila, we collected weighed food-intake data and have the opportunity to directly compare the performance of these prediction equations... - Absence of work efficiency differences during cycle ergometry exercise in Bolivian AymaraTom D Brutsaert
Department of Anthropology, The University at Albany, SUNY, Albany, NY 12222, USA
High Alt Med Biol 5:41-59. 2004..In sum, these results provide no support for the hypothesis of energetic advantage during submaximal work in Andean HA natives. A review and analysis of the literature suggest that the same is true for HA natives in the Himalayas... - Last menstrual period provides the best estimate of gestation length for women in rural GuatemalaLynnette M Neufeld
