Interdisciplinary Communication: How Sport Scientists Connect the Performance Team

Prerequisites: This article assumes familiarity with the sport scientist’s role within a high-performance unit and the principles of evidence-based practice. If any of these topics are new to you, start with:

• Sport Scientist as Decision Facilitator in the HPU
• Evidence-Based Practice and Decision-Making in Sport Science

Learning Objectives

• Distinguish the conceptual difference between an interdisciplinary team (IDT) and a multidisciplinary team (MDT), and explain the sport scientist’s unique role within an IDT.
• List the five pillars of the Department of Methodology (DoM) and explain how each pillar influences team communication.
• Design audience-tailored data delivery strategies for different stakeholders within a performance team.
• Identify barriers to IDT collaboration — silos, power dynamics, and professional bias — and propose mitigation strategies.
• Discuss the evidence-based impact of psychological safety and professional intimacy on IDT communication quality.

Multidisciplinary vs Interdisciplinary: One Word, Two Cultures

A multidisciplinary team (MDT) places experts from different disciplines side by side, each working within their own professional boundary. The structure reflects the sum of its parts but does not necessarily reflect the relationships between them. An interdisciplinary team (IDT), by contrast, pools expertise into a unified plan. Team members contribute their specialist knowledge collectively toward integrated, athlete-centred goals, producing services that are more condensed, more specific, and more targeted (French, 2022).

The distinction matters because many practitioners believe they work in an interdisciplinary manner when, in practice, they operate multidisciplinarily (French, 2022). A team can employ staff from sport science, medicine, nutrition, psychology, and coaching — yet if each discipline submits independent reports without shared planning, the structure remains multidisciplinary regardless of what it is called.

Four organisational structures commonly frame performance support teams. A top-down hierarchy places a chief medical officer or head of department at the apex, directing all technical areas below. A divisional organisation arranges disciplines in parallel silos under a performance director — the most common structure today, but inherently reductionist. A matrix organisation forms cross-discipline project teams around specific problems (e.g., hamstring injury prevention). A flat organisation treats all disciplines as equal contributors under a universal performance goal, enabling situational leadership where the most relevant expertise leads at any given moment (French, 2022).

A practical starting point is to diagnose where an organisation sits on the MDT–IDT spectrum. If meetings consist of sequential departmental updates with no shared action items, the team is likely operating as an MDT regardless of its stated structure. Interdisciplinary support is not an organisational chart — it is a mindset that prioritises collective problem-solving over parallel expertise (French, 2022). The ecological dynamics framework reinforces this view: traditional reductionist approaches isolate each discipline, while a systems-based perspective recognises circular causality, where all internal and external factors interact reciprocally across the performance system (Rothwell et al., 2020).

MDT-to-IDT transition cannot be imposed through structural change alone. Renaming a department does not alter the behaviours within it. Without shared principles, shared language, and genuine relationship investment, a structural shift produces cosmetic change at best.

The Bridge Builder: Where the Sport Scientist Stands in the IDT

The sport scientist occupies a unique position within the IDT. Rather than operating within a single silo, the sport scientist works horizontally across the entire team structure, collecting, synthesising, and reporting information from all stakeholders (French, 2022). The fundamental role is to build an evidence base that helps coaching staff make informed decisions about athlete preparation and competition.

This bridge function extends in two directions. Internally, the sport scientist connects technical coaches, medical staff, strength and conditioning practitioners, nutritionists, and psychologists. Externally, the sport scientist facilitates partnerships with academic institutions and evaluates the validity and reliability of equipment and software from vendors (French, 2022).

Critical thinking underpins this bridge role. Its three components — empiricism (relying on repeatable empirical evidence), rationalism (using logical reasoning rather than wishful thinking), and scepticism (continuously questioning accepted conclusions) — form the intellectual foundation for sound decision-making within the IDT (French, 2022). Without these habits, the sport scientist risks becoming a data reporter rather than a decision facilitator.

Applied performance analysts exemplify this integrative function. Martin et al. (2023) describe performance analysts as value co-creators who operate as curators, translators, and educators within the performance ecosystem. Embeddedness — the depth of a practitioner’s integration into an organisation’s relationships, context, and service delivery — is the primary enabler of effective practice. Embedded practitioners build three assets: relationships with stakeholders, credibility through consistent delivery, and contextual intelligence, an understanding of the political, cultural, and operational landscape in which they work (Martin et al., 2023).

Skill acquisition specialists illustrate another form of bridging. Otte et al. (2024) describe the skill acquisition specialist as a cross-departmental connector who can lead a Department of Methodology, serve as a coaching consultant, and function within individual development planning as an upper guide, active analyst, coach supporter, and connector between staff and athletes.

Modern practitioners must be skilled generalists — not because specialisation is unnecessary, but because broad knowledge enables effective communication across disciplines (Walker et al., 2023). The sport scientist’s role is not to make decisions for coaches but to support decisions by translating complex data into actionable information. The distinction between deciding and facilitating decisions defines the boundary of the role.

Speaking the Same Language: Five Pillars of the Department of Methodology

A Department of Methodology (DoM) is a framework designed to coordinate transdisciplinary sport science support through shared principles and a common language (Rothwell et al., 2020). Originally proposed as a conceptual model grounded in ecological dynamics, the DoM has since been developed into an actionable implementation framework through expert consensus research.

Hydes et al. (2026) conducted a three-round Delphi study with 80 high-performance experts (mean experience: 17.5 years, representing 16 countries). Of 114 statements generated, 108 (94.7%) reached consensus. Five pillars of implementation emerged:

Pillar	Core Actions	Consensus
Building a shared language	Co-produce a practical glossary; align terminology with organisational vision	82.4%
Building common principles	Define roles clearly; ensure psychological safety; respect diverse perspectives	100%
Working collaboratively	Understand coaching intent; communicate across discipline boundaries; share workspaces	91.3%
Continuous knowledge exchange	Hold regular pre/post-training and match meetings; use sessions as knowledge-sharing opportunities	100%
Collaborative practice design	Involve all DoM members in session design; include athletes in planning; use performance analysis to inform representative task design	93.8%

The first pillar — shared language — is foundational. When a sport scientist says “high-intensity running” and a coach understands a different threshold, the message is lost regardless of its accuracy. A co-produced glossary ensures that every stakeholder interprets the same term in the same way. Digital platforms (shared folders, dashboards, communication apps) serve as infrastructure for maintaining this linguistic alignment (Hydes et al., 2026).

The Queensland Reds rugby programme provides a practical illustration. When coaching, performance analysis, and physical preparation staff adopted shared ecological dynamics principles, they collaboratively identified that unstructured possession was the most common source of ball retention. This shared understanding led to redesigned training environments emphasising self-organisation, adaptation, and competition — contributing to three Super Rugby finals appearances and a championship title (Rothwell et al., 2020).

Shared language is a precondition for shared behaviour, not a substitute for it. A glossary alone does not change culture. It must be accompanied by the remaining four pillars — common principles that establish role clarity and psychological safety, collaborative work that crosses discipline boundaries, continuous knowledge exchange through structured and informal meetings, and joint practice design where session planning is a collective responsibility rather than a coaching prerogative. The expert panel identified power dynamics, interpersonal relationships, entrenched disciplinary norms, and remote working as ongoing barriers to DoM implementation (Hydes et al., 2026).

From Chaos to Clarity: IDT Leadership and Psychological Safety

Leading an IDT requires simultaneous attention to two domains. King et al. (2026) interviewed eight elite sport leaders (mean experience: 15 years across international football, rugby, cricket, and Olympic sports) and identified a people domain and a context domain. In the people domain, leaders build professional intimacy — close, trust-based relationships with each team member — and set the tone for a high-performance atmosphere. In the context domain, leaders navigate complexity, exercise judgement under uncertainty, and solve performance problems.

Vertical organisational structures can create silos and inter-disciplinary competition (King et al., 2026). Leaders who recognise this risk adopt horizontal integration models where expertise is distributed. Holacracy — a flat organisational approach that distributes authority across the team — promotes four principles: lean and adaptive operations, highly effective collaboration, clearly distributed authority, and purpose-driven work (French, 2022).

Within a holacratic structure, situational leadership becomes possible. At any given moment, the discipline with the most relevant expertise takes the lead. Once the problem is resolved, the team returns to its flat structure. This flexibility prevents any single discipline from dominating the agenda and ensures that leadership reflects the issue at hand rather than a permanent hierarchy (French, 2022).

Psychological safety — the belief that one can speak honestly without fear of punishment or humiliation — is described as “the soil in which culture grows” (Marsh et al., 2023). Teams that avoid conflict miss opportunities to learn and grow. Psychologically safe high-performance organisations confront problems directly, seeking solutions rather than assigning blame. When conflict is managed constructively, it functions as a learning mechanism. Unmanaged conflict, however, escalates through emotional contagion, where negative emotions spread from the individuals involved to the wider team (Marsh et al., 2023).

Leaders can apply influence tactics along a hard–soft spectrum. Hard tactics (requesting, legitimising, coalition) suit routine tasks and urgent situations. Soft tactics (rational persuasion, consultation, inspirational appeals) are more effective in complex, ambiguous situations — precisely the conditions that characterise IDT problem-solving. The outcome depends on the approach: hard tactics tend to produce compliance, while soft tactics build commitment (Marsh et al., 2023).

Current evidence on IDT leadership in elite sport is predominantly qualitative, drawn from small samples of experienced leaders. Psychological safety research in sport remains largely borrowed from organisational psychology, with limited sport-specific validation. These frameworks should be treated as guiding principles rather than prescriptive formulas, adapted to the specific organisational context and culture in which they are applied.

In Their Language: Data Delivery and Information Dissemination

Data delivery is not about producing reports. It is about optimising the decisions of the people who receive those reports. A survey of 206 senior football practitioners across six FIFA confederations found that scientific literature was the least preferred evidence source across all departments, regardless of tier or competition level (Dello Iacono et al., 2025). Spreadsheets were the most commonly used tool for both data organisation (76%) and reporting (62%). Summary tables appeared in 92% of reports.

These findings confirm a well-documented gap between research and practice. Coaches prefer peer discussion (42%), books (12%), and observation of other coaches (11%) over journal articles (approximately 2%) as sources of coaching knowledge (Le Meur, 2022). The research-to-practice lag is estimated at approximately 17 years (Le Meur, 2022). The medium through which information is delivered determines whether it reaches the intended audience.

Pre-attentive attributes — visual properties processed within 200 milliseconds — form the perceptual basis of effective data visualisation. Colour, form, spatial position, and movement are the four attributes that users process unconsciously before deliberate attention engages (Bosch & Tran, 2022). Gestalt principles (proximity, similarity, continuity, closure) explain how humans infer organisation and relationships from visual information. Effective visualisations leverage these cognitive mechanisms to make patterns immediately apparent.

Universal design — the principle that products should be usable by people of all ages and abilities — applies directly to sport science reporting. Seven principles (equitable use, flexibility, simplicity, perceptible information, error tolerance, low effort, appropriate sizing) guide the creation of visualisations that work for coaches on the training pitch and analysts in the office alike (Bosch & Tran, 2022).

Three practical steps structure the reporting process. First, select the information that matters — different stakeholders have different priorities. Sport scientists focus on workload and wellness, medical staff on injury status, coaches on match preparation (Le Meur, 2022). Second, match the format to the audience — some prefer visual reports, others verbal briefings; some want tables, others want graphs. Third, keep reports “simple but powerful” — three to four key bullet points, traffic light systems where appropriate, and minimal noise (Le Meur, 2022).

Information presented as an infographic is 6.5 times more likely to be remembered than text alone (Le Meur, 2022). The 13 guidelines for effective infographic production — starting from coaches’ questions, critically reviewing the original research, indicating evidence level, limiting jargon, and emphasising practical implications — offer a structured approach to translating complex data into accessible formats.

The risk of simplification is that nuance is lost. A traffic light system reduces a complex physiological state to three colours, potentially obscuring meaningful within-category differences. Effective practitioners manage this trade-off by layering information: a simplified dashboard for daily briefings, with detailed data available on request for those who want to probe deeper. Information dissemination is psychology — it begins with understanding how the target audience thinks and acts, then designing the delivery to match (Le Meur, 2022).

Breaking Down Walls: Barriers and Solutions for IDT Collaboration

Six recurring barriers obstruct IDT collaboration: silos, where disciplines operate in isolation; power dynamics, where hierarchical status distorts communication; professional bias, where practitioners privilege their own discipline’s perspective; role ambiguity, where unclear responsibilities create overlap and conflict; remote working, which reduces informal interaction; and low utilisation of scientific literature, which limits the evidence base for shared decision-making (Hydes et al., 2026; Dello Iacono et al., 2025).

The Football Performance Support Model addresses these barriers through three integrated layers: philosophical alignment, key performance indicators, and team member attributes (Mason et al., 2026). Philosophical alignment requires coherence between the club’s vision, the manager’s approach, and the interdisciplinary team’s methods. When these three elements are misaligned, departments pursue contradictory goals, creating friction and silo behaviour. The Performance Director (PD) plays a critical role in facilitating this alignment by connecting all support functions under a unified performance vision (Mason et al., 2026).

KPIs must be aligned across departments. When the sport science department tracks workload metrics while the medical department tracks availability metrics without shared interpretation, conflicting recommendations emerge. Effective KPIs are anchored to the club’s vision and the coaching staff’s tactical objectives (Mason et al., 2026).

Team member attributes extend beyond technical expertise. Three knowledge domains define an effective IDT contributor: professional knowledge (discipline-specific competence), interpersonal knowledge (communication, empathy, relationship-building), and intrapersonal knowledge (self-awareness, self-regulation, reflective practice). Effective IDT communication depends on all three (Mason et al., 2026).

Shared mental models (SMM) offer a decision-making framework that promotes consistency across a multidisciplinary team. When an organisation defines what successful performance looks like, establishes agreed evaluation criteria, and uses common language to describe athlete profiles, evaluative disagreements become productive rather than divisive (Barraclough et al., 2025).

The GRPI model (Goals, Roles, Procedures, Interpersonal Relationships) provides a diagnostic tool for identifying where team dysfunction originates. When goals are unclear, role confusion follows. When roles are clear but procedures are absent, interpersonal conflict escalates. Addressing each layer in sequence — goals first, then roles, then procedures, then relationships — prevents teams from treating symptoms rather than causes (Marsh et al., 2023).

Martin et al. (2021) reinforce this layered perspective through a professional practice framework for applied performance analysis. Nine components of practice — from establishing relationships and defining roles through to service review and evaluation — are supported by five areas of expertise: contextual awareness, relationship building, performance analysis expertise, technical expertise, and professional behaviours. Contextual awareness and relationship building are the foundational layers. Without them, technical expertise has no pathway to influence.

Integration begins with relationship investment, not structural change. The sport scientist who is perceived as a resource rather than a constraint earns the credibility to influence decisions, challenge assumptions, and translate evidence into practice (Le Meur, 2022). Alternative approaches to overcoming IDT barriers — such as embedding staff in shared physical workspaces, establishing regular cross-departmental review meetings, and building data-informed (rather than data-driven) decision cultures — all share a common prerequisite: genuine, sustained investment in professional relationships.

Key Takeaways

• MDT places experts side by side; IDT pools expertise into a unified plan. The shift from multidisciplinary to interdisciplinary practice is a mindset change, not a structural one.
• The five DoM pillars — shared language, common principles, collaborative work, continuous knowledge exchange, and collaborative practice design — form an actionable integration framework endorsed by 94.7% expert consensus across 80 high-performance professionals.
• Data delivery is not report production but decision optimisation. Coaches prefer journals at approximately 2%, making communication redesign — through audience-tailored formats, infographics, and simplified reporting — essential for impact.
• Silos, power dynamics, and professional bias are the primary barriers to IDT collaboration. Philosophical alignment, embeddedness, and shared mental models provide systematic counter-strategies.
• Psychological safety is the prerequisite for IDT communication quality. Leaders cultivate it through professional intimacy, constructive use of conflict, and distributed authority that allows situational leadership to emerge.
