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.</p> <p><strong>Materials and Methods:</strong> In this quasi-experimental study, 30 students (mean age 17<span dir="RTL">.</span>1&plusmn;84<span dir="RTL">.</span>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.</p> <p><strong>Results:</strong> 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 (<em>P</em>=0<span dir="RTL">.</span>009), this was not the case for red blood indexes.</p> <p><strong>Conclusions:</strong> Interval exercises along with iron supplementation caused an increase in aerobic power and some hematologic indexes.</p> تمرین, شاخص های خونی, آهن Exercise‚ Hematologic index‚ Iron 142 148 http://feyz.kaums.ac.ir/browse.php?a_code=A-10-1929-2&slc_lang=fa&sid=1 Fatemeh Omidali فاطمه امیدعلی omidali.fatemeh@yahoo.com 2900319475328460017805 2900319475328460017805 Yes Department of Physical Education‚ Ayatollah Boroujerdi University, Boroujerd, I.
