Early studies have proposed beneficial effects upon range of motion (ROM), however the mechanism behind these increases remains unreported. This study aimed to determine the influence of a minimal frequency PT dose upon ROM and myotonometry outcomes. Twenty participants (N = 20; 13 males and 7 females, height 1.78cm \u00b1 9.62; weight 77.35kg \u00b1 8.46) participants were allocated to either a PT group receiving 2 x 60-seconds (plus 30-seconds rest) via a Theragun\u2122 Pro4 to the hamstrings covering a standardised 20 lengths from proximal to distal via the standard ball attachment at 1 bar of pressure or a control group (CON) of 2-minutes 30-seconds passive supine rest. Pre and post intervention outcomes were measured for ROM via passive straight leg raise (PSLR) and tissue dynamics via MyotonPro (Tone, Stiffness, Elasticity, Relaxation Time). Results showed significant within-group increases (p &lt; 0.0001, \u03b7p2 0.656, +11.4%) in ROM following PT and between group difference against CON (P &lt; 0.026). Significant within-group differences in stiffness (p &lt; 0.016, \u03b7p2 0.144, -6%), tone (p &lt; 0.003, \u03b7p2 0.213, +2%) and relaxation time (p &lt; 0.002, \u03b7p2 0.232, +6.3%) were also reported following PT. No significant difference was reported in elasticity (P &gt; 0.05) or any other between group outcomes. PT therapy can provide an acute increase in hamstring group ROM following a resultant decrease in tissue stiffness.<\/jats:p>","DOI":"10.52082\/jssm.2023.496","type":"journal-article","created":{"date-parts":[[2023,9,7]],"date-time":"2023-09-07T06:46:06Z","timestamp":1694069166000},"page":"496-501","source":"Crossref","is-referenced-by-count":30,"title":["The Acute Effects of Theragun\u2122 Percussive Therapy on Viscoelastic Tissue Dynamics and Hamstring Group Range of Motion"],"prefix":"10.52082","author":[{"given":"Brendon","family":"Skinner","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren","family":"Dunn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Moss","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"29163","published-online":{"date-parts":[[2023,9,1]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Agyapong B.S., Warner M., Samuel D., Stokes M.
