Recent studies have indicated that breathing phases, particularly exhalation, synchronize with voluntary actions, potentially reflecting a general influence on motor intention. However, this effect might depend on the specific effector and movement direction. This study aimed to investigate (i) respiratory synchronization across different voluntary motor tasks, (ii) the interaction between stimulus\u2010locked and action\u2010locked respiratory coupling, and (iii) cardiac synchronization with voluntary actions. A total of 32 healthy participants performed two voluntary motor tasks: a modified Libet clock task and an elbow flexion\u2013extension task. In the Libet clock task, the participants monitored a rotating dot on a clock face and either pressed a key at a self\u2010chosen time (key\u2010press condition) or released the key after holding it pressed (key\u2010release condition). In the elbow flexion\u2013extension task, the participants spontaneously pushed (elbow extension) or pulled (elbow flexion) a joystick. Across tasks, voluntary actions showed an overall tendency to occur during exhalation across multiple effectors (finger and elbow) and movement directions (extension and flexion). Furthermore, stimulus\u2010locked respiratory phase was associated with subsequent action timing, suggesting that trial structure can shape respiration\u2013action coupling. We found no robust evidence for systematic cardiac\u2010phase modulation of voluntary action timing, although a weak condition\u2010specific trend was observed. Collectively, these findings support respiration\u2013action coupling across diverse actions and highlight a potential contribution of stimulus\u2010locked respiratory dynamics to voluntary action timing.<\/jats:p>","DOI":"10.1111\/psyp.70264","type":"journal-article","created":{"date-parts":[[2026,2,18]],"date-time":"2026-02-18T11:04:21Z","timestamp":1771412661000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Respiratory and Cardiac Phase Coupling With Voluntary Actions Across Motor Tasks"],"prefix":"10.1111","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4507-5092","authenticated-orcid":false,"given":"Hiroshi","family":"Shibata","sequence":"first","affiliation":[{"name":"Department of Informatics Nagoya University  Nagoya Aichi Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideki","family":"Ohira","sequence":"additional","affiliation":[{"name":"Department of Informatics Nagoya University  Nagoya Aichi Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,18]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/biomet\/55.2.343"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms13854"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1977.sp012059"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v031.i10"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2023.105262"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tins.2020.10.007"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.copsyc.2017.04.020"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cobeha.2017.08.014"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41583\u2010018\u20100003\u20106"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhn230"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.2466\/pms.2002.95.2.339"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pbio.3003478"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.3507\u201013.2014"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1038\/s42003\u2010024\u201006642\u20103"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1436\u201015.2015"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0592\u201021.2021"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.3245\u201015.2016"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2024.2566"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1519\/JSC.0b013e31818eb256"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010022\u201006364\u20108"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.106.180200"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.7554\/eLife.70907"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010023\u201040250\u20109"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00412364"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00421\u2010015\u20103250\u20105"},{"key":"e_1_2_10_27_1","doi-asserted-by":"publisher","DOI":"10.1111\/psyp.13322"},{"key":"e_1_2_10_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20592"},{"key":"e_1_2_10_29_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/106.3.623"},{"key":"e_1_2_10_30_1","first-page":"244","volume-title":"Handbook of Psychophysiology","author":"Lorig T.
