While walking and running biomechanics are well studied, joint\u2010specific kinetic data during a single leg drop and hop task, often used in rehabilitation, are lacking. This study aimed to evaluate (1) the kinetic behavior of the ankle, Chopart, Lisfranc, and MTP\u20101 joints during a drop\u2010hop task under different visual constraints and (2) to contextualize these findings by comparing them with heel\u2010strike running, to assess the relative loading demands of the drop\u2010hop task.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Seventeen recreationally active male adults performed a single\u2010leg drop and hop under two visual focus conditions: central (focusing on the landing spot) and peripheral (focusing straight ahead). Kinematics, moments, and power were analyzed using a four\u2010segment foot model with statistical parametric mapping. Additionally, peak plantarflexion moments and power outputs were compared with existing data from heel\u2010strike running data from a mixed\u2010sex sample (4 males, 3 females) collected in a separate study using the same setup.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Findings revealed no differences between central and peripheral focus conditions. Heel\u2010strike running shows similar joint loading, but higher power generation (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) at the ankle and Chopart joint, higher absorption (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) at the Chopart and MTP\u20101 (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05) joint and lower power absorption (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) at the ankle and Lisfranc joint.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Visual input does not influence foot biomechanics during a single\u2010leg drop and hop. This task produces similar joint loading patterns similar to heel\u2010strike running but with reduced power generation at the ankle and midfoot. Contrary to global belief, the single leg drop\u2010hop task is not excessively more demanding in terms of foot joint loading, supporting the earlier use of drop\u2010hop exercises in rehabilitation programs. They offer a controlled way to reintroduce loading while avoiding the full propulsion demands of running, independent of visual focus.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jfa2.70078","type":"journal-article","created":{"date-parts":[[2025,9,2]],"date-time":"2025-09-02T04:40:12Z","timestamp":1756788012000},"source":"Crossref","is-referenced-by-count":0,"title":["Single Leg Drop and Hop: Insight Into Multisegment Foot Kinematics, Kinetics and the Role of Visual Focus in Healthy Young Adult Males"],"prefix":"10.1002","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7510-7844","authenticated-orcid":false,"given":"Nicolas","family":"Haelewijn","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Sciences Musculoskeletal Rehabilitation Research Group KU Leuven  Brugge Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1569-6333","authenticated-orcid":false,"given":"Filip","family":"Staes","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences Musculoskeletal Rehabilitation Research Group KU Leuven  Leuven Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1312-9124","authenticated-orcid":false,"given":"Evie","family":"Vereecke","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences Musculoskeletal Rehabilitation Research Group KU Leuven  Leuven Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stijn","family":"Rosseel","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences Musculoskeletal Rehabilitation Research Group KU Leuven  Brugge Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6559-6237","authenticated-orcid":false,"given":"Kevin","family":"Deschamps","sequence":"additional","affiliation":[{"name":"Department of Development &amp; Regeneration Campus Kulak KU Leuven  Kortrijk Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.4103\/ortho.IJOrtho_226_17"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/jsm.0b013e3181f3c0fe"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12178\u2010017\u20109426\u20103"},{"key":"e_1_2_11_5_1","article-title":"Criteria\u2010Based Rehabilitation and Return to Sport Testing After Anterior Cruciate Ligament Reconstruction","volume":"12","author":"Roula Kotsifaki R.
