Given the significant prevalence of low Hb (15.5%) and Ht (23.6%) in our sample, implying the presence of anemia among 15.5% to 23.6% of the participants, dietary modifications, particularly focusing on iron-rich foods and optimizing iron absorption, can significantly improve participants’ iron status and potentially enhance their performance [31,32]. This evidence concerns the gene GSTM1 and anemia (phenotype).
