AB  - The main aim of our study was to determinate whether a repeated bout (RB) (vs. 
      first bout [FB]) of sprint interval cycling exercise (SIE) is sufficient to 
      mitigate SIE-induced psychological and physiological biomarker kinetics within 48 
      h after the exercise. Ten physically active men (age, 22.6 +/- 5.2 years; VO(2)max, 
      44.3 +/- 5.7 ml/kg/min) performed the FB of SIE (12 repeats of 5 s each) on one day 
      and the RB 2 weeks later. The following parameters were measured: motor 
      performance (voluntary, electrically induced and isokinetic skeletal muscle 
      contraction torque, and central activation ratio [CAR]); stress markers 
      [brain-derived neurotrophic factor (BDNF), cortisol, norepinephrine, and 
      epinephrine]; inflammatory markers (IL-6, IL-10, and TNF-alpha); metabolic markers 
      (glucose and lactate); muscle and rectal temperature; cycling power output; and 
      psychological perceptions. The average cycling power output and neuromuscular 
      fatigue after exercise did not differ between the FB and RB. There were 
      significant decreases in cortisol and BDNF concentration at 12 h (P < 0.05) and 
      24 h (P < 0.001) after the FB, respectively. The decrease in cortisol 
      concentration observed 12 h after exercise was significantly greater after the RB 
      (P < 0.05) than after the FB. The immune-metabolic response to the RB (vs. FB) 
      SIE was suppressed and accompanied by lower psychological exertion. Most of the 
      changes in psychological and physiological biomarkers in the FB and RB were 
      closely related to the response kinetics of changes in BDNF concentration.
