Introduction
A single physical exertion rapidly evokes cardiovascular changes. Owing to the body’s ability to maintain homeostasis, it is able to respond to increased metabolic demand. The aim of this study was to assess the effect of a single physical exercise performed at low temperatures (–10°C) on changes in blood serum protein profile, and to compare the results with a control group that performed the same activity in atmospheric conditions of 18°C.
Material and methods
The participants of the study were divided into two groups: Group 1 (study group, n = 15) ran in a thermoclimatic chamber at an air temperature of –10°C, and Group 2 (control, n = 15) ran outdoors at an air temperature of 18°C. In group 1, the subjects (n = 15) performed a 5-minute warm-up in standing position, which was carried out before entering the thermoclimatic chamber of the Laboratory of Technoclimatic and Working Machines (LBT&MR) of the Faculty of Mechanical Engineering at Krakow University of Technology (Poland), at an air temperature of –10°C, and then participated in a beep test endurance shuttle run conducted until exhaustion under the supervision of a trainer. In Group 2 (n = 15), the subjects performed the same test protocol, but outdoors, with an air temperature of 18°C.
Results
Blood samples were collected from the subjects before entering the thermal climate chamber and after leaving it (fasting, from the antecubital vein, volume 5 ml, into tubes) by a qualified nurse. The blood samples were analysed in the Diagnostyka S.A. laboratory in Krakow, Poland for protein electrophoresis.
Conclusions
Prevailing temperature conditions during physical exercise had no substantial influence on the changes in analysed the blood parameters. An exception was β1-globulin [%], in this instance, a substantial impact of the experimental factor (air temperature –10°C) was shown, indicating that the increase in β1-globulin in low temperatures is primarily relative, associated with haemoconcentration rather than an actual increase in protein synthesis.
