Effect of interval exercise with iron supplementation on aerobic power and some hematologic indexes among the 15-18 years old boys

Aerobic fitness is an index of pulmonary, cardiovascular function and haematological components and relevant to the delivery of oxygen. The aim of present study was to evaluate the effect of interval exercise with iron supplementation on aerobic power and some hematologic indexes among the15-18 years old boys.
In this quasi-experimental study, 30 students (mean age 17.1±84.16) were participated in an exercise program (6 weeks, 3 sessions per week). The participants were randomly divided into three groups: Control; Exercise and exercise iron supplementation groups. Iron supplementation group was administered a daily supplement of iron tablet. Using a before-after design, bulk-field test and blood sampling the data were analyzed.
The results showed no significant difference among the groups. However, using a 6-week training program in Exercise and Exercise Iron supplementation group compared to the Conrol showed a significant difference for aerobic power; ferritin; transferrin and iron. No significant change was seen for hemoglobin, hematocrit and red blood cells. While in exercise group, interval exercise caused a significant increase in aerobic power (P=0.009), this was not the case for red blood indexes.
Interval exercises along with iron supplementation caused an increase in aerobic power and some hematologic indexes.
