Among supplements often consumed to support musculotendinous health, collagen hydrolysate (CH) has gained popularity for its potential in improving joint comfort and function. This single-blind quasi-experimental study investigated the effects of a three-month oral supplementation with a specific CH-based product, Chondrovita FIT\u00ae (Bone Srl, Rome, Italy), on tendon structure in elite Italian skaters. Eighteen male and female elite skaters (mean age: 21 \u00b1 3 years) participated, receiving daily pre-workout (4500 mg CH) and post-workout (2500 mg CH) doses. Tendon structure in the patellar and peroneal tendons was assessed using ultrasound imaging at baseline and post-supplementation. Results showed a significant increase in tendon thickness in both the patellar and peroneal tendons after supplementation, although no changes were observed in the tendon cross-sectional area. These findings suggest that Chondrovita FIT\u00ae supplementation may induce beneficial structural changes in tendons, potentially supporting tendon health and performance in high-load sports. However, further research is needed to confirm long-term effects and functional outcomes.<\/jats:p>","DOI":"10.3390\/ijerph22010024","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T07:51:57Z","timestamp":1735631517000},"page":"24","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Changes in Tendon Thickness After Chondrovita FIT\u00ae Supplementation in Elite Skaters: Findings from a Quasi-Experimental Study"],"prefix":"10.3390","volume":"22","author":[{"given":"Silvana","family":"Giannini","sequence":"first","affiliation":[{"name":"Villa Stuart Sport Clinic-FIFA Medical Centre of Excellence, 00136 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7497-755X","authenticated-orcid":false,"given":"Stefano","family":"Amatori","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Section of Exercise and Health Sciences, University of Urbino Carlo Bo, 61029 Urbino, Italy"},{"name":"Department of Theoretical and Applied Sciences, eCampus University, Novedrate, 22060 Como, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Vetrano","sequence":"additional","affiliation":[{"name":"Physical Medicine and Rehabilitation Unit, Sant\u2019Andrea Hospital, \u201cSapienza\u201d University of Rome, 00189 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4028-0652","authenticated-orcid":false,"given":"Michela","family":"Battistelli","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Section of Exercise and Health Sciences, University of Urbino Carlo Bo, 61029 Urbino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8561-6088","authenticated-orcid":false,"given":"Annalisa","family":"Belli","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Service of Biostatistics, University of Urbino Carlo Bo, Piazza Rinascimento 7, 61029 Urbino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giorgia Simona","family":"Musicco","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Section of Exercise and Health Sciences, University of Urbino Carlo Bo, 61029 Urbino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0056-5795","authenticated-orcid":false,"given":"Marco Bruno Luigi","family":"Rocchi","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Service of Biostatistics, University of Urbino Carlo Bo, Piazza Rinascimento 7, 61029 Urbino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7925-7495","authenticated-orcid":false,"given":"Davide","family":"Sisti","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Service of Biostatistics, University of Urbino Carlo Bo, Piazza Rinascimento 7, 61029 Urbino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2094-4351","authenticated-orcid":false,"given":"Fabrizio","family":"Perroni","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Sciences, Section of Exercise and Health Sciences, University of Urbino Carlo Bo, 61029 Urbino, Italy"},{"name":"\u201cMuseum of Football F.I.G.C.\u201d Foundation, Italian Football Federation, Via Gregorio Allegri 14, 00198 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Amatori, S., Sisti, D., Perroni, F., Impey, S., Lantignotti, M., Gervasi, M., Donati Zeppa, S., and Rocchi, M.B.L.
