Participants were median split into faster and slower COD speed groups, and these were compared by independent t-tests. The faster group was significantly better (p ≤ 0.05) on the sprint acceleration and reactive strength tests (large effect size). The correlations between physical qualities and agility were trivial to small (r = -0.101 to 0.123, p > 0.05) and collectively explained only 14.2% of the variance associated with agility performance (adjusted R2 = -0.142, p > 0.05). When faster and slower agility groups were compared, there were trivial to moderate differences (p > 0.05) in all physical qualities. It was concluded that reactive strength and sprint acceleration are important for COD speed, but the physical qualities assessed are not associated with defensive agility performance. For agility tasks similar to those in this study, sprint and resistance training should not be emphasized, and training other factors, such as the development of sportspecific technique and cognitive skill, is recommended. © 2015 National Strength and Conditioning Association.]]> Wed 07 Apr 2021 13:53:20 AEST ]]> Association between leg power and sprinting technique with 20-m sprint performance in elite junior australian football players http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:7570 0.05). A multiple regression indicated that the two-bound test and technique accounted for 37.7% of the variance associated with the 20-m sprint time (p<0.05). It was concluded that the technique assessment tool captured some important characteristics of 20-m sprint performance and could potentially be used to profile or monitor athletes. Further the two-bound test is a more relevant test for developing athletes because of its specificity to sprinting, compared to the CMJ.]]> Wed 07 Apr 2021 13:47:02 AEST ]]> The acute effects of conventional, complex, and contrast protocols on lower-body power http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:5889 Wed 07 Apr 2021 13:45:28 AEST ]]> The effect of including a series of isometric conditioning contractions to the rowing warm-up on 1,000-m rowing ergometer time trial performance http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:4843 0.05). The PW improved mean power output by 6.6% (p < 0.01) and mean stroke rate by 5.2% (p < 0.01) over the first 500 m; resulting in a reduction of 500-m time by 1.9% (p < 0.01), compared with the NW. It appears that the inclusion of isometric conditioning contractions to the rowing warm-up enhance short-term rowing ergometer performance (especially at the start of a race) to a greater extent than a rowing warm-up alone. © 2012 National Strength and Conditioning Association.]]> Wed 07 Apr 2021 13:44:23 AEST ]]> Countermovement jump variables not tensiomyography can distinguish between sprint and endurance focused track cyclists http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:16782 Tue 25 Oct 2022 13:57:46 AEDT ]]> Development of muscle mass : How much is optimum for performance? http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:14195 Tue 21 Dec 2021 09:29:48 AEDT ]]> Does the warm-up effect subsequent post activation performance enhancement? http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:17236 Tue 07 Mar 2023 15:48:23 AEDT ]]> The occurrence of different vertical jump types in basketball competition and their relationship with lower-body speed-strength qualities http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:17249 Mon 13 Feb 2023 10:53:07 AEDT ]]> Sprinting and hamstring strain injury : beliefs and practices of professional physical performance coaches in Australian football http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:15105 Mon 09 May 2022 16:48:59 AEST ]]>
