Title: | Importance, Reliability, and Usefulness of Acceleration Measures in Team Sports | Contributor(s): | Delaney, Jace A (author); Cummins, Cloe j (author) ; Thornton, Heidi R (author); Duthie, Grant M (author) | Publication Date: | 2018-12 | DOI: | 10.1519/jsc.0000000000001849 | Handle Link: | https://hdl.handle.net/1959.11/26484 | Abstract: | The ability to accelerate, decelerate, and change direction efficiently is imperative to successful team sports performance. Traditional intensity-based thresholds for acceleration and deceleration may be inappropriate for time-series data and have been shown to exhibit poor reliability, suggesting other techniques may be preferable. This study assessed movement data from one professional rugby league team throughout 2 full seasons and 1 preseason period. Using both 5 and 10 Hz global positioning systems (GPS) units, a range of acceleration-based variables were evaluated for their interunit reliability, ability to discriminate between positions, and associations with perceived muscle soreness. The reliability of 5 Hz global positioning systems for measuring acceleration and deceleration ranged from good to poor (CV = 3.7–27.1%), with the exception of high-intensity deceleration efforts (CV = 11.1–11.8%), the 10 Hz units exhibited moderate-to-good interunit reliability (CV = 1.2–6.9%). Reliability of average metrics (average acceleration/deceleration, average acceleration, and average deceleration) ranged from good to moderate (CV = 1.2–6.5%). Substantial differences were detected between positions using time spent accelerating and decelerating for all magnitudes, but these differences were less clear when considering the count or distance above acceleration/deceleration thresholds. All average metrics detected substantial differences between positions. All measures were similarly related to perceived muscle soreness, with the exception of high-intensity acceleration and deceleration counts. This study has proposed that averaging the acceleration/deceleration demands over an activity may be a more appropriate method compared with threshold-based methods, because a greater reliability between units, while not sacrificing sensitivity to within-subject and between-subject changes. | Publication Type: | Journal Article | Source of Publication: | Journal of Strength and Conditioning Research, 32(12), p. 3485-3493 | Publisher: | Lippincott Williams & Wilkins | Place of Publication: | United States of America | ISSN: | 1533-4287 1064-8011 |
