In the present study, we assessed changes on SS soon after a maximal dynamic apnoea.\nMethods: Thirty-nine experienced male breath-hold divers were recruited. Critical flicker fusion frequency (CFFF) thresholds were used to measure SS. Thresholds were determined before and after a maximal dynamic apnoea. Immediately after surfacing, heart rate and oxygen saturation (SpO2) were recorded for two minutes.\nResults: After maximal dynamic apnoea, SpO2 was significantly decreased (from mean 97.3% pre-dive to mean 63.1% post-dive; P &amp;#x0003C; 0.0001; \u03b72 P = 0.86), but this acute hypoxaemia did not trigger changes in SS (post-dive value 102% of baseline; P = 0.22; \u03b72 P = 0.03). Pearson correlation analysis revealed a moderate association between SS with swimming speed \n(r = 0.423) and apnoea time (r = -0.404).\nConclusions: A maximal dynamic apnoea did not produce changes in central nervous system fatigue or cortical arousal. We found no relationship between the hypoxaemia level reached after a maximal apnoea and changes in the CFFF thresholds. This study suggests that the time of exposure to hypoxia during a maximal voluntary apnoea is not enough to produce changes in SS.<\/jats:p>","DOI":"10.28920\/dhm49.3.186-191","type":"journal-article","created":{"date-parts":[[2019,9,9]],"date-time":"2019-09-09T21:59:07Z","timestamp":1568066347000},"page":"186-191","source":"Crossref","is-referenced-by-count":10,"title":["Assessment of sensory sensitivity through critical flicker fusion frequency thresholds after a maximum voluntary apnoea"],"prefix":"10.28920","volume":"49","author":[{"name":"Departament of Health, Centro Superior de Estudios Universitarios La Salle.
