Franck Di Rienzo et al., « Physiological changes in response to apnea impact the timing of motor representations: a preliminary study », HAL-SHS : sciences de l'éducation, ID : 10670/1.0yzz5k
Background: Reduced physiological arousal in response to breath-holding affects internal clock processes, leading swimmers to underestimate the time spent under apnea. We investigated whether reduced physiological arousal during static apnea was likely to affect the temporal organization of motor imagery (MI). Methods: Fourteen interregional to national breath-holding athletes mentally and physically performed two 15 m swimming tasks of identical durations. They performed the two sequences in a counterbalanced order, the first while breathing normally using a scuba, the second under apnea. We assessed MI duration immediately after completion of the corresponding task. Athletes performed MI with and without holding breath.
