Serum vaspin and chemerin changes in response to combat physical fitness test in military forces

The study aimed to investigate serum vaspin and chemerin changes in response to combat physical fitness tests in military forces. In a semi-experimental design with pretest and posttest, twenty volunteers were engaged to participate in the study. Combat Physical Fitness Test consisted: (1) 25-yard(yd) sprint to J-hook, to 25-yd crawl, and 25-yd run through cones to 75-yd line; split (2) 75-yd casualty drag; split (3) ammo can run to grenade toss (75-yd); (4) ammo can run to end (75-yd); and (5) 650-yard endurance run. Pre-test and the post-test blood sample was gained. The data were analyzed by SPSS version 24. Serum chemerin did not change significantly compared to the pre-test whereas Serum vaspin was significantly higher after the test (p = 0.018). Afterward, a direct correlation was observed between serum chemerin and serum vaspin (p = 0.034, r=0.335). It is suggested that serum vaspin is responsive to short-term maximal power output activity required in the combat fitness test and positively correlates with chemerin. However, it appears that 3 to 4 minutes of high-intensity exercise induce comparatively moderate post-exercise serum vaspin increment, which appears to be inadequate to stimulate chemerin secretion.
