Previously, NPN_1 (PeptiStrong\u2122), a Vicia faba hydrolysate derived from a protein concentrate discovered through artificial intelligence (AI), was preclinically shown to help maintain muscle health, indicating the potential to mediate the effect of DOMS and alter molecular markers of muscle damage to improve recovery and performance. A randomised double-blind placebo-controlled trial was conducted on 30 healthy male (30\u201345 years old) volunteers (NCT05159375). Following initial strength testing on day 0, subjects were administered either placebo or NPN_1 (2.4 g\/day). On day 14, DOMS was induced using resistance exercise. Strength recovery and fatigue were measured after 48 and 72 h. Biomarker analysis was performed on blood samples collected prior to DOMS induction and 0, 2, 48 and 72 h post-DOMS induction. NPN_1 supplementation significantly improved strength recovery compared to placebo over the 72 h period post-resistance exercise (p = 0.027), measured by peak torque per bodyweight, but not at individual timepoints. Muscle fatigue was significantly reduced over the same 72 h period (p = 0.041), as was myostatin expression (p = 0.006). A concomitant increase in other acute markers regulating muscle protein synthesis, regeneration and myoblast differentiation was also observed. NPN_1 significantly improves strength recovery and restoration, reduces fatigue and positively modulates alterations in markers related to muscle homeostasis.<\/jats:p>","DOI":"10.3390\/nu15040986","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T02:52:56Z","timestamp":1676515976000},"page":"986","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Improved Strength Recovery and Reduced Fatigue with Suppressed Plasma Myostatin Following Supplementation of a Vicia faba Hydrolysate, in a Healthy Male Population"],"prefix":"10.3390","volume":"15","author":[{"given":"Alish","family":"Kerr","sequence":"first","affiliation":[{"name":"Nuritas Ltd., Joshua Dawson House, D02 RY95 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luke","family":"Hart","sequence":"additional","affiliation":[{"name":"SSC Sports Medicine, Unit C10, Gulliver\u2019s Retail Park, Northwood Avenue, Santry, D09 C523 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heidi","family":"Davis","sequence":"additional","affiliation":[{"name":"Nuritas Ltd., Joshua Dawson House, D02 RY95 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2735-6555","authenticated-orcid":false,"given":"Audrey","family":"Wall","sequence":"additional","affiliation":[{"name":"Nuritas Ltd., Joshua Dawson House, D02 RY95 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Se\u00e1n","family":"Lacey","sequence":"additional","affiliation":[{"name":"Research Integrity & Compliance Officer, Munster Technological University, T12 P928 Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Franklyn-Miller","sequence":"additional","affiliation":[{"name":"SSC Sports Medicine, Unit C10, Gulliver\u2019s Retail Park, Northwood Avenue, Santry, D09 C523 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nora","family":"Khaldi","sequence":"additional","affiliation":[{"name":"Nuritas Ltd., Joshua Dawson House, D02 RY95 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5105-6782","authenticated-orcid":false,"given":"Brian","family":"Keogh","sequence":"additional","affiliation":[{"name":"Nuritas Ltd., Joshua Dawson House, D02 RY95 Dublin, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"652","DOI":"10.1007\/s00421-005-1357-9","article-title":"The effets of exercise-induced muscle damage on maximal intensity intermittent exercise performance","volume":"94","author":"Twist","year":"2005","journal-title":"Eur.
