Description

To evaluate the effects of long-term voluntary resistance exercise (climbing) compared with aerobic exercise (swimming) on iron status in severely (4mg Fe/kg diet) and mildly (18-29mg Fe/kg diet) iron deficient rats, we trained male Wistar rats for 8 weeks to climb a wire-mesh tower (φ20cm×200cm, CLIMB) and swim in a plastic pool (φ50cm×50cm, SWIM). These were compared to sedentary (SED) rats. After the experimental period, blood hemoglobin level, hematocrit, plasma iron concentration and transferrin saturation were significantly lower in the 4mg Fe/kg diet fed rats than in the 40mg Fe/kg diet fed rats for SED, SWIM and CLIMB groups (experiment 1). Hemoglobin and hematocrit levels were significantly higher in the CLIMB group than the SED group in 4mg Fe/kg diet fed rats (experiment 1). On the other hand, neither exercise affected iron status in mildly iron deficient rats (experiment 2). Iron content in the liver, spleen, heart and kidney rdecreased with iron levels. These results suggest that long-term resistance exercise inproves iron status in severely iron deficient rats more than aerobic exercise, probably due to an increase in the capacity for heme biosynthesis. Resistance exercise may be a useful therapy for iron deficient anemia.
