Force plates and qualitative screening tools are feasible and effective screening methods to identify abnormal movement quality associated with increased injury risk. Comparing qualitative assessments of landing ability with force\u2010time curves, may detect unique differences between safe and high\u2010risk athletic movement patterns. The aim of this study was to determine low\u2010 and high\u2010risk landing ability from qualitive landing assessments and to examine the resulting force\u2010time curves using functional principal component analysis (fPCA). Thirty\u2010one healthy academy athletes (10 males and 21 females) completed double\u2010 and single\u2010leg dominant and non\u2010dominant jump\u2010landing\u2010rebound tasks. All movements were filmed in multiple\u2010planes, and vertical ground reaction forces (vGRF) were simultaneously collected. The Landing Error Scoring System (LESS) and Single\u2010Leg Landing Error Scoring System (SL\u2010LESS) were used to score landing footage. From these scores, athletes were categorized into low\u2010risk and high\u2010risk groups for further analysis. fPCA was used to examine differences between landing quality groups force\u2010time curves. Compared to high\u2010risk landers, low\u2010risk landers demonstrated significantly longer contact times across all movements. Scores from fPC1 revealed safe and high\u2010risk landing techniques expose athletes to significantly different loading patterns during double\u2010 and single\u2010leg dominant movements. A significant positive relationship was observed between fPC1 and LESS scores, however this relationship was not observed in both single\u2010leg landing scores. Where possible incorporating curve analysis methods like fPCA into multi\u2010faceted screening approaches may help practitioners uncover unique insights into athletic loading strategies.<\/jats:p>","DOI":"10.1111\/sms.14272","type":"journal-article","created":{"date-parts":[[2022,11,21]],"date-time":"2022-11-21T10:47:38Z","timestamp":1669027658000},"page":"420-432","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Curves
