###### Abstract  
The aim of the current investigation was to examine the locomotor performance profile of elite ladies Gaelic football (LGF) players in relation to playing position and quarters of play. Thirty (\(n=30\)) elite LGF players (age: \(24\pm 4\) years, height: \(169\pm 5\) cm, body mass: \(61\pm 4\) kg) were monitored using 10 Hz GPS technology (Playertek; Catapult Sports; Australia) resulting in 145 individual samples collected over 18 competitive matches across the 2021 and 2022 LGF seasons. Locomotor performance was determined across the following variables: total distance covered (TD, m), relative distance (m\(\cdot\)min\({}^{-1}\)), high-speed running (HSR, \(\geq 4.4\) m\(\cdot\)s\({}^{-1}\)), very high-speed running (VHR, \(\geq 5.5\) m\(\cdot\)s\({}^{-1}\)), relative HSR (RHS; m\(\cdot\)min\({}^{-1}\)), peak velocity (m\(\cdot\)s\({}^{-1}\)), percentage peak velocity (%PeakV), accelerations (\(n\); \(\geq 3\) m\(\cdot\)s\({}^{-2}\)), and decelerations (\(n\); \(\leq-3\) m\(\cdot\)s\({}^{-2}\)). Data were classified based on playing position and quarter of play. The greatest TD was covered by half-backs, midfielders, and half-forwards, with these positions covering significantly greater distances than full-backs (\(p<0.05\)). Similarly, half-backs, midfielders, and half-forwards covered the greatest high-speed distance (HSR). When running performance was analysed across quarters, a significant position by quarter interaction was observed for all running performance variables, except peak velocity and percentage peak velocity. A consistent trend for reduced locomotor performance was evident in the second and fourth quarters across all positional lines. The current data provide coaches with the position-specific locomotor requirements of LGF match-play, which can inform the design of training content for LGF players, along with match-day strategies. Given the reduction in locomotor performance observed across the match, performance staff may consider the use of nutritional interventions, rewarm-up strategies, or specific substitution policies to mitigate the decrement in locomotor performance observed across match-play. team sport; running performance; temporal profile; women's sport; GAA 2024 14 7145 14 14 14 14 14 14.14 14.  
players, including a goalkeeper, three full-backs, three half-backs, two midfielders, three half-forwards, and three full-forwards [3; 6; 7; 8]. LGF match-play consists of two halves, each lasting 30 min, and a countdown clock is utilised to manage game time [3; 7]. The game requires complex hand and foot skills such as catching, high fielding, evasion, kicking on the run, and handpassing on the run; these must be executed under extreme pressure from opposition players and at very high speeds, given the rapid movement of the ball during match-play, requiring exceptional hand-eye coordination. Match-play takes place on a field that is approximately 90 m wide and 130-165 m long [3; 6; 7; 8], with H-shaped goal posts at each end [2; 6; 7; 8; 9]; this results in a relative player area of 422-m\({}^{2}\) at any given time when a player is in possession of the ball [1; 2; 3; 4]. Scoring in LGF is as follows: kicking or handpassing the ball over the bar awards one point, while kicking or palming the ball under the bar and into the net scores three points, resulting in a goal. The overall objective of the game is to outscore the opposing team by gaining and maintaining possession to create scoring opportunities [3; 4; 7; 8; 9], while further limiting opposition teams attacking threats through specific tactical defensive set-ups. [3; 4; 7; 8; 9]. The training process for LGF players is professional in ethos but amateur in nature [2; 3; 4]; specifically, these players complete 3-4 pitch sessions per week and 1-2 athletic development sessions per week, in addition to match-play requirements.
