Microdosing Resistance Training in Football: Can Less Really Be More During the Season?

Modern football has changed dramatically over the past decade. Players now sprint more often, cover greater high-intensity distances, and face increasingly congested fixture schedules. Between league matches, cup competitions, international travel, tactical preparation, recovery sessions, media obligations, and rehabilitation work, the traditional model of lengthy gym-based strength sessions is becoming harder to sustain during the competitive season. At the same time, the physical demands of elite football continue to rise. Professional players regularly cover 10–13 km per match, with repeated bouts of high-speed running, sprinting, acceleration, deceleration, and changes of direction placing substantial stress on the neuromuscular system (Bloomfield et al., 2007; Rampinini et al., 2007). Recent evidence also suggests that elite football is becoming increasingly physically demanding, with players performing more high-intensity running and sprinting actions than ever before (Allen et al., 2024; Barnes et al., 2014). Strength and conditioning coaches therefore face a difficult balancing act of how to maintain strength, power, and injury resilience without creating excessive fatigue. One increasingly popular solution is “microdosing” resistance training.

Microdosing refers to the distribution of smaller, more frequent resistance training sessions across the week, rather than relying on one or two high-volume gym sessions. Borrowed from pharmacology, the concept aims to provide enough stimulus to maintain or improve adaptation while minimizing fatigue, soreness, and disruption to performance (Cuthbert et al., 2024). Although the concept is relatively new in sports science literature, microdosing is already widely used in elite football environments. The growing interest in this approach raises an important question... Can small, strategically timed doses of resistance training preserve physiological adaptation throughout the season?

Why Strength Training Matters In-Season

Resistance training is fundamental to athletic performance. Stronger athletes generally sprint faster, jump higher, tolerate greater training loads, and demonstrate improved change-of-direction ability (Suchomel et al., 2016). In football specifically, muscular strength is strongly linked to acceleration, deceleration, and injury prevention (Beato et al., 2021). Traditionally, football teams use pre-season to build physical qualities such as maximal strength, power, and muscle mass. During the season, however, the focus often shifts toward maintaining these adaptations while prioritizing match readiness (Darragi et al., 2024). This creates a significant challenge because the body rapidly loses physical qualities when training stimuli are reduced.

Research on detraining consistently shows declines in muscle cross-sectional area, eccentric force production, power output, and sport-specific strength after periods of insufficient resistance training (Mujika & Padilla, 2001). Even relatively short periods without adequate loading can reduce neuromuscular performance (Hortobágyi et al., 1993; Neufer et al., 1987). Longer interruptions can lead to substantial losses in strength and power alongside increased injury risk (McMaster et al., 2013).

This is particularly concerning in football, where many of the most severe injuries are non-contact in nature (Wong & Hong, 2005). Hamstring strains, groin injuries, and tendon-related problems are often linked to insufficient strength or poor load management (Bahr & Krosshaug, 2005; Buckthorpe, 2019). As fixture congestion increases, the risk of underdosing strength work becomes increasingly relevant.

What Is Microdosing Resistance Training?

Microdosing resistance training involves spreading weekly training volume across multiple shorter sessions. Instead of one heavy 60–90 minute gym session, players may complete several 10–25 minute sessions throughout the week.

The total training volume may remain similar, but each session is designed to minimize neuromuscular fatigue and delayed onset muscle soreness (DOMS). In practical football settings, this often means fewer exercises per session, lower repetition volumes, strategic exercise selection, reduced eccentric loading and greater use of isometric or concentric-focused work. The goal is to provide enough stimulus to preserve or enhance adaptation while maintaining readiness for competition. This approach is especially useful during congested schedules, such as two- or three-game weeks, where recovery time is limited.

The Neurological Adaptations Behind Strength Maintenance

One of the key reasons it has been suggested that microdosing may work lies in the nervous system. Strength is not simply a product of muscle size. Neural adaptation plays a major role in force production, particularly in trained athletes (Sale, 1988). Resistance training improves the ability of the central nervous system to recruit motor units efficiently, increase firing frequency, and enhance rate of force development (Aagaard et al., 2002a; Del Vecchio et al., 2019). Motor units are recruited according to the “size principle,” meaning smaller units are activated before larger, higher-threshold units (Henneman et al., 1965). With training, athletes become more efficient at recruiting these high-threshold motor units quickly and consistently.

This is highly relevant in football, where explosive actions such as sprinting, jumping, tackling, and rapid acceleration depend heavily on rapid force production. Importantly, neural adaptations appear to respond well to frequent exposure. Regular low-volume sessions may help maintain motor unit recruitment patterns and neuromuscular coordination without inducing excessive fatigue (Akbar et al., 2022). Microdosing may therefore be particularly effective for preserving qualities such as sprint acceleration, rate of force development, reactive strength, movement efficiency and change of direction. For elite footballers who already possess substantial muscle mass and training history, maintaining neural efficiency may be as important as pursuing hypertrophy during the season.

Morphological Adaptations: Can Small Doses Preserve Muscle?

While neural factors are critical, muscle morphology also contributes to performance. Resistance training stimulates muscle protein synthesis and structural adaptations that increase force production. These include increases in muscle cross-sectional area, tendon stiffness, pennation angle, and connective tissue resilience (Schoenfeld, 2010). Traditionally, higher volume resistance training has been associated with greater hypertrophic responses. However, emerging evidence suggests that comparable muscle growth can occur across a range of loading schemes, provided sufficient intensity and effort are achieved (Schoenfeld et al., 2021).

This has important implications for microdosing. Although short sessions may not maximize hypertrophy, they may still provide enough stimulus to preserve muscle mass and connective tissue integrity during the season. Even submaximal adaptations may be sufficient to prevent detraining. Importantly, maintaining tendon stiffness is also highly relevant for football performance. Stiffer tendons improve force transmission and elastic energy return, both of which contribute to sprinting and jumping efficiency (Werkhausen et al., 2019).

The Problem With Fatigue

One of the strongest arguments for microdosing is fatigue management. Traditional high volume resistance training often produces substantial muscle soreness and exercise-induced muscle damage, especially when eccentric contractions are emphasized (Hody et al., 2019). While this may be acceptable during pre-season, it becomes problematic when players must perform maximally every few days. Excessive fatigue can negatively affect sprint performance, technical execution, recovery, sleep quality, match readiness and injury risk. Microdosing aims to reduce these negative side effects while still maintaining adaptation.

This aligns with modern performance models that emphasize athlete availability as a key performance indicator. In elite football, a player who is slightly undertrained but consistently available may provide greater value than one who is physically optimized but frequently injured (Gabbett, 2020).

Which Types of Contractions Work Best?

The type of muscle contraction used during microdosed sessions is an important consideration.

Eccentric Training

Eccentric contractions can produce significant strength and hypertrophy adaptations. They are also highly effective for improving braking force and tendon remodeling (Hody et al., 2019). However, eccentric training is strongly associated with muscle soreness and exercise induced muscle damage. Because of this, heavily eccentric-focused sessions are often avoided during congested fixture periods.

Isometric Training

Isometric training has become increasingly popular in elite football because it can generate high force outputs with relatively low fatigue cost. Research suggests that isometric work can improve tendon stiffness, maximal force production, joint stability and neuromuscular activation. Importantly, isometric contractions typically produce less soreness than eccentric loading. Isometric split squats, Copenhagen holds, mid thigh pull variations, soleus holds and glute bridge holds are now commonly used in microdosing strategies across football.

Concentric-Focused Training

Concentric training also appears useful during the season because it generally produces less muscle damage than eccentric work. Lo volume concentric focused lifting can help maintain neural drive and strength qualities without compromising recovery.

Does Training Frequency Matter?

Research suggests that even one high intensity strength session per week may be sufficient to maintain strength adaptations during the season (Rønnestad et al., 2011). However, microdosing may offer additional advantages because the stimulus is distributed more evenly throughout the week. Rather than creating one large fatigue spike, athletes receive multiple smaller exposures that may better support neuromuscular maintenance. This becomes especially useful during congested schedules where time-efficient sessions are required. The cumulative effect may preserve adaptation while reducing recovery burden.

For example, instead of one 75-minute gym session, players might complete:

• A 15-minute isometric session post-training

• A short neural activation lift on matchday minus two

• A micro plyometric exposure later in the week

Practical Applications in Football

Microdosing is highly adaptable and can be individualized based on fixture congestion, player position, injury history, and training age. Common targets in football include hamstrings, quadriceps, adductors, calves and glutes. These muscle groups are frequently associated with sprinting, deceleration, and common non-contact injuries. Therefore, typical microdosed sessions may include isometric calf holds, Copenhagen adduction work, split squat isometrics, single-leg squat holds, hamstring bridge variations and low volume plyometrics

Volume is usually intentionally low. For example 2 sets of 4 reps, 10–30 second isometric holds, high intensity with minimal total repetitions. The emphasis is on quality rather than quantity.

Meta-analyses examining minimum effective dose training suggest that relatively small volumes of high intensity work can still produce meaningful strength improvements in trained populations (Androulakis-Korakakis et al., 2020; 2021). However, the precise minimum effective dose for elite footballers across a competitive season remains unclear.

Limitations and Unanswered Questions

Despite growing enthusiasm, research on microdosing remains limited.

Many studies examine short-term interventions rather than full competitive seasons. There is also significant variation in how microdosing is implemented across teams and studies.

Several important questions remain unanswered:

• What is the minimum effective dose for elite athletes?

• How should microdosing be periodised across congested schedules?

• Which contraction types are most effective?

• How do individual responses differ?

• Can microdosing improve performance, or only maintain it?

There is also a risk that poorly designed microdosing programs may still generate excessive fatigue if intensity is too high or recovery insufficient. Ultimately, microdosing should not be viewed as a shortcut or replacement for robust strength training. Instead, it should be seen as a strategic tool that allows practitioners to maintain adaptation when traditional methods become impractical.

Conclusion

Microdosing resistance training represents a modern response to the realities of elite football. As match demands continue to increase, practitioners must find ways to preserve strength, power, and injury resilience without compromising performance or recovery. The available evidence suggests that smaller, more frequent resistance training exposures may help maintain neuromuscular and morphological adaptations during the season while reducing fatigue and soreness. The approach appears particularly useful during congested fixture periods where traditional high-volume lifting is unrealistic. However, microdosing is not a 'one-size-fits-all' solution. Its effectiveness depends heavily on exercise selection, intensity, contraction type, volume distribution, and the individual needs of the athlete.

For now, the evidence suggests that in elite football, less may sometimes be more ... provided the dose is carefully prescribed.
