Furthermore, no information is available on the effect of the individual levels of lower limbs&#8217; explosive strength on yo-yo tests in soccer players. The purpose of this study was to examine the physiological determinants of Yo-yo Endurance Test Level 2 (YYETL2) and Yo-yo Intermittent Recovery Test Level 1 (YYIRTL1) in soccer players. Twenty-four soccer players (body mass, 74.6 +\/- 8.5 kg; height, 178.1 +\/- 4.5 cm; age, 25.6 +\/- 5.1 years) were tested for VO<sub>2<\/sub>max and ventilatory threshold (VT) on a motorized treadmill. Lower-limb explosive strength was assessed using vertical countermovement jumps (CMJ) performed on a force platform. Results showed that YYETL2 and YYIRTL1 performances (m) were significantly related (r = 0.75, p = 0.00002). YYETL2 results were significantly related to VO<sub>2<\/sub>max, VTVO<sub>2<\/sub>, and speed at VT (r = 0.75, 0.76, and 0.83, respectively; p &lt; 0.00002). Peak treadmill speed results were significantly related to YYETL2 and YYIRTL1 (r = 0.87 and 0.71, respectively; p &lt; 0.0003). YYIRTL1 was related to CMJ peak power (r = 0.57; p = 0.003). These findings show that YYETL2 and YYIRTL1, although adopting similar starting and progression speeds, are influenced by different physiological variables. From these results, YYETL2 can be considered an aerobic fitness-related field test, whereas YYIRTL1 can be regarded as an aerobic-anaerobic, soccer-specific field test.<\/p>\n<p>J Strength Cond Res. 2006 May;20(2):320-5.<\/p>\n","protected":false},"featured_media":8155,"template":"","categories":[858,863,859],"tags":[447,908,653],"class_list":["post-2724","attivita-scientifica","type-attivita-scientifica","status-publish","has-post-thumbnail","hentry","category-calcio-en","category-soccer-3-en","category-testing-en","tag-domenico-carlomagno-en","tag-franco-impellizzeri-en","tag-rampinini-ermanno-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
