Experiencing vasovagal symptoms has been found to reduce blood donor return. However, does practicing applied tension improve blood donor return? Follow\u2010up results from a randomized controlled trial are presented.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data were collected in mobile clinics held in several colleges and universities. During the baseline donation, participants either (1) practiced \u2018standard\u2019 applied tension consisting of repeated 5\u00a0s cycles of whole\u2010body isometric muscle tension in the donation chair (<jats:italic>N\u00a0<\/jats:italic>=\u00a0133), (2) practiced tension with legs crossed (<jats:italic>N\u00a0<\/jats:italic>=\u00a0131), or (3) gave blood as usual (<jats:italic>N\u00a0<\/jats:italic>=\u00a0140).
