Key result
A high-intensity interval training session in trained swimmers significantly increased blood lactate, cortical arousal, and perceived exertion (p<0.05), while decreasing HRV parameters.

Does a high intensity interval training session alter acute psycho-physiological responses in trained swimmers?
High intensity interval training sessions induce significant acute psycho-physiological stress and sympathetic nervous system modulation in trained swimmers.
The aim of the present research was to analyze the acute psycho-physiological response during a high intensity interval training session of trained swimmers. We analyzed blood lactate concentration, heart rate, heart rate variability (HRV), arms isometric strength, rating of perceived exertion (RPE) and cortical arousal pre and post a high intensive-interval training (HIT) session in14 trained swimmers (16.2±2.6 years 169.1±10.2 cm 61.3±9.9 kg). HIIT session consisted in: 4×10 m tethered swimming resting 90 s between sets, 3 min rest, 16×25 m maximum speed resting 30 s between sets. Blood lactate concentration, cortical arousal and rating of perceived exertion significantly increased (p<0.05) after HIIT. HRV parameters of SDSD, SDNN, NN50, pNN50 and RMSSD significantly decreased after HIIT that showed an increase in sympathetic nervous system modulation. Results obtained showed the high impact of HIT sessions on the swimmers organism, which may be the cause of adaptation in this low volume training sessions.

Clemente‐Suárez et al. (2016) conducted an observational in Trained swimmers (n=14). High intensity interval training (HIIT) session vs. Pre-training baseline was evaluated on Acute psycho-physiological response (blood lactate, HR, HRV, strength, RPE, cortical arousal) (p=<0.05). A high-intensity interval training session in trained swimmers significantly increased blood lactate, cortical arousal, and perceived exertion (p<0.05), while decreasing HRV parameters.
