However, to date, no study has analyzed the evolution of high-level marathon performances over time. Thus, the purpose of this study was to analyze these performances across the past 42 years with the aim of delineating a time-based classification. To identify the nature of the phenomenon represented by the sequence of observations, we examined the data collected (i.e., 8,400 times from 1969 to 2010) as a time series. The leading time (LT) and the mean 200 times (T200) per year underwent a nonlinear but significant decrement (r = -0.92, p &lt; 0.001 and r = -0.98, p &lt; 0.001, respectively). In fact, from 1969 to 2010, the mean time differences were 3 minutes 20 seconds \u00b1 1 minute 59 seconds and 7 minutes 1 second \u00b1 2 minutes 48 seconds, corresponding to an improvement of 5 and 10 seconds per year for LT and T200, respectively. Furthermore, trend analysis suggested a disruption in marathon time improvements, indicating the presence of 3 points in the time series in which the performance significantly improved with respect to that of the previous years, corresponding to the years 1983-1984 (p &lt; 0.001), 1997-1998 (p &lt; 0.003), and 2003 (p &lt; 0.001). In conclusion, despite the trend in high-level marathon performances being better explained by a nonlinear tendency, significant improvements in the ability of the high-level marathon runners to complete the distance were observed. These improvements are likely to be related to sociological, environmental, physiological, and training-method factors. Researchers and coaches should take into account these enhancements by using the time classification proposed in this study to better reflect the marathon performance profile of their athletes.<\/p>\n<p>J Strength Cond Res. 2011 Dec;25(12):3242-7.\u00a0 \u00a0 \u00a0 <span class=\"id-label\">PMID:\u00a0<\/span><strong class=\"current-id\" title=\"PubMed ID\">22080326\u00a0 \u00a0 \u00a0 \u00a0<\/strong><span class=\"id-label\">DOI: <\/span><a class=\"id-link\" href=\"https:\/\/doi.org\/10.1519\/jsc.0b013e31821bf2bd\" target=\"_blank\" rel=\"noopener\" data-ga-category=\"full_text\" data-ga-action=\"DOI\">10.1519\/JSC.0b013e31821bf2bd<\/a><\/p>\n","protected":false},"featured_media":8155,"template":"","categories":[889,873,890],"tags":[197],"class_list":["post-2687","attivita-scientifica","type-attivita-scientifica","status-publish","has-post-thumbnail","hentry","category-atletica-leggera-en","category-sport-performance-en","category-track-field-en","tag-ermanno-rampinini-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Is it time to consider a new performance classification for high-level male marathon runners?
