Effect of single bout downhill running on the serum irisin concentrations in rats.
This study aimed to characterize the effect of different running modes on serum irisin concentrations in rats. A total of 18, 10-week-old rats were divided into three groups; control group, 16° uphill running group (concentric exercise; CON) and, -16° downhill running group (eccentric exercise; ECC). The running group's rats ran on the inclined treadmill at 16 m/min, for a total of 90 min. Blood was drawn from the rats, 48 h after running, after which the rats were anesthetized. The serum concentrations of irisin were measured using enzyme-linked immunosorbent assays. Vastus intermedius was collected for immunohistochemical analysis. After multiple comparisons, the ECC showed a significantly high serum irisin concentration (ECC: 28.42 ± 6.31 ng/ml, CON: 21.27 ± 3.03 ng/ml) and a larger irisin antibody reactive cross-sectional area in vastus intermedius compared to the CON (p < 0.05). This is the first study to reveal that single bout downhill running increases serum irisin concentrations in rats.
期刊介绍：
Growth Factors is an international and interdisciplinary vehicle publishing new knowledge and findings on the regulators of cell proliferation, differentiation and survival. The Journal will publish research papers, short communications and reviews on current developments in cell biology, biochemistry, physiology or pharmacology of growth factors, cytokines or hormones which improve our understanding of biology or medicine. Among the various fields of study topics of particular interest include: •Stem cell biology •Growth factor physiology •Structure-activity relationships •Drug development studies •Clinical applications
