Forty-eight hours after the first concert, they underwent a magnetic roller training session to get tested and familiarized, and again 48 hours later, they conducted 2-to-4 bouts of 30-second all-out workout, interspersed with 4 minutes of recovery, between the two concerts. Self-reporting methods (STAI, CSAI-2R) and physiological methods (Heart Rate Variability) were used to test anxiety reduction.<br> <strong>Results. </strong>Pre-post exercise comparisons revealed a significant reduction (p < 0.05) in both questionnaires. Regarding heart rate variability, Friedman Anova tests revealed also significant differences in Low Frequency (LF; p < 0.05), Low Frequency/High Frequency ratio (LFHF; p < 0.01), Root Mean Square of successive normal R-R intervals (RMSSD; p = 0.01), Detrended Fluctuation Analysis (DFA1; p < 0.01) and Sample Entropy (SampEn; p < 0.01) after HIIT.<br> <strong>Conclusion. </strong>After the training, the HRV indices&rsquo; improvement could confirm the hypothesis of parasympathetic reactivation and a better vagal balance as much in the last moment as during the performance. Acute high-intensity exercise may be an efficient solution in the short term for the anxiety problems that musicians suffer in their intense careers.</div> Heart Rate, Mental Health, Psychopathology, Psychophysiology 0 0 http://aassjournal.com/browse.php?a_code=A-11-1897-1&slc_lang=en&sid=1 Cristina Blasco-Lafarga M.Cristina.Blasco@uv.es 100319475328460011411 100319475328460011411 No Sport Performance and Physical Fitness Research Group UIRFIDE, University of Valencia, Carrer de Gascó Oliag, 3, 46010, Valencia, Spain.
