Isometric Training for Football - Fad or Future?
In elite football circles, isometric training has resurfaced as a key tool in strength and rehab programming.
From early-stage tendon loading to in-season strength retention, its appeal lies in high stimulus with low mechanical cost. But is it a science-supported strategy or just another fad?
What Are Isometrics, and Why Should We Care?
Isometric exercises involve force production without a change in muscle length. Unlike concentric or eccentric work, these exercises include holding or pushing against an immovable object. The two main types:
Yielding Isometrics: Holding a static position (e.g., wall sit, Spanish squat)
Overcoming Isometrics: Pushing maximally against an immovable resistance (e.g., isometric mid-thigh pull)
In football, they offer:
High force production with low fatigue
Minimal joint stress
Versatility across pre-season, in-season, and return-to-play phases
The Evidence Behind the Practice
The scientific case for isometric training is growing stronger. One of the most compelling areas is tendon adaptation.
Research by Bohm et al. and others demonstrates that isometric loading can significantly enhance tendon stiffness—an important quality for athletes dealing with patellar or Achilles tendinopathy.
Isometrics offer a safe and effective way to apply load without aggravating the tendon, making them ideal for early-stage rehabilitation.
Isometric exercises are also being recognised for their ability to preserve maximal strength. Lum et al. (2020) found that isometric protocols can maintain or even improve strength levels when athletes are unable to lift heavy loads due to fixture congestion or fatigue. This makes them particularly valuable during the in-season period, where neuromuscular freshness is a priority.
Finally, there's compelling evidence around pain modulation. Isometric holds, especially for the quadriceps and hamstrings, have been shown to produce an acute analgesic effect.
This can help athletes continue training or competing while managing chronic tendon discomfort. The work of Rio et al. (2015) in this space has been particularly influential.
When and How to Use Isometrics
In the pre-season, isometrics can be used to build maximal strength through exercises like the isometric mid-thigh pull or split squat hold. Recommended dosages include 3–5 repetitions of 3–5 seconds, performed twice per week.
During the in-season, when managing cumulative fatigue is crucial, isometrics such as the IMTP or overcoming lunge holds offer a way to maintain strength. These can be programmed for 2–3 repetitions of 2–3 seconds, one to two times per week.
For rehabilitation or return-to-play scenarios, yielding isometrics like the Spanish squat or isometric hamstring bridge are effective in loading tendons safely. These are often prescribed as three 45-second holds, either daily or every other day, depending on tolerance.
In pre-match contexts, brief isometric holds can serve as a neuromuscular primer. A common option is the lunge hold with band drive, performed for two 20-second holds per leg on the day before competition (MD-1).
Limitations and Considerations
While isometric training provides many benefits, it is not a comprehensive replacement for concentric and eccentric loading—particularly when it comes to developing muscle hypertrophy and explosive power.
Its utility lies in complementing dynamic strength training, not substituting it entirely. For the best results, isometrics should be strategically integrated into a broader program that includes a range of contraction types and movement velocities.
Another key consideration is monitoring. Despite their relatively low fatigue cost, excessive use of isometrics—especially when not periodized appropriately—can lead to joint stiffness or reduced readiness. Coaches must evaluate how these exercises interact with the total training load and recovery status of the athlete.
Bottom Line
Isometric training offers real, evidence-based benefits for footballers—particularly in contexts where load tolerance, tendon health, or recovery timelines are constrained. When programmed intelligently, it's a powerful addition to your performance toolkit.
In the balance between hype and utility, isometrics are no fad. They're a refined strategy with growing support from both science and elite-level practice.
That's all for today.
See you next Friday.
