Abstract
Objective: The new adipokine, which is asprosin, affects glucose release from the liver to the blood, and thus, influences exercise metabolism. This is the first study assessing whether single anaerobic exercise affects asprosin secretion in women and men.Methods: 10 men and 10 women (aged 21.64 ± 1.22 and 22.64 ± 1.49, respectively) performed a single 20-s bicycle sprint. Blood samples were collected before exercise and in the 3′, 15′, 30′, and 60′ of recovery, and 24 h after competition.Results: Only in women did asprosin (P = 0.001) (15′, 30′, 60′, and 24 h after exercise) and irisin (P < 0.001) (15′, 30′, and 60′) concentrations increase. Leptin, however, decreased (P = 0.001) at 3′, 15′, and 30′ in women. There was an increase in interleukin-6 (P < 0.001) at 3′, 15′, 30′, and 60′ of recovery in men, at 15′, 30′, 60′, and 24 h of recovery in women, along with a simultaneous decrease in interleukin-1β (P < 0.001) at 15′, 30′, and 60′ of recovery in men, and at 15′ and 30′ of recovery in women (r = -0.35, P < 0.001). There was a positive correlation between asprosin and adiponectin and a negative one between asprosin and leptin. The increase in irisin concentration at 30′ of recovery was positively correlated with the increase in asprosin concentration and percentage fat content, while being negatively correlated with total and lean body mass (LBM).Conclusion: The single anaerobic effort induced an increase in asprosin and irisin secretion while reducing leptin secretion in women. Adipocytokine concentration changes are inter-related. Regardless of sex, anaerobic efforts induce anti-inflammatory effects.
Highlights
Short, dynamic anaerobic exercise, such as a 20-s bicycle sprint, induces enormous multidirectional biochemical changes, including metabolic, hormonal, and immunological ones
It has been demonstrated that a single anaerobic exercise increases the nuclear factor κB (NF-κB) activity in the nuclei of peripheral blood mononuclear cells, which is accompanied by the degradation of its inhibitor (IκB) (Cuevas et al, 2005)
Adipocytokines The asprosin concentration in women at 3 after exercise was comparable (P > 0.05) to baseline (0 ), and increased, attaining its highest value at 30, which was significantly higher compared to the value at 3 (P = 0.009) and 15 (P = 0.017)
Summary
Dynamic anaerobic exercise, such as a 20-s bicycle sprint, induces enormous multidirectional biochemical changes, including metabolic, hormonal, and immunological ones. An anaerobic effort may cause an increase in adipocytokine and myokine concentration in the blood which are involved in the regulation of resting and exercise-related metabolic processes (Bostrom et al, 2012; Li et al, 2017). They affect energy balance and anti-inflammatory activity (Cao, 2014; Li et al, 2017)
