Thirteen male young American football athletes performed three trials of a triple hop test on each leg on two separate occasions. In addition to the total distance hopped, manual detection of touch down and toe-off were calculated via video analysis, enabling flight time (for each hop), ground contact time (GCT), reactive strength index (RSI), and leg stiffness (between hops) to be calculated. Results showed all coefficient of variation (CV) values were \u2264 10.67% and intraclass correlation coefficients (ICC) ranged from moderate to excellent (0.53\u20130.95) in both test sessions. Intrarater reliability showed excellent reliability for all metrics (CV \u2264 3.60%, ICC \u2265 0.97). No systematic bias was evident between test sessions for raw test scores (g = \u22120.34 to 0.32) or the magnitude of asymmetry (g = \u22120.19 to 0.43). However, \u2018real\u2019 changes in asymmetry (i.e., greater than the CV in session 1) were evident on an individual level for all metrics. For the direction of asymmetry, kappa coefficients revealed poor-to-fair levels of agreement between test sessions for all metrics (K = \u22120.10 to 0.39), with the exception of the first hop (K = 0.69). These data show that, given the inherent limitations of distance jumped in the triple hop test, practitioners can confidently gather a range of reliable data when computed manually, provided sufficient test familiarization is conducted. In addition, although the magnitude of asymmetry appears to show only small changes between test sessions, limb dominance does appear to fluctuate between test sessions, highlighting the value of also monitoring the direction of the imbalance.<\/jats:p>","DOI":"10.3390\/sym13101890","type":"journal-article","created":{"date-parts":[[2021,10,11]],"date-time":"2021-10-11T01:59:47Z","timestamp":1633917587000},"page":"1890","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["An Assessment of the Hopping Strategy and Inter-Limb Asymmetry during the Triple Hop Test: A Test\u2013Retest Pilot Study"],"prefix":"10.3390","volume":"13","author":[{"given":"Kyle","family":"Davey","sequence":"first","affiliation":[{"name":"Northwest Rehabilitation Associates, Salem, OR 97302, USA"}]},{"given":"Paul","family":"Read","sequence":"additional","affiliation":[{"name":"Institute for Sport Exercise and Health, Tottenham Court Road, London W1T 7HA, UK"}]},{"given":"Joseph","family":"Coyne","sequence":"additional","affiliation":[{"name":"School of Medical and Health Sciences, Edith Cowan University, Joondalup, WA 6027, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3259-853X","authenticated-orcid":false,"given":"Paul","family":"Jarvis","sequence":"additional","affiliation":[{"name":"Faculty of Science and Technology, London Sport Institute, Middlesex University, London NW4 4BT, UK"}]},{"given":"Anthony","family":"Turner","sequence":"additional","affiliation":[{"name":"Faculty of Science and Technology, London Sport Institute, Middlesex University, London NW4 4BT, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4104-9447","authenticated-orcid":false,"given":"Jon","family":"Brazier","sequence":"additional","affiliation":[{"name":"School of Life and Medical Science, De Havilland Campus, University of Hertfordshire, Hatfield AL10 9EU, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0747-3735","authenticated-orcid":false,"given":"Nejc","family":"\u0160arabon","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, University of Primorska, 6310 Izola, Slovenia"}]},{"given":"Matthew J.","family":"Jordan","sequence":"additional","affiliation":[{"name":"Faculty of Kinesiology, University of Calgary, Calgary, AB T2N 1N4, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1505-1287","authenticated-orcid":false,"given":"Chris","family":"Bishop","sequence":"additional","affiliation":[{"name":"Faculty of Science and Technology, London Sport Institute, Middlesex University, London NW4 4BT, UK"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bishop, C., Abbott, W., Brashill, C., Read, P., Lake, J., and Turner, A.
