The effect of cold-water bath on postexercise activity of α1-antitrypsin and selected lysosomal enzymes in healthy men’s blood – preliminary study
Journal Title: Medycyna Sportowa - Year 2017, Vol 33, Issue 3
Abstract
Background. The aim of the study was to determine the effect of winter bath after physical exercise on the activity of α1-antitrypsin (AAT) and selected lysosomal enzymes: arylsulfatase (ASA), acid phosphatase (AcP) and cathepsin D (CTS D) in healthy males’ blood. Material and methods. 22 males participated in two session of aerobic physical exercise. After one session the subjects rested in room temperature while after the other session they bathed in cold water (3 minutes, 8ºC; experiment 2). During each stage they had blood taken from the basilic vein prior to physical exercise and 2 and 20 minutes after the exercise. The activity of AAT, ASA, AcP and CTS D was assayed in blood serum. The obtained results were subjected to statistical analysis using ANOVA test. The changes at the level p<0.05 were regarded as statistically significant. Results. A statistically significant increase in AcP and CTS D activity was found as well as a decrease in AAT activity following physical exercise and resting at room temperature as compared with the activity of the assayed parameters prior to physical exercise. Conversely, no statistically significant differences in protease inhibitor activity (AAT) and lysosomal enzyme activity were noted after physical exercise and cold water bath as compared with their activity measured prior to 30-minute long physical exercise. Conclusions. Hot water bath applied after physical exercise increases the stability of lysosomal membranes and may result in a decrease of post-exercise muscle damage.
