Long-term athlete development: Foundations and challenges for coaches, scientists & policy-makers
I’m currently in Dublin, at the invitation of the International Rugby Board, to present at their biennial Coach Education Workshop. Topics include rugby safety/risk (as my tweet last night illustrated), the professionalization of coaching, Sevens rugby, and the topic for which I was invited, Long-Term Athlete Development (LTAD).
LTAD has become something of a staple for sports federations, coaches and administrators – in South Africa, there is a veritable alphabet of LT_Ds, including Athletes (LTAD), Participants (LTPD), Coaches (LTCD), with touted “Fs” (facilities), “Ms” (mentors)” and “Rs” (for resources) in the pipeline.
In any event, LTAD is an interesting starting point for discussion, and this is not exclusively for rugby coaches. Of course, my talk was targeted at rugby, but the same conceptual framework has been applied to every sport, and it’s worth debate between scientists, coaches and managers. I take a rather strategic view of this – the specifics have been debated elsewhere, and I think the big picture matters more than the minute details. It’s a question of management strategy as much as it is science.
Below is my presentation. Obviously, it lacks the narrative of me talking through it, but I hope that it makes at least some sense without it. Once you’ve gone through it, I have included some thoughts below, in bullet point form, to sum up the key points regarding LTAD and the challenges facing its implementation.
Here is that presentation, with key points below:
[prezi id=”x7slyijwudpg” html5=1 width=”700″ autoplay=0]
- The purpose of any framework, be it LTAD or any other, is to drive the allocation of resources in an effective and efficient manner. These resources, human, financial or structural, are finite, and the decision must be made about where to invest. Talent ID for sport is a relatively simple question – it asks “Where is the athlete today, who will represent our country in 15 years’ time?” The simple question however has a complex answer, because we need to find him and then develop that potential talent. That requires some important decisions about who does what within a sporting system? How those resources are allocated is the crux of LTAD.
- Talent Identification cannot be formulaic. The biggest oversight or error is to view frameworks such as this as “formulas” for success. Sporting success is multi-factorial, and too complex to obey a single formula. As a result, we look in hindsight at what worked and create models to apply with foresight, but the mistake would be to become too prescriptive or literal. For every rule, there are exceptions, which probably means there is no rule.
- Within a given sport, there exists a pipeline that takes young athletes to higher performance levels with age. A number of questions need to be answered – how young and how old? How are resources applied? What role to coaches and competition play? The volume of the “base” drives the required efficiency in order to achieve the same pinnacle. The answer to these questions is proposed by the LTAD model of Balyi. In the presentation, I depict a summary of the excellent Irish Rugby Football Union model, “Six to Six Nations“. A google search will reveal many other similar applications of LTAD for various sports
[ribbon toplink=true]LTAD: Foundations and concerns[/ribbon]
- LTAD divides the path from a child to a professional into a number of stages. For each stage, the focus, the role of the coach and the responsibilities of the player vary. In the Irish Model, and generally true of LTAD, serious competition is delayed until after adolescence. This has repercussions for where the sport fits in within society, and the management of various stakeholders. In fact, it is this balance between competition (which society demands) and the LTAD proposed delay in competition that is likely to be the source of most “tension”, and thus failure, within the model. This is explained later.
- While conceptually sound, it must be borne in mind that LTAD has not been conclusively proven. Two of the foundations I discuss briefly in the presentation are the “Windows of opportunity” concept, and the 10,000 hour concept.
[ribbon toplink=true]Early exposure, relative age and 10,000 hours[/ribbon]
- It seems quite clear that early exposure is important, but if we select talent too early, we run the risk of making mistakes and voluntarily cutting our player pool down by an enormous amount. The best illustration of this is the relative age effect, where coaches of young children confuse maturity with ability, and so when picking players for teams, make the error of picking relatively older players. A large number of potentially great athletes are thus neglected and never receive opportunities reserved for those “lucky” enough to be born at the right time of year!This is a significant challenge for sports, and may require a rethink about
- The age at which we begin to select teams, and;
- The level of coaching we provide to our best young players compared to those who don’t quite make the cut – I’d argue that the best coaches should perhaps be allocated to the second best players at this age.
- The 10,000 hour concept for success, popularized by Gladwell in “Outliers” and Syed in “Bounce” has very little merit if applied literally to sporting success. What it does do is provide a compelling argument that practice helps performance, but this is so obvious it doesn’t really need to be said to a group of coaches!
[ribbon toplink=true]Delayed high volumes of training predict success[/ribbon]
- Studies have shown that success in the CGS sports (sports where performance is measured in centimeters, grams or seconds) is related to a) delayed specialization, and b) delayed high volumes of training. In other words, athletes who perform higher volumes of training when younger are less likely to become elite. Those athletes who delay this increase succeed. There are a number of possible explanations for this – one is burnout, in athletes who do more when younger. The other is physiological, and this is the one I’ve explained in the presentation above.
[ribbon toplink=true]Physiological determinism and fate[/ribbon]
[headline h=3]The role of physiology/genes[/headline]
- In rugby, as in many sports, physiology plays a crucial role. Even among a very good group of rugby players, who are the best in the country, there is a small but significant difference in stature and mass in those players who go on to become the very best (Springbok players). In rowing, one of the more amazing findings I have seen in recent years, shows that elite female rowers have testosterone levels 112% higher than sub-elite female rowers. One interpretation of this is that if you do NOT have testosterone levels in that range, then no amount of training, no LTAD and no development is going to make you elite – physiology determines your fate. That’s not to say that having high testosterone levels ensures success, but it is a crucial requirement.
- Applying this to rugby, I look at the data of how many rugby players have played at the highest level in South Africa at the age of 13, the age of 16 and the age of 18. Turns out that the conversion of good 13 year olds to good 16 year olds is relatively poor – only 31.5%. From 16 to 18, it’s much better – 76% of young players who play at U/16 level also play at U/18 level.
[ribbon toplink=true]The competition conflict[/ribbon]
[headline h=3]LTAD vs society’s accepted norm[/headline]
- Attitudes to competition provide the greatest barrier to successfully implementing LTAD. If the competition structure places any priority on winning at the junior level, then it directly conflicts with the fundamental of LTAD, which is to delay the importance of winning until after adolescence In South Africa, we have a competition-driven system – compete at 13, compete at 16, compete at 18, and the best come through. It has certainly produced excellent seniors, but may lack efficiency, and possibly, may be detrimental because it ‘writes off’ a good deal of talent at a young age.
[ribbon toplink=true]Five key challenges[/ribbon]
- Given this reality, there are five key challenges facing LTAD:
- How do you identify talent without either destroying it or neglecting it? Talent is destroyed when it is chosen for the wrong reasons. If you pick players at 13 based on size, speed and strength, you pick a temporary advantage. But because it is rewarded by the competitive system, it never needs to develop other attributes. Talent is neglected because late developers often do not receive a look in, and are lost to the sport early because of the way the system has been created.
- How do you maintain healthy competition without providing a conflicting message to coaches? You cannot create and implement LTAD which says “delay competition”, and then have annual competitions for 10 or 13 year olds, the results of which are crucial to future success as a player. That is a mixed message, and the coach will always go with performance.
- How does a sport embracing LTAD affect that sport’s standing in society? The reality is that sport is a big deal, even from young ages. Here in South Africa, high schools look for young children with athletic potential and offer scholarships and potential career paths. At a young age, good athletes are virtually professional and society has come to accept this as “normal”. Implementing LTAD challenges that, and if the entire environment does not also do the same, then it creates a conflict between one sport and another, and even within a sport.
- Who are the other stake-holders in LTAD? It’s simply not reasonable to suggest that one sport have an LTAD programme from 5 up to adulthood. As mentioned, it’s unnecessary because you don’t need 10,000 hours to begin with, and it’s also costly and potentially crippling to place the entire burden on each sport. Therefore, you recognize that other stakeholders, such as parents and government, also play a crucial role, particularly early on when you actually don’t want players to specialize, but rather engage in a number of different sports, learning a range of skills and abilities. This is perhaps the key concept for LTAD.
- How do we change mindsets? In all of this, it’s important to recognize that sporting systems, countries, federations, have a certain inertia. They are giant, sometimes slow-moving bodies and if you stand in the way, you get flattened. Therefore, to successfully implement LTAD, you must address the mindsets and begin to ‘nudge’ them in a different direction. Failing this, LTAD, or any other similar plan, is nothing more than a fantasy of “best-case”, and won’t work in the real world. It will take brave leadership to change the competition structure, for example, and to adopt a no compromise attitude towards youth talent ID and selection, based on current principles. I doubt many will have the stomach for the fight, but that may be what it takes.
A sound concept, LTAD introduces a number of challenges at a system or management strategy level. It also has some debatable physiological concepts, but the debate on those is perhaps too academic and thus not relevant for coaches. It should not be taken too literally or prescriptively, but rather regarded as a framework to guide decisions.
The big picture is where it is far more complex. Certainly, in South Africa, we will have to grapple with whether competition at young ages is the best way to achieve senior success, or whether it is worth the aggravation to change this. There is no evidence, because there are no long-term prospective studies, that help us ‘guess’ how elite performance would change as a result of policy changes at the junior level. However, it seems reasonable to hypothesize that if youth selection is delayed, and if the pool of available talent is kept large for long enough, we will see more viable prospective talents and thus better performance.
Coaching is often referred to a mix of art and science, and LTAD is similar. There is no single path, and this is a debate likely to extend well into the future. Feel free to weigh in below.
