|Title:||Metabolic power and energetic costs of elite Rugby League match-play||Contributor(s):||Cummins, Cloe (author) ; Gray, Adrian (author) ; Shorter, Kathleen (author) ; Halaki, Mark (author); Orr, Rhonda (author)||Publication Date:||2015||Handle Link:||https://hdl.handle.net/1959.11/21066||Abstract:||Background: Mechanical time-motion models based on running velocity have estimated the energy demands of field-based team sports. Such analyses have enhanced the understanding of the metabolic loads of match-play and aided in player preparation. The purpose of this study therefore is to describe the metabolic demands of different playing positions in elite rugby league match-play. Methods: A running based time-motion model was utilised to estimate the energy expenditure and metabolic demands of 18 elite rugby league players using 15Hz Global Positioning System (GPS) units. Briefly, this model uses a player's GPS velocity-time curve to estimate the positive/ negative mechanical work done by the centre of mass in the horizontal/vertical planes, by the swinging-limbs and to overcome air-resistance. It is assumed that the sum of these components is the total mechanical-work done due to locomotor demands. Players were categorized into positional groups: outside backs (OB), adjustables (ADJ), wide-running forwards (WRF) and hit-up forwards (HUF). Game demands were quantified by match time (min), relative distance (m.min⁻¹), energy expenditure (kJ.kg⁻¹), mean power (W.kg⁻¹), anaerobic index (arbitrary-unit) and equivalent distance (m).||Publication Type:||Conference Publication||Conference Name:||2015 ASICS Sports Medicine Australia Conference, Gold Coast, Australia, 21st - 24th October, 2015||Conference Details:||2015 ASICS Sports Medicine Australia Conference, Gold Coast, Australia, 21st - 24th October, 2015||Source of Publication:||2015 ASICS Sports Medicine Australia Conference Book of Abstracts, p. 24-24||Publisher:||Sports Medicine Australia||Place of Publication:||Australia||ISSN:||1440-2440||Field of Research (FOR):||110699 Human Movement and Sports Science not elsewhere classified||Socio-Economic Outcome Codes:||950102 Organised Sports||HERDC Category Description:||E3 Extract of Scholarly Conference Publication||Other Links:||http://sma.org.au/wp-content/uploads/2015/10/BOA-Final-lr.pdf||Series Name:||Journal of Science and Medicine in Sport||Series Number :||December 2015 Supplement||Statistics to Oct 2018:||Visitors: 16
