Interrelationships among food intake, somatic traits, and physical fitness in 10.5- to 15.5-year-old children from eastern Poland

Article Abstract:

Research supports the theory that well-nourished children are more advantaged physically than those who are poorly nourished. Studies of Polish children between the ages of 10.5 and 15.5 show that dietary quality is an important factor in improving somatic development, contributing to physical fitness. Energy intake, however, does not account for all variances in physical fitness between the two groups of children.

Iron status in female endurance athletes and in non-athletes

Article Abstract:

This article compares the iron status of female athletes and non-exercising control subjects and investigates factors involved in iron deficiency. Results indicate that iron deficiency was more prevalent in control subjects and that the primary causes of iron depletion include menstrual bleeding and inadequate intake of dietary iron.

The assessment of frequency of iron deficiency in athletes from the transferrin receptor-ferritin index

Article Abstract:

This article uses a hematological index to examine the incidence of iron deficiency in a sample of athletes. Findings indicate that the transferrin receptor-ferritin index is a useful tool in evaluating iron status and that iron deficiency is more prevalent and profound among women athletes.
