Abstract
Intense dance training leads to inflammation, which may impair the health and performance of the practitioners. Herein, we evaluate the effect of a single street dancing class on the profile of muscle enzymes, lymphocyte activation, and cell surface CD62L expression. We also investigated the correlation between muscle enzymes, adhesion molecules, and lymphocyte activation in dancers. Fifteen male participants (mean ± standard error: age 22.4 ± 1.08 years, body mass index 24.8 ± 0.69 kg/m2, body fat 12.3 ± 1.52%), who were amateur dancers, had blood samples collected previously and subsequent to a high-intensity street dance class. After the class, dancers showed an increase in total lymphocyte count (2.0-fold), creatine kinase (CK)-NAC (4.87%), and CK-MB (3.36%). We also observed a decrease (2.5-fold) in reactive oxygen species (ROS) produced by lymphocytes, under phorbol myristate acetate-stimulated environments. Following the dance class, CD62L expression in lymphocytes decreased (51.42%), while there was a negative correlation between the intensity of the exercise and CD62L expression (r = -0.73; p = 0.01). Lymphocytes were less responsive to stimuli after a single bout of street dancing, indicating transient immunosuppression.
Highlights
Street dance involves explosive movements, jumps, accelerations, and decelerations, resulting in acute fatigue and decreased performance in dancers [1]
Our study was the first to report that lymphocyte production of reactive oxygen species (ROS), after phorbol myristate acetate (PMA) stimuli, and lymphocyte CD62L expression was lower in dancers after a single class
Lymphocyte CD62L expression was decreased and found at low levels after the class, and this may impair the trafficking of leukocytes in dancers
Summary
Street dance involves explosive movements, jumps, accelerations, and decelerations, resulting in acute fatigue and decreased performance in dancers [1]. High-intensity street dance exercise results in neutrophil dysfunction, accompanied by increased pro-inflammatory cytokines [2]. One approach used to explore lymphocyte distribution is the assessment of cell surface adhesion molecule expression. Such analyses can reveal the trafficking patterns of cells mobilized into the bloodstream during physical exercise [5, 6].
