Why Preseason Matters: Position Within the Season and Hierarchical Structure

Preseason is the preparation period within a macrocycle—the only phase where practitioners have near-complete control over the training programme. Unlike in-season blocks constrained by fixture calendars and recovery windows, preseason provides a blank canvas for systematic physical development (Walker et al., 2023). This distinction makes it the single most important planning window of the annual cycle.

The preparation period divides into two sub-phases. The general preparation phase prioritises high training volume at lower intensities, building broad physical qualities such as aerobic capacity and general strength. The specific preparation phase progressively shifts towards sport-specific activities at higher intensities, culminating in match-simulation exercises and trial games (Haff, 2022). This transition follows a graduated continuum where training specificity increases as the competitive season approaches.

Periodisation operates as a flexible scaffolding framework rather than a rigid prescription. The hierarchical structure—macrocycle (season), mesocycle (3–6 weeks), microcycle (typically 7 days)—provides organisational layers for manipulating volume, intensity, and specificity across time (Haff, 2022). Within the preparation period, mesocycles serve as training blocks with defined objectives: an early mesocycle might target aerobic base development, while a later one focuses on high-speed running exposure and match readiness.

The duration of preseason varies considerably across clubs and leagues. Some environments allow only five training days before the first competitive fixture, while others provide three or more weeks of dedicated preparation (Walker et al., 2023). This range demands that practitioners adapt the same principles to radically different timelines. When the transition period between seasons exceeds two to four weeks, the subsequent preparation period typically requires extension to compensate for detraining effects accumulated during prolonged inactivity (Haff, 2022). Trial matches during preseason serve a dual purpose: they function as progress assessment tools and provide competitive stimuli that accelerate specific preparation.

Where to Start: Needs Analysis, Screening, and Fitness Testing

A needs analysis is the systematic process of identifying the physical, physiological, and injury-risk demands of the sport, position, and individual player. Before any training programme is prescribed, the practitioner must establish where each player stands relative to performance benchmarks and injury risk thresholds (Marsh et al., 2023).

The timing and sequencing of preseason testing follow a deliberate logic. On the first day, submaximal assessments—anthropometric measures, body composition, submaximal aerobic tests, and injury risk screening—take priority. Maximal output tests such as sprint assessments, maximal strength evaluations, and high-intensity aerobic protocols are introduced gradually over subsequent weeks as players re-adapt to training stimuli (Marsh et al., 2023). Imposing maximal testing on a detrained body carries elevated injury risk, particularly for players returning from extended off-seasons, injuries, or transfers without recent training history.

Test results are organised through a three-tier categorisation system. Cohort-level tests assess the entire squad and establish team-wide baselines (e.g., aerobic capacity via the 30-15 IFT). Positional assessments address role-specific demands—centre-backs and midfielders might undergo adductor screening, while forwards receive hamstring eccentric strength evaluation. Individual assessments account for personal injury history, biological maturity (particularly in academy settings), and specific deficits identified through prior monitoring (Marsh et al., 2023).

The 30-15 Intermittent Fitness Test (30-15 IFT) holds particular value in preseason because it delivers both profiling and training prescription simultaneously. The V_IFT score—the velocity reached at the final completed stage—serves as an individualised reference for prescribing HIIT intensities. When combined with a separate Maximal Aerobic Speed (MAS) assessment from a time trial, practitioners can distinguish between high-intensity continuous running capacity and the ability to manage direction changes at high speeds (Marsh et al., 2023). For injury risk screening, eccentric hamstring strength below 337 N on the NordBord device signals elevated hamstring injury risk and triggers targeted intervention programming.

Players arriving in detrained states, new signings without access to prior training data, and recently promoted academy players require particular caution. These individuals carry the highest injury risk during the early loading phase. A comprehensive needs analysis identifies not only what to train but also how aggressively loads can be progressed for each subgroup.

Building the Aerobic Foundation: Conditioning Design Principles

Aerobic capacity provides the physiological platform for football performance. Over 90% of the energy demand during a match is met through aerobic metabolism, making VO₂max a foundational performance determinant even in a sport characterised by intermittent high-intensity efforts (Walker et al., 2023). The preseason objective is to build this aerobic base efficiently while progressively introducing sport-specific conditioning.

Three conditioning approaches exist along a specificity continuum. Isolated conditioning separates physical training entirely from technical-tactical content—running-based intervals, cycling, or gym-based aerobic work. Hybrid conditioning combines physical and technical elements within the same session but in distinct blocks. Integrated conditioning embeds physical objectives within game-model-based drills, where tactical, technical, and physical adaptations occur simultaneously (Walker et al., 2023). Most elite programmes move from isolated towards integrated approaches as preseason progresses.

The LSG→MSG→SSG transition model operationalises this progression through game formats. Large-Sided Games (LSG, ≥17 players) generate the highest total distance and high-speed running per minute due to larger pitch dimensions and longer continuous play sequences. They suit the general preparation phase where aerobic volume is the priority. Medium-Sided Games (MSG, 10–16 players) represent a transitional format. Small-Sided Games (SSG, ≤9 players) produce the highest frequency of explosive technical actions—accelerations, decelerations, direction changes, and duels—making them the vehicle for specific preparation (Walker et al., 2023). A linear periodisation model fits this progression naturally: high-volume, lower-intensity conditioning transitions towards lower-volume, position-specific, explosive training as the season approaches.

Conditioning programmes must account for positional differences. Outer players (full-backs, wing forwards) accumulate substantially higher high-speed running volumes than inner players (centre-backs, central midfielders), requiring position-specific drill design or supplementary running doses for certain groups (Walker et al., 2023). Prescribing relative rather than absolute loads—based on individual fitness test results—ensures that the same drill challenges each player according to their current capacity.

A common error in the integrated approach is failing to achieve maximal or near-maximal speed exposure. Game-based formats rarely produce true top-speed efforts because pitch dimensions and player densities constrain acceleration distances. Practitioners must programme supplementary linear sprinting or position-specific drills that deliberately create space for maximal velocity attainment (Buchheit & Laursen, 2022). Without this intervention, players enter the competitive season without the neuromuscular preparation required for match-intensity sprinting—a gap directly linked to hamstring injury risk.

Designing for Strength: Strength-Power Training and Injury Prevention

Strength training in preseason serves two parallel objectives: enhancing force production capacity and reducing injury risk. Strength imbalance ranks as the third most significant internal injury risk factor, and structured resistance training reduces overall injury incidence by approximately one-third and overuse injuries by roughly 50% (Beere et al., 2023).

The force-velocity curve provides the theoretical framework for programming. Training begins at the high-force, low-velocity end of the curve with maximal strength development, progresses through rate of force development (RFD) training, and culminates in high-velocity power work. This sequence reflects a physiological hierarchy: maximal strength underpins RFD, which in turn underpins explosive power output (Beere et al., 2023). Mixed training that combines high-load and high-velocity stimuli within the same mesocycle optimises RFD development more effectively than either approach alone.

Preseason screening establishes each player’s position on the force-velocity continuum. The Dynamic Strength Index (DSI)—the ratio of dynamic peak force to isometric peak force—identifies whether a player’s primary deficit lies in maximal strength or in the ability to express that strength dynamically. Players with low DSI values benefit from power-oriented programming, while those with high DSI values need further maximal strength development before power-focused work becomes productive (Beere et al., 2023).

Exercise selection in elite football programmes converges around a core group. The Trap Bar Deadlift (TBD) appears in 51% of elite programmes and produces superior force, power, and RFD compared to conventional squat and deadlift variations. Other staples include the Romanian Deadlift (RDL, 43%), Rear-Foot Elevated Split Squat (RFESS, 39%), Nordic Hamstring Exercise (NHE, 29%), and Copenhagen Adductor exercise (Beere et al., 2023). Eccentric training features prominently: 88% of practitioners incorporate eccentric modalities, with 78% citing injury prevention as the primary driver. The NHE remains the most evidence-supported exercise for reducing non-contact hamstring injuries.

Within the microcycle, strength sessions are typically distributed by muscle group. A common arrangement places anterior chain work (squats, TBD) on MD−4 and posterior chain work (RDL, NHE) on MD−3, allowing adequate recovery between sessions while maintaining training frequency (Read et al., 2023). As preseason transitions into the competitive season, full resistance training sessions give way to microdosing—high-intensity, low-volume, high-frequency strength stimuli integrated into pitch sessions or performed as brief standalone blocks. This strategy maintains strength qualities within the constraints of match-congested schedules.

Player compliance remains a significant barrier. Time availability, prioritisation of match results over long-term physical development, and limited staff or facility access all reduce adherence. Reframing language—emphasising resilience and availability rather than arbitrary strength targets—and consistent relationship building between strength and conditioning staff and the playing group improve buy-in (Beere et al., 2023).

From General to Specific: HIIT Programming and Match-Specific Transition

High-intensity interval training in preseason follows a “physiology first” philosophy: define the physiological target before selecting the drill format (Buchheit & Laursen, 2022). The six HIIT types classify sessions by the relative stress placed on aerobic, anaerobic, and neuromuscular systems. Type 1 targets aerobic development with minimal anaerobic and neuromuscular strain. Types progress through increasing anaerobic (Type 2–3) and neuromuscular (Type 4–5) demands, with Type 6 representing combined stress across all three systems.

Five delivery formats serve these physiological targets: long intervals (≥1 min work bouts, 95–105% VO₂max), short intervals (<60 s bouts, 90–105% V_IFT), repeated sprint training (RST, 3–10 s all-out sprints), sprint interval training (SIT, 20–45 s, generally not recommended for football), and game-based formats such as SSG (Buchheit & Laursen, 2022). The match between type and format is not one-to-one: the same physiological target can be achieved through multiple formats, and the choice depends on concurrent neuromuscular load, injury risk, and tactical integration priorities.

Early preseason programming favours Type 1 HIIT combined with SSG formats (6v6 to 8v8) that deliver aerobic stimuli with controlled neuromuscular and locomotor loads. As the preparation period progresses, Type 4 HIIT and dedicated sprint work are gradually introduced to develop the anaerobic and neuromuscular capacities required for match demands (Buchheit & Laursen, 2022). This progression mirrors the general-to-specific transition at the conditioning level.

Speed endurance (SE) training divides into two distinct modalities with different physiological targets.

Parameter	SE Maintenance	SE Production
Format	SSG (2v2–4v4)	Individual drills
Intensity	70–90%	90–100%
Duration	1–4 min	<30 s
Work:Rest	~1:3	>1:4
Sets	4–5	Individualised

SE maintenance preserves the aerobic-anaerobic base across the week, while SE production develops the capacity to produce repeated high-speed efforts under fatigue—a quality directly relevant to match performance (Read et al., 2023).

Managing high-speed running (HSR) load during preseason requires attention to both volume and intensity. HIIT sessions can replicate a full match’s HSR volume in under 15 minutes, but at intensities substantially exceeding match peaks (Buchheit & Laursen, 2022). Practitioners face a design choice: longer sets (4–6+ minutes) prioritise metabolic conditioning, while shorter sets (3–4 minutes) better replicate match-specific intensity profiles. The within-session puzzle adds further complexity. Before selecting the HIIT component, practitioners must evaluate the neuromuscular load imposed by any preceding tactical drill sequence. If the tactical block already stressed the posterior chain heavily through accelerations, decelerations, and direction changes, the HIIT selection should shift towards formats that minimise additional mechanical work to protect against hamstring overload (Buchheit & Laursen, 2022).

Compensatory training addresses HSR deficits for players who receive insufficient match or training exposure. Bench players and substitutes accumulate lower weekly HSR volumes, creating acute-to-chronic load imbalances that elevate injury risk. Structured HIIT top-ups—typically Type 2 running-based formats—stabilise their HSR load at levels consistent with the squad’s chronic training baseline (Buchheit & Laursen, 2022).

Confirming Adaptation: Monitoring, Recovery, and Achieving Match Readiness

The theoretical models underpinning training management—the General Adaptation Syndrome (GAS) and the Fitness-Fatigue Model—describe how training stimuli produce competing fitness and fatigue effects that decay at different rates, with fatigue dissipating approximately twice as fast as fitness gains (Cormack & Coutts, 2022). Monitoring during preseason serves a different purpose than in-season tracking. Rather than managing fatigue around fixtures, preseason monitoring confirms that the planned training programme is producing the intended adaptations. This distinction reflects a broader paradigm shift from fatigue-based monitoring towards training-effects-based monitoring, where readiness is understood as an operational proxy for the quality of adaptation, not merely the absence of fatigue (Rebelo et al., 2026).

Integrated monitoring combines external load (GPS-derived distances, speeds, accelerations) with internal load (heart rate, sRPE) to produce a complete picture of the training stimulus and the athlete’s response. When a standardised external load produces a decreasing internal response over time, fitness is improving. When internal load rises relative to a stable external stimulus, either fitness is declining or fatigue is accumulating (Impellizzeri et al., 2019). The EL/IL ratio provides a practical fitness indicator: low external load paired with high internal load signals poor fitness and elevated injury risk under high training exposure (Pillitteri et al., 2024).

Neuromuscular monitoring through the countermovement jump (CMJ) is the most frequently studied readiness assessment tool. CMJ height provides a general index of neuromuscular function, while derived variables such as RSImod (reactive strength index modified) and RFD offer greater sensitivity to neuromuscular fatigue and adaptation (Riboli et al., 2023). A combined battery of CMJ height, RSImod, and sRPE delivers an efficient, time-effective monitoring system suitable for daily use across a full squad.

The MAA framework—Minimal, Adequate, and Accurate—guides monitoring tool selection. A minimal system includes sRPE and total distance. An adequate system adds HSR distance, CMJ, and wellness questionnaires. An accurate system incorporates force-velocity profiling, HRV, and biochemical markers (Rebelo et al., 2026). Most preseason environments operate at the adequate level, reserving accurate-level tools for targeted investigations or high-risk individuals. Individualised thresholds—typically ±1 standard deviation from personal baselines—provide the decision-making trigger for load adjustment, chosen to minimise Type II errors (missing a genuine maladaptation signal) at the acceptable cost of occasional false positives (Rebelo et al., 2026).

Recovery during preseason prioritises sleep as the single most effective strategy. Athletes in preseason should target 8–10 hours nightly, exceeding the general 7–9 hour recommendation to support elevated training demands and accelerated adaptation (Tavares et al., 2023). Carbohydrate periodisation aligns intake with training objectives: higher carbohydrate availability (6–8 g/kg body weight) on high-load days and reduced intake (3–6 g/kg) on low-load or recovery days. Protein distribution across 4–5 meals at approximately 0.4 g/kg per meal supports muscle protein synthesis throughout the day (Tavares et al., 2023).

Cold water immersion (CWI) requires careful timing during preseason. When the training objective is hypertrophy—common in early general preparation—CWI may attenuate the inflammatory signalling cascade that drives muscle growth. Practitioners should limit CWI use during hypertrophy-focused mesocycles and reserve it for phases where recovery speed outweighs adaptation maximisation (Tavares et al., 2023).

As preseason concludes, practitioners select a microcycle lead-in model that will govern the in-season training structure. The four-day lead-in (MD−4 through MD−1) represents the most widely adopted structure at the elite level, distributing training across narrow-area sessions (MD−4), wide-area sessions (MD−3), speed and tactical sessions (MD−2), and reactive preparatory work (MD−1). Establishing this rhythm during the final weeks of preseason ensures a smooth transition into the competitive phase (Read et al., 2023).

Preseason training camps in hot environments offer dual adaptation value. A study of elite soccer players undertaking a competitive preseason camp in tropical conditions demonstrated approximately 3% reduction in submaximal heart rate and 19% improvement in neuromuscular efficiency within just eight days, confirming that well-structured camps can simultaneously advance conditioning and heat acclimatisation goals (Buchheit et al., 2016).

Periodisation ultimately functions as a flexible scaffolding framework, not a rigid prescription (Haff, 2022). Microcycle sequencing should be adjusted based on monitoring data, with the athlete’s internal response serving as the primary basis for programming modifications throughout the preparation period.

Key Takeaways

• Preseason corresponds to the preparation period within the macrocycle and should be designed as a flexible scaffolding, transitioning from general preparation (high volume, low intensity) to specific preparation (sport-specific, high intensity).
• On the first day of preseason, prioritise submaximal tests and injury risk screening; introduce maximal output tests gradually after players adapt to initial training stimuli. The 30-15 IFT simultaneously provides profiling and HIIT prescription through V_IFT.
• Build the aerobic base using the LSG→MSG→SSG transition model; design strength-power programmes individualised from preseason screening, incorporating core exercises (TBD, RDL, NHE) and eccentric training for injury risk reduction.
• Programme HIIT by the “physiology first” principle—define the physiological target (Type 1–6) before selecting the format. Begin preseason with Type 1 HIIT and SSG, gradually introducing Type 4 and sprint work.
• Preseason monitoring integrates external and internal loads, using CMJ-based readiness assessment and sRPE alongside sleep (8–10 hours), nutrition (carbohydrate periodisation), and appropriately timed cooling modalities to confirm adaptation and achieve match readiness.
