The Barna,
with data

Six conclusions that hold up the whole document

1. Development first is not ideology: it is what the evidence says. Enjoyment predicts staying in sport (r = 0.45) almost three times better than competitive performance (r = 0.18), and 92.8% of those who stand out at junior level are not those who stand out as seniors. A club that retains players by winning is using the weakest lever there is.
2. The model has a famous, documented precedent. Marc Gasol founded a school in 2014 —not a team— and did not create his first senior side until 2017. Thirteen verified public items, from 2014 to 2026, sustain his doctrine: «We start with the utmost humility, with commitment, effort and a methodology of our own» and «We are not going to rush to reach the ACB».
3. The Barna is the third largest development structure in its comparable field. 32 teams federated with the FCBQ in 2026-27 (28 youth + 4 senior). Only Boet Mataró (42) and UE Mataró (37) register more — and of the three, the Barna is the only one without a team in the FEB categories.
4. The leading development club in the city of Barcelona for digital community. 7,096 followers, 6th of 22 verified Catalan and Spanish development clubs. The five ahead are all from the metropolitan area, not from the city.
5. Where others need two or three organisations, the Barna does it with one. Barça, Girona, Manresa, Sant Adrià, Cornellà and L'Hospitalet split men's, women's and youth basketball across separate legal entities and accounts. The Barna covers everything under a single brand: for a sponsor, a single point of entry to the whole community.
6. The ceiling is not the structure, it is the conversion. 222 followers per federated team, against Sant Adrià's 532 or Almeda's 455. The structure is already built; what is missing is editorial identity.

A doctoral-level review

A summary of a doctoral-level literature review on the youth basketball club: eleven parallel lines of research, more than 900 searches of academic search engines, institutional repositories, bibliographic APIs and primary federation, legal and government sources. The full report runs to ~61,000 words and eighteen chapters.

It covers the psychology of the young athlete, dropout, talent development, maturation and health, parents and coaches, child protection, the sociology of the club, international models, management and governance, sport theory, gender and feminism, and the economics of basketball clubs. It includes a map of Catalan basketball and a chapter applied to CB Grup Barna.

Its distinctive feature is traceability. Every reference carries a verification mark, and Annex III lists exhaustively what could not be verified — including five widely circulated figures in the sector that must not be cited.

The fifteen findings that matter most

On dropout

On talent

On health and club culture

On the economics

On gender and management

The best documented cost-impact ratio

Three independent lines converge with it: the coach is the dimension that most predicts retention in Spanish sports centres; the caring/transformational climate outperforms every other predictor of youth outcomes (r = 0.43, across 177 studies); and in the SPLISS model, the pillar that sets Serbia and Lithuania apart is not funding but coach education.

A necessary caveat: a four-month Spanish study cut punitive behaviour by more than half without improving the climate as perceived by the players, and two systematic reviews note that institutional maintenance is almost never documented. Training once is not enough: it has to be recurrent and the climate has to be measured as the players perceive it, not by coach attendance.

The ten recommended moves

Eight of the ten cost nothing or next to nothing. None requires promotion to a higher category. And none depends on winning.

What can be stated before the Board, the District and sponsors

What can be stated

• TEAM sport behaves in the opposite way to individual sport with regard to adolescent mental health: −10% in anxiety/depression, −19% in depressive symptoms with withdrawal and −20% in rule-breaking behaviour in girls, against +16% anxiety/depression in individual sport (n = 11,235). It is the most specific argument available to a basketball club.
• The social value of an active child is almost double that of an active adult: £4,300/year (ages 11–16) against £2,600.
• A volunteer generates more than twice the social value per head of a participant (£2,663 against £1,274).
• The social return of sport has a methodologically published measure: SROI of 1.91 (2019), 3.28 (2020) and 4.38 (2025) per pound invested.
• The fabric of clubs is inherited capital and is not reproducible. A club with sixty-one years of history in the Clot is not an interchangeable service provider.
• In Sant Martí the income gap between neighbourhoods of the same district is almost 3:1 (Vila Olímpica +41% on the Barcelona average; el Besòs i el Maresme −63%). Fees, equipment and travel are not administrative details: they are the barrier.
• Basketball is the Spanish team sport with the best gender trend: 36.1% women's licences in 2025, with female growth that in 2024 more than doubled the male figure.

What must not be stated

• That taking part in sport causes integration, better educational performance or better mental health. The designs are mostly cross-sectional and the effects small (10–20%).
• That sport improves grades. The effect on academic performance is mixed; the solid effect is on sustained attention behaviour in the classroom (d = 0.77) and on self-esteem. It is a better argument and it also happens to be true.

The defensible formulation is Coalter's: sport is a necessary but not sufficient condition. What produces the effects are the sustained social relationships and the complementary supports the club organises around the sport.

Five figures that circulate and must NOT be cited

The sentence that sums up the work

A tool. Not a miracle. What it produces depends entirely on how it is used — and that is, precisely, the responsibility and the opportunity of a development club.

Eleven lines of research, eighteen chapters, three annexes

1. Psychology of the young athlete Motivation, motivational climate, self-determination; why enjoyment predicts persistence and performance does not.
2. Dropout from sport The real age (12.93), the under-14→under-16 transition, the 30% annual dropout from at least one club, and the specific case of female dropout as environmental expulsion.
3. Talent development Early identification (the 92.8%), the relative age effect (50.3%/6.8%), early specialisation and its alternatives.
4. Maturation and health PHV (range 12.8–16.5 years in a preselected academy), injuries and the neuromuscular warm-up (−36%), training load.
5. Parents and coaches Parental behaviour (basketball, the worst sport analysed), presence as retention (86% vs. 58%), and behavioural training for coaches (26%→5%).
6. Child protection LOPIVI, the European CASES project (78.1% / 69.4% / 85%), the protection officer, club culture.
7. Sociology of the club The club as inherited, non-reproducible social capital; volunteering (~84% of the value on boards); the board as the dominant constraint.
8. International models The SPLISS model; why Serbia and Lithuania stand out for coach education and not for budget.
9. Management and governance Professionalisation, theory of change, the annual report as a funding instrument.
10. Sport theory Bourdieu (capital and field), Elias (the civilising process and sport), the sport ethic of Hughes and Coakley (overconformity), and Bronfenbrenner (the ecological model of development). The framework that explains why burnout is organisational and not individual.
11. Feminism and gender From Ann Hall and Iris Marion Young to Messner and Theberge; gender-bland sexism; the obligations of Law 39/2022. The most usable part: Young translated into technical objectives on court — «the ball is coming for me», discontinuous unity in the shot, occupying space as a season objective.

Plus the cross-cutting chapters: chapter 11 devoted to Marc Gasol (Part III), the promotion dilemma (ch. 14), the map of Catalan basketball (ch. 15), the chapter applied to CB Grup Barna, the 12-chapter editorial series (§17.12) with the table of which evidence backs each piece, and the three annexes.

The promotion dilemma

With the official FEB and ACB figures: the discontinuous cost ladder (×5 at the first national step; from Tercera to Primera FEB the fee ×36 and the bond ×19) and the two documented cases that are precisely the club's thesis:

• Força Lleida, 2024. Promotion of the men's team to the ACB was financed, among other things, by withdrawing the women's team from Liga Femenina 2.
• Betis / Baloncesto Sevilla, 2023. It cut €2.6m by eliminating two youth teams and the under-12 and under-10 age groups — and still ended up in insolvency proceedings in 2026 and the club disappeared.

The chapter's operational conclusion: the written promotion policy with a financial threshold and a no-cannibalisation clause (move no. 5) exists so that this cannot happen to the Barna.

The map of Catalan basketball

The national-level clubs were fully verified; the regional ones only partly, because the FCBQ website blocked automated access with a captcha. The chapter's most striking figure: there is not a single Catalan club in Primera FEB.

This line was completed later with the report «Piràmide CB Grup Barna» (13/08/2026, from basquetcatala.cat club pages): 33 federated Barna teams against the 23 youth teams of the Fundació Bàsquet Girona, the 40 of Boet Mataró (without a women's senior B) and the 24 of Santfeliuenc — with the Barna the only one of the four with two senior teams (A+B) in both genders within the same organisation.

What the research leaves flagged as pending

Annex III, besides the five prohibited figures (Part I·6), leaves three matters open that can be settled with a phone call, not with more research:

• The exact category of the CBGB this season (settled later: both senior A teams in the FCBQ Super Copa, confirmed by El Clotenc and the federated calendar).
• The FCBQ's fees (the public website blocks automated access).
• The applicable grant calls (the public domains block automated access).

Interviews and statements, 2014–2026

The Gasol model in five ideas, all sourced

• The school first, the team afterwards. He founds the school in 2014; the first senior team does not arrive until 2017 (EBA). Three years of youth work before a single senior side. (FEB 2014 and 2017; Esport3)
• Three principles, not a slogan: effort, commitment and methodology — a methodology «of our own», shared across every age group. (FEB 2014, 2017; the club's lecture at the UdG with Jesús Escosa and Marc Pena)
• No rush, even when winning: «We are not going to rush to reach the ACB» — said weeks before winning promotion. The pace is set by solidity, not by the result. (HoyMagazine 2022)
• The person before the sport: «Basketball is not as important as the message we can send to the younger generations to inspire them to be good people.» (El Desmarque, 2019)
• Sport as an educational tool: «L'esport és una eina per educar» — the formulation the Barna's research chose to sum up the whole piece of work. (CBGB thesis, 2026)

It is, point by point, the same order CB Grup Barna defends in its projecte esportiu — with the measurable difference that the Barna has been doing it for sixty-one years and keeps youth and senior basketball within the same organisation.

22 development clubs, ranked

Development organisations with a youth system, a territory and a community of families — the correct point of comparison for the Barna. The 2nd edition adds UE Mataró (which takes the lead), L'Hospitalet, Santfeliuenc, Roser and the separate sections of Cornellà and Sant Adrià.

The gaps

The five clubs ahead are from the metropolitan area, not the city of Barcelona. Within the city, the Barna leads CB L'Hospitalet —which is from L'Hospitalet— by 555: the second club strictly from the city is Laietà, 1,794 behind (+34%).

The Barna in the national standings

In LF Endesa: 11th of 16 by digital community, ahead of the champion (Valencia, women's account, 6,954) and of five elite clubs. In LF Challenge and LF2, 4th in both.

From 9th to 18th unchanged (Al-Qázeres 4,027 … Melilla 162). Excluding umbrella accounts and feeder teams of ACB clubs, the Barna leads the category among comparable clubs.

From 9th to 24th unchanged (TGN 4,850, Viladecans 4,802, Móstoles 3,725, Manresa CBF 3,560 … Stadium Casablanca 1,102), with GEiEG updated to 1,343. Figures still pending: Siroko Gijón, ADBA Sanfer, CB Isla Bonita and El Cochinillo Segoviano — none showing any sign of exceeding the Barna's 7,096.

The table that does not depend on communications

«Youth» = under-18 down to under-10. «Seniors + u20/u25» includes senior teams in any category plus under-20/under-25 sides. A team registered in two competitions (league + Super Copa) counts once per listed registration.

The map of legal entities: exactly who you are comparing against

Several famous names in Catalan basketball are not one club: they are two or three federated entities with separate accounts. Adding their figures together —or comparing against the wrong one— is the quickest way to inflate or sink a ranking.

Four honest readings

The 2026/27 ladder

The sentence for the sponsorship pack

To that sentence, the block of evidence in Parts I to III adds the why: it is not only that the club is big, it is that the way it develops players —enjoyment before results, no early cuts, with a complete pathway— is the one the research supports and the one a project like Marc Gasol's chose when it could have chosen any other.

The discrepancies between sources, and which one prevails

This report merges three studies carried out on different dates and with different criteria. Some figures do not match between them. Hiding that would make the document useless to anyone who checks: this is what differs and what has been adopted.

Other corrections already incorporated

• UE Mataró: no figure in the 1st edition of the benchmark → 9,225 verified. It changes the leadership of the development ranking and moves the Barna from 5th to 6th.
• Barça CBS Femení: omitted in the 1st edition → 18,400. The Barna goes from 3rd to 4th in LF Challenge.
• L'Hospitalet's women's account: the account @celhospitaletfemeni (2,952) belongs to CE L'Hospitalet football. The basketball one is @ce_joventut_lhospitalet (513).
• Uni Girona: no longer an independent club; its LF Endesa licence sits under CB Girona 2014 SAD.
• «Marta Zori renews with Grup Barna» (FEB.es): it appeared in an external press round-up. It could not be verified by any route and is not used in this report or on the club's website.
