Results: The mean (+/- SD) TD covered by field umpires was 11,492 +/- 1,729 m, with boundary umpires covering 15,061 +/- 1,749 m. The average running speed in field umpires was 103 +/- 14 m.min(-1) and was 134 +/- 14 m.min(-1) in boundary umpires. Field and boundary umpires covered 3,095 +/- 752 m and 5,875 +/- 1,590 m, during HIA, respectively. In the first quarter, HIA distance (field: P = .004, eta(2) = 0.071, boundary: P < .001, eta(2) = 0.180) and average running speed (field: P = .002, eta(2) = 0.078, boundary: P < .001, eta(2) = 0.191) were significantly greater than in subsequent quarters. Conclusions: The results demonstrate that both AF field and boundary umpires complete similar running demands to elite AF players and are subject to physical fatigue. Further research is warranted to see if this physical fatigue impacts on the cognitive function of AF umpires during match play.]]> Wed 11 Apr 2018 12:16:04 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39067 14.0 km·h-1; >14.1 km·h-1; >14.4 km·h-1) and very high-speed activity (VHSA) (>19.1 km·h-1; >19.8 km·h-1; >21.0 km·h-1) were reported. Average total distance (TD) ranged from 10,274 m (Australia) to 11,389 m (Italy). Comparison between positions showed that centre-backs generally covered the least distance (TD = 10,178 m; HSA = 1,886 m-1,940 m; VHSA = 391 m-621 m) and wide-midfielders the greatest distance (TD = 11,654 m; HSA = 3,006 m-3,406 m; VHSA = 753 m-1,216 m). This review of timemotion analysis demonstrated fairly similar outcomes for most domestic top-level leagues but suggests a strong influence of contextual variables. The consistently reported positional differences likely reflect the varied tactical demands of each position. The review proposes reaching a consensus on velocity threshold definitions and integrating contextual information in future research.]]> Wed 04 May 2022 14:14:33 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53303 Tue 21 Nov 2023 12:03:01 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18154 -1·min^-1) completed repeat progressive maximal tests (PMT) and time-to-exhaustion (TTE) tests at 90% VO₂max wearing either manufacturer-recommended LBCG (rLBCG), undersized LBCG (uLBCG), or loose running shorts (CONT). During all exercise testing, several systemic and peripheral physiological measures were taken. Results: The results indicated similar effects of wearing rLBCG and uLBCG compared with the control. Across the PMT, wearing either LBCG resulted in significantly (P < .05) increased oxygen consumption, O₂pulse, and deoxyhemoglobin (HHb) and decreased running economy, oxyhemoglobin, and tissue oxygenation index (TOI) at low-intensity speeds (8–10 km·h^-1). At higher speeds (12–18 km·h^-1), wearing LBCG increased regional blood flow (nTHI) and HHb values, but significantly lowered heart rate and TOI. During the TTE, wearing either LBCG significantly (P < .05) increased HHb concentration, whereas wearing uLBCG also significantly (P < .05) increased nTHI. No improvement in endurance running performance was observed in either compression condition. Conclusion: The results suggest that wearing LBCG facilitated a small number of cardiorespiratory and peripheral physiological benefits that appeared mostly related to improvements in venous flow. However, these improvements appear trivial to athletes, as they did not correspond to any improvement in endurance running performance.]]> Sat 24 Mar 2018 08:04:42 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27900 2max), anaerobic power and capacity, muscular strength, body composition, muscle fibre characteristics and metabolic efficiency. Despite these age-related changes, several studies have demonstrated that the continued training and competition undertaken by masters athletes slows the natural ageing-related reductions in both athletic performance and physiological function. It should also be highlighted that many other non-physiological age-related changes occur that contribute to the decline in masters athlete performances (e.g. social circumstances, family commitments, employment situations and musculoskeletal limitations). Regardless, it is well understood that athletic performance decreases with age across endurance, sprint and strength events after approximately 35-40 years. These highlighted losses in physiological function and performance accelerate rapidly after an individual reaches 70 years of age.]]> Sat 24 Mar 2018 07:38:01 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49570 Mon 22 May 2023 09:41:09 AEST ]]>
