Acute fuelling and refuelling practices of male academy soccer players: implications for physical development and performance
(Akute Energieversorgung und Essgewohnheiten von männlichen Akademiefußballspielern: Auswirkungen auf die körperliche Entwicklung und Leistung)
INTRODUCTION:
The energy expenditure of male adolescent soccer players [1] from the English Premier League (EPL) is comparable to (or greater) than adult players [2]. Given the requirement to promote growth and maturation in this population, there is a necessity for players to consume sufficient energy and macronutrient intake (EI) in the hours before and after training. "Under-fuelling" at this time is likely to reduce training performance and may increase the risk of injury to bone and tendinous structures. Accordingly, the aim of this study was to quantify the EI of male adolescent soccer players in the four hours pre- and post-training.
METHODS:
During a 3-day data collection period, youth soccer players from an EPL academy (n = 48; U12, U13, U14, U15/16, U18, U23, all n = 8) self-reported their EI in the four hours pre- and post-training via the remote food photography method. Pitch-based loading was quantified using GPS technology during three (U12, U13, U14) and four (U15/16, U18 and U23) training sessions over the assessment period.
RESULTS:
Total distance was greatest in the U15/16 (6162 ± 1165 m) squad, more than the U18 (5099 ± 1160 m) and U23 (4878 ± 1171 m) squads (both P<0.05). Distance covered by the U12 squad (6057 ± 1494 m) was greater than the U23 squad (P<0.05). No differences were found between the U13 (5931 ± 646 m) and U14 (5715 ± 1978 m) squads compared to all other squads. EI was consumed in closer proximity to the start of training in the U15/16 squad (- 40 ± 28 mins) compared to the U12 (- 91 ± 77 mins), U13 (- 99 ± 63 mins), U14 (- 104 ± 56 mins), U18 (- 114 ± 71 mins) and U23 (- 99 ± 52 mins) squads (P<0.05). There was no difference between the timing of EI between groups post training, (U12: + 56 ± 39 mins; U13: + 50 ± 34 mins; U14: + 39 ± 27 mins; U15/16: + 53 ± 25; U18: ± 54 ± 91 mins; U23: + 70 ± 84 mins). CHO intake pre-training was greater in U12 (1.4 ± 0.9 g.kg-1; all P<0.05) and U13 (1.5 ± 1.0 g.kg-1; all P<0.05) squads compared to U14 (0.8 ± 0.5 g.kg-1), U15/16 (1.0 ± 1.1g.kg-1) and U23 (0.7 ± 0.4 g.kg-1) squads. CHO intake in the U18 group (1.2 ± 0.1 g.kg-1) was not different from any other squad. Post-training relative CHO intake was greater in the U12 (1.5 ± 0.9 g.kg-1; all P<0.05) and U13 (1.6 ± 0.8 g.kg-1; all P<0.05) compared to U14 (0.8 ± 0.4 g.kg-1) and U23 (0.9 ± 0.4 g.kg-1) squads. CHO intake in the U14 squad was less than U15/16 (1.3 ± 0.6 g.kg-1) and U18 (1.6 ± 0.6 g.kg-1) squads (all P<0.05). CHO intake was lower in the U23 (0.9 ± 0.4 g.kg-1) compared with the U18 squad (P<0.05).
CONCLUSION:
When compared with current recommendations to promote high CHO availability before and after exercise, data demonstrate that the present cohort of players under-consume CHO. Given the requirement to promote physical development alongside training intensity in an adolescent population, careful consideration should be given to the "acute" fuelling and re-fuelling practices for elite youth soccer players.
