The purpose of this study was to examine the relationship between heart rate (%HR<sub>peak<\/sub>) and blood lactate ([BLa<sup>&#8211;<\/sup>]) measures of exercise intensity with each player&#8217;s RPE during soccer-specific aerobic exercises. Mean individual %HR(peak), ([BLa<sup>&#8211;<\/sup>]) and RPE (Borg&#8217;s CR 10-scale) were recorded from 20 amateur soccer players from 67 soccer-specific small-sided games training sessions over an entire competitive season. The small-sided games were performed in three 4min bouts separated with 3min recovery on various sized pitches and involved 3-, 4-, 5-, or 6-players on each side. A stepwise linear multiple regression was used to determine a predictive equation to estimate global RPE for small-sided games from [BLa<sup>&#8211;<\/sup>] and %HR<sub>peak<\/sub>. Partial correlation coefficients were also calculated to assess the relationship between RPE, [BLa<sup>&#8211;<\/sup>] and %HR<sub>peak<\/sub>. Stepwise multiple regression analysis revealed that 43.1% of the adjusted variance in RPE could be explained by HR alone. The addition of [BLa<sup>&#8211;<\/sup>] data to the prediction equation allowed for 57.8% of the adjusted variance in RPE to be predicted (Y=-9.49-0.152 %HR<sub>peak<\/sub>+1.82 [BLa<sup>&#8211;<\/sup>], p&lt;0.001). These results show that the combination of [BLa<sup>&#8211;<\/sup>] and %HR<sub>peak<\/sub> measures during small-sided games is better related to RPE than either %HR<sub>peak<\/sub> or [BLa<sup>&#8211;<\/sup>] measures alone. These results provide further support the use of RPE as a measure of global exercise intensity in soccer.<\/p>\n<p>J Sci Med Sport. 2009 Jan;12(1):79-84.<\/p>\n<p><span class=\"id-label\">PMID:\u00a0<\/span><strong class=\"current-id\" title=\"PubMed ID\">18068433\u00a0 \u00a0 \u00a0<\/strong><span class=\"id-label\">DOI: <\/span><a class=\"id-link\" href=\"https:\/\/doi.org\/10.1016\/j.jsams.2007.08.005\" target=\"_blank\" rel=\"noopener\" data-ga-category=\"full_text\" data-ga-action=\"DOI\">10.1016\/j.jsams.2007.08.005<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"featured_media":18274,"template":"","categories":[858,862,863],"tags":[197,908],"class_list":["post-2698","attivita-scientifica","type-attivita-scientifica","status-publish","has-post-thumbnail","hentry","category-calcio-en","category-monitoring-en","category-soccer-3-en","tag-ermanno-rampinini-en","tag-franco-impellizzeri-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
