“…These observations underline the importance of using a resting session when evaluating the effect of exercise on leptin concentrations to control for fasting- and/or circadian rhythm-induced leptin reductions 71. Our group showed72 that short supramaximal exercise performed by physically active males and females did not modify plasma leptin and insulin concentrations but increased cortisol concentrations. Under these conditions, leptin production seemed insensitive to exercise (≥60 min): serum leptin concentrations were analysed after three competitive endurance races performed by 45 males who participated in one of three competitive endurance races: a half-marathon run (estimated energy expenditure “EE” ~1400 kcal), a ski-alpinism race (estimated EE ~5000 kcal), and an ultramarathon race (estimated EE ~7000 kcal) 73.…”

Leptin and adiponectin represent two newly discovered adipose tissue derived hormones; that are both associated with health status and glucose and free fatty acid (FFA) metabolism. Moreover, acute and chronic exercises affect body composition, carbohydrate and lipid metabolism. It is thus interesting to evaluate the effects of physical exercise and training on leptin and adiponectin levels. It seems that leptin concentration is not modified after short-term exercise (<60 min) or exercise that generates an energy expenditure lower than 800 kcal. Leptin levels decrease after long-term exercise (> or =60 min) stimulating FFA release, or after exercise that generates energy expenditure higher than 800 kcal. Adiponectin concentration presents a delayed increase (30 min) after short-term intense exercise (<60 min) performed by trained athletes. For adiponectin, limited data suggest that adiponectin concentration presents a delayed increase (30 min) after short-term intense exercise (<60 min) performed by trained athletes. It seems that adiponectin concentrations do not change in response to long-term exercise (> or =60 min). Short-term training (<12 weeks) and long-term training (> or =12 weeks) show contrasting results regarding leptin and adiponectin. Most training studies which improve fitness levels and affect body composition could decrease leptin and increase adiponectin concentrations.

“…Thus, Bouassida et al [291] did not report a decrease in plasmatic leptin levels in a sample of 5 physically active men and 12 women after performing 45 s of exercise at an intensity of 120% of maximum aerobic power peak. In this same line, Zoladz et al [292] also did not observe changes in leptin concentrations in a sample of eight physically active men after performing a maximal and incremental cycle ergometer protocol without fasting and a submaximal incremental cycle ergometer protocol under fasting conditions.…”

Adipokines are cell-signaling proteins secreted by adipose tissue that has been related to a low-grade state of inflammation and different pathologies. The present review aims to analyze the role of adipokines in health and disease in order to understand the important functions and effects of these cytokines. For this aim, the present review delves into the type of adipocytes and the cytokines produced, as well as their functions; the relations of adipokines in inflammation and different diseases such as cardiovascular, atherosclerosis, mental diseases, metabolic disorders, cancer, and eating behaviors; and finally, the role of microbiota, nutrition, and physical activity in adipokines is discussed. This information would allow for a better understanding of these important cytokines and their effects on body organisms.

“…Among the studies conducted to examine the effect of acute exercise on leptin hormone concentration, we found that chromium picolinate supplement taken with exercise reduces serum leptin concentration; Sari et al, (2007), Jurimäe J. and Jürimäe T., (2005), Legakis, (2004), Zafeiridis et al, (2003), Bouassida et al, (2004), Zaccaria et al, (2002), Duclos et al, (1999), Olive and Miller, (2001), reported supportive reductions. Among the studies conducted to examine the effect of chronic exercise on leptin hormone concentration; Ozcelik et al, (2004), Polak et al, (2006), Miyatake et al, (2004) found data supporting the leptin hormone concentration result we obtained.…”

This work; It is aimed to adapt the Effect of Chromium Mineral Supplement on Serum Irisin, Leptin and Ghrelin Hormone Levels to Exercise Trainings. For this purpose; A total of 28 male rats of eight weeks old Wistar Albino were included in the study and randomly divided into four groups. The control group (n=7) who continued to be fed with a daily diet and waited for eight weeks without any supplementation; The exercise group in which the treadmill exercise was performed at a speed of 15 m/min on the treadmill for five days for eight weeks (n=7); supplementation group (n=7) given chromium picolinate by gavage method (8 μg / kg/day) once a day for eight weeks in addition to daily dietary nutrition; In addition to dietary nutrition, a single dose (8 μg/kg/day) chromium picolinate was given by gavage for eight weeks and supplemented + exercise group (n=7) in which 20 min/day treadmill exercise was performed for eight weeks. At the end of the studies, which lasted for a total of 10 weeks with two weeks of adaptation exercises, blood samples were taken with the decapitations of the rats. Irisin, leptin and ghrelin analyzes in blood samples were studied by preparing them according to the kit procedure with the elisa method. According to the data we obtained, the normality homogeneity test was applied and it was determined that the data were normally distributed. As a result, one way anova test and paired sample t test were applied from parametric tests (p<0.05 statistically significant difference was accepted) and tukey test was applied to determine the difference between groups. SPSS-21 package program was used in the analysis of the data (p< 0.05 was considered a statistically significant difference). Correlation test was used to determine the relationship between variables. As a result, treadmill exercise applied at a speed of 20 minutes, 15 km/h, 5 days a week for eight weeks, and chromium mineral supplementation decreased the hormone level of ghrelin, thus reducing the need for food intake and less energy consumption. It was found that the use of chromium picolinate alone had a lowering effect on the leptin hormone, and that it also reduced the leptin hormone level in long-term exercise, that the combination of chromium picolinate supplement and exercise further reduced the already low leptin level compared to the chromium group and exercise group. We found that the level was significantly reduced.
