Cullen, BD, Cregg, CJ, Kelly, DT, Hughes, SM, Daly, PG, and Moyna, NM. Fitness profiling of elite level adolescent Gaelic football players. J Strength Cond Res 27(8): 2096-2103, 2013-The purpose of this study was to evaluate the anthropometric characteristics and fitness levels of elite level under 18 (U-18) Gaelic football players to establish normative centile scores for selected fitness parameters and to compare the physical and fitness characteristics relative to each playing position. A total of 265 male U-18 Gaelic football players (age: 16.96 ± 0.7 years; height: 178.11 ± 6.27 cm; weight: 72.07 ± 8.68 kg) participated in the study. According to positional roles, players were categorized as goalkeepers (n = 13), defenders (n = 113), midfielders (n = 30), and forwards (n = 109). Height and weight were measured, and skinfolds were taken before participants sequentially performed a sit and reach test (S&R), countermovement jump (CMJ), standing long jump (SLJ), 5- and 20-m speed test, and the Yo-Yo Intermittent Recovery Test Level 1 (YYIRT1). The percentage body fat was higher (p < 0.01) in goalkeepers than the other playing positions. Goalkeepers had a higher body mass index than defenders (p < 0.05) and forwards (p < 0.01). Midfielders and goalkeepers were taller (p < 0.01) and heavier (p < 0.01) than defenders and forwards. The total distance covered in the YYIRT1 was significantly lower (p < 0.01) in goalkeepers than the other playing positions. There was no significant positional difference in the performance scores in the S&R test, CMJ, SLJ, and 5- and 20-m running speed. The study findings indicate minimal differences in the anthropometric and physiological characteristics between playing positions in elite youth level Gaelic football players. The norm-referenced percentile scores will enable conditioning coaches to benchmark elite performance and design training programs.

Characteristic types of actions and training/matches loads of football goalkeepers show that goalkeeper’s performance differs from other football’s formations. Such situation may predispose to the occurrence of other kinds of injuries in this position. The aim of this study was to analyse epidemiology of injuries in young football goalkeepers.

Competition related dietary intake has not yet been investigated in Gaelic football. The present study examined the pre-competition macronutrient intake of elite male Gaelic football players. Forty players from two teams completed a food diary on the two days preceding competition (DAY-1 & DAY-2) and on match date pre-match (MATCH-DAY). Carbohydrate intake was significantly greater on DAY-2 compared to DAY-1, for both absolute [295 ± 98 vs. 318 ± 77 g] (p = 0.048; -23.6 g [-47.3 to 0.2]; Cohen’s d = 0.27) and relative intake [3.4 ± 1.1 vs. 3.7 ± 1.0 g.kg-1] (p = 0.027; -0.3 g.kg-1 [-0.6 to -0.03]; Cohen’s d = 0.32). The number of players in accordance with and not in accordance with the guidelines for carbohydrate intake on DAY-2 was significantly different to an expected frequency distribution [χ2 (1) = 32.400; p = <0.001; ϕ = 0.9] with a greater number of players not meeting the guidelines [observed N = 2 vs. 38]. The number of players in accordance with and not in accordance with the recommendations for carbohydrate intake on MATCH-DAY was significantly different to an expected frequency distribution [χ2 (1) = 8.100; p = 0.004; ϕ = 0.45] with a greater number of players meeting the guidelines [observed N = 29 vs. 11]. The major finding from the current investigation was that a significantly greater number of players did not meet carbohydrate intake guidelines on the day before competition. Individualised nutritional interventions are required in order to modify current pre-match dietary intake.

The use of sand has been suggested as fitness-enhancing surface in field-based team sports. However, concerns have arisen in regard whether physical responses associated to sand training are sport-specific. We compared physical and technical demands during small-sided football games (4v4 + goalkeeper; SSGs) played on artificial turf and on sand.

Gaelic football is indigenous to Ireland and has similar locomotion profiles to soccer and Australian Football. Given the increasing attention on long-term player development, investigations into age-related variation in Yo-YoIR1 performance may provide useful information in talent identification, programme design, and player monitoring. Therefore, the aim of this study was to evaluate Yo-YoIR1 performance across Gaelic football age groups. Male participants (n = 355) were recruited from division one, Gaelic football teams. Participants were allocated to one of seven groups according to respective age groups from under 13 (U13), under 14, under 15 (U15), under 16 (U16), minor, under 21 (U21), to senior age groups. Total Yo-YoIR1 distance (m) increased progressively from U13 (885 ± 347 m) to U16 (1595 ± 380 m) equating to a rate of change of 180.2%. In comparison to U13, total distance at minor (1206 ± 327 m) increased by 136.4%. Subsequent increases were observed in U21 (1585 ± 445 m) and senior players (2365 ± 489). Minimum (800-880 m) and maximum (2240-2280 m) total distances were comparable for U15, U16, and U21 players. Differences in total distance (m) for all age groups were statistically significant when compared to U13 players (p<0.002). In comparison to U13 players the magnitude of differences between age groups for total distance were deemed to be large (ES >0.8). Similar trends were observed for maximum velocity and estimated VO2max. The evolution of Yo-YoIR1 performance in Gaelic football players from adolescents to adulthood highlights how maturation may influence sport-related running ability. Changes in Yo-YoIR1 performance should be closely monitored to optimise interventions for individuals transitioning across age groups.
