Subjects, assigned to either weight stack (grp WS; n = 8) or iso-inertial \u201ceccentric overload\u201d Xywheel (grp FW; n = 9) knee extensor resistance training, completed 12 sessions of four sets of seven concentric\u2013eccentric actions. Pre- and post-measurements comprised maximal voluntary contrac- tion (MVC), rate of force development (RFD) and training mode-speciWc force. Root mean square electromyographic (EMGRMS) activity of mm. vastus lateralis and medialis was assessed during MVC and used to normalize EMGRMS for training mode-speciWc concentric (EMGCON) and eccentric (EMGECC) actions at 90\u00b0, 120\u00b0 and 150\u00b0 knee joint angles. Grp FW showed greater (p &lt; 0.05) overall normalized angle-speciWc EMGECC of vastii muscles compared with grp WS. Grp FW showed near maximal normalized EMGCON both pre- and post-training. EMGCON for Grp WS was near maximal only post-training. While RFD was unchanged following training (p &gt; 0.05), MVC and training-specific strength increased (p &lt; 0.05) in both groups.We believe the higher EMGECC activity noted with FW exercise compared to standard weight lifting could be attributed to its unique iso-inertial loading features. Hence, the resulting greater mechanical stress may explain the robust muscle hypertrophy reported earlier in response to Xywheel resistance training.<\/p>\n<p>Keywords Concentric and eccentric actions \u00b7 Electromyography \u00b7 Iso-inertia \u00b7 Resistance exercise<\/p>\n<div  class='avia-button-wrap avia-button-left  avia-builder-el-0  avia-builder-el-no-sibling ' ><a href='https:\/\/einercial.com\/wp-content\/uploads\/2019\/02\/2010_Norrbrandetalpdf.pdf' class='avia-button  avia-color-theme-color   avia-icon_select-no avia-size-large avia-position-left ' target=\"_blank\" rel=\"noopener noreferrer\"><span class='avia_iconbox_title' >Seguir leyendo en PDF<\/span><\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Abstract Changes in muscle activation and performance were studied in healthy men in response to 5 weeks of resistance training with or without \u201ceccentric overload\u201d.
