Foot strike pattern has been shown to influence VLR while running, but little is known about its influence on PFA. Twenty healthy women ran on a treadmill for 2 conditions: with a rearfoot strike and with a forefoot strike. PFA was measured with electromyography. Running kinematics associated with VLR were collected using inertial measurement units and tibial accelerometers. Change scores between conditions were calculated for average PFA and running kinematics: peak vertical tibial acceleration, vertical excursion of the center of mass (VO), and cadence. Paired <jats:italic>t<\/jats:italic> tests assessed differences between running conditions for all variables. Pearson correlations assessed the relationships between changes in PFA and running kinematics. PFA was significantly higher during the forefoot compared with the rearfoot strike condition. Change in vertical tibial acceleration was positively correlated with change in PFA during the right stance. Change in cadence was negatively correlated, and change in vertical excursion of the center of mass was positively correlated with change in PFA during left stance. The average PFA increased during the forefoot strike pattern condition. Changes in PFA were correlated with changes in running kinematics associated with VLR.<\/jats:p>","DOI":"10.1123\/jab.2024-0078","type":"journal-article","created":{"date-parts":[[2024,9,6]],"date-time":"2024-09-06T21:22:30Z","timestamp":1725657750000},"page":"416-423","source":"Crossref","is-referenced-by-count":2,"title":["The Effects of Running Foot Strike Manipulation on Pelvic Floor Muscle Activity in Healthy Nulliparous Females"],"prefix":"10.1123","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5421-1215","authenticated-orcid":true,"given":"Michael","family":"Steimling","sequence":"first","affiliation":[{"name":"School of Rehabilitation Sciences, Moravian University, Bethlehem, PA, USA"},{"name":"St Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melinda","family":"Steimling","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Sciences, Moravian University, Bethlehem, PA, USA"},{"name":"St Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2543-3198","authenticated-orcid":true,"given":"Philip","family":"Malloy","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Arcadia University, Glenside, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0821-1078","authenticated-orcid":true,"given":"Kathleen","family":"Madara","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Sciences, Moravian University, Bethlehem, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"6","key":"r1","series-title":"J Urol","doi-asserted-by":"publisher","first-page":"2286","DOI":"10.1016\/j.juro.2008.01.098","article-title":"Stress urinary incontinence: relative importance of urethral support and urethral closure pressure","volume":"179","author":"DeLancey JOL","year":"2008","unstructured":"DeLancey JOL, Trowbridge ER, Miller JM, et\u00a0al.
