In Focus: Venn Healthcare - Players “Can’t Switch Off”

Why elite football is turning to nervous system recovery.

fcbusiness speaks to Jenny Torney, Clinical Lead for NESA XSignal, about sleep disruption, nervous system overload and why neuromodulation is becoming one of football’s fastest-growing recovery conversations.

Elite football has become incredibly sophisticated when it comes to physical performance. Most clubs now operate with advanced load monitoring, GPS tracking, nutrition protocols, recovery systems and highly developed strength and conditioning departments.

But despite all that investment and data, the same issues continue to surface repeatedly across elite environments: poor sleep, accumulated fatigue, difficulty switching off after matches and players never quite feeling fully recovered during intense periods of the season.

That growing concern around recovery quality, not just physical recovery, is one of the reasons technologies such as NESA XSignal are beginning to attract increasing attention within professional football. For Jenny Torney, Clinical Lead for NESA XSignal, the conversation around recovery is changing rapidly.

“The biggest shift we are seeing is clubs beginning to understand that physical recovery and nervous system recovery are not always the same thing,” she explains. “A player may appear physically recovered, but the nervous system can still remain highly stimulated underneath.

“That ongoing sympathetic activation, essentially staying in a constant ‘fight or flight’ state, can affect sleep quality, recovery response and overall readiness to perform.”

That issue becomes particularly visible during congested fixture periods. – Sleep quality deteriorates. – Recovery windows shrink. – HRV can remain suppressed. – Fatigue accumulates more quickly. – Players struggle to properly downregulate after evening matches.

Modern footballers are now operating under relentless physical and psychological demands. Travel schedules, evening kick-offs, media scrutiny, social media exposure and constant performance pressure all contribute to elevated nervous system stress across a season.

Sports science research has increasingly linked poor sleep with impaired cognitive performance, slower recovery, reduced reaction times and increased injury risk in athletes.

Research from Stanford University also demonstrated improvements in sprint performance, reaction time and shooting accuracy following sleep extension interventions. At the same time, there is growing discussion within elite sport around the relationship between chronic sympathetic nervous system activation, persistent pain states and failed recovery patterns.

“More practitioners are beginning to recognise that recovery is not simply about local tissue overload,” says Torney. “Poor sleep, chronic stress and nervous system dysregulation may all influence recovery quality and pain sensitivity in certain athletes. The nervous system sits underneath so much of the recovery process itself.”

That is where NESA XSignal enters the conversation. Unlike many technologies used within elite sport, NESA does not directly target muscles, tendons or injury sites. Instead, the system was developed around autonomic nervous system modulation using ultra-low microcurrents delivered through electrodes placed on the hands and feet.

“The emphasis is regulation rather than stimulation,” explains Torney. “The system works through sensory nerve pathways and the autonomic nervous system with the aim of helping reduce excessive sympathetic activation and supporting a more balanced recovery state.”

That difference is one of the reasons conversations around NESA within football are increasingly centred around sleep quality, recovery state and nervous system regulation rather than traditional injury treatment alone.

Torney believes football is only at the beginning of understanding how influential autonomic regulation may become within elite performance environments.

“The more we understand the nervous system, the more we realise how central it is to recovery, stress regulation and performance itself,” she says. “I think football is gradually moving away from viewing recovery purely through a mechanical lens. Clubs are starting to look more closely at the systems sitting underneath performance.”

Published research associated with NESA has also explored sleep and recovery markers within elite athletes. One preliminary study involving professional basketball players reported improvements in total sleep duration, REM sleep variables and recovery markers during periods of intensive competition, alongside cortisol normalisation during playoff periods.

For elite football clubs, where fixture congestion continues to intensify and recovery windows become increasingly compressed, those conversations are becoming harder to ignore.

Sessions themselves are also very different from what many athletes expect. Rather than aggressive stimulation or physically demanding recovery protocols, NESA sessions are generally quiet, non-invasive and recovery focused, with athletes typically seated or reclined during treatment.

“In elite sport, athletes are constantly exposed to physical loading, gym work, manual therapy and high-intensity inputs,” says Torney. “NESA provides a very different recovery environment. That softer neurological approach is one of the reasons it is attracting interest inside high-performance sport.”

The technology has already been used within several elite football and high-performance environments across Spain and Portugal, including organisations linked with LaLiga, clubs including FC Barcelona alongside wider use across professional sport and rehabilitation settings.

Importantly for elite clubs, NESA XSignal can also be integrated easily into existing recovery environments. Systems are now being used within dedicated recovery and sleep pod settings at training grounds, allowing players to incorporate sessions into daily recovery schedules around training and match preparation.

The portability of the technology also allows players to continue sessions away from the training ground, including at home and during travel periods, helping maintain consistency during congested fixture schedules and optimising recovery outcomes across the season.

As recovery science continues to evolve, many within football now believe the future of performance support may extend far beyond muscles, joints and traditional recovery models alone.

“The conversation is changing,” says Torney. “It is becoming less about isolated tissue treatment and more about recovery quality, nervous system regulation and helping athletes cope with the cumulative demands of elite competition.

“And with modern football becoming more intense every season, those conversations are only going to become more important.”
