The  hypotheses predicted extrusion of venous blood by a tonic reflex contraction and  that reactive hyperaemia could be observed after vibration. METHODS: Twelve male  subjects sat in front of a vibration platform with their right foot affixed to  the platform. In four intervals of 3-min duration vibration was applied with a  peak-to-peak displacement of 5 mm at frequencies 15 or 25 Hz, and two foot  positions, respectively. Near infrared spectroscopy was used for measuring  haemoglobin oxygen saturation (SmO2) and the concentration of total haemoglobin  (tHb) in the medial gastrocnemius muscle. RESULTS: Within 30 s of vibration SmO2  increased from 55 +\/- 1 to 66 +\/- 1 % (mean +\/- SE). Within 1.5 min afterwards SmO2  decreased to a steady state (62 +\/- 1 %). During the following 3 min of recovery  SmO2 slowly decreased back to base line. THb decreased within the first 30 s of  vibration, remained almost constant until the end of vibration, and slowly  recovered to baseline afterwards. No significant differences were found for the  two vibration frequencies and the two foot positions. CONCLUSIONS: The relaxed  and unloaded calf muscles did not respond to vibration with a remarkable reflex  contraction. The acceleration by vibration apparently ejected capillary venous  blood from the muscle. Subsequent recovery did not match with a reactive  hyperaemia indicating that the mere mechanical stress did not cause vasodilation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>PURPOSE: During vibration of the whole unloaded lower leg, effects on capillary blood content and blood oxygenation were measured in<\/p>\n","protected":false},"author":22,"parent":0,"menu_order":0,"template":"","format":"standard","meta":{"_acf_changed":false},"tags":[],"thema":[5870,5876,5878,5868,5880,5856,5858],"produktgruppe":[7527,5829],"literatur_kategorie":[7221],"class_list":["post-166716","literatur","type-literatur","status-publish","format-standard","hentry","thema-basics","thema-diseases","thema-medical-applications","thema-over-all-concept","thema-pyhsitherapy-rehabilitation","thema-therapy-prevention-using-galileo","thema-training-with-galileo","produktgruppe-galileo-en","produktgruppe-galileo-training-en","literatur_kategorie-clinical-studies"],"acf":[],"_links":{"self":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/166716","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur"}],"about":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/types\/literatur"}],"author":[{"embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/users\/22"}],"version-history":[{"count":0,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/166716\/revisions"}],"wp:attachment":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/media?parent=166716"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/tags?post=166716"},{"taxonomy":"thema","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/thema?post=166716"},{"taxonomy":"produktgruppe","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/produktgruppe?post=166716"},{"taxonomy":"literatur_kategorie","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur_kategorie?post=166716"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
