III. Effective Practice

“From the ten coaches I had when I was a youth player, one made me a better player, three didn't do any harm, and if I'd listened to the six others I would have never Become a Professional Footballer"

Marco Van Basten

Do players progress despite of, or because of their development programmes? Is it survival of the fittest or evolution of the most resilient? These questions probe the efficacy of many youth development programmes that are outcome driven and judge the basis of...

I. Introduction

This article aims to bring to the forefront the obligations of the coach in youth player development, and in doing so, challenge current status quo. For the purposes of this article the term “coach” shall not be restrictive to the technical or head coach. Rather, the reader is encouraged to interpret the term more widely to those significant others operating within positions of influence and who have the opportunity to positively influence holistic behaviour change. The overarchin...

IV. Prescription

Whilst the use of small sided games (SSGs) as a conditioning tool within team sport has been successfully implemented in combination with technical outcomes (1), its longitudinal efficacy at eliciting a standardised acute physiological response within a team of heterogeneous physiological profiles has been questioned due to an inherent ceiling effect occurring amongst fitter players (2). It has been argued that in regard to central adaptations a sustained cardiac filling is integ...

III. Anaerobic Speed Reserve

Maximal aerobic speed (MAS) or the velocity associated with V̇O2max (vV̇O2max) can be defined as the lowest velocity that elicits maximal oxygen uptake and has been used ubiquitously to individualise high-intensity interval training (HIT) prescription (1). This can be conceptualised as the maximum sustainable intensity, in contrast to maximal sprinting speed (MSS), that is, maximal attainable intensity. Moreover, the former can be thought of as sustainable force appli...

II. Historical overview

Time-motion analysis has permitted the quantification of external demands in field-based sport, which have in turn been characterised as acylical and intermittent in nature (1). Specifically, repeated sprints in team sport have been shown to last anywhere between 3-6s interspersed by < 21 seconds (1). Additionally, one of the earlier studies investigating metabolic demands on a cycle ergometer reported phosphocreatine (PCr) decrement as a function of repeated sprints (2)....

I. Introduction

Physical preparation in team sport should work towards satisfying two main objectives. Firstly, to increase the athlete’s physical robustness to tolerate the time on task required to master the skills of their sport (1). Secondly, to increase the athlete’s potential to produce energy. The latter concerns developing the necessary physical capacities that underpin the ability to express sport specific skills faster and for longer durations (2). It falls upon the responsibility of th...
