The present data article aims at investigating the muscular levels of Irisin, FNDC5, and UCP1 in male Wistar rats during the aerobic exercise with or without calorie restriction (CR). Twenty four, 8-week-old male Wistar rats (190±16 g) were selected and purchased for the research. After obesity induction by high-fat diet, the animals were randomly divided into three groups: exercise EX (n = 8), EX-CR (n = 8) and CO as control (n = 8). EX exercised 6 sessions per week and EXCR exercise 3 sessions + 3 days caloric restriction per week. The Irisin (Cat.No:CK-E91266 & Intra-Assay: CV<10%), FNDC5 (Cat.No:CK-E91393 & Intra-Assay: CV<10%) levels were assessed by the special Rat ELISA Kit (EASTBIOPHARM, China, under licensed by the United States). Muscular Irisin concentrations in EX group were higher than other groups. In addition, FNDC5 concentrations in EX group was higher than those in other groups.

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.
