The impact of high-intensity laser therapy on oxidative stress, lysosomal enzymes, and protease inhibitor in athletes.

The impact of high-intensity laser therapy on oxidative stress, lysosomal enzymes, and protease inhibitor in athletes. Chin J Physiol. 2019 Nov-Dec;62(6):273-278 Authors: Sielski Ł, Sutkowy P, Katarzyna PO, Woźniak A, Skopkowska A, Woźniak B, Czuczejko J Abstract The aim of the study was to assess the effect of one session of high-intensity laser therapy (HILT) on the levels of selected oxidative stress parameters, lysosomal hydrolases, and anti-inflammatory serine protease inhibitor in the peripheral blood of amateur athletes with torn or pulled tendons of the ankle or the knee joint. The group of injured athletes comprised 16 males and females aged 16.3 ± 1.3 years, while the control group of 14 healthy, noninjured amateur athletes of both sexes (controls; age 17.4 ± 4.6 years). Material for the study was peripheral blood taken at three study time points: Immediately before, 30 min after, and 24 h after HILT intervention. In plasma and erythrocytes, thiobarbituric acid reactive substances (TBARSpl and TBARSer, respectively) were determined. In erythrocytes, the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were measured. In serum, the activity of acid phosphatase (AcP), arylsulfatase (ASA), cathepsin D (CTS D), and α1-antitrypsin (AAT) were determined. Among oxidative stress parameters, only the CAT activity significantly decreased 24 h after HILT compared to measurement 30 min aft...
