Tendon compliance provides a \u2018shock-absorber\u2019 mechanism that rapidly absorbs mechanical energy and releases it more slowly as the recoil of the tendon does work to stretch muscle fascicles. By lowering the rate of muscular energy dissipation, tendon compliance likely reduces the risk of muscle injury that can result from rapid and forceful muscle lengthening. Here, we examine how muscle\u2013tendon mechanics are modulated in response to changes in demand for energy dissipation. We measured lateral gastrocnemius (LG) muscle activity, force and fascicle length, as well as leg joint kinematics and ground-reaction force, as turkeys performed drop-landings from three heights (0.5\u20131.5 m centre-of-mass elevation). Negative work by the LG muscle\u2013tendon unit during landing increased with drop height, mainly owing to greater muscle recruitment and force as drop height increased. Although muscle strain did not increase with landing height, ankle flexion increased owing to increased tendon strain at higher muscle forces. Measurements of the length\u2013tension relationship of the muscle indicated that the muscle reached peak force at shorter and likely safer operating lengths as drop height increased. Our results indicate that tendon compliance is important to the modulation of energy dissipation by active muscle with changes in demand and may provide a mechanism for rapid adjustment of function during deceleration tasks of unpredictable intensity.<\/jats:p>","DOI":"10.1098\/rspb.2014.2800","type":"journal-article","created":{"date-parts":[[2015,2,26]],"date-time":"2015-02-26T11:12:54Z","timestamp":1424949174000},"page":"20142800","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":93,"title":["The series elastic shock absorber: tendon elasticity modulates energy dissipation by muscle during burst deceleration"],"prefix":"10.1098","volume":"282","author":[{"given":"Nicolai","family":"Konow","sequence":"first","affiliation":[{"name":"Department of Ecology and Evolutionary Biology, Brown University, Box G-B204, Providence, RI 02912, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas J.","family":"Roberts","sequence":"additional","affiliation":[{"name":"Department of Ecology and Evolutionary Biology, Brown University, Box G-B204, Providence, RI 02912, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2015,4,7]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.005801"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.038588"},{"key":"e_1_3_4_4_2","first-page":"41","article-title":"The absorption of work when a muscle is stretched","volume":"111","author":"Abbott BC","year":"1950","journal-title":"J.
