Strat-egies that maximize nerve regeneration and functional recovery are necessary, the exercise is an option. This study evaluated the effects of forced swimming exercise on neuromuscular histomorphometry and on functional recovery in a median nerve crush model. Sixteen Wistar rats underwent median nerve crush and were divided into control group (CG) and swimming group (SG). The forced swimming protocol started one week after the injury and was performed for 1 hr a day, 5 days per week, for 2 weeks. The rats swam with an overload of 5% and 10% of body weight in the first and second week, respectively. The functional recovery was assessed in three moments using the grasping test. On day 21, fragments of the median nerve and of the forearm flexors mus-cles were removed for histomorphometric analysis. The SG had func-tional recovery impaired (&lt;i&gt;p&lt;\/i&gt;&lt;0.001) and presented lower myelinated fi-bers number, fiber and axon minimal diameter, myelin thickness and g-ratio in the proximal e distal segments of the median nerve (&lt;i&gt;p&lt;\/i&gt;&lt;0.005) and area muscle fiber (&lt;i&gt;p&lt;\/i&gt;&lt;0.005) than CG. Also, the SG presented a number of capillaries in the proximal segments of the median nerve greater than CG (&lt;i&gt;p&lt;\/i&gt;&lt;0.005). The exercise protocol used in this study im-paired the regeneration of the median nerve and negatively influenced the functional recovery.<\/jats:p>","DOI":"10.12965\/jer.2244150.075","type":"journal-article","created":{"date-parts":[[2022,6,27]],"date-time":"2022-06-27T05:38:18Z","timestamp":1656308298000},"page":"179-186","update-policy":"https:\/\/doi.org\/10.12965\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Negative
